-Version 2.7.0 beta1
+Version 2.8.0 beta1
-------------------
*(unreleased)*
+- The minimum Python version needed to run Ganeti is now 2.6.
+- The :doc:`Remote API <rapi>` daemon now supports a command line flag
+ to always require authentication, ``--require-authentication``. It can
+ be specified in ``$sysconfdir/default/ganeti``.
+- A new cluster attribute 'enabled_storage_types' is introduced. It will
+ be used to manage the storage types to be used by instances in the cluster.
+ Initially, it will be set to a list that includes lvm, file and sharedfile
+ if those are enabled. Additionally, it will include all storage types that
+ are currently used by instances. The order of storage types will be based
+ on Ganeti's history of supporting them. In the future, the first entry of
+ the list will be used as a default storage type on instance creation.

- ``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 now to be listed in
- ``$sysconfdir/ganeti/file-storage-paths``. ``cfgupgrade`` will write
- the file automatically based on old configuration values, but it can
- not distribute it across all nodes and the file contents should be
+- Parent directories for file storage need to be listed in
+ ``$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
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(8)` has been slightly changed: now empty
- lines and comment lines are ignored for better readability.
+ :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``.
+- 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.
+- 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.
+- 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.
+- The functionality for allocating multiple instances at once has been
+ overhauled and is now also available through :doc:`RAPI <rapi>`.
+- Man pages can now be included when the documentation is built, in
+ which case the output is in ``doc/man-html``. The configure-time
+ option is ``--enable-manpages-in-doc``. Sphinx 1.0 or higher is
+ required.
+- A new htool called ``hroller`` helps scheduling parallel shutdown of
+ nodes on clusters where all instances are shut down, but without ever
+ rebooting both primary and secondary node for an instance at the same
+ time.
+- 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 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)`.
+- New ``exclusive-storage`` node parameter added. 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.
+- 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)`.
+- Instance renames of LVM-based instances will now update the LV tags
+ (which can be used to recover the instance-to-LV mapping in case of
+ emergencies)
+- ``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
+
+
+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.
