9 A small bugfix release:
10 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
11 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
13 - Fix instance create: the --force-variant option was ignored
14 - Improve pylint 0.21 compatibility and warnings with Python 2.6
15 - Fix modify node storage with non-FQDN arguments
16 - Fix RAPI client to authenticate under Python 2.6 when used

18 - Fix gnt-instance modify -t (storage) giving a wrong error message
19 when converting a non-shutdown drbd instance to plain
24 *(Released Fri, 18 Jun 2010)*
26 A small bugfix release:
28 - Fix live migration of KVM instances started with older Ganeti
29 versions which had fewer hypervisor parameters
30 - Fix gnt-instance grow-disk on down instances
31 - Fix an error-reporting bug during instance migration

33 silently ignoring broken ones
34 - Fix an RPC error reporting bug affecting, for example, RAPI client
36 - Fix bug triggered by different API version os-es on different nodes
37 - Fix a bug in instance startup with custom hvparams: OS level

39 - Fix the RAPI client under Python 2.6 (but more work is needed to
40 make it work completely well with OpenSSL)
41 - Fix handling of errors when resolving names from DNS
46 *(Released Thu, 3 Jun 2010)*
48 A medium sized development cycle. Some new features, and some
49 fixes/small improvements/cleanups.
54 The node deamon now tries to mlock itself into memory, unless the
55 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
56 its logs, and falls back to console logging. This allows emergency
57 features such as ``gnt-node powercycle`` to work even in the event of a
58 broken node disk (tested offlining the disk hosting the node's
59 filesystem and dropping its memory caches; don't try this at home)
61 KVM: add vhost-net acceleration support. It can be tested with a new
62 enough version of the kernel and of qemu-kvm.
64 KVM: Add instance chrooting feature. If you use privilege dropping for
65 your VMs you can also now force them to chroot to an empty directory,
66 before starting the emulated guest.
68 KVM: Add maximum migration bandwith and maximum downtime tweaking
69 support (requires a new-enough version of qemu-kvm).
71 Cluster verify will now warn if the master node doesn't have the master
74 Add a new (incompatible) instance creation request format to RAPI which
75 supports all parameters (previously only a subset was supported, and it
76 wasn't possible to extend the old format to accomodate all the new
77 features. The old format is still supported, and a client can check for
78 this feature, before using it, by checking for its presence in the
79 ``features`` RAPI resource.
81 Now with ancient latin support. Try it passing the ``--roman`` option to
82 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
83 (requires the python-roman module to be installed, in order to work).
88 As usual many internal code refactorings, documentation updates, and
91 - Lots of improvements and cleanups to the experimental Remote API
92 (RAPI) client library.
93 - A new unit test suite for the core daemon libraries.
94 - A fix to creating missing directories makes sure the umask is not
95 applied anymore. This enforces the same directory permissions
97 - Better handling terminating daemons with ctrl+c (used when running
98 them in debugging mode).
99 - Fix a race condition in live migrating a KVM instance, when stat()
100 on the old proc status file returned EINVAL, which is an unexpected
102 - Fixed manpage checking with newer man and utf-8 charachters. But now
103 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
109 *(Released Fri, 7 May 2010)*
111 Fix a bug which prevented untagged KVM instances from starting.
117 *(Released Fri, 7 May 2010)*
119 Another release with a long development cycle, during which many
120 different features were added.
125 The KVM hypervisor now can run the individual instances as non-root, to
126 reduce the impact of a VM being hijacked due to bugs in the
127 hypervisor. It is possible to run all instances as a single (non-root)
128 user, to manually specify a user for each instance, or to dynamically
129 allocate a user out of a cluster-wide pool to each instance, with the
130 guarantee that no two instances will run under the same user ID on any
133 An experimental RAPI client library, that can be used standalone
134 (without the other Ganeti libraries), is provided in the source tree as
135 ``lib/rapi/client.py``. Note this client might change its interface in
136 the future, as we iterate on its capabilities.
138 A new command, ``gnt-cluster renew-crypto`` has been added to easily
139 replace the cluster's certificates and crypto keys. This might help in
140 case they have been compromised, or have simply expired.
142 A new disk option for instance creation has been added that allows one
143 to "adopt" currently existing logical volumes, with data
144 preservation. This should allow easier migration to Ganeti from
145 unmanaged (or managed via other software) instances.
147 Another disk improvement is the possibility to convert between redundant
148 (DRBD) and plain (LVM) disk configuration for an instance. This should
149 allow better scalability (starting with one node and growing the
150 cluster, or shrinking a two-node cluster to one node).
152 A new feature that could help with automated node failovers has been
153 implemented: if a node sees itself as offline (by querying the master
154 candidates), it will try to shutdown (hard) all instances and any active
155 DRBD devices. This reduces the risk of duplicate instances if an
156 external script automatically failovers the instances on such nodes. To
157 enable this, the cluster parameter ``maintain_node_health`` should be
158 enabled; in the future this option (per the name) will enable other
159 automatic maintenance features.
161 Instance export/import now will reuse the original instance
162 specifications for all parameters; that means exporting an instance,
163 deleting it and the importing it back should give an almost identical
164 instance. Note that the default import behaviour has changed from
165 before, where it created only one NIC; now it recreates the original
168 Cluster verify has added a few new checks: SSL certificates validity,
169 /etc/hosts consistency across the cluster, etc.
174 As usual, many internal changes were done, documentation fixes,
177 - Fixed cluster initialization with disabled cluster storage (regression
179 - File-based storage supports growing the disks
180 - Fixed behaviour of node role changes
181 - Fixed cluster verify for some corner cases, plus a general rewrite of
182 cluster verify to allow future extension with more checks
183 - Fixed log spamming by watcher and node daemon (regression introduced
185 - Fixed possible validation issues when changing the list of enabled
187 - Fixed cleanup of /etc/hosts during node removal
188 - Fixed RAPI response for invalid methods
189 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
190 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
191 from ide disks, etc.)
192 - Allow OS changes without re-installation (to record a changed OS
193 outside of Ganeti, or to allow OS renames)
194 - Allow instance creation without OS installation (useful for example if
195 the OS will be installed manually, or restored from a backup not in
197 - Implemented option to make cluster ``copyfile`` use the replication
199 - Added list of enabled hypervisors to ssconf (possibly useful for
201 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
203 - A partial form of node re-IP is possible via node readd, which now
204 allows changed node primary IP
205 - Command line utilities now show an informational message if the job is
207 - The logs of the master daemon now show the PID/UID/GID of the
214 *(Released Fri, 12 Mar 2010)*
216 During the 2.1.0 long release candidate cycle, a lot of improvements and
217 changes have accumulated with were released later as 2.1.1.
222 The node evacuate command (``gnt-node evacuate``) was significantly
223 rewritten, and as such the IAllocator protocol was changed - a new
224 request type has been added. This unfortunate change during a stable
225 series is designed to improve performance of node evacuations; on
226 clusters with more than about five nodes and which are well-balanced,
227 evacuation should proceed in parallel for all instances of the node
228 being evacuated. As such, any existing IAllocator scripts need to be
229 updated, otherwise the above command will fail due to the unknown
230 request. The provided "dumb" allocator has not been updated; but the
231 ganeti-htools package supports the new protocol since version 0.2.4.
233 Another important change is increased validation of node and instance
234 names. This might create problems in special cases, if invalid host
235 names are being used.
237 Also, a new layer of hypervisor parameters has been added, that sits at
238 OS level between the cluster defaults and the instance ones. This allows
239 customisation of virtualization parameters depending on the installed
240 OS. For example instances with OS 'X' may have a different KVM kernel
241 (or any other parameter) than the cluster defaults. This is intended to
242 help managing a multiple OSes on the same cluster, without manual
243 modification of each instance's parameters.
245 A tool for merging clusters, ``cluster-merge``, has been added in the
251 - Improved the int/float conversions that should make the code more
252 robust in face of errors from the node daemons
253 - Fixed the remove node code in case of internal configuration errors
254 - Fixed the node daemon behaviour in face of inconsistent queue
255 directory (e.g. read-only file-system where we can't open the files
257 - Fixed the behaviour of gnt-node modify for master candidate demotion;
258 now it either aborts cleanly or, if given the new “auto_promote”
259 parameter, will automatically promote other nodes as needed
260 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
261 completely prevent Ganeti from working
262 - Fixed bug for instance export when not all disks were successfully
264 - Fixed behaviour of node add when the new node is slow in starting up
266 - Fixed handling of signals in the LUXI client, which should improve
267 behaviour of command-line scripts
268 - Added checks for invalid node/instance names in the configuration (now
269 flagged during cluster verify)
270 - Fixed watcher behaviour for disk activation errors
271 - Fixed two potentially endless loops in http library, which led to the
272 RAPI daemon hanging and consuming 100% CPU in some cases
273 - Fixed bug in RAPI daemon related to hashed passwords
274 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
276 - Enhanced compatibility with non-Debian OSes, but not using absolute
277 path in some commands and allowing customisation of the ssh
278 configuration directory
279 - Fixed possible future issue with new Python versions by abiding to the
280 proper use of ``__slots__`` attribute on classes
281 - Added checks that should prevent directory traversal attacks
282 - Many documentation fixes based on feedback from users
287 - Added an “early_release” more for instance replace disks and node
288 evacuate, where we release locks earlier and thus allow higher
289 parallelism within the cluster
290 - Added watcher hooks, intended to allow the watcher to restart other
291 daemons (e.g. from the ganeti-nbma project), but they can be used of
292 course for any other purpose
293 - Added a compile-time disable for DRBD barriers, to increase
294 performance if the administrator trusts the power supply or the
295 storage system to not lose writes
296 - Added the option of using syslog for logging instead of, or in
297 addition to, Ganeti's own log files
298 - Removed boot restriction for paravirtual NICs for KVM, recent versions
299 can indeed boot from a paravirtual NIC
300 - Added a generic debug level for many operations; while this is not
301 used widely yet, it allows one to pass the debug value all the way to
303 - Enhanced the hooks environment for instance moves (failovers,
304 migrations) where the primary/secondary nodes changed during the
305 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
306 - Enhanced data validations for many user-supplied values; one important
307 item is the restrictions imposed on instance and node names, which
308 might reject some (invalid) host names
309 - Add a configure-time option to disable file-based storage, if it's not
310 needed; this allows greater security separation between the master
311 node and the other nodes from the point of view of the inter-node RPC
313 - Added user notification in interactive tools if job is waiting in the
314 job queue or trying to acquire locks
315 - Added log messages when a job is waiting for locks
316 - Added filtering by node tags in instance operations which admit
317 multiple instances (start, stop, reboot, reinstall)
318 - Added a new tool for cluster mergers, ``cluster-merge``
319 - Parameters from command line which are of the form ``a=b,c=d`` can now
320 use backslash escapes to pass in values which contain commas,
321 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
323 - For KVM, the instance name is the first parameter passed to KVM, so
324 that it's more visible in the process list
330 *(Released Tue, 2 Mar 2010)*
332 Ganeti 2.1 brings many improvements with it. Major changes:
334 - Added infrastructure to ease automated disk repairs
335 - Added new daemon to export configuration data in a cheaper way than
337 - Instance NICs can now be routed instead of being associated with a
339 - Improved job locking logic to reduce impact of jobs acquiring multiple
340 locks waiting for other long-running jobs
342 In-depth implementation details can be found in the Ganeti 2.1 design
348 - Added chroot hypervisor
349 - Added more options to xen-hvm hypervisor (``kernel_path`` and
351 - Added more options to xen-pvm hypervisor (``use_bootloader``,
352 ``bootloader_path`` and ``bootloader_args``)
353 - Added the ``use_localtime`` option for the xen-hvm and kvm
354 hypervisors, and the default value for this has changed to false (in
355 2.0 xen-hvm always enabled it)
356 - Added luxi call to submit multiple jobs in one go
357 - Added cluster initialization option to not modify ``/etc/hosts``
359 - Added network interface parameters
360 - Added dry run mode to some LUs
361 - Added RAPI resources:
363 - ``/2/instances/[instance_name]/info``
364 - ``/2/instances/[instance_name]/replace-disks``
365 - ``/2/nodes/[node_name]/evacuate``
366 - ``/2/nodes/[node_name]/migrate``
367 - ``/2/nodes/[node_name]/role``
368 - ``/2/nodes/[node_name]/storage``
369 - ``/2/nodes/[node_name]/storage/modify``
370 - ``/2/nodes/[node_name]/storage/repair``
372 - Added OpCodes to evacuate or migrate all instances on a node
373 - Added new command to list storage elements on nodes (``gnt-node
374 list-storage``) and modify them (``gnt-node modify-storage``)
375 - Added new ssconf files with master candidate IP address
376 (``ssconf_master_candidates_ips``), node primary IP address
377 (``ssconf_node_primary_ips``) and node secondary IP address
378 (``ssconf_node_secondary_ips``)
379 - Added ``ganeti-confd`` and a client library to query the Ganeti
380 configuration via UDP
381 - Added ability to run hooks after cluster initialization and before
383 - Added automatic mode for disk replace (``gnt-instance replace-disks
385 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
386 after catastrophic data-loss
387 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume

390 - Added ``gnt-cluster watcher`` command to control watcher
391 - Added ``gnt-node powercycle`` command to powercycle nodes
392 - Added new job status field ``lock_status``
393 - Added parseable error codes to cluster verification (``gnt-cluster
394 verify --error-codes``) and made output less verbose (use
395 ``--verbose`` to restore previous behaviour)
396 - Added UUIDs to the main config entities (cluster, nodes, instances)
397 - Added support for OS variants
398 - Added support for hashed passwords in the Ganeti remote API users file
400 - Added option to specify maximum timeout on instance shutdown
401 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
402 - Added new helper script to start and stop Ganeti daemons
403 (``daemon-util``), with the intent to reduce the work necessary to
404 adjust Ganeti for non-Debian distributions and to start/stop daemons
406 - Added more unittests
407 - Fixed critical bug in ganeti-masterd startup
408 - Removed the configure-time ``kvm-migration-port`` parameter, this is
409 now customisable at the cluster level for both the KVM and Xen
410 hypervisors using the new ``migration_port`` parameter
411 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
412 reinstalling an instance
413 - Allowed ``@`` in tag names

434 - Fix a string formatting bug
435 - Improve safety of the code in some error paths
436 - Improve data validation in the master of values returned from nodes
442 *(Released Thu, 17 Dec 2009)*
444 - Fix security issue due to missing validation of iallocator names; this
445 allows local and remote execution of arbitrary executables
446 - Fix failure of gnt-node list during instance removal
447 - Ship the RAPI documentation in the archive
453 *(Released Wed, 30 Sep 2009)*
455 - Fixed many wrong messages
456 - Fixed a few bugs related to the locking library
457 - Fixed MAC checking at instance creation time
458 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
459 - Fixed a few issues related to signal handling in both daemons and
461 - Fixed the example startup script provided
462 - Fixed insserv dependencies in the example startup script (patch from
464 - Fixed handling of drained nodes in the iallocator framework
465 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
467 - Fixed error related to invalid job IDs in job polling
468 - Fixed job/opcode persistence on unclean master shutdown
469 - Fixed handling of partial job processing after unclean master
471 - Fixed error reporting from LUs, previously all errors were converted
472 into execution errors
473 - Fixed error reporting from burnin
474 - Decreased significantly the memory usage of the job queue
475 - Optimised slightly multi-job submission
476 - Optimised slightly opcode loading
477 - Backported the multi-job submit framework from the development
478 branch; multi-instance start and stop should be faster
479 - Added script to clean archived jobs after 21 days; this will reduce
480 the size of the queue directory
481 - Added some extra checks in disk size tracking
482 - Added an example ethers hook script
483 - Added a cluster parameter that prevents Ganeti from modifying of
485 - Added more node information to RAPI responses
486 - Added a ``gnt-job watch`` command that allows following the ouput of a
488 - Added a bind-address option to ganeti-rapi
489 - Added more checks to the configuration verify
490 - Enhanced the burnin script such that some operations can be retried
492 - Converted instance reinstall to multi-instance model
498 *(Released Fri, 7 Aug 2009)*
500 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
501 to allow using the pre-2.0.2 behaviour in activation, if any existing
502 instances have mismatched disk sizes in the configuration
503 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
504 any configuration mismatches for disk sizes
505 - Added ``gnt-master cluste-failover --no-voting`` to allow master
506 failover to work on two-node clusters
507 - Fixed the ``--net`` option of ``gnt-backup import``, which was
509 - Fixed detection of OS script errors in ``gnt-backup export``
510 - Fixed exit code of ``gnt-backup export``
516 *(Released Fri, 17 Jul 2009)*
518 - Added experimental support for stripped logical volumes; this should
519 enhance performance but comes with a higher complexity in the block
520 device handling; stripping is only enabled when passing
521 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
522 affected even in the non-stripped mode
523 - Improved resiliency against transient failures at the end of DRBD
524 resyncs, and in general of DRBD resync checks
525 - Fixed a couple of issues with exports and snapshot errors
526 - Fixed a couple of issues in instance listing
527 - Added display of the disk size in ``gnt-instance info``
528 - Fixed checking for valid OSes in instance creation
529 - Fixed handling of the "vcpus" parameter in instance listing and in
530 general of invalid parameters
531 - Fixed http server library, and thus RAPI, to handle invalid
532 username/password combinations correctly; this means that now they
533 report unauthorized for queries too, not only for modifications,
534 allowing earlier detect of configuration problems
535 - Added a new "role" node list field, equivalent to the master/master
536 candidate/drained/offline flags combinations
537 - Fixed cluster modify and changes of candidate pool size
538 - Fixed cluster verify error messages for wrong files on regular nodes
539 - Fixed a couple of issues with node demotion from master candidate role
540 - Fixed node readd issues
541 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
542 - Added a new ``--no-voting`` option for masterfailover to fix failover
543 on two-nodes clusters when the former master node is unreachable
544 - Added instance reinstall over RAPI
550 *(Released Tue, 16 Jun 2009)*
552 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
553 allow re-adding the start in single-user option (regression from 1.2)
554 - the watcher writes the instance status to a file, to allow monitoring
555 to report the instance status (from the master) based on cached
556 results of the watcher's queries; while this can get stale if the
557 watcher is being locked due to other work on the cluster, this is
559 - the watcher now also restarts the node daemon and the rapi daemon if
561 - fixed the watcher to handle full and drained queue cases
562 - hooks export more instance data in the environment, which helps if
563 hook scripts need to take action based on the instance's properties
564 (no longer need to query back into ganeti)
565 - instance failovers when the instance is stopped do not check for free
566 RAM, so that failing over a stopped instance is possible in low memory
568 - rapi uses queries for tags instead of jobs (for less job traffic), and
569 for cluster tags it won't talk to masterd at all but read them from
571 - a couple of error handling fixes in RAPI
572 - drbd handling: improved the error handling of inconsistent disks after
573 resync to reduce the frequency of "there are some degraded disks for
574 this instance" messages
575 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
576 error handling path called a wrong function name)
582 *(Released Wed, 27 May 2009)*
584 - no changes from rc5
587 Version 2.0 release candidate 5
588 -------------------------------
590 *(Released Wed, 20 May 2009)*
592 - fix a couple of bugs (validation, argument checks)
593 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)

598 Version 2.0 release candidate 4
599 -------------------------------
601 *(Released Mon, 27 Apr 2009)*
603 - change the OS list to not require locks; this helps with big clusters
604 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
605 volume group is broken
606 - ``gnt-instance info``, without any arguments, doesn't run for all
607 instances anymore; either pass ``--all`` or pass the desired
608 instances; this helps against mistakes on big clusters where listing
609 the information for all instances takes a long time
610 - miscellaneous doc and man pages fixes
613 Version 2.0 release candidate 3
614 -------------------------------
616 *(Released Wed, 8 Apr 2009)*
618 - Change the internal locking model of some ``gnt-node`` commands, in
619 order to reduce contention (and blocking of master daemon) when
620 batching many creation/reinstall jobs
621 - Fixes to Xen soft reboot
622 - No longer build documentation at build time, instead distribute it in
623 the archive, in order to reduce the need for the whole docbook/rst
627 Version 2.0 release candidate 2
628 -------------------------------
630 *(Released Fri, 27 Mar 2009)*
632 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
633 - Fix watcher startup sequence, improves the behaviour of busy clusters
634 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
635 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
636 bind address and other places
637 - Some documentation fixes and updates
640 Version 2.0 release candidate 1
641 -------------------------------
643 *(Released Mon, 2 Mar 2009)*
645 - More documentation updates, now all docs should be more-or-less
647 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
649 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
651 - Fix an issue related to $libdir/run/ganeti and cluster creation
657 *(Released Thu, 19 Feb 2009)*
659 - Xen PVM and KVM have switched the default value for the instance root
660 disk to the first partition on the first drive, instead of the whole
661 drive; this means that the OS installation scripts must be changed
663 - Man pages have been updated
664 - RAPI has been switched by default to HTTPS, and the exported functions
665 should all work correctly
666 - RAPI v1 has been removed
667 - Many improvements to the KVM hypervisor
668 - Block device errors are now better reported
669 - Many other bugfixes and small improvements
675 *(Released Mon, 26 Jan 2009)*
677 - Version 2 is a general rewrite of the code and therefore the
678 differences are too many to list, see the design document for 2.0 in
679 the ``doc/`` subdirectory for more details
680 - In this beta version there is not yet a migration path from 1.2 (there
681 will be one in the final 2.0 release)
682 - A few significant changes are:
684 - all commands are executed by a daemon (``ganeti-masterd``) and the
685 various ``gnt-*`` commands are just front-ends to it
686 - all the commands are entered into, and executed from a job queue,
687 see the ``gnt-job(8)`` manpage
688 - the RAPI daemon supports read-write operations, secured by basic
689 HTTP authentication on top of HTTPS
690 - DRBD version 0.7 support has been removed, DRBD 8 is the only
691 supported version (when migrating from Ganeti 1.2 to 2.0, you need
692 to migrate to DRBD 8 first while still running Ganeti 1.2)
693 - DRBD devices are using statically allocated minor numbers, which
694 will be assigned to existing instances during the migration process
695 - there is support for both Xen PVM and Xen HVM instances running on
697 - KVM virtualization is supported too
698 - file-based storage has been implemented, which means that it is
699 possible to run the cluster without LVM and DRBD storage, for
700 example using a shared filesystem exported from shared storage (and
701 still have live migration)
707 *(Released Tue, 13 Jan 2009)*
709 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
710 - Reuse the old instance mac address by default on instance import, if
711 the instance name is the same.
712 - Handle situations in which the node info rpc returns incomplete
714 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
715 - Improved version of batcher:
718 - instance mac address support
719 - support for HVM clusters/instances
721 - Add an option to show the number of cpu sockets and nodes in
723 - Support OSes that handle more than one version of the OS api (but do
724 not change the current API in any other way)
725 - Fix ``gnt-node migrate``
726 - ``gnt-debug`` man page
727 - Fixes various more typos and small issues
728 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
734 *(Released Wed, 24 Sep 2008)*
736 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
737 type of disk exported to fully virtualized instances.
738 - provide access to the serial console of HVM instances
739 - instance auto_balance flag, set by default. If turned off it will
740 avoid warnings on cluster verify if there is not enough memory to fail
741 over an instance. in the future it will prevent automatically failing
742 it over when we will support that.
743 - batcher tool for instance creation, see ``tools/README.batcher``
744 - ``gnt-instance reinstall --select-os`` to interactively select a new
745 operating system when reinstalling an instance.
746 - when changing the memory amount on instance modify a check has been
747 added that the instance will be able to start. also warnings are
748 emitted if the instance will not be able to fail over, if auto_balance
750 - documentation fixes
751 - sync fields between ``gnt-instance list/modify/add/import``
752 - fix a race condition in drbd when the sync speed was set after giving
753 the device a remote peer.
759 *(Released Tue, 22 Jul 2008)*
761 - note: the allowed size and number of tags per object were reduced
762 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
763 - fixed twisted 8.x compatibility
764 - fixed ``gnt-instance replace-disks`` with iallocator
765 - add TCP keepalives on twisted connections to detect restarted nodes
766 - disk increase support, see ``gnt-instance grow-disk``
767 - implement bulk node/instance query for RAPI
768 - add tags in node/instance listing (optional)
769 - experimental migration (and live migration) support, read the man page
770 for ``gnt-instance migrate``
771 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
772 has some small improvements in handling its state file
778 *(Released Fri, 13 Jun 2008)*
780 - Experimental readonly, REST-based remote API implementation;
781 automatically started on master node, TCP port 5080, if enabled by
782 ``--enable-rapi`` parameter to configure script.
783 - Instance allocator support. Add and import instance accept a
784 ``--iallocator`` parameter, and call that instance allocator to decide
785 which node to use for the instance. The iallocator document describes
786 what's expected from an allocator script.
787 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
788 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
789 node is lost there is still enough memory to fail over the instances
791 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
792 ``gnt-cluster verify``, to check for site-specific compliance. All the
793 hooks will run, and their output, if any, will be displayed. Any
794 failing hook will make the verification return an error value.
795 - ``gnt-cluster verify`` now checks that its peers are reachable on the
796 primary and secondary interfaces
797 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
798 that is still declared as part of the cluster and has failed.
799 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
800 specifying output fields, that just adds the chosen fields to the
802 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
803 export from the filesystem.
804 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
805 have been added. Using them you can enable/disable acpi and pae
806 support, and specify a path for a cd image to be exported to the
807 instance. These parameters as the name suggest only work on HVM
809 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
810 PAE support will be set to the previously hardcoded values, but the
811 (previously hardcoded) path to the CDROM ISO image will be unset and
812 if required, needs to be set manually with ``gnt-instance modify``
814 - The address to which an instance's VNC console is bound is now
815 selectable per-instance, rather than being cluster wide. Of course
816 this only applies to instances controlled via VNC, so currently just
817 applies to HVM clusters.
823 *(Released Mon, 18 Feb 2008)*
825 - more tweaks to the disk activation code (especially helpful for DRBD)
826 - change the default ``gnt-instance list`` output format, now there is
827 one combined status field (see the manpage for the exact values this
829 - some more fixes for the mac export to hooks change
830 - make Ganeti not break with DRBD 8.2.x (which changed the version
831 format in ``/proc/drbd``) (issue 24)
832 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
833 template, allowing migration from DRBD0.7+MD to DRBD8
839 *(Released Wed, 30 Jan 2008)*
841 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
843 - add command aliases infrastructure and a few aliases
844 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
845 man pages and the ``--help`` option of ``gnt-node
846 list``/``gnt-instance list``
847 - fix ``gnt-backup list`` with down nodes (issue 21)
848 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
849 - fix the dist archive and add a check for including svn/git files in
851 - some developer-related changes: improve the burnin and the QA suite,
852 add an upload script for testing during development
858 *(Released Wed, 16 Jan 2008)*
860 - experimental HVM support, read the install document, section
861 "Initializing the cluster"
862 - allow for the PVM hypervisor per-instance kernel and initrd paths
863 - add a new command ``gnt-cluster verify-disks`` which uses a new
864 algorithm to improve the reconnection of the DRBD pairs if the device
865 on the secondary node has gone away
866 - make logical volume code auto-activate LVs at disk activation time
867 - slightly improve the speed of activating disks
868 - allow specification of the MAC address at instance creation time, and
869 changing it later via ``gnt-instance modify``
870 - fix handling of external commands that generate lots of output on
872 - update documentation with regard to minimum version of DRBD8 supported
878 *(Released Tue, 4 Dec 2007)*
880 - Log the ``xm create`` output to the node daemon log on failure (to
881 help diagnosing the error)
882 - In debug mode, log all external commands output if failed to the logs
883 - Change parsing of lvm commands to ignore stderr
889 *(Released Wed, 28 Nov 2007)*
891 - Another round of updates to the DRBD 8 code to deal with more failures
892 in the replace secondary node operation
893 - Some more logging of failures in disk operations (lvm, drbd)
894 - A few documentation updates
901 *(Released Tue, 13 Nov 2007)*
903 - Change configuration file format from Python's Pickle to JSON.
904 Upgrading is possible using the cfgupgrade utility.
905 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
906 faster replace disks and is more stable (DRBD 8 has many improvements
907 compared to DRBD 0.7)
908 - Added command line tags support (see man pages for ``gnt-instance``,
909 ``gnt-node``, ``gnt-cluster``)
910 - Added instance rename support
911 - Added multi-instance startup/shutdown
912 - Added cluster rename support
913 - Added ``gnt-node evacuate`` to simplify some node operations
914 - Added instance reboot operation that can speedup reboot as compared to
916 - Soften the requirement that hostnames are in FQDN format
917 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
919 - Removed dependency on debian's patched fping that uses the
920 non-standard ``-S`` option
921 - Now the OS definitions are searched for in multiple, configurable
922 paths (easier for distros to package)
923 - Some changes to the hooks infrastructure (especially the new
924 post-configuration update hook)
925 - Other small bugfixes
