+Version 2.7.0 beta3
+-------------------
+
+*(Released Mon, 22 Apr 2013)*
+
+Incompatible/important changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Instance policies for disk size were documented to be on a per-disk
+ basis, but hail applied them to the sum of all disks. This has been
+ fixed.
+- ``hbal`` will now exit with status 0 if, during job execution over
+ LUXI, early exit has been requested and all jobs are successful;
+ before, exit status 1 was used, which cannot be differentiated from
+ "job error" case
+- Compatibility with newer versions of rbd has been fixed
+- ``gnt-instance batch-create`` has been changed to use the bulk create
+ opcode from Ganeti. This lead to incompatible changes in the format of
+ the JSON file. It's now not a custom dict anymore but a dict
+ compatible with the ``OpInstanceCreate`` opcode.
+- Parent directories for file storage need to be listed in
+ ``$sysconfdir/ganeti/file-storage-paths`` now. ``cfgupgrade`` will
+ write the file automatically based on old configuration values, but it
+ can not distribute it across all nodes and the file contents should be
+ verified. Use ``gnt-cluster copyfile
+ $sysconfdir/ganeti/file-storage-paths`` once the cluster has been
+ upgraded. The reason for requiring this list of paths now is that
+ before it would have been possible to inject new paths via RPC,
+ allowing files to be created in arbitrary locations. The RPC protocol
+ is protected using SSL/X.509 certificates, but as a design principle
+ Ganeti does not permit arbitrary paths to be passed.
+- The parsing of the variants file for OSes (see
+ :manpage:`ganeti-os-interface(7)`) has been slightly changed: now empty
+ lines and comment lines (starting with ``#``) are ignored for better
+ readability.
+- The ``setup-ssh`` tool added in Ganeti 2.2 has been replaced and is no
+ longer available. ``gnt-node add`` now invokes a new tool on the
+ destination node, named ``prepare-node-join``, to configure the SSH
+ daemon. Paramiko is no longer necessary to configure nodes' SSH
+ daemons via ``gnt-node add``.
+- Draining (``gnt-cluster queue drain``) and un-draining the job queue
+ (``gnt-cluster queue undrain``) now affects all nodes in a cluster and
+ the flag is not reset after a master failover.
+- Python 2.4 has *not* been tested with this release. Using 2.6 or above
+ is recommended. 2.6 will be mandatory from the 2.8 series.
+
+
+New features
+~~~~~~~~~~~~
+
+- New network management functionality to support automatic allocation
+ of IP addresses and managing of network parameters. See
+ :manpage:`gnt-network(8)` for more details.
+- New external storage backend, to allow managing arbitrary storage
+ systems external to the cluster. See
+ :manpage:`ganeti-extstorage-interface(7)`.
+- New ``exclusive-storage`` node parameter added, restricted to
+ nodegroup level. When it's set to true, physical disks are assigned in
+ an exclusive fashion to instances, as documented in :doc:`Partitioned
+ Ganeti <design-partitioned>`. Currently, only instances using the
+ ``plain`` disk template are supported.
+- The KVM hypervisor has been updated with many new hypervisor
+ parameters, including a generic one for passing arbitrary command line
+ values. See a complete list in :manpage:`gnt-instance(8)`.
+- A new tool, called ``mon-collector``, is the stand-alone executor of
+ the data collectors for a monitoring system. As of this version, it
+ just includes the DRBD data collector, that can be executed by calling
+ ``mon-collector`` using the ``drbd`` parameter. See
+ :manpage:`mon-collector(7)`.
+- A new user option, :pyeval:`rapi.RAPI_ACCESS_READ`, has been added
+ for RAPI users. It allows granting permissions to query for
+ information to a specific user without giving
+ :pyeval:`rapi.RAPI_ACCESS_WRITE` permissions.
+- A new tool named ``node-cleanup`` has been added. It cleans remains of
+ a cluster from a machine by stopping all daemons, removing
+ certificates and ssconf files. Unless the ``--no-backup`` option is
+ given, copies of the certificates are made.
+- Instance creations now support the use of opportunistic locking,
+ potentially speeding up the (parallel) creation of multiple instances.
+ This feature is currently only available via the :doc:`RAPI
+ <rapi>` interface and when an instance allocator is used. If the
+ ``opportunistic_locking`` parameter is set the opcode will try to
+ acquire as many locks as possible, but will not wait for any locks
+ held by other opcodes. If not enough resources can be found to
+ allocate the instance, the temporary error code
+ :pyeval:`errors.ECODE_TEMP_NORES` is returned. The operation can be
+ retried thereafter, with or without opportunistic locking.
+- New experimental linux-ha resource scripts.
+- Restricted-commands support: ganeti can now be asked (via command line
+ or rapi) to perform commands on a node. These are passed via ganeti
+ RPC rather than ssh. This functionality is restricted to commands
+ specified on the ``$sysconfdir/ganeti/restricted-commands`` for security
+ reasons. The file is not copied automatically.
+
+
+Misc changes
+~~~~~~~~~~~~
+
+- Diskless instances are now externally mirrored (Issue 237). This for
+ now has only been tested in conjunction with explicit target nodes for
+ migration/failover.
+- Queries not needing locks or RPC access to the node can now be
+ performed by the confd daemon, making them independent from jobs, and
+ thus faster to execute. This is selectable at configure time.
+- The functionality for allocating multiple instances at once has been
+ overhauled and is now also available through :doc:`RAPI <rapi>`.
+
+Since beta2:
+
+- Fix hail to verify disk instance policies on a per-disk basis (Issue 418).
+- Fix data loss on wrong usage of ``gnt-instance move``
+- Properly export errors in confd-based job queries
+- Add ``users-setup`` tool
+- Fix iallocator protocol to report 0 as a disk size for diskless
+ instances. This avoids hail breaking when a diskless instance is
+ present.
+- Fix job queue directory permission problem that made confd job queries
+ fail. This requires running an ``ensure-dirs --full-run`` on upgrade
+ for access to archived jobs (Issue 406).
+- Limit the sizes of networks supported by ``gnt-network`` to something
+ between a ``/16`` and a ``/30`` to prevent memory bloat and crashes.
+- Fix bugs in instance disk template conversion
+- Fix GHC 7 compatibility
+- Fix ``burnin`` install path (Issue 426).
+- Allow very small disk grows (Issue 347).
+- Fix a ``ganeti-noded`` memory bloat introduced in 2.5, by making sure
+ that noded doesn't import masterd code (Issue 419).
+- Make sure the default metavg at cluster init is the same as the vg, if
+ unspecified (Issue 358).
+- Fix cleanup of partially created disks (part of Issue 416)
+
+
+Version 2.7.0 beta2
+-------------------
+
+*(Released Tue, 2 Apr 2013)*
+
+This was the second beta release of the 2.7 series. Since beta1:
+
+- Networks no longer have a "type" slot, since this information was
+ unused in Ganeti: instead of it tags should be used.
+- The rapi client now has a ``target_node`` option to MigrateInstance.
+- Fix early exit return code for hbal (Issue 386).
+- Fix ``gnt-instance migrate/failover -n`` (Issue 396).
+- Fix ``rbd showmapped`` output parsing (Issue 312).
+- Networks are now referenced indexed by UUID, rather than name. This
+ will require running cfgupgrade, from 2.7.0beta1, if networks are in
+ use.
+- The OS environment now includes network information.
+- Deleting of a network is now disallowed if any instance nic is using
+ it, to prevent dangling references.
+- External storage is now documented in man pages.
+- The exclusive_storage flag can now only be set at nodegroup level.
+- Hbal can now submit an explicit priority with its jobs.
+- Many network related locking fixes.
+- Bump up the required pylint version to 0.25.1.
+- Fix the ``no_remember`` option in RAPI client.
+- Many ipolicy related tests, qa, and fixes.
+- Many documentation improvements and fixes.
+- Fix building with ``--disable-file-storage``.
+- Fix ``-q`` option in htools, which was broken if passed more than
+ once.
+- Some haskell/python interaction improvements and fixes.
+- Fix iallocator in case of missing LVM storage.
+- Fix confd config load in case of ``--no-lvm-storage``.
+- The confd/query functionality is now mentioned in the security
+ documentation.
+
+
+Version 2.7.0 beta1
+-------------------
+
+*(Released Wed, 6 Feb 2013)*
+
+This was the first beta release of the 2.7 series. All important changes
+are listed in the latest 2.7 entry.
+
+
+Version 2.6.2
+-------------
+
+*(Released Fri, 21 Dec 2012)*
+
+Important behaviour change: hbal won't rebalance anymore instances which
+have the ``auto_balance`` attribute set to false. This was the intention
+all along, but until now it only skipped those from the N+1 memory
+reservation (DRBD-specific).
+
+A significant number of bug fixes in this release:
+
+- Fixed disk adoption interaction with ipolicy checks.
+- Fixed networking issues when instances are started, stopped or
+ migrated, by forcing the tap device's MAC prefix to "fe" (issue 217).
+- Fixed the warning in cluster verify for shared storage instances not
+ being redundant.
+- Fixed removal of storage directory on shared file storage (issue 262).
+- Fixed validation of LVM volume group name in OpClusterSetParams
+ (``gnt-cluster modify``) (issue 285).
+- Fixed runtime memory increases (``gnt-instance modify -m``).
+- Fixed live migration under Xen's ``xl`` mode.
+- Fixed ``gnt-instance console`` with ``xl``.
+- Fixed building with newer Haskell compiler/libraries.
+- Fixed PID file writing in Haskell daemons (confd); this prevents
+ restart issues if confd was launched manually (outside of
+ ``daemon-util``) while another copy of it was running
+- Fixed a type error when doing live migrations with KVM (issue 297) and
+ the error messages for failing migrations have been improved.
+- Fixed opcode validation for the out-of-band commands (``gnt-node
+ power``).
+- Fixed a type error when unsetting OS hypervisor parameters (issue
+ 311); now it's possible to unset all OS-specific hypervisor
+ parameters.
+- Fixed the ``dry-run`` mode for many operations: verification of
+ results was over-zealous but didn't take into account the ``dry-run``
+ operation, resulting in "wrong" failures.
+- Fixed bash completion in ``gnt-job list`` when the job queue has
+ hundreds of entries; especially with older ``bash`` versions, this
+ results in significant CPU usage.
+
+And lastly, a few other improvements have been made:
+
+- Added option to force master-failover without voting (issue 282).
+- Clarified error message on lock conflict (issue 287).
+- Logging of newly submitted jobs has been improved (issue 290).
+- Hostname checks have been made uniform between instance rename and
+ create (issue 291).
+- The ``--submit`` option is now supported by ``gnt-debug delay``.
+- Shutting down the master daemon by sending SIGTERM now stops it from
+ processing jobs waiting for locks; instead, those jobs will be started
+ once again after the master daemon is started the next time (issue
+ 296).
+- Support for Xen's ``xl`` program has been improved (besides the fixes
+ above).
+- Reduced logging noise in the Haskell confd daemon (only show one log
+ entry for each config reload, instead of two).
+- Several man page updates and typo fixes.
+
+
+Version 2.6.1
+-------------
+
+*(Released Fri, 12 Oct 2012)*
+
+A small bugfix release. Among the bugs fixed:
+
+- Fixed double use of ``PRIORITY_OPT`` in ``gnt-node migrate``, that
+ made the command unusable.
+- Commands that issue many jobs don't fail anymore just because some jobs
+ take so long that other jobs are archived.
+- Failures during ``gnt-instance reinstall`` are reflected by the exit
+ status.
+- Issue 190 fixed. Check for DRBD in cluster verify is enabled only when
+ DRBD is enabled.
+- When ``always_failover`` is set, ``--allow-failover`` is not required
+ in migrate commands anymore.
+- ``bash_completion`` works even if extglob is disabled.
+- Fixed bug with locks that made failover for RDB-based instances fail.
+- Fixed bug in non-mirrored instance allocation that made Ganeti choose
+ a random node instead of one based on the allocator metric.
+- Support for newer versions of pylint and pep8.
+- Hail doesn't fail anymore when trying to add an instance of type
+ ``file``, ``sharedfile`` or ``rbd``.
+- Added new Makefile target to rebuild the whole distribution, so that
+ all files are included.
+
+
+Version 2.6.0
+-------------
+
+*(Released Fri, 27 Jul 2012)*
+
+
+.. attention:: The ``LUXI`` protocol has been made more consistent
+ regarding its handling of command arguments. This, however, leads to
+ incompatibility issues with previous versions. Please ensure that you
+ restart Ganeti daemons soon after the upgrade, otherwise most
+ ``LUXI`` calls (job submission, setting/resetting the drain flag,
+ pausing/resuming the watcher, cancelling and archiving jobs, querying
+ the cluster configuration) will fail.
+
+
+New features
+~~~~~~~~~~~~
+
+Instance run status
++++++++++++++++++++
+
+The current ``admin_up`` field, which used to denote whether an instance
+should be running or not, has been removed. Instead, ``admin_state`` is
+introduced, with 3 possible values -- ``up``, ``down`` and ``offline``.
+
+The rational behind this is that an instance being “down” can have
+different meanings:
+
+- it could be down during a reboot
+- it could be temporarily be down for a reinstall
+- or it could be down because it is deprecated and kept just for its
+ disk
+
+The previous Boolean state was making it difficult to do capacity
+calculations: should Ganeti reserve memory for a down instance? Now, the
+tri-state field makes it clear:
+
+- in ``up`` and ``down`` state, all resources are reserved for the
+ instance, and it can be at any time brought up if it is down
+- in ``offline`` state, only disk space is reserved for it, but not
+ memory or CPUs
+
+The field can have an extra use: since the transition between ``up`` and
+``down`` and vice-versus is done via ``gnt-instance start/stop``, but
+transition between ``offline`` and ``down`` is done via ``gnt-instance
+modify``, it is possible to given different rights to users. For
+example, owners of an instance could be allowed to start/stop it, but
+not transition it out of the offline state.
+
+Instance policies and specs
++++++++++++++++++++++++++++
+
+In previous Ganeti versions, an instance creation request was not
+limited on the minimum size and on the maximum size just by the cluster
+resources. As such, any policy could be implemented only in third-party
+clients (RAPI clients, or shell wrappers over ``gnt-*``
+tools). Furthermore, calculating cluster capacity via ``hspace`` again
+required external input with regards to instance sizes.
+
+In order to improve these workflows and to allow for example better
+per-node group differentiation, we introduced instance specs, which
+allow declaring:
+
+- minimum instance disk size, disk count, memory size, cpu count
+- maximum values for the above metrics
+- and “standard” values (used in ``hspace`` to calculate the standard
+ sized instances)
+
+The minimum/maximum values can be also customised at node-group level,
+for example allowing more powerful hardware to support bigger instance
+memory sizes.
+
+Beside the instance specs, there are a few other settings belonging to
+the instance policy framework. It is possible now to customise, per
+cluster and node-group:
+
+- the list of allowed disk templates
+- the maximum ratio of VCPUs per PCPUs (to control CPU oversubscription)
+- the maximum ratio of instance to spindles (see below for more
+ information) for local storage
+
+All these together should allow all tools that talk to Ganeti to know
+what are the ranges of allowed values for instances and the
+over-subscription that is allowed.
+
+For the VCPU/PCPU ratio, we already have the VCPU configuration from the
+instance configuration, and the physical CPU configuration from the
+node. For the spindle ratios however, we didn't track before these
+values, so new parameters have been added:
+
+- a new node parameter ``spindle_count``, defaults to 1, customisable at
+ node group or node level
+- at new backend parameter (for instances), ``spindle_use`` defaults to 1
+
+Note that spindles in this context doesn't need to mean actual
+mechanical hard-drives; it's just a relative number for both the node
+I/O capacity and instance I/O consumption.
+
+Instance migration behaviour
+++++++++++++++++++++++++++++
+
+While live-migration is in general desirable over failover, it is
+possible that for some workloads it is actually worse, due to the
+variable time of the “suspend” phase during live migration.
+
+To allow the tools to work consistently over such instances (without
+having to hard-code instance names), a new backend parameter
+``always_failover`` has been added to control the migration/failover
+behaviour. When set to True, all migration requests for an instance will
+instead fall-back to failover.
+
+Instance memory ballooning
+++++++++++++++++++++++++++
+
+Initial support for memory ballooning has been added. The memory for an
+instance is no longer fixed (backend parameter ``memory``), but instead
+can vary between minimum and maximum values (backend parameters
+``minmem`` and ``maxmem``). Currently we only change an instance's
+memory when:
+
+- live migrating or failing over and instance and the target node
+ doesn't have enough memory
+- user requests changing the memory via ``gnt-instance modify
+ --runtime-memory``
+
+Instance CPU pinning
+++++++++++++++++++++
+
+In order to control the use of specific CPUs by instance, support for
+controlling CPU pinning has been added for the Xen, HVM and LXC
+hypervisors. This is controlled by a new hypervisor parameter
+``cpu_mask``; details about possible values for this are in the
+:manpage:`gnt-instance(8)`. Note that use of the most specific (precise
+VCPU-to-CPU mapping) form will work well only when all nodes in your
+cluster have the same amount of CPUs.
+
+Disk parameters
++++++++++++++++
+
+Another area in which Ganeti was not customisable were the parameters
+used for storage configuration, e.g. how many stripes to use for LVM,
+DRBD resync configuration, etc.
+
+To improve this area, we've added disks parameters, which are
+customisable at cluster and node group level, and which allow to
+specify various parameters for disks (DRBD has the most parameters
+currently), for example:
+
+- DRBD resync algorithm and parameters (e.g. speed)
+- the default VG for meta-data volumes for DRBD
+- number of stripes for LVM (plain disk template)
+- the RBD pool
+
+These parameters can be modified via ``gnt-cluster modify -D …`` and
+``gnt-group modify -D …``, and are used at either instance creation (in
+case of LVM stripes, for example) or at disk “activation” time
+(e.g. resync speed).
+
+Rados block device support
+++++++++++++++++++++++++++
+
+A Rados (http://ceph.com/wiki/Rbd) storage backend has been added,
+denoted by the ``rbd`` disk template type. This is considered
+experimental, feedback is welcome. For details on configuring it, see
+the :doc:`install` document and the :manpage:`gnt-cluster(8)` man page.
+
+Master IP setup
++++++++++++++++
+
+The existing master IP functionality works well only in simple setups (a
+single network shared by all nodes); however, if nodes belong to
+different networks, then the ``/32`` setup and lack of routing
+information is not enough.
+
+To allow the master IP to function well in more complex cases, the
+system was reworked as follows:
+
+- a master IP netmask setting has been added
+- the master IP activation/turn-down code was moved from the node daemon
+ to a separate script
+- whether to run the Ganeti-supplied master IP script or a user-supplied
+ on is a ``gnt-cluster init`` setting
+
+Details about the location of the standard and custom setup scripts are
+in the man page :manpage:`gnt-cluster(8)`; for information about the
+setup script protocol, look at the Ganeti-supplied script.
+
+SPICE support
++++++++++++++
+
+The `SPICE <http://www.linux-kvm.org/page/SPICE>`_ support has been
+improved.
+
+It is now possible to use TLS-protected connections, and when renewing
+or changing the cluster certificates (via ``gnt-cluster renew-crypto``,
+it is now possible to specify spice or spice CA certificates. Also, it
+is possible to configure a password for SPICE sessions via the
+hypervisor parameter ``spice_password_file``.
+
+There are also new parameters to control the compression and streaming
+options (e.g. ``spice_image_compression``, ``spice_streaming_video``,
+etc.). For details, see the man page :manpage:`gnt-instance(8)` and look
+for the spice parameters.
+
+Lastly, it is now possible to see the SPICE connection information via
+``gnt-instance console``.
+
+OVF converter
++++++++++++++
+
+A new tool (``tools/ovfconverter``) has been added that supports
+conversion between Ganeti and the `Open Virtualization Format
+<http://en.wikipedia.org/wiki/Open_Virtualization_Format>`_ (both to and
+from).
+
+This relies on the ``qemu-img`` tool to convert the disk formats, so the
+actual compatibility with other virtualization solutions depends on it.
+
+Confd daemon changes
+++++++++++++++++++++
+
+The configuration query daemon (``ganeti-confd``) is now optional, and
+has been rewritten in Haskell; whether to use the daemon at all, use the
+Python (default) or the Haskell version is selectable at configure time
+via the ``--enable-confd`` parameter, which can take one of the
+``haskell``, ``python`` or ``no`` values. If not used, disabling the
+daemon will result in a smaller footprint; for larger systems, we
+welcome feedback on the Haskell version which might become the default
+in future versions.
+
+If you want to use ``gnt-node list-drbd`` you need to have the Haskell
+daemon running. The Python version doesn't implement the new call.
+
+
+User interface changes
+~~~~~~~~~~~~~~~~~~~~~~
+
+We have replaced the ``--disks`` option of ``gnt-instance
+replace-disks`` with a more flexible ``--disk`` option, which allows
+adding and removing disks at arbitrary indices (Issue 188). Furthermore,
+disk size and mode can be changed upon recreation (via ``gnt-instance
+recreate-disks``, which accepts the same ``--disk`` option).
+
+As many people are used to a ``show`` command, we have added that as an
+alias to ``info`` on all ``gnt-*`` commands.
+
+The ``gnt-instance grow-disk`` command has a new mode in which it can
+accept the target size of the disk, instead of the delta; this can be
+more safe since two runs in absolute mode will be idempotent, and
+sometimes it's also easier to specify the desired size directly.
+
+Also the handling of instances with regard to offline secondaries has
+been improved. Instance operations should not fail because one of it's
+secondary nodes is offline, even though it's safe to proceed.
+
+A new command ``list-drbd`` has been added to the ``gnt-node`` script to
+support debugging of DRBD issues on nodes. It provides a mapping of DRBD
+minors to instance name.
+
+API changes
+~~~~~~~~~~~
+
+RAPI coverage has improved, with (for example) new resources for
+recreate-disks, node power-cycle, etc.
+
+Compatibility
+~~~~~~~~~~~~~
+
+There is partial support for ``xl`` in the Xen hypervisor; feedback is
+welcome.
+
+Python 2.7 is better supported, and after Ganeti 2.6 we will investigate
+whether to still support Python 2.4 or move to Python 2.6 as minimum
+required version.
+
+Support for Fedora has been slightly improved; the provided example
+init.d script should work better on it and the INSTALL file should
+document the needed dependencies.
+
+Internal changes
+~~~~~~~~~~~~~~~~
+
+The deprecated ``QueryLocks`` LUXI request has been removed. Use
+``Query(what=QR_LOCK, ...)`` instead.
+
+The LUXI requests :pyeval:`luxi.REQ_QUERY_JOBS`,
+:pyeval:`luxi.REQ_QUERY_INSTANCES`, :pyeval:`luxi.REQ_QUERY_NODES`,
+:pyeval:`luxi.REQ_QUERY_GROUPS`, :pyeval:`luxi.REQ_QUERY_EXPORTS` and
+:pyeval:`luxi.REQ_QUERY_TAGS` are deprecated and will be removed in a
+future version. :pyeval:`luxi.REQ_QUERY` should be used instead.
+
+RAPI client: ``CertificateError`` now derives from
+``GanetiApiError``. This should make it more easy to handle Ganeti
+errors.
+
+Deprecation warnings due to PyCrypto/paramiko import in
+``tools/setup-ssh`` have been silenced, as usually they are safe; please
+make sure to run an up-to-date paramiko version, if you use this tool.
+
+The QA scripts now depend on Python 2.5 or above (the main code base
+still works with Python 2.4).
+
+The configuration file (``config.data``) is now written without
+indentation for performance reasons; if you want to edit it, it can be
+re-formatted via ``tools/fmtjson``.
+
+A number of bugs has been fixed in the cluster merge tool.
+
+``x509`` certification verification (used in import-export) has been
+changed to allow the same clock skew as permitted by the cluster
+verification. This will remove some rare but hard to diagnose errors in
+import-export.
+
+
+Version 2.6.0 rc4
+-----------------
+
+*(Released Thu, 19 Jul 2012)*
+
+Very few changes from rc4 to the final release, only bugfixes:

+- fixed generation of bash completion to ensure a stable ordering
+- fixed a few typos
+
+
+Version 2.6.0 rc3

+Third release candidate for 2.6. The following changes were done from
+rc3 to rc4:
+
+- Fixed ``UpgradeConfig`` w.r.t. to disk parameters on disk objects.
+- Fixed an inconsistency in the LUXI protocol with the provided
+ arguments (NOT backwards compatible)
+- Fixed a bug with node groups ipolicy where ``min`` was greater than
+ the cluster ``std`` value
+- Implemented a new ``gnt-node list-drbd`` call to list DRBD minors for

+
+And of course various fixes to documentation and improved unittests and
+QA.
+
+
+Version 2.6.0 beta1
+-------------------
+
+*(Released Wed, 23 May 2012)*
+
+First beta release of 2.6. The following changes were done from beta1 to
+beta2:
+
+- integrated patch for distributions without ``start-stop-daemon``
+- adapted example init.d script to work on Fedora
+- fixed log handling in Haskell daemons
+- adapted checks in the watcher for pycurl linked against libnss
+- add partial support for ``xl`` instead of ``xm`` for Xen
+- fixed a type issue in cluster verification
+- fixed ssconf handling in the Haskell code (was breaking confd in IPv6
+ clusters)
+
+Plus integrated fixes from the 2.5 branch:
+
+- fixed ``kvm-ifup`` to use ``/bin/bash``
+- fixed parallel build failures
+- KVM live migration when using a custom keymap
+
+
+Version 2.5.2
+-------------
+
+*(Released Tue, 24 Jul 2012)*
+
+A small bugfix release, with no new features:
+
+- fixed bash-isms in kvm-ifup, for compatibility with systems which use a
+ different default shell (e.g. Debian, Ubuntu)
+- fixed KVM startup and live migration with a custom keymap (fixes Issue
+ 243 and Debian bug #650664)
+- fixed compatibility with KVM versions that don't support multiple boot
+ devices (fixes Issue 230 and Debian bug #624256)
+
+Additionally, a few fixes were done to the build system (fixed parallel
+build failures) and to the unittests (fixed race condition in test for
+FileID functions, and the default enable/disable mode for QA test is now
+customisable).
+
+
+Version 2.5.1
+-------------
+
+*(Released Fri, 11 May 2012)*
+
+A small bugfix release.
+
+The main issues solved are on the topic of compatibility with newer LVM
+releases:
+
+- fixed parsing of ``lv_attr`` field
+- adapted to new ``vgreduce --removemissing`` behaviour where sometimes
+ the ``--force`` flag is needed
+
+Also on the topic of compatibility, ``tools/lvmstrap`` has been changed
+to accept kernel 3.x too (was hardcoded to 2.6.*).
+
+A regression present in 2.5.0 that broke handling (in the gnt-* scripts)
+of hook results and that also made display of other errors suboptimal
+was fixed; the code behaves now like 2.4 and earlier.
+
+Another change in 2.5, the cleanup of the OS scripts environment, is too
+aggressive: it removed even the ``PATH`` variable, which requires the OS
+scripts to *always* need to export it. Since this is a bit too strict,
+we now export a minimal PATH, the same that we export for hooks.
+
+The fix for issue 201 (Preserve bridge MTU in KVM ifup script) was
+integrated into this release.
+
+Finally, a few other miscellaneous changes were done (no new features,
+just small improvements):
+
+- Fix ``gnt-group --help`` display
+- Fix hardcoded Xen kernel path
+- Fix grow-disk handling of invalid units
+- Update synopsis for ``gnt-cluster repair-disk-sizes``
+- Accept both PUT and POST in noded (makes future upgrade to 2.6 easier)
+
+
+Version 2.5.0
+-------------
+
+*(Released Thu, 12 Apr 2012)*
+
+Incompatible/important changes and bugfixes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- The default of the ``/2/instances/[instance_name]/rename`` RAPI
+ resource's ``ip_check`` parameter changed from ``True`` to ``False``
+ to match the underlying LUXI interface.
+- The ``/2/nodes/[node_name]/evacuate`` RAPI resource was changed to use
+ body parameters, see :doc:`RAPI documentation <rapi>`. The server does
+ not maintain backwards-compatibility as the underlying operation
+ changed in an incompatible way. The RAPI client can talk to old
+ servers, but it needs to be told so as the return value changed.
+- When creating file-based instances via RAPI, the ``file_driver``
+ parameter no longer defaults to ``loop`` and must be specified.
+- The deprecated ``bridge`` NIC parameter is no longer supported. Use
+ ``link`` instead.
+- Support for the undocumented and deprecated RAPI instance creation
+ request format version 0 has been dropped. Use version 1, supported
+ since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
+- Pyparsing 1.4.6 or above is required, see :doc:`installation
+ documentation <install>`.
+- The "cluster-verify" hooks are now executed per group by the
+ ``OP_CLUSTER_VERIFY_GROUP`` opcode. This maintains the same behavior
+ if you just run ``gnt-cluster verify``, which generates one opcode per
+ group.
+- The environment as passed to the OS scripts is cleared, and thus no
+ environment variables defined in the node daemon's environment will be
+ inherited by the scripts.
+- The :doc:`iallocator <iallocator>` mode ``multi-evacuate`` has been
+ deprecated.
+- :doc:`New iallocator modes <design-multi-reloc>` have been added to
+ support operations involving multiple node groups.
+- Offline nodes are ignored when failing over an instance.
+- Support for KVM version 1.0, which changed the version reporting format
+ from 3 to 2 digits.
+- TCP/IP ports used by DRBD disks are returned to a pool upon instance
+ removal.
+- ``Makefile`` is now compatible with Automake 1.11.2
+- Includes all bugfixes made in the 2.4 series
+
+New features
+~~~~~~~~~~~~
+
+- The ganeti-htools project has been merged into the ganeti-core source
+ tree and will be built as part of Ganeti (see :doc:`install-quick`).
+- Implemented support for :doc:`shared storage <design-shared-storage>`.
+- Add support for disks larger than 2 TB in ``lvmstrap`` by supporting
+ GPT-style partition tables (requires `parted
+ <http://www.gnu.org/s/parted/>`_).
+- Added support for floppy drive and 2nd CD-ROM drive in KVM hypervisor.
+- Allowed adding tags on instance creation.
+- Export instance tags to hooks (``INSTANCE_TAGS``, see :doc:`hooks`)
+- Allow instances to be started in a paused state, enabling the user to
+ see the complete console output on boot using the console.
+- Added new hypervisor flag to control default reboot behaviour
+ (``reboot_behavior``).
+- Added support for KVM keymaps (hypervisor parameter ``keymap``).
+- Improved out-of-band management support:
+
+ - Added ``gnt-node health`` command reporting the health status of
+ nodes.
+ - Added ``gnt-node power`` command to manage power status of nodes.
+ - Added command for emergency power-off (EPO), ``gnt-cluster epo``.
+
+- Instance migration can fall back to failover if instance is not
+ running.
+- Filters can be used when listing nodes, instances, groups and locks;
+ see :manpage:`ganeti(7)` manpage.
+- Added post-execution status as variables to :doc:`hooks <hooks>`
+ environment.
+- Instance tags are exported/imported together with the instance.
+- When given an explicit job ID, ``gnt-job info`` will work for archived
+ jobs.
+- Jobs can define dependencies on other jobs (not yet supported via
+ RAPI or command line, but used by internal commands and usable via
+ LUXI).
+
+ - Lock monitor (``gnt-debug locks``) shows jobs waiting for
+ dependencies.
+
+- Instance failover is now available as a RAPI resource
+ (``/2/instances/[instance_name]/failover``).
+- ``gnt-instance info`` defaults to static information if primary node
+ is offline.
+- Opcodes have a new ``comment`` attribute.
+- Added basic SPICE support to KVM hypervisor.
+- ``tools/ganeti-listrunner`` allows passing of arguments to executable.
+
+Node group improvements
+~~~~~~~~~~~~~~~~~~~~~~~
+
+- ``gnt-cluster verify`` has been modified to check groups separately,
+ thereby improving performance.
+- Node group support has been added to ``gnt-cluster verify-disks``,
+ which now operates per node group.
+- Watcher has been changed to work better with node groups.
+
+ - One process and state file per node group.
+ - Slow watcher in one group doesn't block other group's watcher.
+
+- Added new command, ``gnt-group evacuate``, to move all instances in a
+ node group to other groups.
+- Added ``gnt-instance change-group`` to move an instance to another
+ node group.
+- ``gnt-cluster command`` and ``gnt-cluster copyfile`` now support
+ per-group operations.
+- Node groups can be tagged.
+- Some operations switch from an exclusive to a shared lock as soon as
+ possible.
+- Instance's primary and secondary nodes' groups are now available as
+ query fields (``pnode.group``, ``pnode.group.uuid``, ``snodes.group``
+ and ``snodes.group.uuid``).
+
+Misc
+~~~~
+
+- Numerous updates to documentation and manpages.
+
+ - :doc:`RAPI <rapi>` documentation now has detailed parameter
+ descriptions.
+ - Some opcode/job results are now also documented, see :doc:`RAPI
+ <rapi>`.
+
+- A lockset's internal lock is now also visible in lock monitor.
+- Log messages from job queue workers now contain information about the
+ opcode they're processing.
+- ``gnt-instance console`` no longer requires the instance lock.
+- A short delay when waiting for job changes reduces the number of LUXI
+ requests significantly.
+- DRBD metadata volumes are overwritten with zeros during disk creation.
+- Out-of-band commands no longer acquire the cluster lock in exclusive
+ mode.
+- ``devel/upload`` now uses correct permissions for directories.

+-------------
+
+*(Released Fri, 5 Aug 2011)*

+ (>= 0.14)
+- Added OS search path to ``gnt-cluster info``

+
+Version 2.4.2
+-------------
+
+*(Released Thu, 12 May 2011)*
+
+Many bug-fixes and a few new small features:
+
+- Fixed a bug related to log opening failures
+- Fixed a bug in instance listing with orphan instances
+- Fixed a bug which prevented resetting the cluster-level node parameter
+ ``oob_program`` to the default
+- Many fixes related to the ``cluster-merge`` tool
+- Fixed a race condition in the lock monitor, which caused failures
+ during (at least) creation of many instances in parallel
+- Improved output for gnt-job info
+- Removed the quiet flag on some ssh calls which prevented debugging
+ failures
+- Improved the N+1 failure messages in cluster verify by actually
+ showing the memory values (needed and available)
+- Increased lock attempt timeouts so that when executing long operations
+ (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
+ too early and thus prevent the use of the 'fair' mechanism
+- Changed instance query data (``gnt-instance info``) to not acquire
+ locks unless needed, thus allowing its use on locked instance if only
+ static information is asked for
+- Improved behaviour with filesystems that do not support rename on an
+ opened file
+- Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
+ kept locks on all nodes during the wipe, which is unneeded
+- Fixed ``gnt-watcher`` handling of errors during hooks execution
+- Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
+ 10GiB) which caused the wipe to fail right at the end in some cases
+- Fixed master IP activation when doing master failover with no-voting
+- Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
+ the master node itself
+- Fixed potential data-loss in under disk full conditions, where Ganeti
+ wouldn't check correctly the return code and would consider
+ partially-written files 'correct'
+- Fixed bug related to multiple VGs and DRBD disk replacing
+- Added new disk parameter ``metavg`` that allows placement of the meta
+ device for DRBD in a different volume group
+- Fixed error handling in the node daemon when the system libc doesn't
+ have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
+- Fixed lock release during replace-disks, which kept cluster-wide locks
+ when doing disk replaces with an iallocator script
+- Added check for missing bridges in cluster verify
+- Handle EPIPE errors while writing to the terminal better, so that
+ piping the output to e.g. ``less`` doesn't cause a backtrace
+- Fixed rare case where a ^C during Luxi calls could have been
+ interpreted as server errors, instead of simply terminating
+- Fixed a race condition in LUGroupAssignNodes (``gnt-group
+ assign-nodes``)
+- Added a few more parameters to the KVM hypervisor, allowing a second
+ CDROM, custom disk type for CDROMs and a floppy image
+- Removed redundant message in instance rename when the name is given
+ already as a FQDN
+- Added option to ``gnt-instance recreate-disks`` to allow creating the
+ disks on new nodes, allowing recreation when the original instance
+ nodes are completely gone
+- Added option when converting disk templates to DRBD to skip waiting
+ for the resync, in order to make the instance available sooner
+- Added two new variables to the OS scripts environment (containing the
+ instance's nodes)
+- Made the root_path and optional parameter for the xen-pvm hypervisor,
+ to allow use of ``pvgrub`` as bootloader
+- Changed the instance memory modifications to only check out-of-memory
+ conditions on memory increases, and turned the secondary node warnings
+ into errors (they can still be overridden via ``--force``)
+- Fixed the handling of a corner case when the Python installation gets
+ corrupted (e.g. a bad disk) while ganeti-noded is running and we try
+ to execute a command that doesn't exist
+- Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
+ node of the instance returned failures during instance shutdown; this
+ adds the option ``--ignore-consistency`` to gnt-instance move
+
+And as usual, various improvements to the error messages, documentation
+and man pages.
+
+
+Version 2.4.1
+-------------
+
+*(Released Wed, 09 Mar 2011)*
+
+Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
+the RAPI users file if run twice (even with ``--dry-run``).
+
+The release fixes that bug (nothing else changed).
+
+
+Version 2.4.0
+-------------
+
+*(Released Mon, 07 Mar 2011)*
+
+Final 2.4.0 release. Just a few small fixes:
+
+- Fixed RAPI node evacuate
+- Fixed the kvm-ifup script
+- Fixed internal error handling for special job cases
+- Updated man page to specify the escaping feature for options
+
+
+Version 2.4.0 rc3
+-----------------
+
+*(Released Mon, 28 Feb 2011)*
+
+A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
+that this feature wiped the disks of the wrong instance, leading to loss
+of data.
+
+Other changes:
+
+- Fixed title of query field containing instance name
+- Expanded the glossary in the documentation
+- Fixed one unittest (internal issue)
+
+
+Version 2.4.0 rc2
+-----------------
+
+*(Released Mon, 21 Feb 2011)*
+
+A number of bug fixes plus just a couple functionality changes.
+
+On the user-visible side, the ``gnt-* list`` command output has changed
+with respect to "special" field states. The current rc1 style of display
+can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
+the default output mode special fields states are displayed as follows:
+
+- Offline resource: ``*``
+- Unavailable/not applicable: ``-``
+- Data missing (RPC failure): ``?``
+- Unknown field: ``??``
+
+Another user-visible change is the addition of ``--force-join`` to
+``gnt-node add``.
+
+As for bug fixes:
+
+- ``tools/cluster-merge`` has seen many fixes and is now enabled again
+- Fixed regression in RAPI/instance reinstall where all parameters were
+ required (instead of optional)
+- Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
+- Fixed iallocator usage (offline nodes were not considered offline)
+- Fixed ``gnt-node list`` with respect to non-vm_capable nodes
+- Fixed hypervisor and OS parameter validation with respect to
+ non-vm_capable nodes
+- Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
+ cosmetic)
+- Fixed ``tools/listrunner`` with respect to agent-based usage
+
+
+Version 2.4.0 rc1
+-----------------
+
+*(Released Fri, 4 Feb 2011)*
+
+Many changes and fixes since the beta1 release. While there were some
+internal changes, the code has been mostly stabilised for the RC
+release.
+
+Note: the dumb allocator was removed in this release, as it was not kept
+up-to-date with the IAllocator protocol changes. It is recommended to
+use the ``hail`` command from the ganeti-htools package.
+
+Note: the 2.4 and up versions of Ganeti are not compatible with the
+0.2.x branch of ganeti-htools. You need to upgrade to
+ganeti-htools-0.3.0 (or later).
+
+Regressions fixed from 2.3
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Fixed the ``gnt-cluster verify-disks`` command
+- Made ``gnt-cluster verify-disks`` work in parallel (as opposed to
+ serially on nodes)
+- Fixed disk adoption breakage
+- Fixed wrong headers in instance listing for field aliases
+
+Other bugs fixed
+~~~~~~~~~~~~~~~~
+
+- Fixed corner case in KVM handling of NICs
+- Fixed many cases of wrong handling of non-vm_capable nodes
+- Fixed a bug where a missing instance symlink was not possible to
+ recreate with any ``gnt-*`` command (now ``gnt-instance
+ activate-disks`` does it)
+- Fixed the volume group name as reported by ``gnt-cluster
+ verify-disks``
+- Increased timeouts for the import-export code, hopefully leading to
+ fewer aborts due network or instance timeouts
+- Fixed bug in ``gnt-node list-storage``
+- Fixed bug where not all daemons were started on cluster
+ initialisation, but only at the first watcher run
+- Fixed many bugs in the OOB implementation
+- Fixed watcher behaviour in presence of instances with offline
+ secondaries
+- Fixed instance list output for instances running on the wrong node
+- a few fixes to the cluster-merge tool, but it still cannot merge
+ multi-node groups (currently it is not recommended to use this tool)
+
+
+Improvements
+~~~~~~~~~~~~
+
+- Improved network configuration for the KVM hypervisor
+- Added e1000 as a supported NIC for Xen-HVM
+- Improved the lvmstrap tool to also be able to use partitions, as
+ opposed to full disks
+- Improved speed of disk wiping (the cluster parameter
+ ``prealloc_wipe_disks``, so that it has a low impact on the total time
+ of instance creations
+- Added documentation for the OS parameters
+- Changed ``gnt-instance deactivate-disks`` so that it can work if the
+ hypervisor is not responding
+- Added display of blacklisted and hidden OS information in
+ ``gnt-cluster info``
+- Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
+ NIC and node parameters, which might create problems with currently
+ invalid (but undetected) configuration files, but prevents validation
+ failures when unrelated parameters are modified
+- Changed cluster initialisation to wait for the master daemon to become
+ available
+- Expanded the RAPI interface:
+
+ - Added config redistribution resource
+ - Added activation/deactivation of instance disks
+ - Added export of console information
+
+- Implemented log file reopening on SIGHUP, which allows using
+ logrotate(8) for the Ganeti log files
+- Added a basic OOB helper script as an example
+
+
+Version 2.4.0 beta1
+-------------------
+
+*(Released Fri, 14 Jan 2011)*
+
+User-visible
+~~~~~~~~~~~~
+
+- Fixed timezone issues when formatting timestamps
+- Added support for node groups, available via ``gnt-group`` and other
+ commands
+- Added out-of-band framework and management, see :doc:`design
+ document <design-oob>`
+- Removed support for roman numbers from ``gnt-node list`` and
+ ``gnt-instance list``.
+- Allowed modification of master network interface via ``gnt-cluster
+ modify --master-netdev``
+- Accept offline secondaries while shutting down instance disks
+- Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors
+- Added support for multiple LVM volume groups
+- Avoid sorting nodes for ``gnt-node list`` if specific nodes are
+ requested
+- Added commands to list available fields:
+
+ - ``gnt-node list-fields``
+ - ``gnt-group list-fields``
+ - ``gnt-instance list-fields``
+
+- Updated documentation and man pages
+
+Integration
+~~~~~~~~~~~
+
+- Moved ``rapi_users`` file into separate directory, now named
+ ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
+ symlink
+- Added new tool for running commands on many machines,
+ ``tools/ganeti-listrunner``
+- Implemented more verbose result in ``OpInstanceConsole`` opcode, also
+ improving the ``gnt-instance console`` output
+- Allowed customisation of disk index separator at ``configure`` time
+- Export node group allocation policy to :doc:`iallocator <iallocator>`
+- Added support for non-partitioned md disks in ``lvmstrap``
+- Added script to gracefully power off KVM instances
+- Split ``utils`` module into smaller parts
+- Changed query operations to return more detailed information, e.g.
+ whether an information is unavailable due to an offline node. To use
+ this new functionality, the LUXI call ``Query`` must be used. Field
+ information is now stored by the master daemon and can be retrieved
+ using ``QueryFields``. Instances, nodes and groups can also be queried
+ using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
+ exposed via RAPI). The following commands make use of this
+ infrastructure change:
+
+ - ``gnt-group list``
+ - ``gnt-group list-fields``
+ - ``gnt-node list``
+ - ``gnt-node list-fields``
+ - ``gnt-instance list``
+ - ``gnt-instance list-fields``
+ - ``gnt-debug locks``

+- New RAPI resources (see :doc:`rapi`):
+
+ - ``/2/modify``
+ - ``/2/groups``
+ - ``/2/groups/[group_name]``
+ - ``/2/groups/[group_name]/assign-nodes``
+ - ``/2/groups/[group_name]/modify``
+ - ``/2/groups/[group_name]/rename``
+ - ``/2/instances/[instance_name]/disk/[disk_index]/grow``
+
+- RAPI changes:
+
+ - Implemented ``no_install`` for instance creation
+ - Implemented OS parameters for instance reinstallation, allowing
+ use of special settings on reinstallation (e.g. for preserving data)
+
+Misc
+~~~~
+
+- Added IPv6 support in import/export

+- Support ``ssh-agent`` again when adding nodes
+- Many additional bugfixes
+
+
+Version 2.2.0 rc0
+-----------------
+
+*(Released Fri, 30 Jul 2010)*
+
+Important change: the internal RPC mechanism between Ganeti nodes has
+changed from using a home-grown http library (based on the Python base
+libraries) to use the PycURL library. This requires that PycURL is
+installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
+against GnuTLS by default. cURL's support for GnuTLS had known issues
+before cURL 7.21.0 and we recommend using the latest cURL release or
+linking against OpenSSL. Most other distributions already link PycURL
+and cURL against OpenSSL. The command::
+
+ python -c 'import pycurl; print pycurl.version'
+
+can be used to determine the libraries PycURL and cURL are linked
+against.
+
+Other significant changes:
+
+- Rewrote much of the internals of the job queue, in order to achieve
+ better parallelism; this decouples job query operations from the job
+ processing, and it should allow much nicer behaviour of the master
+ daemon under load, and it also has uncovered some long-standing bugs
+ related to the job serialisation (now fixed)
+- Added a default iallocator setting to the cluster parameters,
+ eliminating the need to always pass nodes or an iallocator for
+ operations that require selection of new node(s)
+- Added experimental support for the LXC virtualization method
+- Added support for OS parameters, which allows the installation of
+ instances to pass parameter to OS scripts in order to customise the
+ instance
+- Added a hypervisor parameter controlling the migration type (live or
+ non-live), since hypervisors have various levels of reliability; this
+ has renamed the 'live' parameter to 'mode'
+- Added a cluster parameter ``reserved_lvs`` that denotes reserved
+ logical volumes, meaning that cluster verify will ignore them and not
+ flag their presence as errors
+- The watcher will now reset the error count for failed instances after
+ 8 hours, thus allowing self-healing if the problem that caused the
+ instances to be down/fail to start has cleared in the meantime
+- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
+ check for, and warn, if the drbd module parameter ``usermode_helper``
+ is not consistent with the cluster-wide setting; this is needed to
+ make diagnose easier of failed drbd creations
+- Started adding base IPv6 support, but this is not yet
+ enabled/available for use
+- Rename operations (cluster, instance) will now return the new name,
+ which is especially useful if a short name was passed in
+- Added support for instance migration in RAPI
+- Added a tool to pre-configure nodes for the SSH setup, before joining
+ them to the cluster; this will allow in the future a simplified model
+ for node joining (but not yet fully enabled in 2.2); this needs the
+ paramiko python library
+- Fixed handling of name-resolving errors
+- Fixed consistency of job results on the error path
+- Fixed master-failover race condition when executed multiple times in
+ sequence
+- Fixed many bugs related to the job queue (mostly introduced during the
+ 2.2 development cycle, so not all are impacting 2.1)
+- Fixed instance migration with missing disk symlinks
+- Fixed handling of unknown jobs in ``gnt-job archive``
+- And many other small fixes/improvements
+
+Internal changes:
+
+- Enhanced both the unittest and the QA coverage
+- Switched the opcode validation to a generic model, and extended the
+ validation to all opcode parameters
+- Changed more parts of the code that write shell scripts to use the
+ same class for this
+- Switched the master daemon to use the asyncore library for the Luxi
+ server endpoint
+
+
+Version 2.2.0 beta0
+-------------------
+
+*(Released Thu, 17 Jun 2010)*
+
+- Added tool (``move-instance``) and infrastructure to move instances
+ between separate clusters (see :doc:`separate documentation
+ <move-instance>` and :doc:`design document <design-2.2>`)
+- Added per-request RPC timeout
- RAPI now requires a Content-Type header for requests with a body (e.g.
``PUT`` or ``POST``) which must be set to ``application/json`` (see
- RFC2616 (HTTP/1.1), section 7.2.1)
+ :rfc:`2616` (HTTP/1.1), section 7.2.1)
+- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
+ reachable
+- Implemented initial support for running Ganeti daemons as separate
+ users, see configure-time flags ``--with-user-prefix`` and
+ ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
+ time)
+- Instances can be removed after export (``gnt-backup export
+ --remove-instance``)
+- Self-signed certificates generated by Ganeti now use a 2048 bit RSA
+ key (instead of 1024 bit)
+- Added new cluster configuration file for cluster domain secret
+- Import/export now use SSL instead of SSH
+- Added support for showing estimated time when exporting an instance,
+ see the ``ganeti-os-interface(7)`` manpage and look for
+ ``EXP_SIZE_FD``
+
+
+Version 2.1.8
+-------------
+
+*(Released Tue, 16 Nov 2010)*

+
+Bugfixes only:
+ - Don't ignore secondary node silently on non-mirrored disk templates
+ (issue 113)
+ - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)

+
+Bugfixes only:
+ - Add an option to only select some reboot types during qa/burnin.
+ (on some hypervisors consequent reboots are not supported)
+ - Fix infrequent race condition in master failover. Sometimes the old
+ master ip address would be still detected as up for a short time
+ after it was removed, causing failover to fail.
+ - Decrease mlockall warnings when the ctypes module is missing. On
+ Python 2.4 we support running even if no ctypes module is installed,
+ but we were too verbose about this issue.
+ - Fix building on old distributions, on which man doesn't have a
+ --warnings option.
+ - Fix RAPI not to ignore the MAC address on instance creation
+ - Implement the old instance creation format in the RAPI client.
+
+

+ - Improve pylint 0.21 compatibility and warnings with Python 2.6
+ - Fix modify node storage with non-FQDN arguments
+ - Fix RAPI client to authenticate under Python 2.6 when used
+ for more than 5 requests needing authentication
+ - Fix gnt-instance modify -t (storage) giving a wrong error message
+ when converting a non-shutdown drbd instance to plain
+
+
+Version 2.1.4
+-------------
+
+*(Released Fri, 18 Jun 2010)*
+
+A small bugfix release:
+
+ - Fix live migration of KVM instances started with older Ganeti
+ versions which had fewer hypervisor parameters
+ - Fix gnt-instance grow-disk on down instances
+ - Fix an error-reporting bug during instance migration
+ - Better checking of the ``--net`` and ``--disk`` values, to avoid
+ silently ignoring broken ones
+ - Fix an RPC error reporting bug affecting, for example, RAPI client
+ users
+ - Fix bug triggered by different API version os-es on different nodes
+ - Fix a bug in instance startup with custom hvparams: OS level
+ parameters would fail to be applied.
+ - Fix the RAPI client under Python 2.6 (but more work is needed to
+ make it work completely well with OpenSSL)
+ - Fix handling of errors when resolving names from DNS
+
+
+Version 2.1.3
+-------------
+
+*(Released Thu, 3 Jun 2010)*
+
+A medium sized development cycle. Some new features, and some
+fixes/small improvements/cleanups.
+
+Significant features
+~~~~~~~~~~~~~~~~~~~~
+
+The node deamon now tries to mlock itself into memory, unless the
+``--no-mlock`` flag is passed. It also doesn't fail if it can't write
+its logs, and falls back to console logging. This allows emergency
+features such as ``gnt-node powercycle`` to work even in the event of a
+broken node disk (tested offlining the disk hosting the node's
+filesystem and dropping its memory caches; don't try this at home)
+
+KVM: add vhost-net acceleration support. It can be tested with a new
+enough version of the kernel and of qemu-kvm.
+
+KVM: Add instance chrooting feature. If you use privilege dropping for
+your VMs you can also now force them to chroot to an empty directory,
+before starting the emulated guest.
+
+KVM: Add maximum migration bandwith and maximum downtime tweaking
+support (requires a new-enough version of qemu-kvm).
+
+Cluster verify will now warn if the master node doesn't have the master
+ip configured on it.
+
+Add a new (incompatible) instance creation request format to RAPI which
+supports all parameters (previously only a subset was supported, and it
+wasn't possible to extend the old format to accomodate all the new
+features. The old format is still supported, and a client can check for
+this feature, before using it, by checking for its presence in the
+``features`` RAPI resource.
+
+Now with ancient latin support. Try it passing the ``--roman`` option to
+``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
+(requires the python-roman module to be installed, in order to work).
+
+Other changes
+~~~~~~~~~~~~~
+
+As usual many internal code refactorings, documentation updates, and
+such. Among others:
+
+ - Lots of improvements and cleanups to the experimental Remote API
+ (RAPI) client library.
+ - A new unit test suite for the core daemon libraries.
+ - A fix to creating missing directories makes sure the umask is not
+ applied anymore. This enforces the same directory permissions
+ everywhere.
+ - Better handling terminating daemons with ctrl+c (used when running
+ them in debugging mode).
+ - Fix a race condition in live migrating a KVM instance, when stat()
+ on the old proc status file returned EINVAL, which is an unexpected
+ value.
+ - Fixed manpage checking with newer man and utf-8 charachters. But now
+ you need the en_US.UTF-8 locale enabled to build Ganeti from git.
+
+
+Version 2.1.2.1
+---------------
+
+*(Released Fri, 7 May 2010)*
+
+Fix a bug which prevented untagged KVM instances from starting.
+
+
+Version 2.1.2
+-------------
+
+*(Released Fri, 7 May 2010)*
+
+Another release with a long development cycle, during which many
+different features were added.
+
+Significant features
+~~~~~~~~~~~~~~~~~~~~
+
+The KVM hypervisor now can run the individual instances as non-root, to
+reduce the impact of a VM being hijacked due to bugs in the
+hypervisor. It is possible to run all instances as a single (non-root)
+user, to manually specify a user for each instance, or to dynamically
+allocate a user out of a cluster-wide pool to each instance, with the
+guarantee that no two instances will run under the same user ID on any
+given node.
+
+An experimental RAPI client library, that can be used standalone
+(without the other Ganeti libraries), is provided in the source tree as
+``lib/rapi/client.py``. Note this client might change its interface in
+the future, as we iterate on its capabilities.
+
+A new command, ``gnt-cluster renew-crypto`` has been added to easily
+replace the cluster's certificates and crypto keys. This might help in
+case they have been compromised, or have simply expired.
+
+A new disk option for instance creation has been added that allows one
+to "adopt" currently existing logical volumes, with data
+preservation. This should allow easier migration to Ganeti from
+unmanaged (or managed via other software) instances.
+
+Another disk improvement is the possibility to convert between redundant
+(DRBD) and plain (LVM) disk configuration for an instance. This should
+allow better scalability (starting with one node and growing the
+cluster, or shrinking a two-node cluster to one node).
+
+A new feature that could help with automated node failovers has been
+implemented: if a node sees itself as offline (by querying the master
+candidates), it will try to shutdown (hard) all instances and any active
+DRBD devices. This reduces the risk of duplicate instances if an
+external script automatically failovers the instances on such nodes. To
+enable this, the cluster parameter ``maintain_node_health`` should be
+enabled; in the future this option (per the name) will enable other
+automatic maintenance features.
+
+Instance export/import now will reuse the original instance
+specifications for all parameters; that means exporting an instance,
+deleting it and the importing it back should give an almost identical
+instance. Note that the default import behaviour has changed from
+before, where it created only one NIC; now it recreates the original
+number of NICs.
+
+Cluster verify has added a few new checks: SSL certificates validity,
+/etc/hosts consistency across the cluster, etc.
+
+Other changes
+~~~~~~~~~~~~~
+
+As usual, many internal changes were done, documentation fixes,
+etc. Among others:
+
+- Fixed cluster initialization with disabled cluster storage (regression
+ introduced in 2.1.1)
+- File-based storage supports growing the disks
+- Fixed behaviour of node role changes
+- Fixed cluster verify for some corner cases, plus a general rewrite of
+ cluster verify to allow future extension with more checks
+- Fixed log spamming by watcher and node daemon (regression introduced
+ in 2.1.1)
+- Fixed possible validation issues when changing the list of enabled
+ hypervisors
+- Fixed cleanup of /etc/hosts during node removal
+- Fixed RAPI response for invalid methods
+- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
+- Multiple small improvements to the KVM hypervisor (VNC usage, booting
+ from ide disks, etc.)
+- Allow OS changes without re-installation (to record a changed OS
+ outside of Ganeti, or to allow OS renames)
+- Allow instance creation without OS installation (useful for example if
+ the OS will be installed manually, or restored from a backup not in
+ Ganeti format)
+- Implemented option to make cluster ``copyfile`` use the replication
+ network
+- Added list of enabled hypervisors to ssconf (possibly useful for
+ external scripts)
+- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
+ 1.2 clusters
+- A partial form of node re-IP is possible via node readd, which now
+ allows changed node primary IP
+- Command line utilities now show an informational message if the job is
+ waiting for a lock
+- The logs of the master daemon now show the PID/UID/GID of the
+ connected client
Version 2.1.1
-------------
+*(Released Fri, 12 Mar 2010)*
+
