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
21 *(Released Mon, 07 Mar 2011)*
23 Final 2.4.0 release. Just a few small fixes:
25 - Fixed RAPI node evacuate
26 - Fixed the kvm-ifup script
27 - Fixed internal error handling for special job cases
28 - Updated man page to specify the escaping feature for options
34 *(Released Mon, 28 Feb 2011)*
36 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
37 that this feature wiped the disks of the wrong instance, leading to loss
42 - Fixed title of query field containing instance name
43 - Expanded the glossary in the documentation
44 - Fixed one unittest (internal issue)
50 *(Released Mon, 21 Feb 2011)*
52 A number of bug fixes plus just a couple functionality changes.
54 On the user-visible side, the ``gnt-* list`` command output has changed
55 with respect to "special" field states. The current rc1 style of display
56 can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
57 the default output mode special fields states are displayed as follows:
59 - Offline resource: ``*``
60 - Unavailable/not applicable: ``-``
61 - Data missing (RPC failure): ``?``
62 - Unknown field: ``??``
64 Another user-visible change is the addition of ``--force-join`` to
69 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
70 - Fixed regression in RAPI/instance reinstall where all parameters were
71 required (instead of optional)
72 - Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
73 - Fixed iallocator usage (offline nodes were not considered offline)
74 - Fixed ``gnt-node list`` with respect to non-vm_capable nodes
75 - Fixed hypervisor and OS parameter validation with respect to
77 - Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
79 - Fixed ``tools/listrunner`` with respect to agent-based usage
85 *(Released Fri, 4 Feb 2011)*
87 Many changes and fixes since the beta1 release. While there were some
88 internal changes, the code has been mostly stabilised for the RC
91 Note: the dumb allocator was removed in this release, as it was not kept
92 up-to-date with the IAllocator protocol changes. It is recommended to
93 use the ``hail`` command from the ganeti-htools package.
95 Note: the 2.4 and up versions of Ganeti are not compatible with the
96 0.2.x branch of ganeti-htools. You need to upgrade to
97 ganeti-htools-0.3.0 (or later).
99 Regressions fixed from 2.3

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

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

127 - a few fixes to the cluster-merge tool, but it still cannot merge
128 multi-node groups (currently it is not recommended to use this tool)
134 - Improved network configuration for the KVM hypervisor
135 - Added e1000 as a supported NIC for Xen-HVM
136 - Improved the lvmstrap tool to also be able to use partitions, as
137 opposed to full disks
138 - Improved speed of disk wiping (the cluster parameter
139 ``prealloc_wipe_disks``, so that it has a low impact on the total time
140 of instance creations
141 - Added documentation for the OS parameters
142 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
143 hypervisor is not responding
144 - Added display of blacklisted and hidden OS information in
146 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
147 NIC and node parameters, which might create problems with currently
148 invalid (but undetected) configuration files, but prevents validation
149 failures when unrelated parameters are modified
150 - Changed cluster initialisation to wait for the master daemon to become
152 - Expanded the RAPI interface:
154 - Added config redistribution resource
155 - Added activation/deactivation of instance disks
156 - Added export of console information
158 - Implemented log file reopening on SIGHUP, which allows using
159 logrotate(8) for the Ganeti log files
160 - Added a basic OOB helper script as an example
166 *(Released Fri, 14 Jan 2011)*

189 - ``gnt-instance list-fields``
191 - Updated documentation and man pages
196 - Moved ``rapi_users`` file into separate directory, now named

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

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

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

961 - ``/2/nodes/[node_name]/migrate``
962 - ``/2/nodes/[node_name]/role``
963 - ``/2/nodes/[node_name]/storage``
964 - ``/2/nodes/[node_name]/storage/modify``
965 - ``/2/nodes/[node_name]/storage/repair``
967 - Added OpCodes to evacuate or migrate all instances on a node
968 - Added new command to list storage elements on nodes (``gnt-node
969 list-storage``) and modify them (``gnt-node modify-storage``)
970 - Added new ssconf files with master candidate IP address
971 (``ssconf_master_candidates_ips``), node primary IP address
972 (``ssconf_node_primary_ips``) and node secondary IP address
973 (``ssconf_node_secondary_ips``)
974 - Added ``ganeti-confd`` and a client library to query the Ganeti
975 configuration via UDP
976 - Added ability to run hooks after cluster initialization and before
978 - Added automatic mode for disk replace (``gnt-instance replace-disks

987 - Added new job status field ``lock_status``
988 - Added parseable error codes to cluster verification (``gnt-cluster
989 verify --error-codes``) and made output less verbose (use
990 ``--verbose`` to restore previous behaviour)
991 - Added UUIDs to the main config entities (cluster, nodes, instances)
992 - Added support for OS variants
993 - Added support for hashed passwords in the Ganeti remote API users file
995 - Added option to specify maximum timeout on instance shutdown
996 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
997 - Added new helper script to start and stop Ganeti daemons
998 (``daemon-util``), with the intent to reduce the work necessary to
999 adjust Ganeti for non-Debian distributions and to start/stop daemons
1001 - Added more unittests
1002 - Fixed critical bug in ganeti-masterd startup
1003 - Removed the configure-time ``kvm-migration-port`` parameter, this is
1004 now customisable at the cluster level for both the KVM and Xen
1005 hypervisors using the new ``migration_port`` parameter
1006 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
1007 reinstalling an instance

1030 - Improve safety of the code in some error paths
1031 - Improve data validation in the master of values returned from nodes
1037 *(Released Thu, 17 Dec 2009)*
1039 - Fix security issue due to missing validation of iallocator names; this
1040 allows local and remote execution of arbitrary executables
1041 - Fix failure of gnt-node list during instance removal
1042 - Ship the RAPI documentation in the archive
1048 *(Released Wed, 30 Sep 2009)*
1050 - Fixed many wrong messages
1051 - Fixed a few bugs related to the locking library
1052 - Fixed MAC checking at instance creation time
1053 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1054 - Fixed a few issues related to signal handling in both daemons and
1056 - Fixed the example startup script provided
1057 - Fixed insserv dependencies in the example startup script (patch from
1059 - Fixed handling of drained nodes in the iallocator framework
1060 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1062 - Fixed error related to invalid job IDs in job polling
1063 - Fixed job/opcode persistence on unclean master shutdown
1064 - Fixed handling of partial job processing after unclean master
1066 - Fixed error reporting from LUs, previously all errors were converted
1067 into execution errors
1068 - Fixed error reporting from burnin
1069 - Decreased significantly the memory usage of the job queue
1070 - Optimised slightly multi-job submission
1071 - Optimised slightly opcode loading
1072 - Backported the multi-job submit framework from the development
1073 branch; multi-instance start and stop should be faster
1074 - Added script to clean archived jobs after 21 days; this will reduce
1075 the size of the queue directory
1076 - Added some extra checks in disk size tracking
1077 - Added an example ethers hook script
1078 - Added a cluster parameter that prevents Ganeti from modifying of
1080 - Added more node information to RAPI responses
1081 - Added a ``gnt-job watch`` command that allows following the ouput of a
1083 - Added a bind-address option to ganeti-rapi
1084 - Added more checks to the configuration verify
1085 - Enhanced the burnin script such that some operations can be retried
1087 - Converted instance reinstall to multi-instance model
1093 *(Released Fri, 7 Aug 2009)*
1095 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1096 to allow using the pre-2.0.2 behaviour in activation, if any existing
1097 instances have mismatched disk sizes in the configuration
1098 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1099 any configuration mismatches for disk sizes
1100 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1101 failover to work on two-node clusters
1102 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1104 - Fixed detection of OS script errors in ``gnt-backup export``
1105 - Fixed exit code of ``gnt-backup export``
1111 *(Released Fri, 17 Jul 2009)*
1113 - Added experimental support for stripped logical volumes; this should
1114 enhance performance but comes with a higher complexity in the block
1115 device handling; stripping is only enabled when passing
1116 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1117 affected even in the non-stripped mode
1118 - Improved resiliency against transient failures at the end of DRBD
1119 resyncs, and in general of DRBD resync checks
1120 - Fixed a couple of issues with exports and snapshot errors
1121 - Fixed a couple of issues in instance listing
1122 - Added display of the disk size in ``gnt-instance info``
1123 - Fixed checking for valid OSes in instance creation
1124 - Fixed handling of the "vcpus" parameter in instance listing and in
1125 general of invalid parameters
1126 - Fixed http server library, and thus RAPI, to handle invalid
1127 username/password combinations correctly; this means that now they
1128 report unauthorized for queries too, not only for modifications,
1129 allowing earlier detect of configuration problems
1130 - Added a new "role" node list field, equivalent to the master/master
1131 candidate/drained/offline flags combinations
1132 - Fixed cluster modify and changes of candidate pool size
1133 - Fixed cluster verify error messages for wrong files on regular nodes
1134 - Fixed a couple of issues with node demotion from master candidate role
1135 - Fixed node readd issues
1136 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1137 - Added a new ``--no-voting`` option for masterfailover to fix failover
1138 on two-nodes clusters when the former master node is unreachable
1139 - Added instance reinstall over RAPI
1145 *(Released Tue, 16 Jun 2009)*
1147 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1148 allow re-adding the start in single-user option (regression from 1.2)
1149 - the watcher writes the instance status to a file, to allow monitoring
1150 to report the instance status (from the master) based on cached
1151 results of the watcher's queries; while this can get stale if the
1152 watcher is being locked due to other work on the cluster, this is
1153 still an improvement
1154 - the watcher now also restarts the node daemon and the rapi daemon if
1156 - fixed the watcher to handle full and drained queue cases
1157 - hooks export more instance data in the environment, which helps if
1158 hook scripts need to take action based on the instance's properties
1159 (no longer need to query back into ganeti)
1160 - instance failovers when the instance is stopped do not check for free
1161 RAM, so that failing over a stopped instance is possible in low memory
1163 - rapi uses queries for tags instead of jobs (for less job traffic), and
1164 for cluster tags it won't talk to masterd at all but read them from
1166 - a couple of error handling fixes in RAPI
1167 - drbd handling: improved the error handling of inconsistent disks after
1168 resync to reduce the frequency of "there are some degraded disks for
1169 this instance" messages
1170 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1171 error handling path called a wrong function name)
1177 *(Released Wed, 27 May 2009)*
1179 - no changes from rc5
1182 Version 2.0 release candidate 5
1183 -------------------------------

1188 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1189 - some small improvements to RAPI and IAllocator
1190 - make watcher automatically start the master daemon if down
1193 Version 2.0 release candidate 4
1194 -------------------------------
1196 *(Released Mon, 27 Apr 2009)*
1198 - change the OS list to not require locks; this helps with big clusters
1199 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1200 volume group is broken
1201 - ``gnt-instance info``, without any arguments, doesn't run for all
1202 instances anymore; either pass ``--all`` or pass the desired
1203 instances; this helps against mistakes on big clusters where listing
1204 the information for all instances takes a long time
1205 - miscellaneous doc and man pages fixes
1208 Version 2.0 release candidate 3
1209 -------------------------------
1211 *(Released Wed, 8 Apr 2009)*
1213 - Change the internal locking model of some ``gnt-node`` commands, in
1214 order to reduce contention (and blocking of master daemon) when
1215 batching many creation/reinstall jobs
1216 - Fixes to Xen soft reboot
1217 - No longer build documentation at build time, instead distribute it in
1218 the archive, in order to reduce the need for the whole docbook/rst
1222 Version 2.0 release candidate 2
1223 -------------------------------
1225 *(Released Fri, 27 Mar 2009)*
1227 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1228 - Fix watcher startup sequence, improves the behaviour of busy clusters
1229 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1230 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1231 bind address and other places
1232 - Some documentation fixes and updates
1235 Version 2.0 release candidate 1
1236 -------------------------------
1238 *(Released Mon, 2 Mar 2009)*
1240 - More documentation updates, now all docs should be more-or-less
1242 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1244 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1246 - Fix an issue related to $libdir/run/ganeti and cluster creation
1252 *(Released Thu, 19 Feb 2009)*
1254 - Xen PVM and KVM have switched the default value for the instance root
1255 disk to the first partition on the first drive, instead of the whole
1256 drive; this means that the OS installation scripts must be changed
1258 - Man pages have been updated
1259 - RAPI has been switched by default to HTTPS, and the exported functions
1260 should all work correctly
1261 - RAPI v1 has been removed
1262 - Many improvements to the KVM hypervisor
1263 - Block device errors are now better reported
1264 - Many other bugfixes and small improvements
1270 *(Released Mon, 26 Jan 2009)*
1272 - Version 2 is a general rewrite of the code and therefore the
1273 differences are too many to list, see the design document for 2.0 in
1274 the ``doc/`` subdirectory for more details
1275 - In this beta version there is not yet a migration path from 1.2 (there
1276 will be one in the final 2.0 release)
1277 - A few significant changes are:
1279 - all commands are executed by a daemon (``ganeti-masterd``) and the
1280 various ``gnt-*`` commands are just front-ends to it
1281 - all the commands are entered into, and executed from a job queue,
1282 see the ``gnt-job(8)`` manpage
1283 - the RAPI daemon supports read-write operations, secured by basic
1284 HTTP authentication on top of HTTPS
1285 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1286 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1287 to migrate to DRBD 8 first while still running Ganeti 1.2)
1288 - DRBD devices are using statically allocated minor numbers, which
1289 will be assigned to existing instances during the migration process
1290 - there is support for both Xen PVM and Xen HVM instances running on
1292 - KVM virtualization is supported too
1293 - file-based storage has been implemented, which means that it is
1294 possible to run the cluster without LVM and DRBD storage, for
1295 example using a shared filesystem exported from shared storage (and
1296 still have live migration)
1302 *(Released Tue, 13 Jan 2009)*
1304 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1305 - Reuse the old instance mac address by default on instance import, if
1306 the instance name is the same.
1307 - Handle situations in which the node info rpc returns incomplete
1309 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1310 - Improved version of batcher:
1312 - state file support
1313 - instance mac address support
1314 - support for HVM clusters/instances
1316 - Add an option to show the number of cpu sockets and nodes in
1318 - Support OSes that handle more than one version of the OS api (but do
1319 not change the current API in any other way)
1320 - Fix ``gnt-node migrate``
1321 - ``gnt-debug`` man page
1322 - Fixes various more typos and small issues
1323 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1329 *(Released Wed, 24 Sep 2008)*
1331 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1332 type of disk exported to fully virtualized instances.
1333 - provide access to the serial console of HVM instances
1334 - instance auto_balance flag, set by default. If turned off it will
1335 avoid warnings on cluster verify if there is not enough memory to fail
1336 over an instance. in the future it will prevent automatically failing
1337 it over when we will support that.
1338 - batcher tool for instance creation, see ``tools/README.batcher``
1339 - ``gnt-instance reinstall --select-os`` to interactively select a new
1340 operating system when reinstalling an instance.
1341 - when changing the memory amount on instance modify a check has been
1342 added that the instance will be able to start. also warnings are
1343 emitted if the instance will not be able to fail over, if auto_balance
1345 - documentation fixes
1346 - sync fields between ``gnt-instance list/modify/add/import``
1347 - fix a race condition in drbd when the sync speed was set after giving
1348 the device a remote peer.
1354 *(Released Tue, 22 Jul 2008)*
1356 - note: the allowed size and number of tags per object were reduced
1357 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1358 - fixed twisted 8.x compatibility
1359 - fixed ``gnt-instance replace-disks`` with iallocator
1360 - add TCP keepalives on twisted connections to detect restarted nodes
1361 - disk increase support, see ``gnt-instance grow-disk``
1362 - implement bulk node/instance query for RAPI
1363 - add tags in node/instance listing (optional)
1364 - experimental migration (and live migration) support, read the man page
1365 for ``gnt-instance migrate``
1366 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1367 has some small improvements in handling its state file
1373 *(Released Fri, 13 Jun 2008)*
1375 - Experimental readonly, REST-based remote API implementation;
1376 automatically started on master node, TCP port 5080, if enabled by
1377 ``--enable-rapi`` parameter to configure script.
1378 - Instance allocator support. Add and import instance accept a
1379 ``--iallocator`` parameter, and call that instance allocator to decide
1380 which node to use for the instance. The iallocator document describes
1381 what's expected from an allocator script.
1382 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1383 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1384 node is lost there is still enough memory to fail over the instances
1386 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1387 ``gnt-cluster verify``, to check for site-specific compliance. All the
1388 hooks will run, and their output, if any, will be displayed. Any
1389 failing hook will make the verification return an error value.
1390 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1391 primary and secondary interfaces
1392 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1393 that is still declared as part of the cluster and has failed.
1394 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1395 specifying output fields, that just adds the chosen fields to the
1397 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1398 export from the filesystem.
1399 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1400 have been added. Using them you can enable/disable acpi and pae
1401 support, and specify a path for a cd image to be exported to the
1402 instance. These parameters as the name suggest only work on HVM
1404 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1405 PAE support will be set to the previously hardcoded values, but the
1406 (previously hardcoded) path to the CDROM ISO image will be unset and
1407 if required, needs to be set manually with ``gnt-instance modify``
1409 - The address to which an instance's VNC console is bound is now
1410 selectable per-instance, rather than being cluster wide. Of course
1411 this only applies to instances controlled via VNC, so currently just
1412 applies to HVM clusters.
1418 *(Released Mon, 18 Feb 2008)*
1420 - more tweaks to the disk activation code (especially helpful for DRBD)
1421 - change the default ``gnt-instance list`` output format, now there is
1422 one combined status field (see the manpage for the exact values this
1424 - some more fixes for the mac export to hooks change
1425 - make Ganeti not break with DRBD 8.2.x (which changed the version
1426 format in ``/proc/drbd``) (issue 24)
1427 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1428 template, allowing migration from DRBD0.7+MD to DRBD8
1434 *(Released Wed, 30 Jan 2008)*
1436 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1438 - add command aliases infrastructure and a few aliases
1439 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1440 man pages and the ``--help`` option of ``gnt-node
1441 list``/``gnt-instance list``
1442 - fix ``gnt-backup list`` with down nodes (issue 21)
1443 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1444 - fix the dist archive and add a check for including svn/git files in
1446 - some developer-related changes: improve the burnin and the QA suite,
1447 add an upload script for testing during development
1453 *(Released Wed, 16 Jan 2008)*
1455 - experimental HVM support, read the install document, section
1456 "Initializing the cluster"
1457 - allow for the PVM hypervisor per-instance kernel and initrd paths
1458 - add a new command ``gnt-cluster verify-disks`` which uses a new
1459 algorithm to improve the reconnection of the DRBD pairs if the device
1460 on the secondary node has gone away
1461 - make logical volume code auto-activate LVs at disk activation time
1462 - slightly improve the speed of activating disks
1463 - allow specification of the MAC address at instance creation time, and
1464 changing it later via ``gnt-instance modify``
1465 - fix handling of external commands that generate lots of output on
1467 - update documentation with regard to minimum version of DRBD8 supported
1473 *(Released Tue, 4 Dec 2007)*
1475 - Log the ``xm create`` output to the node daemon log on failure (to
1476 help diagnosing the error)
1477 - In debug mode, log all external commands output if failed to the logs
1478 - Change parsing of lvm commands to ignore stderr
1484 *(Released Wed, 28 Nov 2007)*
1486 - Another round of updates to the DRBD 8 code to deal with more failures
1487 in the replace secondary node operation
1488 - Some more logging of failures in disk operations (lvm, drbd)
1489 - A few documentation updates
1496 *(Released Tue, 13 Nov 2007)*
1498 - Change configuration file format from Python's Pickle to JSON.
1499 Upgrading is possible using the cfgupgrade utility.
1500 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1501 faster replace disks and is more stable (DRBD 8 has many improvements
1502 compared to DRBD 0.7)
1503 - Added command line tags support (see man pages for ``gnt-instance``,
1504 ``gnt-node``, ``gnt-cluster``)
1505 - Added instance rename support
1506 - Added multi-instance startup/shutdown
1507 - Added cluster rename support
1508 - Added ``gnt-node evacuate`` to simplify some node operations
1509 - Added instance reboot operation that can speedup reboot as compared to
1511 - Soften the requirement that hostnames are in FQDN format
1512 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1514 - Removed dependency on debian's patched fping that uses the
1515 non-standard ``-S`` option
1516 - Now the OS definitions are searched for in multiple, configurable
1517 paths (easier for distros to package)
1518 - Some changes to the hooks infrastructure (especially the new
1519 post-configuration update hook)
1520 - Other small bugfixes
