9 - The default of the ``/2/instances/[instance_name]/rename`` RAPI
10 resource's ``ip_check`` parameter changed from ``True`` to ``False``
11 to match the underlying LUXI interface
12 - When creating file-based instances via RAPI, the ``file_driver``
13 parameter no longer defaults to ``loop`` and must be specified
19 *(Released Mon, 21 Feb 2011)*
21 A number of bug fixes plus just a couple functionality changes.
23 On the user-visible side, the ``gnt-* list`` command output has changed
24 with respect to “special” field states. The current rc1 style of display
25 can be re-enabled by passing a new ``-v, --verbose`` flag, but in the
26 default output mode special fields are displayed as follows:
28 - offline field: ``*``
29 - unavailable/not applicable: ``-``
30 - data missing (RPC failure): ``?``
31 - unknown field: ``??``
33 Another user-visible change is the addition of ``--force-join`` to
38 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
39 - fixed regression in RAPI/instance reinstall where all parameters were
40 required (instead of optional)
41 - fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
42 - fixed iallocator usage (offline nodes were not considered offline)
43 - fixed ``gnt-node list`` with respect to non-vm_capable nodes
44 - fixed hypervisor and OS parameter validation with respect to
46 - fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
48 - fixed ``tools/listrunner`` with respect to agent-based usage
54 *(Released Fri, 4 Feb 2011)*
56 Many changes and fixes since the beta1 release. While there were some
57 internal changes, the code has been mostly stabilised for the RC
60 Note: the dumb allocator was removed in this release, as it was not kept
61 up-to-date with the IAllocator protocol changes. It is recommended to
62 use the ``hail`` command from the ganeti-htools package.
64 Note: the 2.4 and up versions of Ganeti are not compatible with the
65 0.2.x branch of ganeti-htools. You need to upgrade to
66 ganeti-htools-0.3.0 (or later).
68 Regressions fixed from 2.3
69 ~~~~~~~~~~~~~~~~~~~~~~~~~~
71 - Fixed the ``gnt-cluster verify-disks`` command

80 - Fixed corner case in KVM handling of NICs
81 - Fixed many cases of wrong handling of non-vm_capable nodes
82 - Fixed a bug where a missing instance symlink was not possible to

84 activate-disks`` does it)
85 - Fixed the volume group name as reported by ``gnt-cluster
87 - Increased timeouts for the import-export code, hopefully leading to
88 fewer aborts due network or instance timeouts

91 initialisation, but only at the first watcher run
92 - Fixed many bugs in the OOB implementation
93 - Fixed watcher behaviour in presence of instances with offline
95 - Fixed instance list output for instances running on the wrong node
96 - a few fixes to the cluster-merge tool, but it still cannot merge
97 multi-node groups (currently it is not recommended to use this tool)
103 - Improved network configuration for the KVM hypervisor
104 - Added e1000 as a supported NIC for Xen-HVM
105 - Improved the lvmstrap tool to also be able to use partitions, as
106 opposed to full disks
107 - Improved speed of disk wiping (the cluster parameter
108 ``prealloc_wipe_disks``, so that it has a low impact on the total time
109 of instance creations
110 - Added documentation for the OS parameters
111 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
112 hypervisor is not responding
113 - Added display of blacklisted and hidden OS information in
115 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
116 NIC and node parameters, which might create problems with currently
117 invalid (but undetected) configuration files, but prevents validation
118 failures when unrelated parameters are modified
119 - Changed cluster initialisation to wait for the master daemon to become
121 - Expanded the RAPI interface:
123 - Added config redistribution resource
124 - Added activation/deactivation of instance disks
125 - Added export of console information
127 - Implemented log file reopening on SIGHUP, which allows using
128 logrotate(8) for the Ganeti log files
129 - Added a basic OOB helper script as an example
135 *(Released Fri, 14 Jan 2011)*
140 - Fixed timezone issues when formatting timestamps

158 - ``gnt-instance list-fields``
160 - Updated documentation and man pages
165 - Moved ``rapi_users`` file into separate directory, now named
166 ``…/ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
168 - Added new tool for running commands on many machines,
169 ``tools/ganeti-listrunner``
170 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also

175 - Added script to gracefully power off KVM instances
176 - Split ``utils`` module into smaller parts
177 - Changed query operations to return more detailed information, e.g.
178 whether an information is unavailable due to an offline node. To use
179 this new functionality, the LUXI call ``Query`` must be used. Field
180 information is now stored by the master daemon and can be retrieved
181 using ``QueryFields``. Instances, nodes and groups can also be queried
182 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
183 exposed via RAPI). The following commands make use of this
184 infrastructure change:
187 - ``gnt-group list-fields``
189 - ``gnt-node list-fields``
190 - ``gnt-instance list``
191 - ``gnt-instance list-fields``

277 - Simplify and extend the environment variables for instance OS scripts
278 - Added new node flags, ``master_capable`` and ``vm_capable``
279 - Added optional instance disk wiping prior during allocation. This is a
280 cluster-wide option and can be set/modified using
281 ``gnt-cluster {init,modify} --prealloc-wipe-disks``.
282 - Added IPv6 support, see :doc:`design document <design-2.3>` and
284 - Added a new watcher option (``--ignore-pause``)

404 locks is expected for a later 2.2.x release
405 - Fixed dry-run behaviour with many commands
406 - Support ``ssh-agent`` again when adding nodes
407 - Many additional bugfixes
413 *(Released Fri, 30 Jul 2010)*
415 Important change: the internal RPC mechanism between Ganeti nodes has
416 changed from using a home-grown http library (based on the Python base
417 libraries) to use the PycURL library. This requires that PycURL is
418 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
419 against GnuTLS by default. cURL's support for GnuTLS had known issues
420 before cURL 7.21.0 and we recommend using the latest cURL release or
421 linking against OpenSSL. Most other distributions already link PycURL
422 and cURL against OpenSSL. The command::
424 python -c 'import pycurl; print pycurl.version'
426 can be used to determine the libraries PycURL and cURL are linked
429 Other significant changes:
431 - Rewrote much of the internals of the job queue, in order to achieve
432 better parallelism; this decouples job query operations from the job
433 processing, and it should allow much nicer behaviour of the master
434 daemon under load, and it also has uncovered some long-standing bugs
435 related to the job serialisation (now fixed)
436 - Added a default iallocator setting to the cluster parameters,
437 eliminating the need to always pass nodes or an iallocator for
438 operations that require selection of new node(s)
439 - Added experimental support for the LXC virtualization method
440 - Added support for OS parameters, which allows the installation of
441 instances to pass parameter to OS scripts in order to customise the
443 - Added a hypervisor parameter controlling the migration type (live or
444 non-live), since hypervisors have various levels of reliability; this
445 has renamed the 'live' parameter to 'mode'
446 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
447 logical volumes, meaning that cluster verify will ignore them and not
448 flag their presence as errors
449 - The watcher will now reset the error count for failed instances after
450 8 hours, thus allowing self-healing if the problem that caused the
451 instances to be down/fail to start has cleared in the meantime
452 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
453 check for, and warn, if the drbd module parameter ``usermode_helper``
454 is not consistent with the cluster-wide setting; this is needed to
455 make diagnose easier of failed drbd creations
456 - Started adding base IPv6 support, but this is not yet
457 enabled/available for use
458 - Rename operations (cluster, instance) will now return the new name,
459 which is especially useful if a short name was passed in
460 - Added support for instance migration in RAPI
461 - Added a tool to pre-configure nodes for the SSH setup, before joining
462 them to the cluster; this will allow in the future a simplified model
463 for node joining (but not yet fully enabled in 2.2); this needs the
464 paramiko python library
465 - Fixed handling of name-resolving errors
466 - Fixed consistency of job results on the error path
467 - Fixed master-failover race condition when executed multiple times in
469 - Fixed many bugs related to the job queue (mostly introduced during the
470 2.2 development cycle, so not all are impacting 2.1)
471 - Fixed instance migration with missing disk symlinks
472 - Fixed handling of unknown jobs in ``gnt-job archive``
473 - And many other small fixes/improvements
477 - Enhanced both the unittest and the QA coverage
478 - Switched the opcode validation to a generic model, and extended the
479 validation to all opcode parameters
480 - Changed more parts of the code that write shell scripts to use the
482 - Switched the master daemon to use the asyncore library for the Luxi
489 *(Released Thu, 17 Jun 2010)*
491 - Added tool (``move-instance``) and infrastructure to move instances
492 between separate clusters (see :doc:`separate documentation
493 <move-instance>` and :doc:`design document <design-2.2>`)
494 - Added per-request RPC timeout
495 - RAPI now requires a Content-Type header for requests with a body (e.g.
496 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
497 :rfc:`2616` (HTTP/1.1), section 7.2.1)
498 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
500 - Implemented initial support for running Ganeti daemons as separate
501 users, see configure-time flags ``--with-user-prefix`` and
502 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
504 - Instances can be removed after export (``gnt-backup export
506 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
507 key (instead of 1024 bit)
508 - Added new cluster configuration file for cluster domain secret
509 - Import/export now use SSL instead of SSH
510 - Added support for showing estimated time when exporting an instance,
511 see the ``ganeti-os-interface(7)`` manpage and look for
518 *(Released Tue, 16 Nov 2010)*
520 Some more bugfixes. Unless critical bugs occur, this will be the last
523 - Fix case of MAC special-values
524 - Fix mac checker regex
525 - backend: Fix typo causing “out of range” error
526 - Add missing --units in gnt-instance list man page
532 *(Released Tue, 24 Aug 2010)*
535 - Don't ignore secondary node silently on non-mirrored disk templates
537 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
538 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
539 - Properly document the usb_mouse parameter
540 - Fix path in ganeti-rapi(8) (issue 116)
541 - Adjust error message when the ganeti user's .ssh directory is
543 - Add same-node-check when changing the disk template to drbd
549 *(Released Fri, 16 Jul 2010)*
552 - Add an option to only select some reboot types during qa/burnin.
553 (on some hypervisors consequent reboots are not supported)
554 - Fix infrequent race condition in master failover. Sometimes the old
555 master ip address would be still detected as up for a short time
556 after it was removed, causing failover to fail.
557 - Decrease mlockall warnings when the ctypes module is missing. On
558 Python 2.4 we support running even if no ctypes module is installed,
559 but we were too verbose about this issue.
560 - Fix building on old distributions, on which man doesn't have a
562 - Fix RAPI not to ignore the MAC address on instance creation
563 - Implement the old instance creation format in the RAPI client.
569 *(Released Thu, 01 Jul 2010)*
571 A small bugfix release:
572 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
573 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
574 a non-existing option
575 - Fix instance create: the --force-variant option was ignored
576 - Improve pylint 0.21 compatibility and warnings with Python 2.6
577 - Fix modify node storage with non-FQDN arguments
578 - Fix RAPI client to authenticate under Python 2.6 when used
579 for more than 5 requests needing authentication
580 - Fix gnt-instance modify -t (storage) giving a wrong error message
581 when converting a non-shutdown drbd instance to plain
587 *(Released Fri, 18 Jun 2010)*
589 A small bugfix release:
591 - Fix live migration of KVM instances started with older Ganeti
592 versions which had fewer hypervisor parameters
593 - Fix gnt-instance grow-disk on down instances
594 - Fix an error-reporting bug during instance migration
595 - Better checking of the ``--net`` and ``--disk`` values, to avoid
596 silently ignoring broken ones
597 - Fix an RPC error reporting bug affecting, for example, RAPI client
599 - Fix bug triggered by different API version os-es on different nodes
600 - Fix a bug in instance startup with custom hvparams: OS level
601 parameters would fail to be applied.
602 - Fix the RAPI client under Python 2.6 (but more work is needed to
603 make it work completely well with OpenSSL)
604 - Fix handling of errors when resolving names from DNS
610 *(Released Thu, 3 Jun 2010)*
612 A medium sized development cycle. Some new features, and some
613 fixes/small improvements/cleanups.
618 The node deamon now tries to mlock itself into memory, unless the
619 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
620 its logs, and falls back to console logging. This allows emergency
621 features such as ``gnt-node powercycle`` to work even in the event of a
622 broken node disk (tested offlining the disk hosting the node's
623 filesystem and dropping its memory caches; don't try this at home)
625 KVM: add vhost-net acceleration support. It can be tested with a new
626 enough version of the kernel and of qemu-kvm.
628 KVM: Add instance chrooting feature. If you use privilege dropping for
629 your VMs you can also now force them to chroot to an empty directory,
630 before starting the emulated guest.
632 KVM: Add maximum migration bandwith and maximum downtime tweaking
633 support (requires a new-enough version of qemu-kvm).
635 Cluster verify will now warn if the master node doesn't have the master
638 Add a new (incompatible) instance creation request format to RAPI which
639 supports all parameters (previously only a subset was supported, and it
640 wasn't possible to extend the old format to accomodate all the new
641 features. The old format is still supported, and a client can check for
642 this feature, before using it, by checking for its presence in the
643 ``features`` RAPI resource.
645 Now with ancient latin support. Try it passing the ``--roman`` option to
646 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
647 (requires the python-roman module to be installed, in order to work).
652 As usual many internal code refactorings, documentation updates, and
655 - Lots of improvements and cleanups to the experimental Remote API
656 (RAPI) client library.
657 - A new unit test suite for the core daemon libraries.
658 - A fix to creating missing directories makes sure the umask is not
659 applied anymore. This enforces the same directory permissions
661 - Better handling terminating daemons with ctrl+c (used when running
662 them in debugging mode).
663 - Fix a race condition in live migrating a KVM instance, when stat()
664 on the old proc status file returned EINVAL, which is an unexpected
666 - Fixed manpage checking with newer man and utf-8 charachters. But now
667 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
673 *(Released Fri, 7 May 2010)*
675 Fix a bug which prevented untagged KVM instances from starting.
681 *(Released Fri, 7 May 2010)*
683 Another release with a long development cycle, during which many
684 different features were added.
689 The KVM hypervisor now can run the individual instances as non-root, to
690 reduce the impact of a VM being hijacked due to bugs in the
691 hypervisor. It is possible to run all instances as a single (non-root)
692 user, to manually specify a user for each instance, or to dynamically
693 allocate a user out of a cluster-wide pool to each instance, with the
694 guarantee that no two instances will run under the same user ID on any
697 An experimental RAPI client library, that can be used standalone
698 (without the other Ganeti libraries), is provided in the source tree as
699 ``lib/rapi/client.py``. Note this client might change its interface in
700 the future, as we iterate on its capabilities.
702 A new command, ``gnt-cluster renew-crypto`` has been added to easily
703 replace the cluster's certificates and crypto keys. This might help in
704 case they have been compromised, or have simply expired.
706 A new disk option for instance creation has been added that allows one
707 to "adopt" currently existing logical volumes, with data
708 preservation. This should allow easier migration to Ganeti from
709 unmanaged (or managed via other software) instances.
711 Another disk improvement is the possibility to convert between redundant
712 (DRBD) and plain (LVM) disk configuration for an instance. This should
713 allow better scalability (starting with one node and growing the
714 cluster, or shrinking a two-node cluster to one node).
716 A new feature that could help with automated node failovers has been
717 implemented: if a node sees itself as offline (by querying the master
718 candidates), it will try to shutdown (hard) all instances and any active
719 DRBD devices. This reduces the risk of duplicate instances if an
720 external script automatically failovers the instances on such nodes. To
721 enable this, the cluster parameter ``maintain_node_health`` should be
722 enabled; in the future this option (per the name) will enable other
723 automatic maintenance features.
725 Instance export/import now will reuse the original instance
726 specifications for all parameters; that means exporting an instance,
727 deleting it and the importing it back should give an almost identical
728 instance. Note that the default import behaviour has changed from
729 before, where it created only one NIC; now it recreates the original
732 Cluster verify has added a few new checks: SSL certificates validity,
733 /etc/hosts consistency across the cluster, etc.
738 As usual, many internal changes were done, documentation fixes,
741 - Fixed cluster initialization with disabled cluster storage (regression
743 - File-based storage supports growing the disks
744 - Fixed behaviour of node role changes
745 - Fixed cluster verify for some corner cases, plus a general rewrite of
746 cluster verify to allow future extension with more checks
747 - Fixed log spamming by watcher and node daemon (regression introduced
749 - Fixed possible validation issues when changing the list of enabled
751 - Fixed cleanup of /etc/hosts during node removal
752 - Fixed RAPI response for invalid methods
753 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
754 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
755 from ide disks, etc.)
756 - Allow OS changes without re-installation (to record a changed OS
757 outside of Ganeti, or to allow OS renames)
758 - Allow instance creation without OS installation (useful for example if
759 the OS will be installed manually, or restored from a backup not in
761 - Implemented option to make cluster ``copyfile`` use the replication
763 - Added list of enabled hypervisors to ssconf (possibly useful for
765 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
767 - A partial form of node re-IP is possible via node readd, which now
768 allows changed node primary IP
769 - Command line utilities now show an informational message if the job is
771 - The logs of the master daemon now show the PID/UID/GID of the
778 *(Released Fri, 12 Mar 2010)*
780 During the 2.1.0 long release candidate cycle, a lot of improvements and
781 changes have accumulated with were released later as 2.1.1.
786 The node evacuate command (``gnt-node evacuate``) was significantly
787 rewritten, and as such the IAllocator protocol was changed - a new
788 request type has been added. This unfortunate change during a stable
789 series is designed to improve performance of node evacuations; on
790 clusters with more than about five nodes and which are well-balanced,
791 evacuation should proceed in parallel for all instances of the node
792 being evacuated. As such, any existing IAllocator scripts need to be
793 updated, otherwise the above command will fail due to the unknown
794 request. The provided "dumb" allocator has not been updated; but the
795 ganeti-htools package supports the new protocol since version 0.2.4.
797 Another important change is increased validation of node and instance
798 names. This might create problems in special cases, if invalid host
799 names are being used.
801 Also, a new layer of hypervisor parameters has been added, that sits at
802 OS level between the cluster defaults and the instance ones. This allows
803 customisation of virtualization parameters depending on the installed
804 OS. For example instances with OS 'X' may have a different KVM kernel
805 (or any other parameter) than the cluster defaults. This is intended to
806 help managing a multiple OSes on the same cluster, without manual
807 modification of each instance's parameters.
809 A tool for merging clusters, ``cluster-merge``, has been added in the
815 - Improved the int/float conversions that should make the code more
816 robust in face of errors from the node daemons
817 - Fixed the remove node code in case of internal configuration errors
818 - Fixed the node daemon behaviour in face of inconsistent queue
819 directory (e.g. read-only file-system where we can't open the files
821 - Fixed the behaviour of gnt-node modify for master candidate demotion;
822 now it either aborts cleanly or, if given the new “auto_promote”
823 parameter, will automatically promote other nodes as needed
824 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
825 completely prevent Ganeti from working
826 - Fixed bug for instance export when not all disks were successfully
828 - Fixed behaviour of node add when the new node is slow in starting up
830 - Fixed handling of signals in the LUXI client, which should improve
831 behaviour of command-line scripts
832 - Added checks for invalid node/instance names in the configuration (now
833 flagged during cluster verify)
834 - Fixed watcher behaviour for disk activation errors
835 - Fixed two potentially endless loops in http library, which led to the
836 RAPI daemon hanging and consuming 100% CPU in some cases
837 - Fixed bug in RAPI daemon related to hashed passwords
838 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
840 - Enhanced compatibility with non-Debian OSes, but not using absolute
841 path in some commands and allowing customisation of the ssh
842 configuration directory
843 - Fixed possible future issue with new Python versions by abiding to the
844 proper use of ``__slots__`` attribute on classes
845 - Added checks that should prevent directory traversal attacks
846 - Many documentation fixes based on feedback from users
851 - Added an “early_release” more for instance replace disks and node
852 evacuate, where we release locks earlier and thus allow higher
853 parallelism within the cluster
854 - Added watcher hooks, intended to allow the watcher to restart other
855 daemons (e.g. from the ganeti-nbma project), but they can be used of
856 course for any other purpose
857 - Added a compile-time disable for DRBD barriers, to increase
858 performance if the administrator trusts the power supply or the
859 storage system to not lose writes
860 - Added the option of using syslog for logging instead of, or in
861 addition to, Ganeti's own log files
862 - Removed boot restriction for paravirtual NICs for KVM, recent versions
863 can indeed boot from a paravirtual NIC
864 - Added a generic debug level for many operations; while this is not
865 used widely yet, it allows one to pass the debug value all the way to
867 - Enhanced the hooks environment for instance moves (failovers,
868 migrations) where the primary/secondary nodes changed during the
869 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
870 - Enhanced data validations for many user-supplied values; one important
871 item is the restrictions imposed on instance and node names, which
872 might reject some (invalid) host names
873 - Add a configure-time option to disable file-based storage, if it's not
874 needed; this allows greater security separation between the master
875 node and the other nodes from the point of view of the inter-node RPC
877 - Added user notification in interactive tools if job is waiting in the
878 job queue or trying to acquire locks
879 - Added log messages when a job is waiting for locks
880 - Added filtering by node tags in instance operations which admit
881 multiple instances (start, stop, reboot, reinstall)
882 - Added a new tool for cluster mergers, ``cluster-merge``
883 - Parameters from command line which are of the form ``a=b,c=d`` can now
884 use backslash escapes to pass in values which contain commas,
885 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
887 - For KVM, the instance name is the first parameter passed to KVM, so
888 that it's more visible in the process list
894 *(Released Tue, 2 Mar 2010)*
896 Ganeti 2.1 brings many improvements with it. Major changes:
898 - Added infrastructure to ease automated disk repairs
899 - Added new daemon to export configuration data in a cheaper way than
901 - Instance NICs can now be routed instead of being associated with a
903 - Improved job locking logic to reduce impact of jobs acquiring multiple
904 locks waiting for other long-running jobs

912 - Added chroot hypervisor
913 - Added more options to xen-hvm hypervisor (``kernel_path`` and
915 - Added more options to xen-pvm hypervisor (``use_bootloader``,
916 ``bootloader_path`` and ``bootloader_args``)
917 - Added the ``use_localtime`` option for the xen-hvm and kvm
918 hypervisors, and the default value for this has changed to false (in
919 2.0 xen-hvm always enabled it)
920 - Added luxi call to submit multiple jobs in one go
921 - Added cluster initialization option to not modify ``/etc/hosts``
923 - Added network interface parameters

936 - Added OpCodes to evacuate or migrate all instances on a node
937 - Added new command to list storage elements on nodes (``gnt-node
938 list-storage``) and modify them (``gnt-node modify-storage``)
939 - Added new ssconf files with master candidate IP address
940 (``ssconf_master_candidates_ips``), node primary IP address
941 (``ssconf_node_primary_ips``) and node secondary IP address
942 (``ssconf_node_secondary_ips``)
943 - Added ``ganeti-confd`` and a client library to query the Ganeti
944 configuration via UDP
945 - Added ability to run hooks after cluster initialization and before
947 - Added automatic mode for disk replace (``gnt-instance replace-disks
949 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks

959 ``--verbose`` to restore previous behaviour)
960 - Added UUIDs to the main config entities (cluster, nodes, instances)
961 - Added support for OS variants
962 - Added support for hashed passwords in the Ganeti remote API users file
964 - Added option to specify maximum timeout on instance shutdown
965 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
966 - Added new helper script to start and stop Ganeti daemons
967 (``daemon-util``), with the intent to reduce the work necessary to
968 adjust Ganeti for non-Debian distributions and to start/stop daemons
970 - Added more unittests
971 - Fixed critical bug in ganeti-masterd startup
972 - Removed the configure-time ``kvm-migration-port`` parameter, this is
973 now customisable at the cluster level for both the KVM and Xen
974 hypervisors using the new ``migration_port`` parameter
975 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
976 reinstalling an instance
977 - Allowed ``@`` in tag names

1000 - Improve data validation in the master of values returned from nodes
1006 *(Released Thu, 17 Dec 2009)*

1009 allows local and remote execution of arbitrary executables
1010 - Fix failure of gnt-node list during instance removal
1011 - Ship the RAPI documentation in the archive
1017 *(Released Wed, 30 Sep 2009)*
1019 - Fixed many wrong messages
1020 - Fixed a few bugs related to the locking library
1021 - Fixed MAC checking at instance creation time
1022 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1023 - Fixed a few issues related to signal handling in both daemons and
1025 - Fixed the example startup script provided
1026 - Fixed insserv dependencies in the example startup script (patch from
1028 - Fixed handling of drained nodes in the iallocator framework
1029 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1031 - Fixed error related to invalid job IDs in job polling
1032 - Fixed job/opcode persistence on unclean master shutdown
1033 - Fixed handling of partial job processing after unclean master
1035 - Fixed error reporting from LUs, previously all errors were converted
1036 into execution errors
1037 - Fixed error reporting from burnin
1038 - Decreased significantly the memory usage of the job queue
1039 - Optimised slightly multi-job submission
1040 - Optimised slightly opcode loading
1041 - Backported the multi-job submit framework from the development
1042 branch; multi-instance start and stop should be faster

1044 the size of the queue directory
1045 - Added some extra checks in disk size tracking
1046 - Added an example ethers hook script
1047 - Added a cluster parameter that prevents Ganeti from modifying of
1049 - Added more node information to RAPI responses
1050 - Added a ``gnt-job watch`` command that allows following the ouput of a
1052 - Added a bind-address option to ganeti-rapi
1053 - Added more checks to the configuration verify
1054 - Enhanced the burnin script such that some operations can be retried
1056 - Converted instance reinstall to multi-instance model
1062 *(Released Fri, 7 Aug 2009)*
1064 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1065 to allow using the pre-2.0.2 behaviour in activation, if any existing
1066 instances have mismatched disk sizes in the configuration
1067 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1068 any configuration mismatches for disk sizes
1069 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1070 failover to work on two-node clusters
1071 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1073 - Fixed detection of OS script errors in ``gnt-backup export``
1074 - Fixed exit code of ``gnt-backup export``
1080 *(Released Fri, 17 Jul 2009)*
1082 - Added experimental support for stripped logical volumes; this should
1083 enhance performance but comes with a higher complexity in the block
1084 device handling; stripping is only enabled when passing
1085 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1086 affected even in the non-stripped mode
1087 - Improved resiliency against transient failures at the end of DRBD
1088 resyncs, and in general of DRBD resync checks
1089 - Fixed a couple of issues with exports and snapshot errors
1090 - Fixed a couple of issues in instance listing
1091 - Added display of the disk size in ``gnt-instance info``
1092 - Fixed checking for valid OSes in instance creation
1093 - Fixed handling of the "vcpus" parameter in instance listing and in
1094 general of invalid parameters
1095 - Fixed http server library, and thus RAPI, to handle invalid
1096 username/password combinations correctly; this means that now they
1097 report unauthorized for queries too, not only for modifications,
1098 allowing earlier detect of configuration problems
1099 - Added a new "role" node list field, equivalent to the master/master
1100 candidate/drained/offline flags combinations
1101 - Fixed cluster modify and changes of candidate pool size
1102 - Fixed cluster verify error messages for wrong files on regular nodes
1103 - Fixed a couple of issues with node demotion from master candidate role
1104 - Fixed node readd issues
1105 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1106 - Added a new ``--no-voting`` option for masterfailover to fix failover
1107 on two-nodes clusters when the former master node is unreachable
1108 - Added instance reinstall over RAPI
1114 *(Released Tue, 16 Jun 2009)*
1116 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1117 allow re-adding the start in single-user option (regression from 1.2)
1118 - the watcher writes the instance status to a file, to allow monitoring
1119 to report the instance status (from the master) based on cached
1120 results of the watcher's queries; while this can get stale if the
1121 watcher is being locked due to other work on the cluster, this is
1122 still an improvement
1123 - the watcher now also restarts the node daemon and the rapi daemon if
1125 - fixed the watcher to handle full and drained queue cases
1126 - hooks export more instance data in the environment, which helps if
1127 hook scripts need to take action based on the instance's properties
1128 (no longer need to query back into ganeti)
1129 - instance failovers when the instance is stopped do not check for free
1130 RAM, so that failing over a stopped instance is possible in low memory
1132 - rapi uses queries for tags instead of jobs (for less job traffic), and
1133 for cluster tags it won't talk to masterd at all but read them from
1135 - a couple of error handling fixes in RAPI
1136 - drbd handling: improved the error handling of inconsistent disks after
1137 resync to reduce the frequency of "there are some degraded disks for
1138 this instance" messages
1139 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1140 error handling path called a wrong function name)
1146 *(Released Wed, 27 May 2009)*
1148 - no changes from rc5
1151 Version 2.0 release candidate 5
1152 -------------------------------

1157 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1158 - some small improvements to RAPI and IAllocator
1159 - make watcher automatically start the master daemon if down
1162 Version 2.0 release candidate 4
1163 -------------------------------
1165 *(Released Mon, 27 Apr 2009)*
1167 - change the OS list to not require locks; this helps with big clusters
1168 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1169 volume group is broken
1170 - ``gnt-instance info``, without any arguments, doesn't run for all
1171 instances anymore; either pass ``--all`` or pass the desired
1172 instances; this helps against mistakes on big clusters where listing
1173 the information for all instances takes a long time
1174 - miscellaneous doc and man pages fixes
1177 Version 2.0 release candidate 3
1178 -------------------------------
1180 *(Released Wed, 8 Apr 2009)*
1182 - Change the internal locking model of some ``gnt-node`` commands, in
1183 order to reduce contention (and blocking of master daemon) when
1184 batching many creation/reinstall jobs
1185 - Fixes to Xen soft reboot
1186 - No longer build documentation at build time, instead distribute it in
1187 the archive, in order to reduce the need for the whole docbook/rst
1191 Version 2.0 release candidate 2
1192 -------------------------------
1194 *(Released Fri, 27 Mar 2009)*
1196 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1197 - Fix watcher startup sequence, improves the behaviour of busy clusters
1198 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1199 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1200 bind address and other places
1201 - Some documentation fixes and updates
1204 Version 2.0 release candidate 1
1205 -------------------------------
1207 *(Released Mon, 2 Mar 2009)*
1209 - More documentation updates, now all docs should be more-or-less
1211 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1213 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1215 - Fix an issue related to $libdir/run/ganeti and cluster creation
1221 *(Released Thu, 19 Feb 2009)*
1223 - Xen PVM and KVM have switched the default value for the instance root
1224 disk to the first partition on the first drive, instead of the whole
1225 drive; this means that the OS installation scripts must be changed
1227 - Man pages have been updated
1228 - RAPI has been switched by default to HTTPS, and the exported functions
1229 should all work correctly
1230 - RAPI v1 has been removed
1231 - Many improvements to the KVM hypervisor
1232 - Block device errors are now better reported
1233 - Many other bugfixes and small improvements
1239 *(Released Mon, 26 Jan 2009)*
1241 - Version 2 is a general rewrite of the code and therefore the
1242 differences are too many to list, see the design document for 2.0 in
1243 the ``doc/`` subdirectory for more details
1244 - In this beta version there is not yet a migration path from 1.2 (there
1245 will be one in the final 2.0 release)
1246 - A few significant changes are:
1248 - all commands are executed by a daemon (``ganeti-masterd``) and the
1249 various ``gnt-*`` commands are just front-ends to it
1250 - all the commands are entered into, and executed from a job queue,
1251 see the ``gnt-job(8)`` manpage
1252 - the RAPI daemon supports read-write operations, secured by basic
1253 HTTP authentication on top of HTTPS
1254 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1255 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1256 to migrate to DRBD 8 first while still running Ganeti 1.2)
1257 - DRBD devices are using statically allocated minor numbers, which
1258 will be assigned to existing instances during the migration process
1259 - there is support for both Xen PVM and Xen HVM instances running on
1261 - KVM virtualization is supported too
1262 - file-based storage has been implemented, which means that it is
1263 possible to run the cluster without LVM and DRBD storage, for
1264 example using a shared filesystem exported from shared storage (and
1265 still have live migration)
1271 *(Released Tue, 13 Jan 2009)*
1273 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1274 - Reuse the old instance mac address by default on instance import, if
1275 the instance name is the same.
1276 - Handle situations in which the node info rpc returns incomplete
1278 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1279 - Improved version of batcher:
1281 - state file support
1282 - instance mac address support
1283 - support for HVM clusters/instances
1285 - Add an option to show the number of cpu sockets and nodes in
1287 - Support OSes that handle more than one version of the OS api (but do
1288 not change the current API in any other way)
1289 - Fix ``gnt-node migrate``
1290 - ``gnt-debug`` man page
1291 - Fixes various more typos and small issues
1292 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1298 *(Released Wed, 24 Sep 2008)*
1300 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1301 type of disk exported to fully virtualized instances.
1302 - provide access to the serial console of HVM instances
1303 - instance auto_balance flag, set by default. If turned off it will
1304 avoid warnings on cluster verify if there is not enough memory to fail
1305 over an instance. in the future it will prevent automatically failing
1306 it over when we will support that.
1307 - batcher tool for instance creation, see ``tools/README.batcher``
1308 - ``gnt-instance reinstall --select-os`` to interactively select a new
1309 operating system when reinstalling an instance.
1310 - when changing the memory amount on instance modify a check has been
1311 added that the instance will be able to start. also warnings are
1312 emitted if the instance will not be able to fail over, if auto_balance
1314 - documentation fixes
1315 - sync fields between ``gnt-instance list/modify/add/import``
1316 - fix a race condition in drbd when the sync speed was set after giving
1317 the device a remote peer.
1323 *(Released Tue, 22 Jul 2008)*
1325 - note: the allowed size and number of tags per object were reduced
1326 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1327 - fixed twisted 8.x compatibility
1328 - fixed ``gnt-instance replace-disks`` with iallocator
1329 - add TCP keepalives on twisted connections to detect restarted nodes
1330 - disk increase support, see ``gnt-instance grow-disk``
1331 - implement bulk node/instance query for RAPI
1332 - add tags in node/instance listing (optional)
1333 - experimental migration (and live migration) support, read the man page
1334 for ``gnt-instance migrate``
1335 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1336 has some small improvements in handling its state file
1342 *(Released Fri, 13 Jun 2008)*
1344 - Experimental readonly, REST-based remote API implementation;
1345 automatically started on master node, TCP port 5080, if enabled by
1346 ``--enable-rapi`` parameter to configure script.
1347 - Instance allocator support. Add and import instance accept a
1348 ``--iallocator`` parameter, and call that instance allocator to decide
1349 which node to use for the instance. The iallocator document describes
1350 what's expected from an allocator script.
1351 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1352 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1353 node is lost there is still enough memory to fail over the instances
1355 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1356 ``gnt-cluster verify``, to check for site-specific compliance. All the
1357 hooks will run, and their output, if any, will be displayed. Any
1358 failing hook will make the verification return an error value.
1359 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1360 primary and secondary interfaces
1361 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1362 that is still declared as part of the cluster and has failed.
1363 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1364 specifying output fields, that just adds the chosen fields to the
1366 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1367 export from the filesystem.
1368 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1369 have been added. Using them you can enable/disable acpi and pae
1370 support, and specify a path for a cd image to be exported to the
1371 instance. These parameters as the name suggest only work on HVM
1373 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1374 PAE support will be set to the previously hardcoded values, but the
1375 (previously hardcoded) path to the CDROM ISO image will be unset and
1376 if required, needs to be set manually with ``gnt-instance modify``
1378 - The address to which an instance's VNC console is bound is now
1379 selectable per-instance, rather than being cluster wide. Of course
1380 this only applies to instances controlled via VNC, so currently just
1381 applies to HVM clusters.
1387 *(Released Mon, 18 Feb 2008)*
1389 - more tweaks to the disk activation code (especially helpful for DRBD)
1390 - change the default ``gnt-instance list`` output format, now there is
1391 one combined status field (see the manpage for the exact values this
1393 - some more fixes for the mac export to hooks change
1394 - make Ganeti not break with DRBD 8.2.x (which changed the version
1395 format in ``/proc/drbd``) (issue 24)
1396 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1397 template, allowing migration from DRBD0.7+MD to DRBD8
1403 *(Released Wed, 30 Jan 2008)*
1405 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1407 - add command aliases infrastructure and a few aliases
1408 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1409 man pages and the ``--help`` option of ``gnt-node
1410 list``/``gnt-instance list``
1411 - fix ``gnt-backup list`` with down nodes (issue 21)
1412 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1413 - fix the dist archive and add a check for including svn/git files in
1415 - some developer-related changes: improve the burnin and the QA suite,
1416 add an upload script for testing during development
1422 *(Released Wed, 16 Jan 2008)*
1424 - experimental HVM support, read the install document, section
1425 "Initializing the cluster"
1426 - allow for the PVM hypervisor per-instance kernel and initrd paths
1427 - add a new command ``gnt-cluster verify-disks`` which uses a new
1428 algorithm to improve the reconnection of the DRBD pairs if the device
1429 on the secondary node has gone away
1430 - make logical volume code auto-activate LVs at disk activation time
1431 - slightly improve the speed of activating disks
1432 - allow specification of the MAC address at instance creation time, and
1433 changing it later via ``gnt-instance modify``
1434 - fix handling of external commands that generate lots of output on
1436 - update documentation with regard to minimum version of DRBD8 supported
1442 *(Released Tue, 4 Dec 2007)*
1444 - Log the ``xm create`` output to the node daemon log on failure (to
1445 help diagnosing the error)
1446 - In debug mode, log all external commands output if failed to the logs
1447 - Change parsing of lvm commands to ignore stderr
1453 *(Released Wed, 28 Nov 2007)*
1455 - Another round of updates to the DRBD 8 code to deal with more failures
1456 in the replace secondary node operation
1457 - Some more logging of failures in disk operations (lvm, drbd)
1458 - A few documentation updates
1465 *(Released Tue, 13 Nov 2007)*
1467 - Change configuration file format from Python's Pickle to JSON.
1468 Upgrading is possible using the cfgupgrade utility.
1469 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1470 faster replace disks and is more stable (DRBD 8 has many improvements
1471 compared to DRBD 0.7)
1472 - Added command line tags support (see man pages for ``gnt-instance``,
1473 ``gnt-node``, ``gnt-cluster``)
1474 - Added instance rename support
1475 - Added multi-instance startup/shutdown
1476 - Added cluster rename support
1477 - Added ``gnt-node evacuate`` to simplify some node operations
1478 - Added instance reboot operation that can speedup reboot as compared to
1480 - Soften the requirement that hostnames are in FQDN format
1481 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1483 - Removed dependency on debian's patched fping that uses the
1484 non-standard ``-S`` option
1485 - Now the OS definitions are searched for in multiple, configurable
1486 paths (easier for distros to package)
1487 - Some changes to the hooks infrastructure (especially the new
1488 post-configuration update hook)
1489 - Other small bugfixes
