+Version 2.5.0 beta3
+-------------------
+
+*(Released Wed, 31 Aug 2011)*
+
+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.
+
+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 *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.
+
+- 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.
+
+
+Version 2.5.0 beta2
+-------------------
+
+*(Released Mon, 22 Aug 2011)*

+
+Version 2.5.0 beta1
+-------------------
+
+*(Released Fri, 12 Aug 2011)*

+This was the first beta release of the 2.5 series.
+
+

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

+
+- Fixed argument order in ``ReserveLV`` and ``ReserveMAC`` which caused
+ issues when you tried to add an instance with two MAC addresses in one
+ request
+- KVM: fixed per-instance stored UID value
+- KVM: configure bridged NICs at migration start
+- KVM: Fix a bug where instance will not start with never KVM versions
+ (>= 0.14)
+- Added OS search path to ``gnt-cluster info``
+- Fixed an issue with ``file_storage_dir`` where you were forced to
+ provide an absolute path, but the documentation states it is a
+ relative path, the documentation was right
+- Added a new parameter to instance stop/start called ``--no-remember``
+ that will make the state change to not be remembered
+- Implemented ``no_remember`` at RAPI level
+- Improved the documentation
+- Node evacuation: don't call IAllocator if node is already empty
+- Fixed bug in DRBD8 replace disks on current nodes
+- Fixed bug in recreate-disks for DRBD instances

+
+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``
+
+Remote API
+~~~~~~~~~~
+
+- 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

+- 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 beta 0
+--------------------
+
+*(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
+ :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)*
+
+Some more bugfixes. Unless critical bugs occur, this will be the last
+2.1 release:
+
+- Fix case of MAC special-values
+- Fix mac checker regex
+- backend: Fix typo causing "out of range" error
+- Add missing --units in gnt-instance list man page
+
+
+Version 2.1.7
+-------------
+
+*(Released Tue, 24 Aug 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)
+ - Fix usb_mouse parameter breaking with vnc_console (issue 109)
+ - Properly document the usb_mouse parameter
+ - Fix path in ganeti-rapi(8) (issue 116)
+ - Adjust error message when the ganeti user's .ssh directory is
+ missing
+ - Add same-node-check when changing the disk template to drbd
+
+
+Version 2.1.6
+-------------
+
+*(Released Fri, 16 Jul 2010)*
+
+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.
+
+
+Version 2.1.5
+-------------
+
+*(Released Thu, 01 Jul 2010)*
+
+A small bugfix release:
+ - Fix disk adoption: broken by strict --disk option checking in 2.1.4
+ - Fix batch-create: broken in the whole 2.1 series due to a lookup on
+ a non-existing option
+ - Fix instance create: the --force-variant option was ignored
+ - 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
---------------
directory (e.g. read-only file-system where we can't open the files
read-write, etc.)
- Fixed the behaviour of gnt-node modify for master candidate demotion;
- now it either aborts cleanly or, if given the new “auto_promote”
+ now it either aborts cleanly or, if given the new "auto_promote"
parameter, will automatically promote other nodes as needed
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
completely prevent Ganeti from working
New features
