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
14 - The deprecated "bridge" nic parameter is no longer supported. Use
16 - Support for the undocumented and deprecated RAPI instance creation
17 request format version 0 has been dropped. Use version 1, supported
18 since Ganeti 2.1.3 and :doc:`documented <rapi>`, instead.
24 *(Released Mon, 07 Mar 2011)*
26 Final 2.4.0 release. Just a few small fixes:
28 - Fixed RAPI node evacuate
29 - Fixed the kvm-ifup script
30 - Fixed internal error handling for special job cases
31 - Updated man page to specify the escaping feature for options
37 *(Released Mon, 28 Feb 2011)*
39 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
40 that this feature wiped the disks of the wrong instance, leading to loss
45 - Fixed title of query field containing instance name
46 - Expanded the glossary in the documentation
47 - Fixed one unittest (internal issue)
53 *(Released Mon, 21 Feb 2011)*
55 A number of bug fixes plus just a couple functionality changes.
57 On the user-visible side, the ``gnt-* list`` command output has changed
58 with respect to "special" field states. The current rc1 style of display
59 can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
60 the default output mode special fields states are displayed as follows:
62 - Offline resource: ``*``
63 - Unavailable/not applicable: ``-``
64 - Data missing (RPC failure): ``?``
65 - Unknown field: ``??``
67 Another user-visible change is the addition of ``--force-join`` to
72 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
73 - Fixed regression in RAPI/instance reinstall where all parameters were
74 required (instead of optional)
75 - Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
76 - Fixed iallocator usage (offline nodes were not considered offline)
77 - Fixed ``gnt-node list`` with respect to non-vm_capable nodes
78 - Fixed hypervisor and OS parameter validation with respect to
80 - Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
82 - Fixed ``tools/listrunner`` with respect to agent-based usage
88 *(Released Fri, 4 Feb 2011)*
90 Many changes and fixes since the beta1 release. While there were some
91 internal changes, the code has been mostly stabilised for the RC
94 Note: the dumb allocator was removed in this release, as it was not kept
95 up-to-date with the IAllocator protocol changes. It is recommended to
96 use the ``hail`` command from the ganeti-htools package.
98 Note: the 2.4 and up versions of Ganeti are not compatible with the
99 0.2.x branch of ganeti-htools. You need to upgrade to
100 ganeti-htools-0.3.0 (or later).
102 Regressions fixed from 2.3
103 ~~~~~~~~~~~~~~~~~~~~~~~~~~
105 - Fixed the ``gnt-cluster verify-disks`` command

109 - Fixed wrong headers in instance listing for field aliases
114 - Fixed corner case in KVM handling of NICs
115 - Fixed many cases of wrong handling of non-vm_capable nodes
116 - Fixed a bug where a missing instance symlink was not possible to

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

130 - a few fixes to the cluster-merge tool, but it still cannot merge
131 multi-node groups (currently it is not recommended to use this tool)
137 - Improved network configuration for the KVM hypervisor
138 - Added e1000 as a supported NIC for Xen-HVM
139 - Improved the lvmstrap tool to also be able to use partitions, as
140 opposed to full disks
141 - Improved speed of disk wiping (the cluster parameter
142 ``prealloc_wipe_disks``, so that it has a low impact on the total time
143 of instance creations
144 - Added documentation for the OS parameters
145 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
146 hypervisor is not responding
147 - Added display of blacklisted and hidden OS information in
149 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
150 NIC and node parameters, which might create problems with currently
151 invalid (but undetected) configuration files, but prevents validation
152 failures when unrelated parameters are modified
153 - Changed cluster initialisation to wait for the master daemon to become
155 - Expanded the RAPI interface:
157 - Added config redistribution resource
158 - Added activation/deactivation of instance disks
159 - Added export of console information
161 - Implemented log file reopening on SIGHUP, which allows using
162 logrotate(8) for the Ganeti log files
163 - Added a basic OOB helper script as an example

192 - ``gnt-instance list-fields``
194 - Updated documentation and man pages
199 - Moved ``rapi_users`` file into separate directory, now named
200 ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
202 - Added new tool for running commands on many machines,
203 ``tools/ganeti-listrunner``
204 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also

209 - Added script to gracefully power off KVM instances
210 - Split ``utils`` module into smaller parts
211 - Changed query operations to return more detailed information, e.g.
212 whether an information is unavailable due to an offline node. To use
213 this new functionality, the LUXI call ``Query`` must be used. Field
214 information is now stored by the master daemon and can be retrieved
215 using ``QueryFields``. Instances, nodes and groups can also be queried
216 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
217 exposed via RAPI). The following commands make use of this
218 infrastructure change:
221 - ``gnt-group list-fields``

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

438 locks is expected for a later 2.2.x release
439 - Fixed dry-run behaviour with many commands
440 - Support ``ssh-agent`` again when adding nodes
441 - Many additional bugfixes
447 *(Released Fri, 30 Jul 2010)*
449 Important change: the internal RPC mechanism between Ganeti nodes has
450 changed from using a home-grown http library (based on the Python base
451 libraries) to use the PycURL library. This requires that PycURL is
452 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
453 against GnuTLS by default. cURL's support for GnuTLS had known issues
454 before cURL 7.21.0 and we recommend using the latest cURL release or
455 linking against OpenSSL. Most other distributions already link PycURL
456 and cURL against OpenSSL. The command::
458 python -c 'import pycurl; print pycurl.version'
460 can be used to determine the libraries PycURL and cURL are linked
463 Other significant changes:
465 - Rewrote much of the internals of the job queue, in order to achieve
466 better parallelism; this decouples job query operations from the job
467 processing, and it should allow much nicer behaviour of the master
468 daemon under load, and it also has uncovered some long-standing bugs
469 related to the job serialisation (now fixed)
470 - Added a default iallocator setting to the cluster parameters,
471 eliminating the need to always pass nodes or an iallocator for
472 operations that require selection of new node(s)
473 - Added experimental support for the LXC virtualization method
474 - Added support for OS parameters, which allows the installation of
475 instances to pass parameter to OS scripts in order to customise the
477 - Added a hypervisor parameter controlling the migration type (live or
478 non-live), since hypervisors have various levels of reliability; this
479 has renamed the 'live' parameter to 'mode'
480 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
481 logical volumes, meaning that cluster verify will ignore them and not
482 flag their presence as errors
483 - The watcher will now reset the error count for failed instances after
484 8 hours, thus allowing self-healing if the problem that caused the
485 instances to be down/fail to start has cleared in the meantime
486 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
487 check for, and warn, if the drbd module parameter ``usermode_helper``
488 is not consistent with the cluster-wide setting; this is needed to
489 make diagnose easier of failed drbd creations
490 - Started adding base IPv6 support, but this is not yet
491 enabled/available for use
492 - Rename operations (cluster, instance) will now return the new name,
493 which is especially useful if a short name was passed in
494 - Added support for instance migration in RAPI
495 - Added a tool to pre-configure nodes for the SSH setup, before joining
496 them to the cluster; this will allow in the future a simplified model
497 for node joining (but not yet fully enabled in 2.2); this needs the
498 paramiko python library
499 - Fixed handling of name-resolving errors
500 - Fixed consistency of job results on the error path
501 - Fixed master-failover race condition when executed multiple times in
503 - Fixed many bugs related to the job queue (mostly introduced during the
504 2.2 development cycle, so not all are impacting 2.1)
505 - Fixed instance migration with missing disk symlinks
506 - Fixed handling of unknown jobs in ``gnt-job archive``
507 - And many other small fixes/improvements
511 - Enhanced both the unittest and the QA coverage
512 - Switched the opcode validation to a generic model, and extended the
513 validation to all opcode parameters
514 - Changed more parts of the code that write shell scripts to use the
516 - Switched the master daemon to use the asyncore library for the Luxi
523 *(Released Thu, 17 Jun 2010)*
525 - Added tool (``move-instance``) and infrastructure to move instances
526 between separate clusters (see :doc:`separate documentation
527 <move-instance>` and :doc:`design document <design-2.2>`)
528 - Added per-request RPC timeout
529 - RAPI now requires a Content-Type header for requests with a body (e.g.
530 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
531 :rfc:`2616` (HTTP/1.1), section 7.2.1)
532 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
534 - Implemented initial support for running Ganeti daemons as separate
535 users, see configure-time flags ``--with-user-prefix`` and
536 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
538 - Instances can be removed after export (``gnt-backup export
540 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
541 key (instead of 1024 bit)
542 - Added new cluster configuration file for cluster domain secret
543 - Import/export now use SSL instead of SSH
544 - Added support for showing estimated time when exporting an instance,
545 see the ``ganeti-os-interface(7)`` manpage and look for
552 *(Released Tue, 16 Nov 2010)*
554 Some more bugfixes. Unless critical bugs occur, this will be the last
557 - Fix case of MAC special-values
558 - Fix mac checker regex
559 - backend: Fix typo causing "out of range" error
560 - Add missing --units in gnt-instance list man page
566 *(Released Tue, 24 Aug 2010)*
569 - Don't ignore secondary node silently on non-mirrored disk templates
571 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
572 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
573 - Properly document the usb_mouse parameter
574 - Fix path in ganeti-rapi(8) (issue 116)
575 - Adjust error message when the ganeti user's .ssh directory is
577 - Add same-node-check when changing the disk template to drbd
583 *(Released Fri, 16 Jul 2010)*
586 - Add an option to only select some reboot types during qa/burnin.
587 (on some hypervisors consequent reboots are not supported)
588 - Fix infrequent race condition in master failover. Sometimes the old
589 master ip address would be still detected as up for a short time
590 after it was removed, causing failover to fail.
591 - Decrease mlockall warnings when the ctypes module is missing. On
592 Python 2.4 we support running even if no ctypes module is installed,
593 but we were too verbose about this issue.
594 - Fix building on old distributions, on which man doesn't have a
596 - Fix RAPI not to ignore the MAC address on instance creation
597 - Implement the old instance creation format in the RAPI client.
603 *(Released Thu, 01 Jul 2010)*
605 A small bugfix release:
606 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
607 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
608 a non-existing option
609 - Fix instance create: the --force-variant option was ignored
610 - Improve pylint 0.21 compatibility and warnings with Python 2.6
611 - Fix modify node storage with non-FQDN arguments
612 - Fix RAPI client to authenticate under Python 2.6 when used
613 for more than 5 requests needing authentication
614 - Fix gnt-instance modify -t (storage) giving a wrong error message
615 when converting a non-shutdown drbd instance to plain
621 *(Released Fri, 18 Jun 2010)*
623 A small bugfix release:
625 - Fix live migration of KVM instances started with older Ganeti
626 versions which had fewer hypervisor parameters
627 - Fix gnt-instance grow-disk on down instances
628 - Fix an error-reporting bug during instance migration
629 - Better checking of the ``--net`` and ``--disk`` values, to avoid
630 silently ignoring broken ones
631 - Fix an RPC error reporting bug affecting, for example, RAPI client
633 - Fix bug triggered by different API version os-es on different nodes
634 - Fix a bug in instance startup with custom hvparams: OS level
635 parameters would fail to be applied.
636 - Fix the RAPI client under Python 2.6 (but more work is needed to
637 make it work completely well with OpenSSL)
638 - Fix handling of errors when resolving names from DNS
644 *(Released Thu, 3 Jun 2010)*
646 A medium sized development cycle. Some new features, and some
647 fixes/small improvements/cleanups.
652 The node deamon now tries to mlock itself into memory, unless the
653 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
654 its logs, and falls back to console logging. This allows emergency
655 features such as ``gnt-node powercycle`` to work even in the event of a
656 broken node disk (tested offlining the disk hosting the node's
657 filesystem and dropping its memory caches; don't try this at home)
659 KVM: add vhost-net acceleration support. It can be tested with a new
660 enough version of the kernel and of qemu-kvm.
662 KVM: Add instance chrooting feature. If you use privilege dropping for
663 your VMs you can also now force them to chroot to an empty directory,
664 before starting the emulated guest.
666 KVM: Add maximum migration bandwith and maximum downtime tweaking
667 support (requires a new-enough version of qemu-kvm).
669 Cluster verify will now warn if the master node doesn't have the master
672 Add a new (incompatible) instance creation request format to RAPI which
673 supports all parameters (previously only a subset was supported, and it
674 wasn't possible to extend the old format to accomodate all the new
675 features. The old format is still supported, and a client can check for
676 this feature, before using it, by checking for its presence in the
677 ``features`` RAPI resource.
679 Now with ancient latin support. Try it passing the ``--roman`` option to
680 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
681 (requires the python-roman module to be installed, in order to work).
686 As usual many internal code refactorings, documentation updates, and
689 - Lots of improvements and cleanups to the experimental Remote API
690 (RAPI) client library.
691 - A new unit test suite for the core daemon libraries.
692 - A fix to creating missing directories makes sure the umask is not
693 applied anymore. This enforces the same directory permissions
695 - Better handling terminating daemons with ctrl+c (used when running
696 them in debugging mode).
697 - Fix a race condition in live migrating a KVM instance, when stat()
698 on the old proc status file returned EINVAL, which is an unexpected
700 - Fixed manpage checking with newer man and utf-8 charachters. But now
701 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
707 *(Released Fri, 7 May 2010)*
709 Fix a bug which prevented untagged KVM instances from starting.
715 *(Released Fri, 7 May 2010)*
717 Another release with a long development cycle, during which many
718 different features were added.
723 The KVM hypervisor now can run the individual instances as non-root, to
724 reduce the impact of a VM being hijacked due to bugs in the
725 hypervisor. It is possible to run all instances as a single (non-root)
726 user, to manually specify a user for each instance, or to dynamically
727 allocate a user out of a cluster-wide pool to each instance, with the
728 guarantee that no two instances will run under the same user ID on any
731 An experimental RAPI client library, that can be used standalone
732 (without the other Ganeti libraries), is provided in the source tree as
733 ``lib/rapi/client.py``. Note this client might change its interface in
734 the future, as we iterate on its capabilities.
736 A new command, ``gnt-cluster renew-crypto`` has been added to easily
737 replace the cluster's certificates and crypto keys. This might help in
738 case they have been compromised, or have simply expired.
740 A new disk option for instance creation has been added that allows one
741 to "adopt" currently existing logical volumes, with data
742 preservation. This should allow easier migration to Ganeti from
743 unmanaged (or managed via other software) instances.
745 Another disk improvement is the possibility to convert between redundant
746 (DRBD) and plain (LVM) disk configuration for an instance. This should
747 allow better scalability (starting with one node and growing the
748 cluster, or shrinking a two-node cluster to one node).
750 A new feature that could help with automated node failovers has been
751 implemented: if a node sees itself as offline (by querying the master
752 candidates), it will try to shutdown (hard) all instances and any active
753 DRBD devices. This reduces the risk of duplicate instances if an
754 external script automatically failovers the instances on such nodes. To
755 enable this, the cluster parameter ``maintain_node_health`` should be
756 enabled; in the future this option (per the name) will enable other
757 automatic maintenance features.
759 Instance export/import now will reuse the original instance
760 specifications for all parameters; that means exporting an instance,
761 deleting it and the importing it back should give an almost identical
762 instance. Note that the default import behaviour has changed from
763 before, where it created only one NIC; now it recreates the original
766 Cluster verify has added a few new checks: SSL certificates validity,
767 /etc/hosts consistency across the cluster, etc.
772 As usual, many internal changes were done, documentation fixes,
775 - Fixed cluster initialization with disabled cluster storage (regression
777 - File-based storage supports growing the disks
778 - Fixed behaviour of node role changes
779 - Fixed cluster verify for some corner cases, plus a general rewrite of
780 cluster verify to allow future extension with more checks
781 - Fixed log spamming by watcher and node daemon (regression introduced
783 - Fixed possible validation issues when changing the list of enabled
785 - Fixed cleanup of /etc/hosts during node removal
786 - Fixed RAPI response for invalid methods
787 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
788 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
789 from ide disks, etc.)
790 - Allow OS changes without re-installation (to record a changed OS
791 outside of Ganeti, or to allow OS renames)
792 - Allow instance creation without OS installation (useful for example if
793 the OS will be installed manually, or restored from a backup not in
795 - Implemented option to make cluster ``copyfile`` use the replication
797 - Added list of enabled hypervisors to ssconf (possibly useful for
799 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
801 - A partial form of node re-IP is possible via node readd, which now
802 allows changed node primary IP
803 - Command line utilities now show an informational message if the job is
805 - The logs of the master daemon now show the PID/UID/GID of the
812 *(Released Fri, 12 Mar 2010)*
814 During the 2.1.0 long release candidate cycle, a lot of improvements and
815 changes have accumulated with were released later as 2.1.1.
820 The node evacuate command (``gnt-node evacuate``) was significantly
821 rewritten, and as such the IAllocator protocol was changed - a new
822 request type has been added. This unfortunate change during a stable
823 series is designed to improve performance of node evacuations; on
824 clusters with more than about five nodes and which are well-balanced,
825 evacuation should proceed in parallel for all instances of the node
826 being evacuated. As such, any existing IAllocator scripts need to be
827 updated, otherwise the above command will fail due to the unknown
828 request. The provided "dumb" allocator has not been updated; but the
829 ganeti-htools package supports the new protocol since version 0.2.4.
831 Another important change is increased validation of node and instance
832 names. This might create problems in special cases, if invalid host
833 names are being used.
835 Also, a new layer of hypervisor parameters has been added, that sits at
836 OS level between the cluster defaults and the instance ones. This allows
837 customisation of virtualization parameters depending on the installed
838 OS. For example instances with OS 'X' may have a different KVM kernel
839 (or any other parameter) than the cluster defaults. This is intended to
840 help managing a multiple OSes on the same cluster, without manual
841 modification of each instance's parameters.
843 A tool for merging clusters, ``cluster-merge``, has been added in the
849 - Improved the int/float conversions that should make the code more
850 robust in face of errors from the node daemons
851 - Fixed the remove node code in case of internal configuration errors
852 - Fixed the node daemon behaviour in face of inconsistent queue
853 directory (e.g. read-only file-system where we can't open the files
855 - Fixed the behaviour of gnt-node modify for master candidate demotion;
856 now it either aborts cleanly or, if given the new "auto_promote"
857 parameter, will automatically promote other nodes as needed
858 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
859 completely prevent Ganeti from working
860 - Fixed bug for instance export when not all disks were successfully
862 - Fixed behaviour of node add when the new node is slow in starting up
864 - Fixed handling of signals in the LUXI client, which should improve
865 behaviour of command-line scripts
866 - Added checks for invalid node/instance names in the configuration (now
867 flagged during cluster verify)
868 - Fixed watcher behaviour for disk activation errors
869 - Fixed two potentially endless loops in http library, which led to the
870 RAPI daemon hanging and consuming 100% CPU in some cases
871 - Fixed bug in RAPI daemon related to hashed passwords
872 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
874 - Enhanced compatibility with non-Debian OSes, but not using absolute
875 path in some commands and allowing customisation of the ssh
876 configuration directory
877 - Fixed possible future issue with new Python versions by abiding to the
878 proper use of ``__slots__`` attribute on classes
879 - Added checks that should prevent directory traversal attacks
880 - Many documentation fixes based on feedback from users
885 - Added an "early_release" more for instance replace disks and node
886 evacuate, where we release locks earlier and thus allow higher
887 parallelism within the cluster
888 - Added watcher hooks, intended to allow the watcher to restart other
889 daemons (e.g. from the ganeti-nbma project), but they can be used of
890 course for any other purpose
891 - Added a compile-time disable for DRBD barriers, to increase
892 performance if the administrator trusts the power supply or the
893 storage system to not lose writes
894 - Added the option of using syslog for logging instead of, or in
895 addition to, Ganeti's own log files
896 - Removed boot restriction for paravirtual NICs for KVM, recent versions
897 can indeed boot from a paravirtual NIC
898 - Added a generic debug level for many operations; while this is not
899 used widely yet, it allows one to pass the debug value all the way to
901 - Enhanced the hooks environment for instance moves (failovers,
902 migrations) where the primary/secondary nodes changed during the
903 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
904 - Enhanced data validations for many user-supplied values; one important
905 item is the restrictions imposed on instance and node names, which
906 might reject some (invalid) host names
907 - Add a configure-time option to disable file-based storage, if it's not
908 needed; this allows greater security separation between the master
909 node and the other nodes from the point of view of the inter-node RPC
911 - Added user notification in interactive tools if job is waiting in the
912 job queue or trying to acquire locks
913 - Added log messages when a job is waiting for locks
914 - Added filtering by node tags in instance operations which admit
915 multiple instances (start, stop, reboot, reinstall)
916 - Added a new tool for cluster mergers, ``cluster-merge``
917 - Parameters from command line which are of the form ``a=b,c=d`` can now
918 use backslash escapes to pass in values which contain commas,
919 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
921 - For KVM, the instance name is the first parameter passed to KVM, so
922 that it's more visible in the process list
928 *(Released Tue, 2 Mar 2010)*
930 Ganeti 2.1 brings many improvements with it. Major changes:
932 - Added infrastructure to ease automated disk repairs
933 - Added new daemon to export configuration data in a cheaper way than
935 - Instance NICs can now be routed instead of being associated with a
937 - Improved job locking logic to reduce impact of jobs acquiring multiple
938 locks waiting for other long-running jobs
940 In-depth implementation details can be found in the Ganeti 2.1 design
946 - Added chroot hypervisor
947 - Added more options to xen-hvm hypervisor (``kernel_path`` and
949 - Added more options to xen-pvm hypervisor (``use_bootloader``,
950 ``bootloader_path`` and ``bootloader_args``)
951 - Added the ``use_localtime`` option for the xen-hvm and kvm
952 hypervisors, and the default value for this has changed to false (in
953 2.0 xen-hvm always enabled it)
954 - Added luxi call to submit multiple jobs in one go
955 - Added cluster initialization option to not modify ``/etc/hosts``
957 - Added network interface parameters
958 - Added dry run mode to some LUs
959 - Added RAPI resources:
961 - ``/2/instances/[instance_name]/info``

966 - ``/2/nodes/[node_name]/storage``
967 - ``/2/nodes/[node_name]/storage/modify``
968 - ``/2/nodes/[node_name]/storage/repair``
970 - Added OpCodes to evacuate or migrate all instances on a node
971 - Added new command to list storage elements on nodes (``gnt-node
972 list-storage``) and modify them (``gnt-node modify-storage``)
973 - Added new ssconf files with master candidate IP address
974 (``ssconf_master_candidates_ips``), node primary IP address
975 (``ssconf_node_primary_ips``) and node secondary IP address
976 (``ssconf_node_secondary_ips``)
977 - Added ``ganeti-confd`` and a client library to query the Ganeti
978 configuration via UDP
979 - Added ability to run hooks after cluster initialization and before
981 - Added automatic mode for disk replace (``gnt-instance replace-disks

990 - Added new job status field ``lock_status``
991 - Added parseable error codes to cluster verification (``gnt-cluster
992 verify --error-codes``) and made output less verbose (use
993 ``--verbose`` to restore previous behaviour)
994 - Added UUIDs to the main config entities (cluster, nodes, instances)
995 - Added support for OS variants
996 - Added support for hashed passwords in the Ganeti remote API users file
998 - Added option to specify maximum timeout on instance shutdown
999 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
1000 - Added new helper script to start and stop Ganeti daemons
1001 (``daemon-util``), with the intent to reduce the work necessary to
1002 adjust Ganeti for non-Debian distributions and to start/stop daemons
1004 - Added more unittests
1005 - Fixed critical bug in ganeti-masterd startup
1006 - Removed the configure-time ``kvm-migration-port`` parameter, this is
1007 now customisable at the cluster level for both the KVM and Xen
1008 hypervisors using the new ``migration_port`` parameter
1009 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
1010 reinstalling an instance
1011 - Allowed ``@`` in tag names

1033 - Improve safety of the code in some error paths
1034 - Improve data validation in the master of values returned from nodes
1040 *(Released Thu, 17 Dec 2009)*
1042 - Fix security issue due to missing validation of iallocator names; this
1043 allows local and remote execution of arbitrary executables
1044 - Fix failure of gnt-node list during instance removal
1045 - Ship the RAPI documentation in the archive
1051 *(Released Wed, 30 Sep 2009)*
1053 - Fixed many wrong messages
1054 - Fixed a few bugs related to the locking library
1055 - Fixed MAC checking at instance creation time
1056 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1057 - Fixed a few issues related to signal handling in both daemons and
1059 - Fixed the example startup script provided
1060 - Fixed insserv dependencies in the example startup script (patch from
1062 - Fixed handling of drained nodes in the iallocator framework
1063 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1065 - Fixed error related to invalid job IDs in job polling
1066 - Fixed job/opcode persistence on unclean master shutdown
1067 - Fixed handling of partial job processing after unclean master
1069 - Fixed error reporting from LUs, previously all errors were converted
1070 into execution errors
1071 - Fixed error reporting from burnin
1072 - Decreased significantly the memory usage of the job queue
1073 - Optimised slightly multi-job submission
1074 - Optimised slightly opcode loading
1075 - Backported the multi-job submit framework from the development
1076 branch; multi-instance start and stop should be faster
1077 - Added script to clean archived jobs after 21 days; this will reduce
1078 the size of the queue directory
1079 - Added some extra checks in disk size tracking
1080 - Added an example ethers hook script
1081 - Added a cluster parameter that prevents Ganeti from modifying of
1083 - Added more node information to RAPI responses
1084 - Added a ``gnt-job watch`` command that allows following the ouput of a
1086 - Added a bind-address option to ganeti-rapi
1087 - Added more checks to the configuration verify
1088 - Enhanced the burnin script such that some operations can be retried
1090 - Converted instance reinstall to multi-instance model
1096 *(Released Fri, 7 Aug 2009)*
1098 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1099 to allow using the pre-2.0.2 behaviour in activation, if any existing
1100 instances have mismatched disk sizes in the configuration
1101 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1102 any configuration mismatches for disk sizes
1103 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1104 failover to work on two-node clusters
1105 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1107 - Fixed detection of OS script errors in ``gnt-backup export``
1108 - Fixed exit code of ``gnt-backup export``
1114 *(Released Fri, 17 Jul 2009)*
1116 - Added experimental support for stripped logical volumes; this should
1117 enhance performance but comes with a higher complexity in the block
1118 device handling; stripping is only enabled when passing
1119 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1120 affected even in the non-stripped mode
1121 - Improved resiliency against transient failures at the end of DRBD
1122 resyncs, and in general of DRBD resync checks
1123 - Fixed a couple of issues with exports and snapshot errors
1124 - Fixed a couple of issues in instance listing
1125 - Added display of the disk size in ``gnt-instance info``
1126 - Fixed checking for valid OSes in instance creation
1127 - Fixed handling of the "vcpus" parameter in instance listing and in
1128 general of invalid parameters
1129 - Fixed http server library, and thus RAPI, to handle invalid
1130 username/password combinations correctly; this means that now they
1131 report unauthorized for queries too, not only for modifications,
1132 allowing earlier detect of configuration problems
1133 - Added a new "role" node list field, equivalent to the master/master
1134 candidate/drained/offline flags combinations
1135 - Fixed cluster modify and changes of candidate pool size
1136 - Fixed cluster verify error messages for wrong files on regular nodes
1137 - Fixed a couple of issues with node demotion from master candidate role
1138 - Fixed node readd issues
1139 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1140 - Added a new ``--no-voting`` option for masterfailover to fix failover
1141 on two-nodes clusters when the former master node is unreachable
1142 - Added instance reinstall over RAPI
1148 *(Released Tue, 16 Jun 2009)*
1150 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1151 allow re-adding the start in single-user option (regression from 1.2)
1152 - the watcher writes the instance status to a file, to allow monitoring
1153 to report the instance status (from the master) based on cached
1154 results of the watcher's queries; while this can get stale if the
1155 watcher is being locked due to other work on the cluster, this is
1156 still an improvement
1157 - the watcher now also restarts the node daemon and the rapi daemon if
1159 - fixed the watcher to handle full and drained queue cases
1160 - hooks export more instance data in the environment, which helps if
1161 hook scripts need to take action based on the instance's properties
1162 (no longer need to query back into ganeti)
1163 - instance failovers when the instance is stopped do not check for free
1164 RAM, so that failing over a stopped instance is possible in low memory
1166 - rapi uses queries for tags instead of jobs (for less job traffic), and
1167 for cluster tags it won't talk to masterd at all but read them from
1169 - a couple of error handling fixes in RAPI
1170 - drbd handling: improved the error handling of inconsistent disks after
1171 resync to reduce the frequency of "there are some degraded disks for
1172 this instance" messages
1173 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1174 error handling path called a wrong function name)
1180 *(Released Wed, 27 May 2009)*
1182 - no changes from rc5
1185 Version 2.0 release candidate 5
1186 -------------------------------

1191 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1192 - some small improvements to RAPI and IAllocator
1193 - make watcher automatically start the master daemon if down
1196 Version 2.0 release candidate 4
1197 -------------------------------
1199 *(Released Mon, 27 Apr 2009)*
1201 - change the OS list to not require locks; this helps with big clusters
1202 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1203 volume group is broken
1204 - ``gnt-instance info``, without any arguments, doesn't run for all
1205 instances anymore; either pass ``--all`` or pass the desired
1206 instances; this helps against mistakes on big clusters where listing
1207 the information for all instances takes a long time
1208 - miscellaneous doc and man pages fixes
1211 Version 2.0 release candidate 3
1212 -------------------------------
1214 *(Released Wed, 8 Apr 2009)*
1216 - Change the internal locking model of some ``gnt-node`` commands, in
1217 order to reduce contention (and blocking of master daemon) when
1218 batching many creation/reinstall jobs
1219 - Fixes to Xen soft reboot
1220 - No longer build documentation at build time, instead distribute it in
1221 the archive, in order to reduce the need for the whole docbook/rst
1225 Version 2.0 release candidate 2
1226 -------------------------------
1228 *(Released Fri, 27 Mar 2009)*
1230 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1231 - Fix watcher startup sequence, improves the behaviour of busy clusters
1232 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1233 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1234 bind address and other places
1235 - Some documentation fixes and updates
1238 Version 2.0 release candidate 1
1239 -------------------------------
1241 *(Released Mon, 2 Mar 2009)*
1243 - More documentation updates, now all docs should be more-or-less
1245 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1247 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1249 - Fix an issue related to $libdir/run/ganeti and cluster creation
1255 *(Released Thu, 19 Feb 2009)*
1257 - Xen PVM and KVM have switched the default value for the instance root
1258 disk to the first partition on the first drive, instead of the whole
1259 drive; this means that the OS installation scripts must be changed
1261 - Man pages have been updated
1262 - RAPI has been switched by default to HTTPS, and the exported functions
1263 should all work correctly
1264 - RAPI v1 has been removed
1265 - Many improvements to the KVM hypervisor
1266 - Block device errors are now better reported
1267 - Many other bugfixes and small improvements
1273 *(Released Mon, 26 Jan 2009)*
1275 - Version 2 is a general rewrite of the code and therefore the
1276 differences are too many to list, see the design document for 2.0 in
1277 the ``doc/`` subdirectory for more details
1278 - In this beta version there is not yet a migration path from 1.2 (there
1279 will be one in the final 2.0 release)
1280 - A few significant changes are:
1282 - all commands are executed by a daemon (``ganeti-masterd``) and the
1283 various ``gnt-*`` commands are just front-ends to it
1284 - all the commands are entered into, and executed from a job queue,
1285 see the ``gnt-job(8)`` manpage
1286 - the RAPI daemon supports read-write operations, secured by basic
1287 HTTP authentication on top of HTTPS
1288 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1289 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1290 to migrate to DRBD 8 first while still running Ganeti 1.2)
1291 - DRBD devices are using statically allocated minor numbers, which
1292 will be assigned to existing instances during the migration process
1293 - there is support for both Xen PVM and Xen HVM instances running on
1295 - KVM virtualization is supported too
1296 - file-based storage has been implemented, which means that it is
1297 possible to run the cluster without LVM and DRBD storage, for
1298 example using a shared filesystem exported from shared storage (and
1299 still have live migration)
1305 *(Released Tue, 13 Jan 2009)*
1307 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1308 - Reuse the old instance mac address by default on instance import, if
1309 the instance name is the same.
1310 - Handle situations in which the node info rpc returns incomplete
1312 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1313 - Improved version of batcher:
1315 - state file support
1316 - instance mac address support
1317 - support for HVM clusters/instances
1319 - Add an option to show the number of cpu sockets and nodes in
1321 - Support OSes that handle more than one version of the OS api (but do
1322 not change the current API in any other way)
1323 - Fix ``gnt-node migrate``
1324 - ``gnt-debug`` man page
1325 - Fixes various more typos and small issues
1326 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1332 *(Released Wed, 24 Sep 2008)*
1334 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1335 type of disk exported to fully virtualized instances.
1336 - provide access to the serial console of HVM instances
1337 - instance auto_balance flag, set by default. If turned off it will
1338 avoid warnings on cluster verify if there is not enough memory to fail
1339 over an instance. in the future it will prevent automatically failing
1340 it over when we will support that.
1341 - batcher tool for instance creation, see ``tools/README.batcher``
1342 - ``gnt-instance reinstall --select-os`` to interactively select a new
1343 operating system when reinstalling an instance.
1344 - when changing the memory amount on instance modify a check has been
1345 added that the instance will be able to start. also warnings are
1346 emitted if the instance will not be able to fail over, if auto_balance
1348 - documentation fixes
1349 - sync fields between ``gnt-instance list/modify/add/import``
1350 - fix a race condition in drbd when the sync speed was set after giving
1351 the device a remote peer.
1357 *(Released Tue, 22 Jul 2008)*
1359 - note: the allowed size and number of tags per object were reduced
1360 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1361 - fixed twisted 8.x compatibility
1362 - fixed ``gnt-instance replace-disks`` with iallocator
1363 - add TCP keepalives on twisted connections to detect restarted nodes
1364 - disk increase support, see ``gnt-instance grow-disk``
1365 - implement bulk node/instance query for RAPI
1366 - add tags in node/instance listing (optional)
1367 - experimental migration (and live migration) support, read the man page
1368 for ``gnt-instance migrate``
1369 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1370 has some small improvements in handling its state file
1376 *(Released Fri, 13 Jun 2008)*
1378 - Experimental readonly, REST-based remote API implementation;
1379 automatically started on master node, TCP port 5080, if enabled by
1380 ``--enable-rapi`` parameter to configure script.
1381 - Instance allocator support. Add and import instance accept a
1382 ``--iallocator`` parameter, and call that instance allocator to decide
1383 which node to use for the instance. The iallocator document describes
1384 what's expected from an allocator script.
1385 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1386 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1387 node is lost there is still enough memory to fail over the instances
1389 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1390 ``gnt-cluster verify``, to check for site-specific compliance. All the
1391 hooks will run, and their output, if any, will be displayed. Any
1392 failing hook will make the verification return an error value.
1393 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1394 primary and secondary interfaces
1395 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1396 that is still declared as part of the cluster and has failed.
1397 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1398 specifying output fields, that just adds the chosen fields to the
1400 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1401 export from the filesystem.
1402 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1403 have been added. Using them you can enable/disable acpi and pae
1404 support, and specify a path for a cd image to be exported to the
1405 instance. These parameters as the name suggest only work on HVM
1407 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1408 PAE support will be set to the previously hardcoded values, but the
1409 (previously hardcoded) path to the CDROM ISO image will be unset and
1410 if required, needs to be set manually with ``gnt-instance modify``
1412 - The address to which an instance's VNC console is bound is now
1413 selectable per-instance, rather than being cluster wide. Of course
1414 this only applies to instances controlled via VNC, so currently just
1415 applies to HVM clusters.
1421 *(Released Mon, 18 Feb 2008)*
1423 - more tweaks to the disk activation code (especially helpful for DRBD)
1424 - change the default ``gnt-instance list`` output format, now there is
1425 one combined status field (see the manpage for the exact values this
1427 - some more fixes for the mac export to hooks change
1428 - make Ganeti not break with DRBD 8.2.x (which changed the version
1429 format in ``/proc/drbd``) (issue 24)
1430 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1431 template, allowing migration from DRBD0.7+MD to DRBD8
1437 *(Released Wed, 30 Jan 2008)*
1439 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1441 - add command aliases infrastructure and a few aliases
1442 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1443 man pages and the ``--help`` option of ``gnt-node
1444 list``/``gnt-instance list``
1445 - fix ``gnt-backup list`` with down nodes (issue 21)
1446 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1447 - fix the dist archive and add a check for including svn/git files in
1449 - some developer-related changes: improve the burnin and the QA suite,
1450 add an upload script for testing during development
1456 *(Released Wed, 16 Jan 2008)*
1458 - experimental HVM support, read the install document, section
1459 "Initializing the cluster"
1460 - allow for the PVM hypervisor per-instance kernel and initrd paths
1461 - add a new command ``gnt-cluster verify-disks`` which uses a new
1462 algorithm to improve the reconnection of the DRBD pairs if the device
1463 on the secondary node has gone away
1464 - make logical volume code auto-activate LVs at disk activation time
1465 - slightly improve the speed of activating disks
1466 - allow specification of the MAC address at instance creation time, and
1467 changing it later via ``gnt-instance modify``
1468 - fix handling of external commands that generate lots of output on
1470 - update documentation with regard to minimum version of DRBD8 supported
1476 *(Released Tue, 4 Dec 2007)*
1478 - Log the ``xm create`` output to the node daemon log on failure (to
1479 help diagnosing the error)
1480 - In debug mode, log all external commands output if failed to the logs
1481 - Change parsing of lvm commands to ignore stderr
1487 *(Released Wed, 28 Nov 2007)*
1489 - Another round of updates to the DRBD 8 code to deal with more failures
1490 in the replace secondary node operation
1491 - Some more logging of failures in disk operations (lvm, drbd)
1492 - A few documentation updates
1499 *(Released Tue, 13 Nov 2007)*
1501 - Change configuration file format from Python's Pickle to JSON.
1502 Upgrading is possible using the cfgupgrade utility.
1503 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1504 faster replace disks and is more stable (DRBD 8 has many improvements
1505 compared to DRBD 0.7)
1506 - Added command line tags support (see man pages for ``gnt-instance``,
1507 ``gnt-node``, ``gnt-cluster``)
1508 - Added instance rename support
1509 - Added multi-instance startup/shutdown
1510 - Added cluster rename support
1511 - Added ``gnt-node evacuate`` to simplify some node operations
1512 - Added instance reboot operation that can speedup reboot as compared to
1514 - Soften the requirement that hostnames are in FQDN format
1515 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1517 - Removed dependency on debian's patched fping that uses the
1518 non-standard ``-S`` option
1519 - Now the OS definitions are searched for in multiple, configurable
1520 paths (easier for distros to package)
1521 - Some changes to the hooks infrastructure (especially the new
1522 post-configuration update hook)
1523 - Other small bugfixes
