+Version 2.0.3
+ - Added “--ignore-size” to the “gnt-instance activate-disks” command
+ to allow using the pre-2.0.2 behaviour in activation, if any
+ existing instances have mismatched disk sizes in the configuration
+ - Added “gnt-cluster repair-disk-sizes” command to check and update
+ any configuration mismatches for disk sizes
+ - Added “gnt-master cluste-failover --no-voting” to allow master
+ failover to work on two-node clusters
+ - Fixed the ‘--net’ option of “gnt-backup import”, which was unusable
+ - Fixed detection of OS script errors in “gnt-backup export”
+ - Fixed exit code of “gnt-backup export”
+
+Version 2.0.2
+ - Added experimental support for stripped logical volumes; this should
+ enhance performance but comes with a higher complexity in the block
+ device handling; stripping is only enabled when passing
+ --with-lvm-stripecount=N to configure, but codepaths are affected
+ even in the non-stripped mode
+ - Improved resiliency against transient failures at the end of DRBD
+ resyncs, and in general of DRBD resync checks
+ - Fixed a couple of issues with exports and snapshot errors
+ - Fixed a couple of issues in instance listing
+ - Added display of the disk size in “gnt-instance info”
+ - Fixed checking for valid OSes in instance creation
+ - Fixed handling of the ‘vcpus’ parameter in instance listing and in
+ general of invalid parameters
+ - Fixed http server library, and thus RAPI, to handle invalid
+ username/password combinations correctly; this means that now they
+ report unauthorized for queries too, not only for modifications,
+ allowing earlier detect of configuration problems
+ - Added a new ‘role’ node list field, equivalent to the master/master
+ candidate/drained/offline flags combinations
+ - Fixed cluster modify and changes of candidate pool size
+ - Fixed cluster verify error messages for wrong files on regular nodes
+ - Fixed a couple of issues with node demotion from master candidate
+ role
+ - Fixed node readd issues
+ - Added non-interactive mode for “ganeti-masterd --no-voting” startup
+ - Added a new ‘--no-voting’ option for masterfailover to fix failover
+ on two-nodes clusters when the former master node is unreachable
+ - Added instance reinstall over RAPI
+
+Version 2.0.1
+ - added -H/-B startup parameters to gnt-instance, which will allow
+ re-adding the start in single-user option (regression from 1.2)
+ - the watcher writes the instance status to a file, to allow
+ monitoring to report the instance status (from the master) based on
+ cached results of the watcher's queries; while this can get stale if
+ the watcher is being locked due to other work on the cluster, this
+ is still an improvement
+ - the watcher now also restarts the node daemon and the rapi daemon if
+ they died
+ - fixed the watcher to handle full and drained queue cases
+ - hooks export more instance data in the environment, which helps if
+ hook scripts need to take action based on the instance's properties
+ (no longer need to query back into ganeti)
+ - instance failovers when the instance is stopped do not check for
+ free RAM, so that failing over a stopped instance is possible in low
+ memory situations
+ - rapi uses queries for tags instead of jobs (for less job traffic),
+ and for cluster tags it won't talk to masterd at all but read them
+ from ssconf
+ - a couple of error handling fixes in RAPI
+ - drbd handling: improved the error handling of inconsistent disks
+ after resync to reduce the frequency of "there are some degraded
+ disks for this instance" message
+ - fixed a bug in live migration when DRBD doesn't want to reconnect
+ (the error handling path called a wrong function name)
+
+Version 2.0.0 final
+ - no changes from rc5
+
+Version 2.0 release candidate 5
+ - fix a couple of bugs (validation, argument checks)
+ - fix gnt-cluster getmaster on non-master nodes (regression)
+ - some small improvements to RAPI and IAllocator
+ - make watcher automatically start the master daemon if down
+
+Version 2.0 release candidate 4
+ - change the OS list to not require locks; this helps with big
+ clusters
+ - fix gnt-cluster verify and gnt-cluster verify-disks when the volume
+ group is broken
+ - “gnt-instance info”, without any arguments, doesn't run for all
+ instances anymore; either pass ‘--all’ or pass the desired
+ instances; this helps against mistakes on big clusters where listing
+ the information for all instances takes a long time
+ - miscellaneous doc and man pages fixes
+
+Version 2.0 release candidate 3
+ - Change the internal locking model of some gnt-node commands, in
+ order to reduce contention (and blocking of master daemon) when
+ batching many creation/reinstall jobs
+ - Fixes to Xen soft reboot
+ - No longer build documentation at 'make' time, instead distribute it
+ in the archive, in order to reduce the need for the whole
+ docbook/rst toolchains
+
+Version 2.0 release candidate 2
+ - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to
+ 2.0
+ - Fix watcher startup sequence, improves the behaviour of busy
+ clusters
+ - Some other fixes in cluster verify, replace-disks, gnt-instance add,
+ gnt-cluster queue, KVM VNC bind address and other places
+ - Some documentation fixes and updates
+
+Version 2.0 release candidate 1
+ - More documentation updates, now all docs should be more-or-less
+ up-to-date
+ - A couple of small fixes (mixed hypervisor clusters, offline nodes,
+ etc.)
+ - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen
+ PVM and KVM)
+ - Fix an issue related to $libdir/run/ganeti and cluster creation
+
+Version 2.0 beta 2
+ - Xen PVM and KVM have switched the default value for the instance
+ root disk to the first partition on the first drive, instead of the
+ whole drive; this means that the OS installation scripts must be
+ changed accordingly
+ - Man pages have been updated
+ - RAPI has been switched by default to HTTPS, and the exported
+ functions should all work correctly
+ - RAPI v1 has been removed
+ - Many improvements to the KVM hypervisor
+ - Block device errors are now better reported
+ - Many other bugfixes and small improvements
+
+Version 2.0 beta 1
+ - Version 2 is a general rewrite of the code and therefore the
+ differences are too many to list, see the design document for 2.0 in
+ the doc/ subdirectory for more details
+ - In this beta version there is not yet a migration path from 1.2
+ (there will be one in the final 2.0 release)
+ - A few significant changes are:
+ - all commands are executed by a daemon (ganeti-masterd) and the
+ various gnt-* commands are just front-ends to it
+ - all the commands are entered into, and executed from a job queue,
+ see gnt-job(8)
+ - the RAPI daemon supports read-write operations, secured by basic
+ HTTP authentication on top of HTTPS
+ - DRBD version 0.7 support has been removed, DRBD 8 is the only
+ supported version (when migrating from Ganeti 1.2 to 2.0, you need
+ to migrate to DRBD 8 first while still running Ganeti 1.2)
+ - DRBD devices are using statically allocated minor numbers, which
+ will be assigned to existing instances during the migration
+ process
+ - there is support for both Xen PVM and Xen HVM instances running on
+ the same cluster
+ - KVM virtualization is supported too
+ - file-based storage has been implemented, which means that it is
+ possible to run the cluster without LVM and DRBD storage, for
+ example using a shared filesystem exported from shared storage
+ (and still have live migration)
+
+Version 1.2.7
+ - Change the default reboot type in gnt-instance reboot to "hard"
+ - Reuse the old instance mac address by default on instance import,
+ if the instance name is the same.
+ - Handle situations in which the node info rpc returns incomplete results
+ (issue 46)
+ - Add checks for tcp/udp ports collisions in gnt-cluster verify
+ - Improved version of batcher:
+ - state file support
+ - instance mac address support
+ - support for HVM clusters/instances
+ - Add an option to show the number of cpu sockets and nodes in gnt-node list
+ - Support OSes that handle more than one version of the OS api
+ (but do not change the current API in any other way)
+ - Fix gnt-node migrate
+ - gnt-debug man page
+ - Fixes various more typos&small issues
+ - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
+
+Version 1.2.6
+ - new --hvm-nic-type and --hvm-disk-type flags to control the type of disk
+ exported to fully virtualized instances.
+ - provide access to the serial console of HVM instances
+ - instance auto_balance flag, set by default. If turned off it will avoid
+ warnings on cluster verify if there is not enough memory to fail over an
+ instance. in the future it will prevent automatically failing it over when
+ we will support that.
+ - batcher tool for instance creation, see /tools/README.batcher
+ - gnt-instance reinstall --select-os to interactively select a new operating
+ system when reinstalling an instance.
+ - when changing the memory amount on instance modify a check has been added
+ that the instance will be able to start. also warnings are emitted if the
+ instance will not be able to fail over, if auto_balance is true.
+ - documentation fixes
+ - sync fields between instance list/modify/add/import
+ - fix a race condition in drbd when the sync speed was set after giving the
+ device a remote peer.
+
+Version 1.2.5
+ - note: the allowed size and number of tags per object were reduced
+ - fix a bug in “gnt-cluster verify” with inconsistent volume groups
+ - fixed twisted 8.x compatibility
+ - fixed gnt-instance replace-disks with iallocator
+ - add TCP keepalives on twisted connections to detect restarted nodes
+ - disk increase support, see “gnt-instance grow-disk”
+ - implement bulk node/instance query for RAPI
+ - add tags in node/instance listing (optional)
+ - experimental migration (and live migration) support, read the man
+ page for “gnt-instance migrate”
+ - the ganeti-watcher logs are now timestamped, and the watcher also
+ has some small improvements in handling its state file
+
+Version 1.2.4
+ - Experimental readonly, REST-based remote API implementation; automatically
+ started on master node, TCP port 5080, if enabled by --enable-rapi
+ parameter to configure script.
+ - Instance allocator support. Add and import instance accept a --iallocator
+ parameter, and call that instance allocator to decide which node to use for
+ the instance. The iallocator document describes what's expected from an
+ allocator script.
+ - gnt-cluster verify N+1 memory redundancy checks: Unless passed the
+ --no-nplus1-mem option gnt-cluster verify now checks that if a node is lost
+ there is still enough memory to fail over the instances that reside on it.
+ - gnt-cluster verify hooks: it is now possible to add post-hooks to
+ gnt-cluster verify, to check for site-specific compliance. All the hooks
+ will run, and their output, if any, will be displayed. Any failing hook
+ will make the verification return an error value.
+ - gnt-cluster verify now checks that its peers are reachable on the primary
+ and secondary interfaces
+ - gnt-node add now supports the --readd option, to readd a node that is still
+ declared as part of the cluster and has failed.
+ - gnt-* list commands now accept a new -o +field way of specifying output
+ fields, that just adds the chosen fields to the default ones.
+ - gnt-backup now has a new "remove" command to delete an existing export from
+ the filesystem.
+ - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have
+ been added. Using them you can enable/disable acpi and pae support, and
+ specify a path for a cd image to be exported to the instance. These
+ parameters as the name suggest only work on HVM clusters.
+ - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE
+ support will be set to the previously hardcoded values, but the (previously
+ hardcoded) path to the CDROM ISO image will be unset and if required, needs
+ to be set manually with gnt-instance modify after the upgrade..
+ - The address to which an instance's VNC console is bound is now selectable
+ per-instance, rather than being cluster wide. Of course this only applies
+ to instances controlled via VNC, so currently just applies to HVM clusters.
+
+Version 1.2.3
+ - more tweaks to the disk activation code (especially helpful for DRBD)
+ - change the default ‘gnt-instance list’ output format, now there is
+ one combined status field (see the manpage for the exact values this
+ field will have)
+ - some more fixes for the mac export to hooks change
+ - make Ganeti not break with DRBD 8.2.x (which changed the version
+ format in /proc/drbd) (issue 24)
+ - add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk
+ template, allowing migration from DRBD0.7+MD to DRBD8
+
Version 1.2.2
- fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM
support (issue 23)
