7 *(Released Thu, 17 Jun 2010)*
9 - Added tool (``move-instance``) and infrastructure to move instances
10 between separate clusters (see :doc:`separate documentation
11 <move-instance>` and :doc:`design document <design-2.2>`)
12 - Added per-request RPC timeout
13 - RAPI now requires a Content-Type header for requests with a body (e.g.
14 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
15 RFC2616 (HTTP/1.1), section 7.2.1)
16 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
18 - Implemented initial support for running Ganeti daemons as separate
19 users, see configure-time flags ``--with-user-prefix`` and
20 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
22 - Instances can be removed after export (``gnt-backup export
24 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
25 key (instead of 1024 bit)
26 - Added new cluster configuration file for cluster domain secret
27 - Import/export now use SSL instead of SSH
28 - Added support for showing estimated time when exporting an instance,
29 see the ``ganeti-os-interface(7)`` manpage and look for
36 *(Released Thu, 3 Jun 2010)*
38 A medium sized development cycle. Some new features, and some
39 fixes/small improvements/cleanups.
44 The node deamon now tries to mlock itself into memory, unless the
45 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
46 its logs, and falls back to console logging. This allows emergency
47 features such as ``gnt-node powercycle`` to work even in the event of a
48 broken node disk (tested offlining the disk hosting the node's
49 filesystem and dropping its memory caches; don't try this at home)
51 KVM: add vhost-net acceleration support. It can be tested with a new
52 enough version of the kernel and of qemu-kvm.
54 KVM: Add instance chrooting feature. If you use privilege dropping for
55 your VMs you can also now force them to chroot to an empty directory,
56 before starting the emulated guest.
58 KVM: Add maximum migration bandwith and maximum downtime tweaking
59 support (requires a new-enough version of qemu-kvm).
61 Cluster verify will now warn if the master node doesn't have the master
64 Add a new (incompatible) instance creation request format to RAPI which
65 supports all parameters (previously only a subset was supported, and it
66 wasn't possible to extend the old format to accomodate all the new
67 features. The old format is still supported, and a client can check for
68 this feature, before using it, by checking for its presence in the
69 ``features`` RAPI resource.
71 Now with ancient latin support. Try it passing the ``--roman`` option to
72 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
73 (requires the python-roman module to be installed, in order to work).
78 As usual many internal code refactorings, documentation updates, and
81 - Lots of improvements and cleanups to the experimental Remote API
82 (RAPI) client library.
83 - A new unit test suite for the core daemon libraries.
84 - A fix to creating missing directories makes sure the umask is not
85 applied anymore. This enforces the same directory permissions
87 - Better handling terminating daemons with ctrl+c (used when running
88 them in debugging mode).
89 - Fix a race condition in live migrating a KVM instance, when stat()
90 on the old proc status file returned EINVAL, which is an unexpected
92 - Fixed manpage checking with newer man and utf-8 charachters. But now
93 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
99 *(Released Fri, 7 May 2010)*
101 Fix a bug which prevented untagged KVM instances from starting.
107 *(Released Fri, 7 May 2010)*
109 Another release with a long development cycle, during which many
110 different features were added.
115 The KVM hypervisor now can run the individual instances as non-root, to
116 reduce the impact of a VM being hijacked due to bugs in the
117 hypervisor. It is possible to run all instances as a single (non-root)
118 user, to manually specify a user for each instance, or to dynamically
119 allocate a user out of a cluster-wide pool to each instance, with the
120 guarantee that no two instances will run under the same user ID on any
123 An experimental RAPI client library, that can be used standalone
124 (without the other Ganeti libraries), is provided in the source tree as
125 ``lib/rapi/client.py``. Note this client might change its interface in
126 the future, as we iterate on its capabilities.
128 A new command, ``gnt-cluster renew-crypto`` has been added to easily
129 replace the cluster's certificates and crypto keys. This might help in
130 case they have been compromised, or have simply expired.
132 A new disk option for instance creation has been added that allows one
133 to "adopt" currently existing logical volumes, with data
134 preservation. This should allow easier migration to Ganeti from
135 unmanaged (or managed via other software) instances.
137 Another disk improvement is the possibility to convert between redundant
138 (DRBD) and plain (LVM) disk configuration for an instance. This should
139 allow better scalability (starting with one node and growing the
140 cluster, or shrinking a two-node cluster to one node).
142 A new feature that could help with automated node failovers has been
143 implemented: if a node sees itself as offline (by querying the master
144 candidates), it will try to shutdown (hard) all instances and any active
145 DRBD devices. This reduces the risk of duplicate instances if an
146 external script automatically failovers the instances on such nodes. To
147 enable this, the cluster parameter ``maintain_node_health`` should be
148 enabled; in the future this option (per the name) will enable other
149 automatic maintenance features.
151 Instance export/import now will reuse the original instance
152 specifications for all parameters; that means exporting an instance,
153 deleting it and the importing it back should give an almost identical
154 instance. Note that the default import behaviour has changed from
155 before, where it created only one NIC; now it recreates the original
158 Cluster verify has added a few new checks: SSL certificates validity,
159 /etc/hosts consistency across the cluster, etc.
164 As usual, many internal changes were done, documentation fixes,
167 - Fixed cluster initialization with disabled cluster storage (regression
169 - File-based storage supports growing the disks
170 - Fixed behaviour of node role changes
171 - Fixed cluster verify for some corner cases, plus a general rewrite of
172 cluster verify to allow future extension with more checks
173 - Fixed log spamming by watcher and node daemon (regression introduced
175 - Fixed possible validation issues when changing the list of enabled
177 - Fixed cleanup of /etc/hosts during node removal
178 - Fixed RAPI response for invalid methods
179 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
180 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
181 from ide disks, etc.)
182 - Allow OS changes without re-installation (to record a changed OS
183 outside of Ganeti, or to allow OS renames)
184 - Allow instance creation without OS installation (useful for example if
185 the OS will be installed manually, or restored from a backup not in
187 - Implemented option to make cluster ``copyfile`` use the replication
189 - Added list of enabled hypervisors to ssconf (possibly useful for
191 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
193 - A partial form of node re-IP is possible via node readd, which now
194 allows changed node primary IP
195 - Command line utilities now show an informational message if the job is
197 - The logs of the master daemon now show the PID/UID/GID of the
204 *(Released Fri, 12 Mar 2010)*
206 During the 2.1.0 long release candidate cycle, a lot of improvements and
207 changes have accumulated with were released later as 2.1.1.
212 The node evacuate command (``gnt-node evacuate``) was significantly
213 rewritten, and as such the IAllocator protocol was changed - a new
214 request type has been added. This unfortunate change during a stable
215 series is designed to improve performance of node evacuations; on
216 clusters with more than about five nodes and which are well-balanced,
217 evacuation should proceed in parallel for all instances of the node
218 being evacuated. As such, any existing IAllocator scripts need to be
219 updated, otherwise the above command will fail due to the unknown
220 request. The provided "dumb" allocator has not been updated; but the
221 ganeti-htools package supports the new protocol since version 0.2.4.
223 Another important change is increased validation of node and instance
224 names. This might create problems in special cases, if invalid host
225 names are being used.
227 Also, a new layer of hypervisor parameters has been added, that sits at
228 OS level between the cluster defaults and the instance ones. This allows
229 customisation of virtualization parameters depending on the installed
230 OS. For example instances with OS 'X' may have a different KVM kernel
231 (or any other parameter) than the cluster defaults. This is intended to
232 help managing a multiple OSes on the same cluster, without manual
233 modification of each instance's parameters.
235 A tool for merging clusters, ``cluster-merge``, has been added in the
241 - Improved the int/float conversions that should make the code more
242 robust in face of errors from the node daemons
243 - Fixed the remove node code in case of internal configuration errors
244 - Fixed the node daemon behaviour in face of inconsistent queue
245 directory (e.g. read-only file-system where we can't open the files
247 - Fixed the behaviour of gnt-node modify for master candidate demotion;
248 now it either aborts cleanly or, if given the new “auto_promote”
249 parameter, will automatically promote other nodes as needed
250 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
251 completely prevent Ganeti from working
252 - Fixed bug for instance export when not all disks were successfully
254 - Fixed behaviour of node add when the new node is slow in starting up
256 - Fixed handling of signals in the LUXI client, which should improve
257 behaviour of command-line scripts
258 - Added checks for invalid node/instance names in the configuration (now
259 flagged during cluster verify)
260 - Fixed watcher behaviour for disk activation errors
261 - Fixed two potentially endless loops in http library, which led to the
262 RAPI daemon hanging and consuming 100% CPU in some cases
263 - Fixed bug in RAPI daemon related to hashed passwords
264 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
266 - Enhanced compatibility with non-Debian OSes, but not using absolute
267 path in some commands and allowing customisation of the ssh
268 configuration directory
269 - Fixed possible future issue with new Python versions by abiding to the
270 proper use of ``__slots__`` attribute on classes
271 - Added checks that should prevent directory traversal attacks
272 - Many documentation fixes based on feedback from users
277 - Added an “early_release” more for instance replace disks and node
278 evacuate, where we release locks earlier and thus allow higher
279 parallelism within the cluster
280 - Added watcher hooks, intended to allow the watcher to restart other
281 daemons (e.g. from the ganeti-nbma project), but they can be used of
282 course for any other purpose
283 - Added a compile-time disable for DRBD barriers, to increase
284 performance if the administrator trusts the power supply or the
285 storage system to not lose writes
286 - Added the option of using syslog for logging instead of, or in
287 addition to, Ganeti's own log files
288 - Removed boot restriction for paravirtual NICs for KVM, recent versions
289 can indeed boot from a paravirtual NIC
290 - Added a generic debug level for many operations; while this is not
291 used widely yet, it allows one to pass the debug value all the way to
293 - Enhanced the hooks environment for instance moves (failovers,
294 migrations) where the primary/secondary nodes changed during the
295 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
296 - Enhanced data validations for many user-supplied values; one important
297 item is the restrictions imposed on instance and node names, which
298 might reject some (invalid) host names
299 - Add a configure-time option to disable file-based storage, if it's not
300 needed; this allows greater security separation between the master
301 node and the other nodes from the point of view of the inter-node RPC
303 - Added user notification in interactive tools if job is waiting in the
304 job queue or trying to acquire locks
305 - Added log messages when a job is waiting for locks
306 - Added filtering by node tags in instance operations which admit
307 multiple instances (start, stop, reboot, reinstall)
308 - Added a new tool for cluster mergers, ``cluster-merge``
309 - Parameters from command line which are of the form ``a=b,c=d`` can now
310 use backslash escapes to pass in values which contain commas,
311 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
313 - For KVM, the instance name is the first parameter passed to KVM, so
314 that it's more visible in the process list
320 *(Released Tue, 2 Mar 2010)*
322 Ganeti 2.1 brings many improvements with it. Major changes:
324 - Added infrastructure to ease automated disk repairs
325 - Added new daemon to export configuration data in a cheaper way than
327 - Instance NICs can now be routed instead of being associated with a
329 - Improved job locking logic to reduce impact of jobs acquiring multiple
330 locks waiting for other long-running jobs
332 In-depth implementation details can be found in the Ganeti 2.1 design
338 - Added chroot hypervisor
339 - Added more options to xen-hvm hypervisor (``kernel_path`` and
341 - Added more options to xen-pvm hypervisor (``use_bootloader``,
342 ``bootloader_path`` and ``bootloader_args``)
343 - Added the ``use_localtime`` option for the xen-hvm and kvm
344 hypervisors, and the default value for this has changed to false (in
345 2.0 xen-hvm always enabled it)
346 - Added luxi call to submit multiple jobs in one go
347 - Added cluster initialization option to not modify ``/etc/hosts``
349 - Added network interface parameters
350 - Added dry run mode to some LUs
351 - Added RAPI resources:
353 - ``/2/instances/[instance_name]/info``
354 - ``/2/instances/[instance_name]/replace-disks``
355 - ``/2/nodes/[node_name]/evacuate``
356 - ``/2/nodes/[node_name]/migrate``
357 - ``/2/nodes/[node_name]/role``
358 - ``/2/nodes/[node_name]/storage``
359 - ``/2/nodes/[node_name]/storage/modify``
360 - ``/2/nodes/[node_name]/storage/repair``
362 - Added OpCodes to evacuate or migrate all instances on a node
363 - Added new command to list storage elements on nodes (``gnt-node
364 list-storage``) and modify them (``gnt-node modify-storage``)
365 - Added new ssconf files with master candidate IP address
366 (``ssconf_master_candidates_ips``), node primary IP address
367 (``ssconf_node_primary_ips``) and node secondary IP address
368 (``ssconf_node_secondary_ips``)
369 - Added ``ganeti-confd`` and a client library to query the Ganeti
370 configuration via UDP
371 - Added ability to run hooks after cluster initialization and before
373 - Added automatic mode for disk replace (``gnt-instance replace-disks
375 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
376 after catastrophic data-loss
377 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
379 - Added ``gnt-instance move`` command to move instances
380 - Added ``gnt-cluster watcher`` command to control watcher
381 - Added ``gnt-node powercycle`` command to powercycle nodes
382 - Added new job status field ``lock_status``
383 - Added parseable error codes to cluster verification (``gnt-cluster
384 verify --error-codes``) and made output less verbose (use
385 ``--verbose`` to restore previous behaviour)
386 - Added UUIDs to the main config entities (cluster, nodes, instances)
387 - Added support for OS variants
388 - Added support for hashed passwords in the Ganeti remote API users file
390 - Added option to specify maximum timeout on instance shutdown
391 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
392 - Added new helper script to start and stop Ganeti daemons
393 (``daemon-util``), with the intent to reduce the work necessary to
394 adjust Ganeti for non-Debian distributions and to start/stop daemons
396 - Added more unittests
397 - Fixed critical bug in ganeti-masterd startup
398 - Removed the configure-time ``kvm-migration-port`` parameter, this is
399 now customisable at the cluster level for both the KVM and Xen
400 hypervisors using the new ``migration_port`` parameter
401 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
402 reinstalling an instance
403 - Allowed ``@`` in tag names

413 - Match instance and node names case insensitively
414 - Reimplemented bash completion script to be more complete
421 *(Released Thu, 4 Feb 2010)*
423 - Fix cleaner behaviour on nodes not in a cluster (Debian bug 568105)
424 - Fix a string formatting bug
425 - Improve safety of the code in some error paths
426 - Improve data validation in the master of values returned from nodes
432 *(Released Thu, 17 Dec 2009)*
434 - Fix security issue due to missing validation of iallocator names; this
435 allows local and remote execution of arbitrary executables
436 - Fix failure of gnt-node list during instance removal
437 - Ship the RAPI documentation in the archive
443 *(Released Wed, 30 Sep 2009)*
445 - Fixed many wrong messages
446 - Fixed a few bugs related to the locking library
447 - Fixed MAC checking at instance creation time
448 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
449 - Fixed a few issues related to signal handling in both daemons and
451 - Fixed the example startup script provided
452 - Fixed insserv dependencies in the example startup script (patch from
454 - Fixed handling of drained nodes in the iallocator framework
455 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
457 - Fixed error related to invalid job IDs in job polling
458 - Fixed job/opcode persistence on unclean master shutdown
459 - Fixed handling of partial job processing after unclean master
461 - Fixed error reporting from LUs, previously all errors were converted
462 into execution errors
463 - Fixed error reporting from burnin
464 - Decreased significantly the memory usage of the job queue
465 - Optimised slightly multi-job submission
466 - Optimised slightly opcode loading
467 - Backported the multi-job submit framework from the development
468 branch; multi-instance start and stop should be faster
469 - Added script to clean archived jobs after 21 days; this will reduce
470 the size of the queue directory
471 - Added some extra checks in disk size tracking
472 - Added an example ethers hook script
473 - Added a cluster parameter that prevents Ganeti from modifying of
475 - Added more node information to RAPI responses
476 - Added a ``gnt-job watch`` command that allows following the ouput of a
478 - Added a bind-address option to ganeti-rapi
479 - Added more checks to the configuration verify
480 - Enhanced the burnin script such that some operations can be retried
482 - Converted instance reinstall to multi-instance model
488 *(Released Fri, 7 Aug 2009)*
490 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
491 to allow using the pre-2.0.2 behaviour in activation, if any existing
492 instances have mismatched disk sizes in the configuration
493 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
494 any configuration mismatches for disk sizes
495 - Added ``gnt-master cluste-failover --no-voting`` to allow master
496 failover to work on two-node clusters
497 - Fixed the ``--net`` option of ``gnt-backup import``, which was
499 - Fixed detection of OS script errors in ``gnt-backup export``
500 - Fixed exit code of ``gnt-backup export``
506 *(Released Fri, 17 Jul 2009)*
508 - Added experimental support for stripped logical volumes; this should
509 enhance performance but comes with a higher complexity in the block
510 device handling; stripping is only enabled when passing
511 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
512 affected even in the non-stripped mode
513 - Improved resiliency against transient failures at the end of DRBD
514 resyncs, and in general of DRBD resync checks
515 - Fixed a couple of issues with exports and snapshot errors
516 - Fixed a couple of issues in instance listing
517 - Added display of the disk size in ``gnt-instance info``
518 - Fixed checking for valid OSes in instance creation
519 - Fixed handling of the "vcpus" parameter in instance listing and in
520 general of invalid parameters
521 - Fixed http server library, and thus RAPI, to handle invalid
522 username/password combinations correctly; this means that now they
523 report unauthorized for queries too, not only for modifications,
524 allowing earlier detect of configuration problems
525 - Added a new "role" node list field, equivalent to the master/master
526 candidate/drained/offline flags combinations
527 - Fixed cluster modify and changes of candidate pool size
528 - Fixed cluster verify error messages for wrong files on regular nodes
529 - Fixed a couple of issues with node demotion from master candidate role
530 - Fixed node readd issues
531 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
532 - Added a new ``--no-voting`` option for masterfailover to fix failover
533 on two-nodes clusters when the former master node is unreachable
534 - Added instance reinstall over RAPI
540 *(Released Tue, 16 Jun 2009)*
542 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
543 allow re-adding the start in single-user option (regression from 1.2)
544 - the watcher writes the instance status to a file, to allow monitoring
545 to report the instance status (from the master) based on cached
546 results of the watcher's queries; while this can get stale if the
547 watcher is being locked due to other work on the cluster, this is
549 - the watcher now also restarts the node daemon and the rapi daemon if
551 - fixed the watcher to handle full and drained queue cases
552 - hooks export more instance data in the environment, which helps if
553 hook scripts need to take action based on the instance's properties
554 (no longer need to query back into ganeti)
555 - instance failovers when the instance is stopped do not check for free
556 RAM, so that failing over a stopped instance is possible in low memory
558 - rapi uses queries for tags instead of jobs (for less job traffic), and
559 for cluster tags it won't talk to masterd at all but read them from
561 - a couple of error handling fixes in RAPI
562 - drbd handling: improved the error handling of inconsistent disks after
563 resync to reduce the frequency of "there are some degraded disks for
564 this instance" messages
565 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
566 error handling path called a wrong function name)
572 *(Released Wed, 27 May 2009)*
574 - no changes from rc5
577 Version 2.0 release candidate 5
578 -------------------------------
580 *(Released Wed, 20 May 2009)*
582 - fix a couple of bugs (validation, argument checks)
583 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
584 - some small improvements to RAPI and IAllocator
585 - make watcher automatically start the master daemon if down
588 Version 2.0 release candidate 4
589 -------------------------------
591 *(Released Mon, 27 Apr 2009)*
593 - change the OS list to not require locks; this helps with big clusters
594 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
595 volume group is broken
596 - ``gnt-instance info``, without any arguments, doesn't run for all
597 instances anymore; either pass ``--all`` or pass the desired
598 instances; this helps against mistakes on big clusters where listing
599 the information for all instances takes a long time
600 - miscellaneous doc and man pages fixes
603 Version 2.0 release candidate 3
604 -------------------------------
606 *(Released Wed, 8 Apr 2009)*
608 - Change the internal locking model of some ``gnt-node`` commands, in
609 order to reduce contention (and blocking of master daemon) when
610 batching many creation/reinstall jobs
611 - Fixes to Xen soft reboot
612 - No longer build documentation at build time, instead distribute it in
613 the archive, in order to reduce the need for the whole docbook/rst
617 Version 2.0 release candidate 2
618 -------------------------------
620 *(Released Fri, 27 Mar 2009)*
622 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
623 - Fix watcher startup sequence, improves the behaviour of busy clusters
624 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
625 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
626 bind address and other places
627 - Some documentation fixes and updates
630 Version 2.0 release candidate 1
631 -------------------------------
633 *(Released Mon, 2 Mar 2009)*
635 - More documentation updates, now all docs should be more-or-less
637 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
639 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
641 - Fix an issue related to $libdir/run/ganeti and cluster creation
647 *(Released Thu, 19 Feb 2009)*
649 - Xen PVM and KVM have switched the default value for the instance root
650 disk to the first partition on the first drive, instead of the whole
651 drive; this means that the OS installation scripts must be changed
653 - Man pages have been updated
654 - RAPI has been switched by default to HTTPS, and the exported functions
655 should all work correctly
656 - RAPI v1 has been removed
657 - Many improvements to the KVM hypervisor
658 - Block device errors are now better reported
659 - Many other bugfixes and small improvements
665 *(Released Mon, 26 Jan 2009)*
667 - Version 2 is a general rewrite of the code and therefore the
668 differences are too many to list, see the design document for 2.0 in
669 the ``doc/`` subdirectory for more details
670 - In this beta version there is not yet a migration path from 1.2 (there
671 will be one in the final 2.0 release)
672 - A few significant changes are:
674 - all commands are executed by a daemon (``ganeti-masterd``) and the
675 various ``gnt-*`` commands are just front-ends to it
676 - all the commands are entered into, and executed from a job queue,
677 see the ``gnt-job(8)`` manpage
678 - the RAPI daemon supports read-write operations, secured by basic
679 HTTP authentication on top of HTTPS
680 - DRBD version 0.7 support has been removed, DRBD 8 is the only
681 supported version (when migrating from Ganeti 1.2 to 2.0, you need
682 to migrate to DRBD 8 first while still running Ganeti 1.2)
683 - DRBD devices are using statically allocated minor numbers, which
684 will be assigned to existing instances during the migration process
685 - there is support for both Xen PVM and Xen HVM instances running on
687 - KVM virtualization is supported too
688 - file-based storage has been implemented, which means that it is
689 possible to run the cluster without LVM and DRBD storage, for
690 example using a shared filesystem exported from shared storage (and
691 still have live migration)
697 *(Released Tue, 13 Jan 2009)*
699 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
700 - Reuse the old instance mac address by default on instance import, if
701 the instance name is the same.
702 - Handle situations in which the node info rpc returns incomplete
704 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
705 - Improved version of batcher:
708 - instance mac address support
709 - support for HVM clusters/instances
711 - Add an option to show the number of cpu sockets and nodes in
713 - Support OSes that handle more than one version of the OS api (but do
714 not change the current API in any other way)
715 - Fix ``gnt-node migrate``
716 - ``gnt-debug`` man page
717 - Fixes various more typos and small issues
718 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
724 *(Released Wed, 24 Sep 2008)*
726 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
727 type of disk exported to fully virtualized instances.
728 - provide access to the serial console of HVM instances
729 - instance auto_balance flag, set by default. If turned off it will
730 avoid warnings on cluster verify if there is not enough memory to fail
731 over an instance. in the future it will prevent automatically failing
732 it over when we will support that.
733 - batcher tool for instance creation, see ``tools/README.batcher``
734 - ``gnt-instance reinstall --select-os`` to interactively select a new
735 operating system when reinstalling an instance.
736 - when changing the memory amount on instance modify a check has been
737 added that the instance will be able to start. also warnings are
738 emitted if the instance will not be able to fail over, if auto_balance
740 - documentation fixes
741 - sync fields between ``gnt-instance list/modify/add/import``
742 - fix a race condition in drbd when the sync speed was set after giving
743 the device a remote peer.
749 *(Released Tue, 22 Jul 2008)*
751 - note: the allowed size and number of tags per object were reduced
752 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
753 - fixed twisted 8.x compatibility
754 - fixed ``gnt-instance replace-disks`` with iallocator
755 - add TCP keepalives on twisted connections to detect restarted nodes
756 - disk increase support, see ``gnt-instance grow-disk``
757 - implement bulk node/instance query for RAPI
758 - add tags in node/instance listing (optional)
759 - experimental migration (and live migration) support, read the man page
760 for ``gnt-instance migrate``
761 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
762 has some small improvements in handling its state file
768 *(Released Fri, 13 Jun 2008)*
770 - Experimental readonly, REST-based remote API implementation;
771 automatically started on master node, TCP port 5080, if enabled by
772 ``--enable-rapi`` parameter to configure script.
773 - Instance allocator support. Add and import instance accept a
774 ``--iallocator`` parameter, and call that instance allocator to decide
775 which node to use for the instance. The iallocator document describes
776 what's expected from an allocator script.
777 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
778 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
779 node is lost there is still enough memory to fail over the instances
781 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
782 ``gnt-cluster verify``, to check for site-specific compliance. All the
783 hooks will run, and their output, if any, will be displayed. Any
784 failing hook will make the verification return an error value.
785 - ``gnt-cluster verify`` now checks that its peers are reachable on the
786 primary and secondary interfaces
787 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
788 that is still declared as part of the cluster and has failed.
789 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
790 specifying output fields, that just adds the chosen fields to the
792 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
793 export from the filesystem.
794 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
795 have been added. Using them you can enable/disable acpi and pae
796 support, and specify a path for a cd image to be exported to the
797 instance. These parameters as the name suggest only work on HVM
799 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
800 PAE support will be set to the previously hardcoded values, but the
801 (previously hardcoded) path to the CDROM ISO image will be unset and
802 if required, needs to be set manually with ``gnt-instance modify``
804 - The address to which an instance's VNC console is bound is now
805 selectable per-instance, rather than being cluster wide. Of course
806 this only applies to instances controlled via VNC, so currently just
807 applies to HVM clusters.
813 *(Released Mon, 18 Feb 2008)*
815 - more tweaks to the disk activation code (especially helpful for DRBD)
816 - change the default ``gnt-instance list`` output format, now there is
817 one combined status field (see the manpage for the exact values this
819 - some more fixes for the mac export to hooks change
820 - make Ganeti not break with DRBD 8.2.x (which changed the version
821 format in ``/proc/drbd``) (issue 24)
822 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
823 template, allowing migration from DRBD0.7+MD to DRBD8
829 *(Released Wed, 30 Jan 2008)*
831 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
833 - add command aliases infrastructure and a few aliases
834 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
835 man pages and the ``--help`` option of ``gnt-node
836 list``/``gnt-instance list``
837 - fix ``gnt-backup list`` with down nodes (issue 21)
838 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
839 - fix the dist archive and add a check for including svn/git files in
841 - some developer-related changes: improve the burnin and the QA suite,
842 add an upload script for testing during development
848 *(Released Wed, 16 Jan 2008)*
850 - experimental HVM support, read the install document, section
851 "Initializing the cluster"
852 - allow for the PVM hypervisor per-instance kernel and initrd paths
853 - add a new command ``gnt-cluster verify-disks`` which uses a new
854 algorithm to improve the reconnection of the DRBD pairs if the device
855 on the secondary node has gone away
856 - make logical volume code auto-activate LVs at disk activation time
857 - slightly improve the speed of activating disks
858 - allow specification of the MAC address at instance creation time, and
859 changing it later via ``gnt-instance modify``
860 - fix handling of external commands that generate lots of output on
862 - update documentation with regard to minimum version of DRBD8 supported
868 *(Released Tue, 4 Dec 2007)*
870 - Log the ``xm create`` output to the node daemon log on failure (to
871 help diagnosing the error)
872 - In debug mode, log all external commands output if failed to the logs
873 - Change parsing of lvm commands to ignore stderr
879 *(Released Wed, 28 Nov 2007)*
881 - Another round of updates to the DRBD 8 code to deal with more failures
882 in the replace secondary node operation
883 - Some more logging of failures in disk operations (lvm, drbd)
884 - A few documentation updates
891 *(Released Tue, 13 Nov 2007)*
893 - Change configuration file format from Python's Pickle to JSON.
894 Upgrading is possible using the cfgupgrade utility.
895 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
896 faster replace disks and is more stable (DRBD 8 has many improvements
897 compared to DRBD 0.7)
898 - Added command line tags support (see man pages for ``gnt-instance``,
899 ``gnt-node``, ``gnt-cluster``)
900 - Added instance rename support
901 - Added multi-instance startup/shutdown
902 - Added cluster rename support
903 - Added ``gnt-node evacuate`` to simplify some node operations
904 - Added instance reboot operation that can speedup reboot as compared to
906 - Soften the requirement that hostnames are in FQDN format
907 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
909 - Removed dependency on debian's patched fping that uses the
910 non-standard ``-S`` option
911 - Now the OS definitions are searched for in multiple, configurable
912 paths (easier for distros to package)
913 - Some changes to the hooks infrastructure (especially the new
914 post-configuration update hook)
915 - Other small bugfixes
