7 *(Released Mon, 07 Mar 2011)*
9 Final 2.4.0 release. Just a few small fixes:
11 - Fixed RAPI node evacuate
12 - Fixed the kvm-ifup script
13 - Fixed internal error handling for special job cases
14 - Updated man page to specify the escaping feature for options
20 *(Released Mon, 28 Feb 2011)*
22 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
23 that this feature wiped the disks of the wrong instance, leading to loss
28 - Fixed title of query field containing instance name
29 - Expanded the glossary in the documentation
30 - Fixed one unittest (internal issue)
36 *(Released Mon, 21 Feb 2011)*
38 A number of bug fixes plus just a couple functionality changes.
40 On the user-visible side, the ``gnt-* list`` command output has changed
41 with respect to "special" field states. The current rc1 style of display
42 can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
43 the default output mode special fields states are displayed as follows:
45 - Offline resource: ``*``
46 - Unavailable/not applicable: ``-``
47 - Data missing (RPC failure): ``?``
48 - Unknown field: ``??``
50 Another user-visible change is the addition of ``--force-join`` to
55 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
56 - Fixed regression in RAPI/instance reinstall where all parameters were
57 required (instead of optional)
58 - Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
59 - Fixed iallocator usage (offline nodes were not considered offline)
60 - Fixed ``gnt-node list`` with respect to non-vm_capable nodes
61 - Fixed hypervisor and OS parameter validation with respect to
63 - Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
65 - Fixed ``tools/listrunner`` with respect to agent-based usage
71 *(Released Fri, 4 Feb 2011)*
73 Many changes and fixes since the beta1 release. While there were some
74 internal changes, the code has been mostly stabilised for the RC
77 Note: the dumb allocator was removed in this release, as it was not kept
78 up-to-date with the IAllocator protocol changes. It is recommended to
79 use the ``hail`` command from the ganeti-htools package.
81 Note: the 2.4 and up versions of Ganeti are not compatible with the
82 0.2.x branch of ganeti-htools. You need to upgrade to
83 ganeti-htools-0.3.0 (or later).
85 Regressions fixed from 2.3
86 ~~~~~~~~~~~~~~~~~~~~~~~~~~
88 - Fixed the ``gnt-cluster verify-disks`` command

91 - Fixed disk adoption breakage
92 - Fixed wrong headers in instance listing for field aliases
97 - Fixed corner case in KVM handling of NICs
98 - Fixed many cases of wrong handling of non-vm_capable nodes
99 - Fixed a bug where a missing instance symlink was not possible to
100 recreate with any ``gnt-*`` command (now ``gnt-instance
101 activate-disks`` does it)
102 - Fixed the volume group name as reported by ``gnt-cluster
104 - Increased timeouts for the import-export code, hopefully leading to
105 fewer aborts due network or instance timeouts
106 - Fixed bug in ``gnt-node list-storage``
107 - Fixed bug where not all daemons were started on cluster
108 initialisation, but only at the first watcher run

110 - Fixed watcher behaviour in presence of instances with offline
112 - Fixed instance list output for instances running on the wrong node
113 - a few fixes to the cluster-merge tool, but it still cannot merge
114 multi-node groups (currently it is not recommended to use this tool)
120 - Improved network configuration for the KVM hypervisor
121 - Added e1000 as a supported NIC for Xen-HVM
122 - Improved the lvmstrap tool to also be able to use partitions, as
123 opposed to full disks
124 - Improved speed of disk wiping (the cluster parameter
125 ``prealloc_wipe_disks``, so that it has a low impact on the total time
126 of instance creations
127 - Added documentation for the OS parameters
128 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
129 hypervisor is not responding
130 - Added display of blacklisted and hidden OS information in
132 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
133 NIC and node parameters, which might create problems with currently
134 invalid (but undetected) configuration files, but prevents validation
135 failures when unrelated parameters are modified
136 - Changed cluster initialisation to wait for the master daemon to become
138 - Expanded the RAPI interface:
140 - Added config redistribution resource
141 - Added activation/deactivation of instance disks
142 - Added export of console information
144 - Implemented log file reopening on SIGHUP, which allows using
145 logrotate(8) for the Ganeti log files
146 - Added a basic OOB helper script as an example
152 *(Released Fri, 14 Jan 2011)*
157 - Fixed timezone issues when formatting timestamps

166 - Accept offline secondaries while shutting down instance disks
167 - Added ``blockdev_prefix`` parameter to Xen PVM and HVM hypervisors
168 - Added support for multiple LVM volume groups
169 - Avoid sorting nodes for ``gnt-node list`` if specific nodes are
171 - Added commands to list available fields:
173 - ``gnt-node list-fields``
174 - ``gnt-group list-fields``
175 - ``gnt-instance list-fields``
177 - Updated documentation and man pages
182 - Moved ``rapi_users`` file into separate directory, now named
183 ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
185 - Added new tool for running commands on many machines,
186 ``tools/ganeti-listrunner``
187 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also
188 improving the ``gnt-instance console`` output

191 - Added support for non-partitioned md disks in ``lvmstrap``
192 - Added script to gracefully power off KVM instances
193 - Split ``utils`` module into smaller parts
194 - Changed query operations to return more detailed information, e.g.
195 whether an information is unavailable due to an offline node. To use
196 this new functionality, the LUXI call ``Query`` must be used. Field
197 information is now stored by the master daemon and can be retrieved
198 using ``QueryFields``. Instances, nodes and groups can also be queried
199 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
200 exposed via RAPI). The following commands make use of this
201 infrastructure change:
204 - ``gnt-group list-fields``
206 - ``gnt-node list-fields``
207 - ``gnt-instance list``
208 - ``gnt-instance list-fields``
209 - ``gnt-debug locks``

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

421 locks is expected for a later 2.2.x release
422 - Fixed dry-run behaviour with many commands
423 - Support ``ssh-agent`` again when adding nodes
424 - Many additional bugfixes
430 *(Released Fri, 30 Jul 2010)*
432 Important change: the internal RPC mechanism between Ganeti nodes has
433 changed from using a home-grown http library (based on the Python base
434 libraries) to use the PycURL library. This requires that PycURL is
435 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
436 against GnuTLS by default. cURL's support for GnuTLS had known issues
437 before cURL 7.21.0 and we recommend using the latest cURL release or
438 linking against OpenSSL. Most other distributions already link PycURL
439 and cURL against OpenSSL. The command::
441 python -c 'import pycurl; print pycurl.version'
443 can be used to determine the libraries PycURL and cURL are linked
446 Other significant changes:
448 - Rewrote much of the internals of the job queue, in order to achieve
449 better parallelism; this decouples job query operations from the job
450 processing, and it should allow much nicer behaviour of the master
451 daemon under load, and it also has uncovered some long-standing bugs
452 related to the job serialisation (now fixed)
453 - Added a default iallocator setting to the cluster parameters,
454 eliminating the need to always pass nodes or an iallocator for
455 operations that require selection of new node(s)
456 - Added experimental support for the LXC virtualization method
457 - Added support for OS parameters, which allows the installation of
458 instances to pass parameter to OS scripts in order to customise the
460 - Added a hypervisor parameter controlling the migration type (live or
461 non-live), since hypervisors have various levels of reliability; this
462 has renamed the 'live' parameter to 'mode'
463 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
464 logical volumes, meaning that cluster verify will ignore them and not
465 flag their presence as errors
466 - The watcher will now reset the error count for failed instances after
467 8 hours, thus allowing self-healing if the problem that caused the
468 instances to be down/fail to start has cleared in the meantime
469 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
470 check for, and warn, if the drbd module parameter ``usermode_helper``
471 is not consistent with the cluster-wide setting; this is needed to
472 make diagnose easier of failed drbd creations
473 - Started adding base IPv6 support, but this is not yet
474 enabled/available for use
475 - Rename operations (cluster, instance) will now return the new name,
476 which is especially useful if a short name was passed in
477 - Added support for instance migration in RAPI
478 - Added a tool to pre-configure nodes for the SSH setup, before joining
479 them to the cluster; this will allow in the future a simplified model
480 for node joining (but not yet fully enabled in 2.2); this needs the
481 paramiko python library
482 - Fixed handling of name-resolving errors
483 - Fixed consistency of job results on the error path
484 - Fixed master-failover race condition when executed multiple times in
486 - Fixed many bugs related to the job queue (mostly introduced during the
487 2.2 development cycle, so not all are impacting 2.1)
488 - Fixed instance migration with missing disk symlinks
489 - Fixed handling of unknown jobs in ``gnt-job archive``
490 - And many other small fixes/improvements
494 - Enhanced both the unittest and the QA coverage
495 - Switched the opcode validation to a generic model, and extended the
496 validation to all opcode parameters
497 - Changed more parts of the code that write shell scripts to use the
499 - Switched the master daemon to use the asyncore library for the Luxi
506 *(Released Thu, 17 Jun 2010)*
508 - Added tool (``move-instance``) and infrastructure to move instances
509 between separate clusters (see :doc:`separate documentation
510 <move-instance>` and :doc:`design document <design-2.2>`)
511 - Added per-request RPC timeout
512 - RAPI now requires a Content-Type header for requests with a body (e.g.
513 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
514 :rfc:`2616` (HTTP/1.1), section 7.2.1)
515 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
517 - Implemented initial support for running Ganeti daemons as separate
518 users, see configure-time flags ``--with-user-prefix`` and
519 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
521 - Instances can be removed after export (``gnt-backup export
523 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
524 key (instead of 1024 bit)
525 - Added new cluster configuration file for cluster domain secret
526 - Import/export now use SSL instead of SSH
527 - Added support for showing estimated time when exporting an instance,
528 see the ``ganeti-os-interface(7)`` manpage and look for
535 *(Released Tue, 16 Nov 2010)*
537 Some more bugfixes. Unless critical bugs occur, this will be the last
540 - Fix case of MAC special-values
541 - Fix mac checker regex
542 - backend: Fix typo causing "out of range" error
543 - Add missing --units in gnt-instance list man page
549 *(Released Tue, 24 Aug 2010)*
552 - Don't ignore secondary node silently on non-mirrored disk templates
554 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
555 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
556 - Properly document the usb_mouse parameter
557 - Fix path in ganeti-rapi(8) (issue 116)
558 - Adjust error message when the ganeti user's .ssh directory is
560 - Add same-node-check when changing the disk template to drbd
566 *(Released Fri, 16 Jul 2010)*
569 - Add an option to only select some reboot types during qa/burnin.
570 (on some hypervisors consequent reboots are not supported)
571 - Fix infrequent race condition in master failover. Sometimes the old
572 master ip address would be still detected as up for a short time
573 after it was removed, causing failover to fail.
574 - Decrease mlockall warnings when the ctypes module is missing. On
575 Python 2.4 we support running even if no ctypes module is installed,
576 but we were too verbose about this issue.
577 - Fix building on old distributions, on which man doesn't have a
579 - Fix RAPI not to ignore the MAC address on instance creation
580 - Implement the old instance creation format in the RAPI client.
586 *(Released Thu, 01 Jul 2010)*
588 A small bugfix release:
589 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
590 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
591 a non-existing option
592 - Fix instance create: the --force-variant option was ignored
593 - Improve pylint 0.21 compatibility and warnings with Python 2.6
594 - Fix modify node storage with non-FQDN arguments
595 - Fix RAPI client to authenticate under Python 2.6 when used
596 for more than 5 requests needing authentication
597 - Fix gnt-instance modify -t (storage) giving a wrong error message
598 when converting a non-shutdown drbd instance to plain
604 *(Released Fri, 18 Jun 2010)*
606 A small bugfix release:
608 - Fix live migration of KVM instances started with older Ganeti
609 versions which had fewer hypervisor parameters
610 - Fix gnt-instance grow-disk on down instances
611 - Fix an error-reporting bug during instance migration
612 - Better checking of the ``--net`` and ``--disk`` values, to avoid
613 silently ignoring broken ones
614 - Fix an RPC error reporting bug affecting, for example, RAPI client
616 - Fix bug triggered by different API version os-es on different nodes
617 - Fix a bug in instance startup with custom hvparams: OS level
618 parameters would fail to be applied.
619 - Fix the RAPI client under Python 2.6 (but more work is needed to
620 make it work completely well with OpenSSL)
621 - Fix handling of errors when resolving names from DNS
627 *(Released Thu, 3 Jun 2010)*
629 A medium sized development cycle. Some new features, and some
630 fixes/small improvements/cleanups.
635 The node deamon now tries to mlock itself into memory, unless the
636 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
637 its logs, and falls back to console logging. This allows emergency
638 features such as ``gnt-node powercycle`` to work even in the event of a
639 broken node disk (tested offlining the disk hosting the node's
640 filesystem and dropping its memory caches; don't try this at home)
642 KVM: add vhost-net acceleration support. It can be tested with a new
643 enough version of the kernel and of qemu-kvm.
645 KVM: Add instance chrooting feature. If you use privilege dropping for
646 your VMs you can also now force them to chroot to an empty directory,
647 before starting the emulated guest.
649 KVM: Add maximum migration bandwith and maximum downtime tweaking
650 support (requires a new-enough version of qemu-kvm).
652 Cluster verify will now warn if the master node doesn't have the master
655 Add a new (incompatible) instance creation request format to RAPI which
656 supports all parameters (previously only a subset was supported, and it
657 wasn't possible to extend the old format to accomodate all the new
658 features. The old format is still supported, and a client can check for
659 this feature, before using it, by checking for its presence in the
660 ``features`` RAPI resource.
662 Now with ancient latin support. Try it passing the ``--roman`` option to
663 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
664 (requires the python-roman module to be installed, in order to work).
669 As usual many internal code refactorings, documentation updates, and
672 - Lots of improvements and cleanups to the experimental Remote API
673 (RAPI) client library.
674 - A new unit test suite for the core daemon libraries.
675 - A fix to creating missing directories makes sure the umask is not
676 applied anymore. This enforces the same directory permissions
678 - Better handling terminating daemons with ctrl+c (used when running
679 them in debugging mode).
680 - Fix a race condition in live migrating a KVM instance, when stat()
681 on the old proc status file returned EINVAL, which is an unexpected
683 - Fixed manpage checking with newer man and utf-8 charachters. But now
684 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
690 *(Released Fri, 7 May 2010)*
692 Fix a bug which prevented untagged KVM instances from starting.
698 *(Released Fri, 7 May 2010)*
700 Another release with a long development cycle, during which many
701 different features were added.
706 The KVM hypervisor now can run the individual instances as non-root, to
707 reduce the impact of a VM being hijacked due to bugs in the
708 hypervisor. It is possible to run all instances as a single (non-root)
709 user, to manually specify a user for each instance, or to dynamically
710 allocate a user out of a cluster-wide pool to each instance, with the
711 guarantee that no two instances will run under the same user ID on any
714 An experimental RAPI client library, that can be used standalone
715 (without the other Ganeti libraries), is provided in the source tree as
716 ``lib/rapi/client.py``. Note this client might change its interface in
717 the future, as we iterate on its capabilities.
719 A new command, ``gnt-cluster renew-crypto`` has been added to easily
720 replace the cluster's certificates and crypto keys. This might help in
721 case they have been compromised, or have simply expired.
723 A new disk option for instance creation has been added that allows one
724 to "adopt" currently existing logical volumes, with data
725 preservation. This should allow easier migration to Ganeti from
726 unmanaged (or managed via other software) instances.
728 Another disk improvement is the possibility to convert between redundant
729 (DRBD) and plain (LVM) disk configuration for an instance. This should
730 allow better scalability (starting with one node and growing the
731 cluster, or shrinking a two-node cluster to one node).
733 A new feature that could help with automated node failovers has been
734 implemented: if a node sees itself as offline (by querying the master
735 candidates), it will try to shutdown (hard) all instances and any active
736 DRBD devices. This reduces the risk of duplicate instances if an
737 external script automatically failovers the instances on such nodes. To
738 enable this, the cluster parameter ``maintain_node_health`` should be
739 enabled; in the future this option (per the name) will enable other
740 automatic maintenance features.
742 Instance export/import now will reuse the original instance
743 specifications for all parameters; that means exporting an instance,
744 deleting it and the importing it back should give an almost identical
745 instance. Note that the default import behaviour has changed from
746 before, where it created only one NIC; now it recreates the original
749 Cluster verify has added a few new checks: SSL certificates validity,
750 /etc/hosts consistency across the cluster, etc.
755 As usual, many internal changes were done, documentation fixes,
758 - Fixed cluster initialization with disabled cluster storage (regression
760 - File-based storage supports growing the disks
761 - Fixed behaviour of node role changes
762 - Fixed cluster verify for some corner cases, plus a general rewrite of
763 cluster verify to allow future extension with more checks
764 - Fixed log spamming by watcher and node daemon (regression introduced
766 - Fixed possible validation issues when changing the list of enabled
768 - Fixed cleanup of /etc/hosts during node removal
769 - Fixed RAPI response for invalid methods
770 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
771 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
772 from ide disks, etc.)
773 - Allow OS changes without re-installation (to record a changed OS
774 outside of Ganeti, or to allow OS renames)
775 - Allow instance creation without OS installation (useful for example if
776 the OS will be installed manually, or restored from a backup not in
778 - Implemented option to make cluster ``copyfile`` use the replication
780 - Added list of enabled hypervisors to ssconf (possibly useful for
782 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
784 - A partial form of node re-IP is possible via node readd, which now
785 allows changed node primary IP
786 - Command line utilities now show an informational message if the job is
788 - The logs of the master daemon now show the PID/UID/GID of the
795 *(Released Fri, 12 Mar 2010)*
797 During the 2.1.0 long release candidate cycle, a lot of improvements and
798 changes have accumulated with were released later as 2.1.1.
803 The node evacuate command (``gnt-node evacuate``) was significantly
804 rewritten, and as such the IAllocator protocol was changed - a new
805 request type has been added. This unfortunate change during a stable
806 series is designed to improve performance of node evacuations; on
807 clusters with more than about five nodes and which are well-balanced,
808 evacuation should proceed in parallel for all instances of the node
809 being evacuated. As such, any existing IAllocator scripts need to be
810 updated, otherwise the above command will fail due to the unknown
811 request. The provided "dumb" allocator has not been updated; but the
812 ganeti-htools package supports the new protocol since version 0.2.4.
814 Another important change is increased validation of node and instance
815 names. This might create problems in special cases, if invalid host
816 names are being used.
818 Also, a new layer of hypervisor parameters has been added, that sits at
819 OS level between the cluster defaults and the instance ones. This allows
820 customisation of virtualization parameters depending on the installed
821 OS. For example instances with OS 'X' may have a different KVM kernel
822 (or any other parameter) than the cluster defaults. This is intended to
823 help managing a multiple OSes on the same cluster, without manual
824 modification of each instance's parameters.
826 A tool for merging clusters, ``cluster-merge``, has been added in the
832 - Improved the int/float conversions that should make the code more
833 robust in face of errors from the node daemons
834 - Fixed the remove node code in case of internal configuration errors
835 - Fixed the node daemon behaviour in face of inconsistent queue
836 directory (e.g. read-only file-system where we can't open the files
838 - Fixed the behaviour of gnt-node modify for master candidate demotion;
839 now it either aborts cleanly or, if given the new "auto_promote"
840 parameter, will automatically promote other nodes as needed
841 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
842 completely prevent Ganeti from working
843 - Fixed bug for instance export when not all disks were successfully
845 - Fixed behaviour of node add when the new node is slow in starting up
847 - Fixed handling of signals in the LUXI client, which should improve
848 behaviour of command-line scripts
849 - Added checks for invalid node/instance names in the configuration (now
850 flagged during cluster verify)
851 - Fixed watcher behaviour for disk activation errors
852 - Fixed two potentially endless loops in http library, which led to the
853 RAPI daemon hanging and consuming 100% CPU in some cases
854 - Fixed bug in RAPI daemon related to hashed passwords
855 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
857 - Enhanced compatibility with non-Debian OSes, but not using absolute
858 path in some commands and allowing customisation of the ssh
859 configuration directory
860 - Fixed possible future issue with new Python versions by abiding to the
861 proper use of ``__slots__`` attribute on classes
862 - Added checks that should prevent directory traversal attacks
863 - Many documentation fixes based on feedback from users
868 - Added an "early_release" more for instance replace disks and node
869 evacuate, where we release locks earlier and thus allow higher
870 parallelism within the cluster
871 - Added watcher hooks, intended to allow the watcher to restart other
872 daemons (e.g. from the ganeti-nbma project), but they can be used of
873 course for any other purpose
874 - Added a compile-time disable for DRBD barriers, to increase
875 performance if the administrator trusts the power supply or the
876 storage system to not lose writes
877 - Added the option of using syslog for logging instead of, or in
878 addition to, Ganeti's own log files
879 - Removed boot restriction for paravirtual NICs for KVM, recent versions
880 can indeed boot from a paravirtual NIC
881 - Added a generic debug level for many operations; while this is not
882 used widely yet, it allows one to pass the debug value all the way to
884 - Enhanced the hooks environment for instance moves (failovers,
885 migrations) where the primary/secondary nodes changed during the
886 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
887 - Enhanced data validations for many user-supplied values; one important
888 item is the restrictions imposed on instance and node names, which
889 might reject some (invalid) host names
890 - Add a configure-time option to disable file-based storage, if it's not
891 needed; this allows greater security separation between the master
892 node and the other nodes from the point of view of the inter-node RPC
894 - Added user notification in interactive tools if job is waiting in the
895 job queue or trying to acquire locks
896 - Added log messages when a job is waiting for locks
897 - Added filtering by node tags in instance operations which admit
898 multiple instances (start, stop, reboot, reinstall)
899 - Added a new tool for cluster mergers, ``cluster-merge``
900 - Parameters from command line which are of the form ``a=b,c=d`` can now
901 use backslash escapes to pass in values which contain commas,
902 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
904 - For KVM, the instance name is the first parameter passed to KVM, so
905 that it's more visible in the process list
911 *(Released Tue, 2 Mar 2010)*
913 Ganeti 2.1 brings many improvements with it. Major changes:
915 - Added infrastructure to ease automated disk repairs
916 - Added new daemon to export configuration data in a cheaper way than
918 - Instance NICs can now be routed instead of being associated with a
920 - Improved job locking logic to reduce impact of jobs acquiring multiple
921 locks waiting for other long-running jobs
923 In-depth implementation details can be found in the Ganeti 2.1 design
929 - Added chroot hypervisor
930 - Added more options to xen-hvm hypervisor (``kernel_path`` and
932 - Added more options to xen-pvm hypervisor (``use_bootloader``,
933 ``bootloader_path`` and ``bootloader_args``)
934 - Added the ``use_localtime`` option for the xen-hvm and kvm
935 hypervisors, and the default value for this has changed to false (in
936 2.0 xen-hvm always enabled it)
937 - Added luxi call to submit multiple jobs in one go
938 - Added cluster initialization option to not modify ``/etc/hosts``
940 - Added network interface parameters
941 - Added dry run mode to some LUs

950 - ``/2/nodes/[node_name]/storage/modify``
951 - ``/2/nodes/[node_name]/storage/repair``
953 - Added OpCodes to evacuate or migrate all instances on a node
954 - Added new command to list storage elements on nodes (``gnt-node
955 list-storage``) and modify them (``gnt-node modify-storage``)
956 - Added new ssconf files with master candidate IP address
957 (``ssconf_master_candidates_ips``), node primary IP address
958 (``ssconf_node_primary_ips``) and node secondary IP address
959 (``ssconf_node_secondary_ips``)
960 - Added ``ganeti-confd`` and a client library to query the Ganeti
961 configuration via UDP
962 - Added ability to run hooks after cluster initialization and before
964 - Added automatic mode for disk replace (``gnt-instance replace-disks
966 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks

973 - Added new job status field ``lock_status``
974 - Added parseable error codes to cluster verification (``gnt-cluster
975 verify --error-codes``) and made output less verbose (use
976 ``--verbose`` to restore previous behaviour)
977 - Added UUIDs to the main config entities (cluster, nodes, instances)
978 - Added support for OS variants
979 - Added support for hashed passwords in the Ganeti remote API users file
981 - Added option to specify maximum timeout on instance shutdown
982 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
983 - Added new helper script to start and stop Ganeti daemons
984 (``daemon-util``), with the intent to reduce the work necessary to
985 adjust Ganeti for non-Debian distributions and to start/stop daemons
987 - Added more unittests
988 - Fixed critical bug in ganeti-masterd startup
989 - Removed the configure-time ``kvm-migration-port`` parameter, this is
990 now customisable at the cluster level for both the KVM and Xen
991 hypervisors using the new ``migration_port`` parameter
992 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
993 reinstalling an instance
994 - Allowed ``@`` in tag names

1026 allows local and remote execution of arbitrary executables
1027 - Fix failure of gnt-node list during instance removal
1028 - Ship the RAPI documentation in the archive
1034 *(Released Wed, 30 Sep 2009)*
1036 - Fixed many wrong messages
1037 - Fixed a few bugs related to the locking library
1038 - Fixed MAC checking at instance creation time
1039 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1040 - Fixed a few issues related to signal handling in both daemons and
1042 - Fixed the example startup script provided
1043 - Fixed insserv dependencies in the example startup script (patch from
1045 - Fixed handling of drained nodes in the iallocator framework
1046 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1048 - Fixed error related to invalid job IDs in job polling
1049 - Fixed job/opcode persistence on unclean master shutdown
1050 - Fixed handling of partial job processing after unclean master
1052 - Fixed error reporting from LUs, previously all errors were converted
1053 into execution errors
1054 - Fixed error reporting from burnin
1055 - Decreased significantly the memory usage of the job queue
1056 - Optimised slightly multi-job submission
1057 - Optimised slightly opcode loading
1058 - Backported the multi-job submit framework from the development
1059 branch; multi-instance start and stop should be faster
1060 - Added script to clean archived jobs after 21 days; this will reduce
1061 the size of the queue directory
1062 - Added some extra checks in disk size tracking
1063 - Added an example ethers hook script
1064 - Added a cluster parameter that prevents Ganeti from modifying of
1066 - Added more node information to RAPI responses
1067 - Added a ``gnt-job watch`` command that allows following the ouput of a
1069 - Added a bind-address option to ganeti-rapi
1070 - Added more checks to the configuration verify
1071 - Enhanced the burnin script such that some operations can be retried
1073 - Converted instance reinstall to multi-instance model
1079 *(Released Fri, 7 Aug 2009)*
1081 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1082 to allow using the pre-2.0.2 behaviour in activation, if any existing
1083 instances have mismatched disk sizes in the configuration
1084 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1085 any configuration mismatches for disk sizes
1086 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1087 failover to work on two-node clusters
1088 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1090 - Fixed detection of OS script errors in ``gnt-backup export``
1091 - Fixed exit code of ``gnt-backup export``
1097 *(Released Fri, 17 Jul 2009)*
1099 - Added experimental support for stripped logical volumes; this should
1100 enhance performance but comes with a higher complexity in the block
1101 device handling; stripping is only enabled when passing
1102 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1103 affected even in the non-stripped mode
1104 - Improved resiliency against transient failures at the end of DRBD
1105 resyncs, and in general of DRBD resync checks
1106 - Fixed a couple of issues with exports and snapshot errors
1107 - Fixed a couple of issues in instance listing
1108 - Added display of the disk size in ``gnt-instance info``
1109 - Fixed checking for valid OSes in instance creation
1110 - Fixed handling of the "vcpus" parameter in instance listing and in
1111 general of invalid parameters
1112 - Fixed http server library, and thus RAPI, to handle invalid
1113 username/password combinations correctly; this means that now they
1114 report unauthorized for queries too, not only for modifications,
1115 allowing earlier detect of configuration problems
1116 - Added a new "role" node list field, equivalent to the master/master
1117 candidate/drained/offline flags combinations
1118 - Fixed cluster modify and changes of candidate pool size
1119 - Fixed cluster verify error messages for wrong files on regular nodes
1120 - Fixed a couple of issues with node demotion from master candidate role
1121 - Fixed node readd issues
1122 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1123 - Added a new ``--no-voting`` option for masterfailover to fix failover
1124 on two-nodes clusters when the former master node is unreachable
1125 - Added instance reinstall over RAPI
1131 *(Released Tue, 16 Jun 2009)*
1133 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1134 allow re-adding the start in single-user option (regression from 1.2)
1135 - the watcher writes the instance status to a file, to allow monitoring
1136 to report the instance status (from the master) based on cached
1137 results of the watcher's queries; while this can get stale if the
1138 watcher is being locked due to other work on the cluster, this is
1139 still an improvement
1140 - the watcher now also restarts the node daemon and the rapi daemon if
1142 - fixed the watcher to handle full and drained queue cases
1143 - hooks export more instance data in the environment, which helps if
1144 hook scripts need to take action based on the instance's properties
1145 (no longer need to query back into ganeti)
1146 - instance failovers when the instance is stopped do not check for free
1147 RAM, so that failing over a stopped instance is possible in low memory
1149 - rapi uses queries for tags instead of jobs (for less job traffic), and
1150 for cluster tags it won't talk to masterd at all but read them from
1152 - a couple of error handling fixes in RAPI
1153 - drbd handling: improved the error handling of inconsistent disks after
1154 resync to reduce the frequency of "there are some degraded disks for
1155 this instance" messages
1156 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1157 error handling path called a wrong function name)
1163 *(Released Wed, 27 May 2009)*
1165 - no changes from rc5
1168 Version 2.0 release candidate 5
1169 -------------------------------

1174 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1175 - some small improvements to RAPI and IAllocator
1176 - make watcher automatically start the master daemon if down
1179 Version 2.0 release candidate 4
1180 -------------------------------
1182 *(Released Mon, 27 Apr 2009)*
1184 - change the OS list to not require locks; this helps with big clusters
1185 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1186 volume group is broken
1187 - ``gnt-instance info``, without any arguments, doesn't run for all
1188 instances anymore; either pass ``--all`` or pass the desired
1189 instances; this helps against mistakes on big clusters where listing
1190 the information for all instances takes a long time
1191 - miscellaneous doc and man pages fixes
1194 Version 2.0 release candidate 3
1195 -------------------------------
1197 *(Released Wed, 8 Apr 2009)*
1199 - Change the internal locking model of some ``gnt-node`` commands, in
1200 order to reduce contention (and blocking of master daemon) when
1201 batching many creation/reinstall jobs
1202 - Fixes to Xen soft reboot
1203 - No longer build documentation at build time, instead distribute it in
1204 the archive, in order to reduce the need for the whole docbook/rst
1208 Version 2.0 release candidate 2
1209 -------------------------------
1211 *(Released Fri, 27 Mar 2009)*
1213 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1214 - Fix watcher startup sequence, improves the behaviour of busy clusters
1215 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1216 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1217 bind address and other places
1218 - Some documentation fixes and updates
1221 Version 2.0 release candidate 1
1222 -------------------------------
1224 *(Released Mon, 2 Mar 2009)*
1226 - More documentation updates, now all docs should be more-or-less
1228 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1230 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1232 - Fix an issue related to $libdir/run/ganeti and cluster creation
1238 *(Released Thu, 19 Feb 2009)*
1240 - Xen PVM and KVM have switched the default value for the instance root
1241 disk to the first partition on the first drive, instead of the whole
1242 drive; this means that the OS installation scripts must be changed
1244 - Man pages have been updated
1245 - RAPI has been switched by default to HTTPS, and the exported functions
1246 should all work correctly
1247 - RAPI v1 has been removed
1248 - Many improvements to the KVM hypervisor
1249 - Block device errors are now better reported
1250 - Many other bugfixes and small improvements
1256 *(Released Mon, 26 Jan 2009)*
1258 - Version 2 is a general rewrite of the code and therefore the
1259 differences are too many to list, see the design document for 2.0 in
1260 the ``doc/`` subdirectory for more details
1261 - In this beta version there is not yet a migration path from 1.2 (there
1262 will be one in the final 2.0 release)
1263 - A few significant changes are:
1265 - all commands are executed by a daemon (``ganeti-masterd``) and the
1266 various ``gnt-*`` commands are just front-ends to it
1267 - all the commands are entered into, and executed from a job queue,
1268 see the ``gnt-job(8)`` manpage
1269 - the RAPI daemon supports read-write operations, secured by basic
1270 HTTP authentication on top of HTTPS
1271 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1272 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1273 to migrate to DRBD 8 first while still running Ganeti 1.2)
1274 - DRBD devices are using statically allocated minor numbers, which
1275 will be assigned to existing instances during the migration process
1276 - there is support for both Xen PVM and Xen HVM instances running on
1278 - KVM virtualization is supported too
1279 - file-based storage has been implemented, which means that it is
1280 possible to run the cluster without LVM and DRBD storage, for
1281 example using a shared filesystem exported from shared storage (and
1282 still have live migration)
1288 *(Released Tue, 13 Jan 2009)*
1290 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1291 - Reuse the old instance mac address by default on instance import, if
1292 the instance name is the same.
1293 - Handle situations in which the node info rpc returns incomplete
1295 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1296 - Improved version of batcher:
1298 - state file support
1299 - instance mac address support
1300 - support for HVM clusters/instances
1302 - Add an option to show the number of cpu sockets and nodes in
1304 - Support OSes that handle more than one version of the OS api (but do
1305 not change the current API in any other way)
1306 - Fix ``gnt-node migrate``
1307 - ``gnt-debug`` man page
1308 - Fixes various more typos and small issues
1309 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1315 *(Released Wed, 24 Sep 2008)*
1317 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1318 type of disk exported to fully virtualized instances.
1319 - provide access to the serial console of HVM instances
1320 - instance auto_balance flag, set by default. If turned off it will
1321 avoid warnings on cluster verify if there is not enough memory to fail
1322 over an instance. in the future it will prevent automatically failing
1323 it over when we will support that.
1324 - batcher tool for instance creation, see ``tools/README.batcher``
1325 - ``gnt-instance reinstall --select-os`` to interactively select a new
1326 operating system when reinstalling an instance.
1327 - when changing the memory amount on instance modify a check has been
1328 added that the instance will be able to start. also warnings are
1329 emitted if the instance will not be able to fail over, if auto_balance
1331 - documentation fixes
1332 - sync fields between ``gnt-instance list/modify/add/import``
1333 - fix a race condition in drbd when the sync speed was set after giving
1334 the device a remote peer.
1340 *(Released Tue, 22 Jul 2008)*
1342 - note: the allowed size and number of tags per object were reduced
1343 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1344 - fixed twisted 8.x compatibility
1345 - fixed ``gnt-instance replace-disks`` with iallocator
1346 - add TCP keepalives on twisted connections to detect restarted nodes
1347 - disk increase support, see ``gnt-instance grow-disk``
1348 - implement bulk node/instance query for RAPI
1349 - add tags in node/instance listing (optional)
1350 - experimental migration (and live migration) support, read the man page
1351 for ``gnt-instance migrate``
1352 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1353 has some small improvements in handling its state file
1359 *(Released Fri, 13 Jun 2008)*
1361 - Experimental readonly, REST-based remote API implementation;
1362 automatically started on master node, TCP port 5080, if enabled by
1363 ``--enable-rapi`` parameter to configure script.
1364 - Instance allocator support. Add and import instance accept a
1365 ``--iallocator`` parameter, and call that instance allocator to decide
1366 which node to use for the instance. The iallocator document describes
1367 what's expected from an allocator script.
1368 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1369 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1370 node is lost there is still enough memory to fail over the instances
1372 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1373 ``gnt-cluster verify``, to check for site-specific compliance. All the
1374 hooks will run, and their output, if any, will be displayed. Any
1375 failing hook will make the verification return an error value.
1376 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1377 primary and secondary interfaces
1378 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1379 that is still declared as part of the cluster and has failed.
1380 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1381 specifying output fields, that just adds the chosen fields to the
1383 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1384 export from the filesystem.
1385 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1386 have been added. Using them you can enable/disable acpi and pae
1387 support, and specify a path for a cd image to be exported to the
1388 instance. These parameters as the name suggest only work on HVM
1390 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1391 PAE support will be set to the previously hardcoded values, but the
1392 (previously hardcoded) path to the CDROM ISO image will be unset and
1393 if required, needs to be set manually with ``gnt-instance modify``
1395 - The address to which an instance's VNC console is bound is now
1396 selectable per-instance, rather than being cluster wide. Of course
1397 this only applies to instances controlled via VNC, so currently just
1398 applies to HVM clusters.
1404 *(Released Mon, 18 Feb 2008)*
1406 - more tweaks to the disk activation code (especially helpful for DRBD)
1407 - change the default ``gnt-instance list`` output format, now there is
1408 one combined status field (see the manpage for the exact values this
1410 - some more fixes for the mac export to hooks change
1411 - make Ganeti not break with DRBD 8.2.x (which changed the version
1412 format in ``/proc/drbd``) (issue 24)
1413 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1414 template, allowing migration from DRBD0.7+MD to DRBD8
1420 *(Released Wed, 30 Jan 2008)*
1422 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1424 - add command aliases infrastructure and a few aliases
1425 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1426 man pages and the ``--help`` option of ``gnt-node
1427 list``/``gnt-instance list``
1428 - fix ``gnt-backup list`` with down nodes (issue 21)
1429 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1430 - fix the dist archive and add a check for including svn/git files in
1432 - some developer-related changes: improve the burnin and the QA suite,
1433 add an upload script for testing during development
1439 *(Released Wed, 16 Jan 2008)*
1441 - experimental HVM support, read the install document, section
1442 "Initializing the cluster"
1443 - allow for the PVM hypervisor per-instance kernel and initrd paths
1444 - add a new command ``gnt-cluster verify-disks`` which uses a new
1445 algorithm to improve the reconnection of the DRBD pairs if the device
1446 on the secondary node has gone away
1447 - make logical volume code auto-activate LVs at disk activation time
1448 - slightly improve the speed of activating disks
1449 - allow specification of the MAC address at instance creation time, and
1450 changing it later via ``gnt-instance modify``
1451 - fix handling of external commands that generate lots of output on
1453 - update documentation with regard to minimum version of DRBD8 supported
1459 *(Released Tue, 4 Dec 2007)*
1461 - Log the ``xm create`` output to the node daemon log on failure (to
1462 help diagnosing the error)
1463 - In debug mode, log all external commands output if failed to the logs
1464 - Change parsing of lvm commands to ignore stderr
1470 *(Released Wed, 28 Nov 2007)*
1472 - Another round of updates to the DRBD 8 code to deal with more failures
1473 in the replace secondary node operation
1474 - Some more logging of failures in disk operations (lvm, drbd)
1475 - A few documentation updates
1482 *(Released Tue, 13 Nov 2007)*
1484 - Change configuration file format from Python's Pickle to JSON.
1485 Upgrading is possible using the cfgupgrade utility.
1486 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1487 faster replace disks and is more stable (DRBD 8 has many improvements
1488 compared to DRBD 0.7)
1489 - Added command line tags support (see man pages for ``gnt-instance``,
1490 ``gnt-node``, ``gnt-cluster``)
1491 - Added instance rename support
1492 - Added multi-instance startup/shutdown
1493 - Added cluster rename support

1500 - Removed dependency on debian's patched fping that uses the
1501 non-standard ``-S`` option
1502 - Now the OS definitions are searched for in multiple, configurable
1503 paths (easier for distros to package)
1504 - Some changes to the hooks infrastructure (especially the new
1505 post-configuration update hook)
1506 - Other small bugfixes
