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.
19 - Pyparsing 1.4.6 or above is required, see :doc:`installation
20 documentation <install>`
26 *(Released Wed, 09 Mar 2011)*
28 Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
29 the RAPI users file if run twice (even with ``-dry-run``).
31 The release fixes that bug (nothing else changed).
37 *(Released Mon, 07 Mar 2011)*
39 Final 2.4.0 release. Just a few small fixes:
41 - Fixed RAPI node evacuate
42 - Fixed the kvm-ifup script
43 - Fixed internal error handling for special job cases
44 - Updated man page to specify the escaping feature for options
50 *(Released Mon, 28 Feb 2011)*
52 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
53 that this feature wiped the disks of the wrong instance, leading to loss
58 - Fixed title of query field containing instance name
59 - Expanded the glossary in the documentation
60 - Fixed one unittest (internal issue)
66 *(Released Mon, 21 Feb 2011)*
68 A number of bug fixes plus just a couple functionality changes.
70 On the user-visible side, the ``gnt-* list`` command output has changed
71 with respect to "special" field states. The current rc1 style of display
72 can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
73 the default output mode special fields states are displayed as follows:
75 - Offline resource: ``*``
76 - Unavailable/not applicable: ``-``
77 - Data missing (RPC failure): ``?``
78 - Unknown field: ``??``
80 Another user-visible change is the addition of ``--force-join`` to
85 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
86 - Fixed regression in RAPI/instance reinstall where all parameters were
87 required (instead of optional)
88 - Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
89 - Fixed iallocator usage (offline nodes were not considered offline)
90 - Fixed ``gnt-node list`` with respect to non-vm_capable nodes
91 - Fixed hypervisor and OS parameter validation with respect to
93 - Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
95 - Fixed ``tools/listrunner`` with respect to agent-based usage
101 *(Released Fri, 4 Feb 2011)*
103 Many changes and fixes since the beta1 release. While there were some
104 internal changes, the code has been mostly stabilised for the RC
107 Note: the dumb allocator was removed in this release, as it was not kept
108 up-to-date with the IAllocator protocol changes. It is recommended to
109 use the ``hail`` command from the ganeti-htools package.
111 Note: the 2.4 and up versions of Ganeti are not compatible with the
112 0.2.x branch of ganeti-htools. You need to upgrade to
113 ganeti-htools-0.3.0 (or later).
115 Regressions fixed from 2.3
116 ~~~~~~~~~~~~~~~~~~~~~~~~~~
118 - Fixed the ``gnt-cluster verify-disks`` command

121 - Fixed disk adoption breakage
122 - Fixed wrong headers in instance listing for field aliases
127 - Fixed corner case in KVM handling of NICs
128 - Fixed many cases of wrong handling of non-vm_capable nodes
129 - Fixed a bug where a missing instance symlink was not possible to

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

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

205 - ``gnt-instance list-fields``
207 - Updated documentation and man pages
212 - Moved ``rapi_users`` file into separate directory, now named
213 ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
215 - Added new tool for running commands on many machines,
216 ``tools/ganeti-listrunner``
217 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also

221 - Added support for non-partitioned md disks in ``lvmstrap``
222 - Added script to gracefully power off KVM instances
223 - Split ``utils`` module into smaller parts
224 - Changed query operations to return more detailed information, e.g.
225 whether an information is unavailable due to an offline node. To use
226 this new functionality, the LUXI call ``Query`` must be used. Field
227 information is now stored by the master daemon and can be retrieved
228 using ``QueryFields``. Instances, nodes and groups can also be queried
229 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
230 exposed via RAPI). The following commands make use of this
231 infrastructure change:
234 - ``gnt-group list-fields``
236 - ``gnt-node list-fields``
237 - ``gnt-instance list``
238 - ``gnt-instance list-fields``
239 - ``gnt-debug locks``

324 - Simplify and extend the environment variables for instance OS scripts
325 - Added new node flags, ``master_capable`` and ``vm_capable``
326 - Added optional instance disk wiping prior during allocation. This is a
327 cluster-wide option and can be set/modified using
328 ``gnt-cluster {init,modify} --prealloc-wipe-disks``.
329 - Added IPv6 support, see :doc:`design document <design-2.3>` and
331 - Added a new watcher option (``--ignore-pause``)
332 - Added option to ignore offline node on instance start/stop
333 (``--ignore-offline``)
334 - Allow overriding OS parameters with ``gnt-instance reinstall``
335 - Added ability to change node's secondary IP address using ``gnt-node

376 - Disable SSL session ID cache in RPC client
382 *(Released Thu, 14 Oct 2010)*
384 - Fix interaction between Curl/GnuTLS and the Python's HTTP server
385 (thanks Apollon Oikonomopoulos!), finally allowing the use of Curl
387 - Fix problems with interaction between Curl and Python's HTTP server,

448 - Mark opcodes following failed one as failed, too
449 - Job field ``lock_status`` was removed due to difficulties making it
450 work with the changed job queue in Ganeti 2.2; a better way to monitor
451 locks is expected for a later 2.2.x release
452 - Fixed dry-run behaviour with many commands
453 - Support ``ssh-agent`` again when adding nodes
454 - Many additional bugfixes
460 *(Released Fri, 30 Jul 2010)*
462 Important change: the internal RPC mechanism between Ganeti nodes has
463 changed from using a home-grown http library (based on the Python base
464 libraries) to use the PycURL library. This requires that PycURL is
465 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
466 against GnuTLS by default. cURL's support for GnuTLS had known issues
467 before cURL 7.21.0 and we recommend using the latest cURL release or
468 linking against OpenSSL. Most other distributions already link PycURL
469 and cURL against OpenSSL. The command::
471 python -c 'import pycurl; print pycurl.version'
473 can be used to determine the libraries PycURL and cURL are linked
476 Other significant changes:
478 - Rewrote much of the internals of the job queue, in order to achieve
479 better parallelism; this decouples job query operations from the job
480 processing, and it should allow much nicer behaviour of the master
481 daemon under load, and it also has uncovered some long-standing bugs
482 related to the job serialisation (now fixed)
483 - Added a default iallocator setting to the cluster parameters,
484 eliminating the need to always pass nodes or an iallocator for
485 operations that require selection of new node(s)
486 - Added experimental support for the LXC virtualization method
487 - Added support for OS parameters, which allows the installation of
488 instances to pass parameter to OS scripts in order to customise the
490 - Added a hypervisor parameter controlling the migration type (live or
491 non-live), since hypervisors have various levels of reliability; this
492 has renamed the 'live' parameter to 'mode'
493 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
494 logical volumes, meaning that cluster verify will ignore them and not
495 flag their presence as errors
496 - The watcher will now reset the error count for failed instances after
497 8 hours, thus allowing self-healing if the problem that caused the
498 instances to be down/fail to start has cleared in the meantime
499 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
500 check for, and warn, if the drbd module parameter ``usermode_helper``
501 is not consistent with the cluster-wide setting; this is needed to
502 make diagnose easier of failed drbd creations
503 - Started adding base IPv6 support, but this is not yet
504 enabled/available for use
505 - Rename operations (cluster, instance) will now return the new name,
506 which is especially useful if a short name was passed in
507 - Added support for instance migration in RAPI
508 - Added a tool to pre-configure nodes for the SSH setup, before joining
509 them to the cluster; this will allow in the future a simplified model
510 for node joining (but not yet fully enabled in 2.2); this needs the
511 paramiko python library
512 - Fixed handling of name-resolving errors
513 - Fixed consistency of job results on the error path
514 - Fixed master-failover race condition when executed multiple times in
516 - Fixed many bugs related to the job queue (mostly introduced during the
517 2.2 development cycle, so not all are impacting 2.1)
518 - Fixed instance migration with missing disk symlinks
519 - Fixed handling of unknown jobs in ``gnt-job archive``
520 - And many other small fixes/improvements
524 - Enhanced both the unittest and the QA coverage
525 - Switched the opcode validation to a generic model, and extended the
526 validation to all opcode parameters
527 - Changed more parts of the code that write shell scripts to use the
529 - Switched the master daemon to use the asyncore library for the Luxi
536 *(Released Thu, 17 Jun 2010)*
538 - Added tool (``move-instance``) and infrastructure to move instances
539 between separate clusters (see :doc:`separate documentation
540 <move-instance>` and :doc:`design document <design-2.2>`)
541 - Added per-request RPC timeout
542 - RAPI now requires a Content-Type header for requests with a body (e.g.
543 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
544 :rfc:`2616` (HTTP/1.1), section 7.2.1)
545 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
547 - Implemented initial support for running Ganeti daemons as separate
548 users, see configure-time flags ``--with-user-prefix`` and
549 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
551 - Instances can be removed after export (``gnt-backup export
553 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
554 key (instead of 1024 bit)
555 - Added new cluster configuration file for cluster domain secret
556 - Import/export now use SSL instead of SSH
557 - Added support for showing estimated time when exporting an instance,
558 see the ``ganeti-os-interface(7)`` manpage and look for
565 *(Released Tue, 16 Nov 2010)*
567 Some more bugfixes. Unless critical bugs occur, this will be the last
570 - Fix case of MAC special-values
571 - Fix mac checker regex
572 - backend: Fix typo causing "out of range" error
573 - Add missing --units in gnt-instance list man page
579 *(Released Tue, 24 Aug 2010)*
582 - Don't ignore secondary node silently on non-mirrored disk templates
584 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
585 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
586 - Properly document the usb_mouse parameter
587 - Fix path in ganeti-rapi(8) (issue 116)
588 - Adjust error message when the ganeti user's .ssh directory is
590 - Add same-node-check when changing the disk template to drbd
596 *(Released Fri, 16 Jul 2010)*
599 - Add an option to only select some reboot types during qa/burnin.
600 (on some hypervisors consequent reboots are not supported)
601 - Fix infrequent race condition in master failover. Sometimes the old
602 master ip address would be still detected as up for a short time
603 after it was removed, causing failover to fail.
604 - Decrease mlockall warnings when the ctypes module is missing. On
605 Python 2.4 we support running even if no ctypes module is installed,
606 but we were too verbose about this issue.
607 - Fix building on old distributions, on which man doesn't have a
609 - Fix RAPI not to ignore the MAC address on instance creation
610 - Implement the old instance creation format in the RAPI client.
616 *(Released Thu, 01 Jul 2010)*
618 A small bugfix release:
619 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
620 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
621 a non-existing option
622 - Fix instance create: the --force-variant option was ignored
623 - Improve pylint 0.21 compatibility and warnings with Python 2.6
624 - Fix modify node storage with non-FQDN arguments
625 - Fix RAPI client to authenticate under Python 2.6 when used
626 for more than 5 requests needing authentication
627 - Fix gnt-instance modify -t (storage) giving a wrong error message
628 when converting a non-shutdown drbd instance to plain
634 *(Released Fri, 18 Jun 2010)*
636 A small bugfix release:
638 - Fix live migration of KVM instances started with older Ganeti
639 versions which had fewer hypervisor parameters
640 - Fix gnt-instance grow-disk on down instances
641 - Fix an error-reporting bug during instance migration
642 - Better checking of the ``--net`` and ``--disk`` values, to avoid
643 silently ignoring broken ones
644 - Fix an RPC error reporting bug affecting, for example, RAPI client
646 - Fix bug triggered by different API version os-es on different nodes
647 - Fix a bug in instance startup with custom hvparams: OS level
648 parameters would fail to be applied.
649 - Fix the RAPI client under Python 2.6 (but more work is needed to
650 make it work completely well with OpenSSL)
651 - Fix handling of errors when resolving names from DNS
657 *(Released Thu, 3 Jun 2010)*
659 A medium sized development cycle. Some new features, and some
660 fixes/small improvements/cleanups.
665 The node deamon now tries to mlock itself into memory, unless the
666 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
667 its logs, and falls back to console logging. This allows emergency
668 features such as ``gnt-node powercycle`` to work even in the event of a
669 broken node disk (tested offlining the disk hosting the node's
670 filesystem and dropping its memory caches; don't try this at home)
672 KVM: add vhost-net acceleration support. It can be tested with a new
673 enough version of the kernel and of qemu-kvm.
675 KVM: Add instance chrooting feature. If you use privilege dropping for
676 your VMs you can also now force them to chroot to an empty directory,
677 before starting the emulated guest.
679 KVM: Add maximum migration bandwith and maximum downtime tweaking
680 support (requires a new-enough version of qemu-kvm).
682 Cluster verify will now warn if the master node doesn't have the master
685 Add a new (incompatible) instance creation request format to RAPI which
686 supports all parameters (previously only a subset was supported, and it
687 wasn't possible to extend the old format to accomodate all the new
688 features. The old format is still supported, and a client can check for
689 this feature, before using it, by checking for its presence in the
690 ``features`` RAPI resource.
692 Now with ancient latin support. Try it passing the ``--roman`` option to
693 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
694 (requires the python-roman module to be installed, in order to work).
699 As usual many internal code refactorings, documentation updates, and
702 - Lots of improvements and cleanups to the experimental Remote API
703 (RAPI) client library.
704 - A new unit test suite for the core daemon libraries.
705 - A fix to creating missing directories makes sure the umask is not
706 applied anymore. This enforces the same directory permissions
708 - Better handling terminating daemons with ctrl+c (used when running
709 them in debugging mode).
710 - Fix a race condition in live migrating a KVM instance, when stat()
711 on the old proc status file returned EINVAL, which is an unexpected
713 - Fixed manpage checking with newer man and utf-8 charachters. But now
714 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
720 *(Released Fri, 7 May 2010)*
722 Fix a bug which prevented untagged KVM instances from starting.
728 *(Released Fri, 7 May 2010)*
730 Another release with a long development cycle, during which many
731 different features were added.
736 The KVM hypervisor now can run the individual instances as non-root, to
737 reduce the impact of a VM being hijacked due to bugs in the
738 hypervisor. It is possible to run all instances as a single (non-root)
739 user, to manually specify a user for each instance, or to dynamically
740 allocate a user out of a cluster-wide pool to each instance, with the
741 guarantee that no two instances will run under the same user ID on any
744 An experimental RAPI client library, that can be used standalone
745 (without the other Ganeti libraries), is provided in the source tree as
746 ``lib/rapi/client.py``. Note this client might change its interface in
747 the future, as we iterate on its capabilities.
749 A new command, ``gnt-cluster renew-crypto`` has been added to easily
750 replace the cluster's certificates and crypto keys. This might help in
751 case they have been compromised, or have simply expired.
753 A new disk option for instance creation has been added that allows one
754 to "adopt" currently existing logical volumes, with data
755 preservation. This should allow easier migration to Ganeti from
756 unmanaged (or managed via other software) instances.
758 Another disk improvement is the possibility to convert between redundant
759 (DRBD) and plain (LVM) disk configuration for an instance. This should
760 allow better scalability (starting with one node and growing the
761 cluster, or shrinking a two-node cluster to one node).
763 A new feature that could help with automated node failovers has been
764 implemented: if a node sees itself as offline (by querying the master
765 candidates), it will try to shutdown (hard) all instances and any active
766 DRBD devices. This reduces the risk of duplicate instances if an
767 external script automatically failovers the instances on such nodes. To
768 enable this, the cluster parameter ``maintain_node_health`` should be
769 enabled; in the future this option (per the name) will enable other
770 automatic maintenance features.
772 Instance export/import now will reuse the original instance
773 specifications for all parameters; that means exporting an instance,
774 deleting it and the importing it back should give an almost identical
775 instance. Note that the default import behaviour has changed from
776 before, where it created only one NIC; now it recreates the original
779 Cluster verify has added a few new checks: SSL certificates validity,
780 /etc/hosts consistency across the cluster, etc.
785 As usual, many internal changes were done, documentation fixes,
788 - Fixed cluster initialization with disabled cluster storage (regression
790 - File-based storage supports growing the disks
791 - Fixed behaviour of node role changes
792 - Fixed cluster verify for some corner cases, plus a general rewrite of
793 cluster verify to allow future extension with more checks
794 - Fixed log spamming by watcher and node daemon (regression introduced
796 - Fixed possible validation issues when changing the list of enabled
798 - Fixed cleanup of /etc/hosts during node removal
799 - Fixed RAPI response for invalid methods
800 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
801 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
802 from ide disks, etc.)
803 - Allow OS changes without re-installation (to record a changed OS
804 outside of Ganeti, or to allow OS renames)
805 - Allow instance creation without OS installation (useful for example if
806 the OS will be installed manually, or restored from a backup not in
808 - Implemented option to make cluster ``copyfile`` use the replication
810 - Added list of enabled hypervisors to ssconf (possibly useful for
812 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
814 - A partial form of node re-IP is possible via node readd, which now
815 allows changed node primary IP
816 - Command line utilities now show an informational message if the job is
818 - The logs of the master daemon now show the PID/UID/GID of the
825 *(Released Fri, 12 Mar 2010)*
827 During the 2.1.0 long release candidate cycle, a lot of improvements and
828 changes have accumulated with were released later as 2.1.1.
833 The node evacuate command (``gnt-node evacuate``) was significantly
834 rewritten, and as such the IAllocator protocol was changed - a new
835 request type has been added. This unfortunate change during a stable
836 series is designed to improve performance of node evacuations; on
837 clusters with more than about five nodes and which are well-balanced,
838 evacuation should proceed in parallel for all instances of the node
839 being evacuated. As such, any existing IAllocator scripts need to be
840 updated, otherwise the above command will fail due to the unknown
841 request. The provided "dumb" allocator has not been updated; but the
842 ganeti-htools package supports the new protocol since version 0.2.4.
844 Another important change is increased validation of node and instance
845 names. This might create problems in special cases, if invalid host
846 names are being used.
848 Also, a new layer of hypervisor parameters has been added, that sits at
849 OS level between the cluster defaults and the instance ones. This allows
850 customisation of virtualization parameters depending on the installed
851 OS. For example instances with OS 'X' may have a different KVM kernel
852 (or any other parameter) than the cluster defaults. This is intended to
853 help managing a multiple OSes on the same cluster, without manual
854 modification of each instance's parameters.
856 A tool for merging clusters, ``cluster-merge``, has been added in the
862 - Improved the int/float conversions that should make the code more
863 robust in face of errors from the node daemons
864 - Fixed the remove node code in case of internal configuration errors
865 - Fixed the node daemon behaviour in face of inconsistent queue
866 directory (e.g. read-only file-system where we can't open the files
868 - Fixed the behaviour of gnt-node modify for master candidate demotion;
869 now it either aborts cleanly or, if given the new "auto_promote"
870 parameter, will automatically promote other nodes as needed
871 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
872 completely prevent Ganeti from working
873 - Fixed bug for instance export when not all disks were successfully
875 - Fixed behaviour of node add when the new node is slow in starting up
877 - Fixed handling of signals in the LUXI client, which should improve
878 behaviour of command-line scripts
879 - Added checks for invalid node/instance names in the configuration (now
880 flagged during cluster verify)
881 - Fixed watcher behaviour for disk activation errors
882 - Fixed two potentially endless loops in http library, which led to the
883 RAPI daemon hanging and consuming 100% CPU in some cases
884 - Fixed bug in RAPI daemon related to hashed passwords
885 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
887 - Enhanced compatibility with non-Debian OSes, but not using absolute
888 path in some commands and allowing customisation of the ssh
889 configuration directory
890 - Fixed possible future issue with new Python versions by abiding to the
891 proper use of ``__slots__`` attribute on classes
892 - Added checks that should prevent directory traversal attacks
893 - Many documentation fixes based on feedback from users
898 - Added an "early_release" more for instance replace disks and node
899 evacuate, where we release locks earlier and thus allow higher
900 parallelism within the cluster
901 - Added watcher hooks, intended to allow the watcher to restart other
902 daemons (e.g. from the ganeti-nbma project), but they can be used of
903 course for any other purpose
904 - Added a compile-time disable for DRBD barriers, to increase
905 performance if the administrator trusts the power supply or the
906 storage system to not lose writes
907 - Added the option of using syslog for logging instead of, or in
908 addition to, Ganeti's own log files
909 - Removed boot restriction for paravirtual NICs for KVM, recent versions
910 can indeed boot from a paravirtual NIC
911 - Added a generic debug level for many operations; while this is not
912 used widely yet, it allows one to pass the debug value all the way to
914 - Enhanced the hooks environment for instance moves (failovers,
915 migrations) where the primary/secondary nodes changed during the
916 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
917 - Enhanced data validations for many user-supplied values; one important
918 item is the restrictions imposed on instance and node names, which
919 might reject some (invalid) host names
920 - Add a configure-time option to disable file-based storage, if it's not
921 needed; this allows greater security separation between the master
922 node and the other nodes from the point of view of the inter-node RPC
924 - Added user notification in interactive tools if job is waiting in the
925 job queue or trying to acquire locks
926 - Added log messages when a job is waiting for locks
927 - Added filtering by node tags in instance operations which admit
928 multiple instances (start, stop, reboot, reinstall)
929 - Added a new tool for cluster mergers, ``cluster-merge``
930 - Parameters from command line which are of the form ``a=b,c=d`` can now
931 use backslash escapes to pass in values which contain commas,
932 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
934 - For KVM, the instance name is the first parameter passed to KVM, so
935 that it's more visible in the process list
941 *(Released Tue, 2 Mar 2010)*
943 Ganeti 2.1 brings many improvements with it. Major changes:
945 - Added infrastructure to ease automated disk repairs
946 - Added new daemon to export configuration data in a cheaper way than
948 - Instance NICs can now be routed instead of being associated with a
950 - Improved job locking logic to reduce impact of jobs acquiring multiple
951 locks waiting for other long-running jobs
953 In-depth implementation details can be found in the Ganeti 2.1 design
959 - Added chroot hypervisor
960 - Added more options to xen-hvm hypervisor (``kernel_path`` and
962 - Added more options to xen-pvm hypervisor (``use_bootloader``,
963 ``bootloader_path`` and ``bootloader_args``)
964 - Added the ``use_localtime`` option for the xen-hvm and kvm
965 hypervisors, and the default value for this has changed to false (in
966 2.0 xen-hvm always enabled it)
967 - Added luxi call to submit multiple jobs in one go
968 - Added cluster initialization option to not modify ``/etc/hosts``
970 - Added network interface parameters
971 - Added dry run mode to some LUs
972 - Added RAPI resources:
974 - ``/2/instances/[instance_name]/info``

980 - ``/2/nodes/[node_name]/storage/modify``
981 - ``/2/nodes/[node_name]/storage/repair``
983 - Added OpCodes to evacuate or migrate all instances on a node
984 - Added new command to list storage elements on nodes (``gnt-node
985 list-storage``) and modify them (``gnt-node modify-storage``)
986 - Added new ssconf files with master candidate IP address
987 (``ssconf_master_candidates_ips``), node primary IP address
988 (``ssconf_node_primary_ips``) and node secondary IP address
989 (``ssconf_node_secondary_ips``)
990 - Added ``ganeti-confd`` and a client library to query the Ganeti
991 configuration via UDP
992 - Added ability to run hooks after cluster initialization and before
994 - Added automatic mode for disk replace (``gnt-instance replace-disks

1004 - Added parseable error codes to cluster verification (``gnt-cluster
1005 verify --error-codes``) and made output less verbose (use
1006 ``--verbose`` to restore previous behaviour)
1007 - Added UUIDs to the main config entities (cluster, nodes, instances)
1008 - Added support for OS variants
1009 - Added support for hashed passwords in the Ganeti remote API users file
1011 - Added option to specify maximum timeout on instance shutdown
1012 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
1013 - Added new helper script to start and stop Ganeti daemons
1014 (``daemon-util``), with the intent to reduce the work necessary to
1015 adjust Ganeti for non-Debian distributions and to start/stop daemons
1017 - Added more unittests
1018 - Fixed critical bug in ganeti-masterd startup
1019 - Removed the configure-time ``kvm-migration-port`` parameter, this is
1020 now customisable at the cluster level for both the KVM and Xen
1021 hypervisors using the new ``migration_port`` parameter
1022 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
1023 reinstalling an instance
1024 - Allowed ``@`` in tag names

1046 - Improve safety of the code in some error paths
1047 - Improve data validation in the master of values returned from nodes
1053 *(Released Thu, 17 Dec 2009)*
1055 - Fix security issue due to missing validation of iallocator names; this
1056 allows local and remote execution of arbitrary executables
1057 - Fix failure of gnt-node list during instance removal
1058 - Ship the RAPI documentation in the archive
1064 *(Released Wed, 30 Sep 2009)*
1066 - Fixed many wrong messages
1067 - Fixed a few bugs related to the locking library
1068 - Fixed MAC checking at instance creation time
1069 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1070 - Fixed a few issues related to signal handling in both daemons and
1072 - Fixed the example startup script provided
1073 - Fixed insserv dependencies in the example startup script (patch from
1075 - Fixed handling of drained nodes in the iallocator framework
1076 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1078 - Fixed error related to invalid job IDs in job polling
1079 - Fixed job/opcode persistence on unclean master shutdown
1080 - Fixed handling of partial job processing after unclean master
1082 - Fixed error reporting from LUs, previously all errors were converted
1083 into execution errors
1084 - Fixed error reporting from burnin
1085 - Decreased significantly the memory usage of the job queue
1086 - Optimised slightly multi-job submission
1087 - Optimised slightly opcode loading
1088 - Backported the multi-job submit framework from the development
1089 branch; multi-instance start and stop should be faster
1090 - Added script to clean archived jobs after 21 days; this will reduce
1091 the size of the queue directory
1092 - Added some extra checks in disk size tracking
1093 - Added an example ethers hook script
1094 - Added a cluster parameter that prevents Ganeti from modifying of
1096 - Added more node information to RAPI responses
1097 - Added a ``gnt-job watch`` command that allows following the ouput of a
1099 - Added a bind-address option to ganeti-rapi
1100 - Added more checks to the configuration verify
1101 - Enhanced the burnin script such that some operations can be retried
1103 - Converted instance reinstall to multi-instance model
1109 *(Released Fri, 7 Aug 2009)*
1111 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1112 to allow using the pre-2.0.2 behaviour in activation, if any existing
1113 instances have mismatched disk sizes in the configuration
1114 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1115 any configuration mismatches for disk sizes
1116 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1117 failover to work on two-node clusters
1118 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1120 - Fixed detection of OS script errors in ``gnt-backup export``
1121 - Fixed exit code of ``gnt-backup export``
1127 *(Released Fri, 17 Jul 2009)*
1129 - Added experimental support for stripped logical volumes; this should
1130 enhance performance but comes with a higher complexity in the block
1131 device handling; stripping is only enabled when passing
1132 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1133 affected even in the non-stripped mode
1134 - Improved resiliency against transient failures at the end of DRBD
1135 resyncs, and in general of DRBD resync checks
1136 - Fixed a couple of issues with exports and snapshot errors
1137 - Fixed a couple of issues in instance listing
1138 - Added display of the disk size in ``gnt-instance info``
1139 - Fixed checking for valid OSes in instance creation
1140 - Fixed handling of the "vcpus" parameter in instance listing and in
1141 general of invalid parameters
1142 - Fixed http server library, and thus RAPI, to handle invalid
1143 username/password combinations correctly; this means that now they
1144 report unauthorized for queries too, not only for modifications,
1145 allowing earlier detect of configuration problems
1146 - Added a new "role" node list field, equivalent to the master/master
1147 candidate/drained/offline flags combinations
1148 - Fixed cluster modify and changes of candidate pool size
1149 - Fixed cluster verify error messages for wrong files on regular nodes
1150 - Fixed a couple of issues with node demotion from master candidate role
1151 - Fixed node readd issues
1152 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1153 - Added a new ``--no-voting`` option for masterfailover to fix failover
1154 on two-nodes clusters when the former master node is unreachable
1155 - Added instance reinstall over RAPI
1161 *(Released Tue, 16 Jun 2009)*
1163 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1164 allow re-adding the start in single-user option (regression from 1.2)
1165 - the watcher writes the instance status to a file, to allow monitoring
1166 to report the instance status (from the master) based on cached
1167 results of the watcher's queries; while this can get stale if the
1168 watcher is being locked due to other work on the cluster, this is
1169 still an improvement
1170 - the watcher now also restarts the node daemon and the rapi daemon if
1172 - fixed the watcher to handle full and drained queue cases
1173 - hooks export more instance data in the environment, which helps if
1174 hook scripts need to take action based on the instance's properties
1175 (no longer need to query back into ganeti)
1176 - instance failovers when the instance is stopped do not check for free
1177 RAM, so that failing over a stopped instance is possible in low memory
1179 - rapi uses queries for tags instead of jobs (for less job traffic), and
1180 for cluster tags it won't talk to masterd at all but read them from
1182 - a couple of error handling fixes in RAPI
1183 - drbd handling: improved the error handling of inconsistent disks after
1184 resync to reduce the frequency of "there are some degraded disks for
1185 this instance" messages
1186 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1187 error handling path called a wrong function name)
1193 *(Released Wed, 27 May 2009)*
1195 - no changes from rc5
1198 Version 2.0 release candidate 5
1199 -------------------------------
1201 *(Released Wed, 20 May 2009)*
1203 - fix a couple of bugs (validation, argument checks)
1204 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1205 - some small improvements to RAPI and IAllocator
1206 - make watcher automatically start the master daemon if down
1209 Version 2.0 release candidate 4
1210 -------------------------------
1212 *(Released Mon, 27 Apr 2009)*
1214 - change the OS list to not require locks; this helps with big clusters
1215 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1216 volume group is broken
1217 - ``gnt-instance info``, without any arguments, doesn't run for all
1218 instances anymore; either pass ``--all`` or pass the desired
1219 instances; this helps against mistakes on big clusters where listing
1220 the information for all instances takes a long time
1221 - miscellaneous doc and man pages fixes
1224 Version 2.0 release candidate 3
1225 -------------------------------
1227 *(Released Wed, 8 Apr 2009)*
1229 - Change the internal locking model of some ``gnt-node`` commands, in
1230 order to reduce contention (and blocking of master daemon) when
1231 batching many creation/reinstall jobs
1232 - Fixes to Xen soft reboot
1233 - No longer build documentation at build time, instead distribute it in
1234 the archive, in order to reduce the need for the whole docbook/rst
1238 Version 2.0 release candidate 2
1239 -------------------------------
1241 *(Released Fri, 27 Mar 2009)*
1243 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1244 - Fix watcher startup sequence, improves the behaviour of busy clusters
1245 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1246 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1247 bind address and other places
1248 - Some documentation fixes and updates
1251 Version 2.0 release candidate 1
1252 -------------------------------
1254 *(Released Mon, 2 Mar 2009)*
1256 - More documentation updates, now all docs should be more-or-less
1258 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1260 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1262 - Fix an issue related to $libdir/run/ganeti and cluster creation
1268 *(Released Thu, 19 Feb 2009)*
1270 - Xen PVM and KVM have switched the default value for the instance root
1271 disk to the first partition on the first drive, instead of the whole
1272 drive; this means that the OS installation scripts must be changed
1274 - Man pages have been updated
1275 - RAPI has been switched by default to HTTPS, and the exported functions
1276 should all work correctly
1277 - RAPI v1 has been removed
1278 - Many improvements to the KVM hypervisor
1279 - Block device errors are now better reported
1280 - Many other bugfixes and small improvements
1286 *(Released Mon, 26 Jan 2009)*
1288 - Version 2 is a general rewrite of the code and therefore the
1289 differences are too many to list, see the design document for 2.0 in
1290 the ``doc/`` subdirectory for more details
1291 - In this beta version there is not yet a migration path from 1.2 (there
1292 will be one in the final 2.0 release)
1293 - A few significant changes are:
1295 - all commands are executed by a daemon (``ganeti-masterd``) and the
1296 various ``gnt-*`` commands are just front-ends to it
1297 - all the commands are entered into, and executed from a job queue,
1298 see the ``gnt-job(8)`` manpage
1299 - the RAPI daemon supports read-write operations, secured by basic
1300 HTTP authentication on top of HTTPS
1301 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1302 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1303 to migrate to DRBD 8 first while still running Ganeti 1.2)
1304 - DRBD devices are using statically allocated minor numbers, which
1305 will be assigned to existing instances during the migration process
1306 - there is support for both Xen PVM and Xen HVM instances running on
1308 - KVM virtualization is supported too
1309 - file-based storage has been implemented, which means that it is
1310 possible to run the cluster without LVM and DRBD storage, for
1311 example using a shared filesystem exported from shared storage (and
1312 still have live migration)
1318 *(Released Tue, 13 Jan 2009)*
1320 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1321 - Reuse the old instance mac address by default on instance import, if
1322 the instance name is the same.
1323 - Handle situations in which the node info rpc returns incomplete
1325 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1326 - Improved version of batcher:
1328 - state file support
1329 - instance mac address support
1330 - support for HVM clusters/instances
1332 - Add an option to show the number of cpu sockets and nodes in
1334 - Support OSes that handle more than one version of the OS api (but do
1335 not change the current API in any other way)
1336 - Fix ``gnt-node migrate``
1337 - ``gnt-debug`` man page
1338 - Fixes various more typos and small issues
1339 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1345 *(Released Wed, 24 Sep 2008)*
1347 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1348 type of disk exported to fully virtualized instances.
1349 - provide access to the serial console of HVM instances
1350 - instance auto_balance flag, set by default. If turned off it will
1351 avoid warnings on cluster verify if there is not enough memory to fail
1352 over an instance. in the future it will prevent automatically failing
1353 it over when we will support that.
1354 - batcher tool for instance creation, see ``tools/README.batcher``
1355 - ``gnt-instance reinstall --select-os`` to interactively select a new
1356 operating system when reinstalling an instance.
1357 - when changing the memory amount on instance modify a check has been
1358 added that the instance will be able to start. also warnings are
1359 emitted if the instance will not be able to fail over, if auto_balance
1361 - documentation fixes
1362 - sync fields between ``gnt-instance list/modify/add/import``
1363 - fix a race condition in drbd when the sync speed was set after giving
1364 the device a remote peer.
1370 *(Released Tue, 22 Jul 2008)*
1372 - note: the allowed size and number of tags per object were reduced
1373 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1374 - fixed twisted 8.x compatibility
1375 - fixed ``gnt-instance replace-disks`` with iallocator
1376 - add TCP keepalives on twisted connections to detect restarted nodes
1377 - disk increase support, see ``gnt-instance grow-disk``
1378 - implement bulk node/instance query for RAPI
1379 - add tags in node/instance listing (optional)
1380 - experimental migration (and live migration) support, read the man page
1381 for ``gnt-instance migrate``
1382 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1383 has some small improvements in handling its state file
1389 *(Released Fri, 13 Jun 2008)*
1391 - Experimental readonly, REST-based remote API implementation;
1392 automatically started on master node, TCP port 5080, if enabled by
1393 ``--enable-rapi`` parameter to configure script.
1394 - Instance allocator support. Add and import instance accept a
1395 ``--iallocator`` parameter, and call that instance allocator to decide
1396 which node to use for the instance. The iallocator document describes
1397 what's expected from an allocator script.
1398 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1399 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1400 node is lost there is still enough memory to fail over the instances
1402 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1403 ``gnt-cluster verify``, to check for site-specific compliance. All the
1404 hooks will run, and their output, if any, will be displayed. Any
1405 failing hook will make the verification return an error value.
1406 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1407 primary and secondary interfaces
1408 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1409 that is still declared as part of the cluster and has failed.
1410 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1411 specifying output fields, that just adds the chosen fields to the
1413 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1414 export from the filesystem.
1415 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1416 have been added. Using them you can enable/disable acpi and pae
1417 support, and specify a path for a cd image to be exported to the
1418 instance. These parameters as the name suggest only work on HVM
1420 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1421 PAE support will be set to the previously hardcoded values, but the
1422 (previously hardcoded) path to the CDROM ISO image will be unset and
1423 if required, needs to be set manually with ``gnt-instance modify``
1425 - The address to which an instance's VNC console is bound is now
1426 selectable per-instance, rather than being cluster wide. Of course
1427 this only applies to instances controlled via VNC, so currently just
1428 applies to HVM clusters.
1434 *(Released Mon, 18 Feb 2008)*
1436 - more tweaks to the disk activation code (especially helpful for DRBD)
1437 - change the default ``gnt-instance list`` output format, now there is
1438 one combined status field (see the manpage for the exact values this
1440 - some more fixes for the mac export to hooks change
1441 - make Ganeti not break with DRBD 8.2.x (which changed the version
1442 format in ``/proc/drbd``) (issue 24)
1443 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1444 template, allowing migration from DRBD0.7+MD to DRBD8
1450 *(Released Wed, 30 Jan 2008)*
1452 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1454 - add command aliases infrastructure and a few aliases
1455 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1456 man pages and the ``--help`` option of ``gnt-node
1457 list``/``gnt-instance list``
1458 - fix ``gnt-backup list`` with down nodes (issue 21)
1459 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1460 - fix the dist archive and add a check for including svn/git files in
1462 - some developer-related changes: improve the burnin and the QA suite,
1463 add an upload script for testing during development
1469 *(Released Wed, 16 Jan 2008)*
1471 - experimental HVM support, read the install document, section
1472 "Initializing the cluster"
1473 - allow for the PVM hypervisor per-instance kernel and initrd paths
1474 - add a new command ``gnt-cluster verify-disks`` which uses a new
1475 algorithm to improve the reconnection of the DRBD pairs if the device
1476 on the secondary node has gone away
1477 - make logical volume code auto-activate LVs at disk activation time
1478 - slightly improve the speed of activating disks
1479 - allow specification of the MAC address at instance creation time, and
1480 changing it later via ``gnt-instance modify``
1481 - fix handling of external commands that generate lots of output on
1483 - update documentation with regard to minimum version of DRBD8 supported
1489 *(Released Tue, 4 Dec 2007)*
1491 - Log the ``xm create`` output to the node daemon log on failure (to
1492 help diagnosing the error)
1493 - In debug mode, log all external commands output if failed to the logs
1494 - Change parsing of lvm commands to ignore stderr
1500 *(Released Wed, 28 Nov 2007)*
1502 - Another round of updates to the DRBD 8 code to deal with more failures
1503 in the replace secondary node operation
1504 - Some more logging of failures in disk operations (lvm, drbd)
1505 - A few documentation updates
1512 *(Released Tue, 13 Nov 2007)*
1514 - Change configuration file format from Python's Pickle to JSON.
1515 Upgrading is possible using the cfgupgrade utility.
1516 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1517 faster replace disks and is more stable (DRBD 8 has many improvements
1518 compared to DRBD 0.7)
1519 - Added command line tags support (see man pages for ``gnt-instance``,
1520 ``gnt-node``, ``gnt-cluster``)
1521 - Added instance rename support
1522 - Added multi-instance startup/shutdown
1523 - Added cluster rename support
1524 - Added ``gnt-node evacuate`` to simplify some node operations
1525 - Added instance reboot operation that can speedup reboot as compared to
1527 - Soften the requirement that hostnames are in FQDN format
1528 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1530 - Removed dependency on debian's patched fping that uses the
1531 non-standard ``-S`` option
1532 - Now the OS definitions are searched for in multiple, configurable
1533 paths (easier for distros to package)
1534 - Some changes to the hooks infrastructure (especially the new
1535 post-configuration update hook)
1536 - Other small bugfixes
