24 - Fixed a bug in ``ensure-dirs`` with queue/archive permissions
25 - Fixed a parsing issue with DRBD 8.3.11 in the Linux kernel
31 *(Released Fri, 5 Aug 2011)*

36 issues when you tried to add an instance with two MAC addresses in one
38 - KVM: fixed per-instance stored UID value
39 - KVM: configure bridged NICs at migration start
40 - KVM: Fix a bug where instance will not start with never KVM versions
42 - Added OS search path to ``gnt-cluster info``
43 - Fixed an issue with ``file_storage_dir`` where you were forced to
44 provide an absolute path, but the documentation states it is a
45 relative path, the documentation was right
46 - Added a new parameter to instance stop/start called ``--no-remember``
47 that will make the state change to not be remembered
48 - Implemented ``no_remember`` at RAPI level
49 - Improved the documentation
50 - Node evacuation: don't call IAllocator if node is already empty
51 - Fixed bug in DRBD8 replace disks on current nodes
52 - Fixed bug in recreate-disks for DRBD instances
53 - Moved assertion checking locks in ``gnt-instance replace-disks``
54 causing it to abort with not owning the right locks for some situation
55 - Job queue: Fixed potential race condition when cancelling queued jobs

61 - Bugfixes to non-root Ganeti configuration
67 *(Released Thu, 12 May 2011)*
69 Many bug-fixes and a few new small features:
71 - Fixed a bug related to log opening failures
72 - Fixed a bug in instance listing with orphan instances
73 - Fixed a bug which prevented resetting the cluster-level node parameter
74 ``oob_program`` to the default
75 - Many fixes related to the ``cluster-merge`` tool
76 - Fixed a race condition in the lock monitor, which caused failures
77 during (at least) creation of many instances in parallel
78 - Improved output for gnt-job info
79 - Removed the quiet flag on some ssh calls which prevented debugging
81 - Improved the N+1 failure messages in cluster verify by actually
82 showing the memory values (needed and available)
83 - Increased lock attempt timeouts so that when executing long operations
84 (e.g. DRBD replace-disks) other jobs do not enter 'blocking acquire'
85 too early and thus prevent the use of the 'fair' mechanism
86 - Changed instance query data (``gnt-instance info``) to not acquire
87 locks unless needed, thus allowing its use on locked instance if only
88 static information is asked for
89 - Improved behaviour with filesystems that do not support rename on an
91 - Fixed the behaviour of ``prealloc_wipe_disks`` cluster parameter which
92 kept locks on all nodes during the wipe, which is unneeded
93 - Fixed ``gnt-watcher`` handling of errors during hooks execution
94 - Fixed bug in ``prealloc_wipe_disks`` with small disk sizes (less than
95 10GiB) which caused the wipe to fail right at the end in some cases
96 - Fixed master IP activation when doing master failover with no-voting
97 - Fixed bug in ``gnt-node add --readd`` which allowed the re-adding of
98 the master node itself
99 - Fixed potential data-loss in under disk full conditions, where Ganeti
100 wouldn't check correctly the return code and would consider
101 partially-written files 'correct'
102 - Fixed bug related to multiple VGs and DRBD disk replacing
103 - Added new disk parameter ``metavg`` that allows placement of the meta
104 device for DRBD in a different volume group
105 - Fixed error handling in the node daemon when the system libc doesn't
106 have major number 6 (i.e. if ``libc.so.6`` is not the actual libc)
107 - Fixed lock release during replace-disks, which kept cluster-wide locks
108 when doing disk replaces with an iallocator script
109 - Added check for missing bridges in cluster verify
110 - Handle EPIPE errors while writing to the terminal better, so that
111 piping the output to e.g. ``less`` doesn't cause a backtrace
112 - Fixed rare case where a ^C during Luxi calls could have been
113 interpreted as server errors, instead of simply terminating
114 - Fixed a race condition in LUGroupAssignNodes (``gnt-group
116 - Added a few more parameters to the KVM hypervisor, allowing a second
117 CDROM, custom disk type for CDROMs and a floppy image
118 - Removed redundant message in instance rename when the name is given
120 - Added option to ``gnt-instance recreate-disks`` to allow creating the
121 disks on new nodes, allowing recreation when the original instance
122 nodes are completely gone
123 - Added option when converting disk templates to DRBD to skip waiting
124 for the resync, in order to make the instance available sooner
125 - Added two new variables to the OS scripts environment (containing the
127 - Made the root_path and optional parameter for the xen-pvm hypervisor,
128 to allow use of ``pvgrub`` as bootloader
129 - Changed the instance memory modifications to only check out-of-memory
130 conditions on memory increases, and turned the secondary node warnings
131 into errors (they can still be overridden via ``--force``)
132 - Fixed the handling of a corner case when the Python installation gets
133 corrupted (e.g. a bad disk) while ganeti-noded is running and we try
134 to execute a command that doesn't exist
135 - Fixed a bug in ``gnt-instance move`` (LUInstanceMove) when the primary
136 node of the instance returned failures during instance shutdown; this
137 adds the option ``--ignore-consistency`` to gnt-instance move
139 And as usual, various improvements to the error messages, documentation
145 *(Released Wed, 09 Mar 2011)*
147 Emergency bug-fix release. ``tools/cfgupgrade`` was broken and overwrote
148 the RAPI users file if run twice (even with ``--dry-run``).
150 The release fixes that bug (nothing else changed).
156 *(Released Mon, 07 Mar 2011)*
158 Final 2.4.0 release. Just a few small fixes:
160 - Fixed RAPI node evacuate
161 - Fixed the kvm-ifup script
162 - Fixed internal error handling for special job cases
163 - Updated man page to specify the escaping feature for options
169 *(Released Mon, 28 Feb 2011)*
171 A critical fix for the ``prealloc_wipe_disks`` feature: it is possible
172 that this feature wiped the disks of the wrong instance, leading to loss
177 - Fixed title of query field containing instance name
178 - Expanded the glossary in the documentation
179 - Fixed one unittest (internal issue)
185 *(Released Mon, 21 Feb 2011)*
187 A number of bug fixes plus just a couple functionality changes.
189 On the user-visible side, the ``gnt-* list`` command output has changed
190 with respect to "special" field states. The current rc1 style of display
191 can be re-enabled by passing a new ``--verbose`` (``-v``) flag, but in
192 the default output mode special fields states are displayed as follows:
194 - Offline resource: ``*``
195 - Unavailable/not applicable: ``-``
196 - Data missing (RPC failure): ``?``
197 - Unknown field: ``??``
199 Another user-visible change is the addition of ``--force-join`` to
204 - ``tools/cluster-merge`` has seen many fixes and is now enabled again
205 - Fixed regression in RAPI/instance reinstall where all parameters were
206 required (instead of optional)
207 - Fixed ``gnt-cluster repair-disk-sizes``, was broken since Ganeti 2.2
208 - Fixed iallocator usage (offline nodes were not considered offline)
209 - Fixed ``gnt-node list`` with respect to non-vm_capable nodes
210 - Fixed hypervisor and OS parameter validation with respect to
212 - Fixed ``gnt-cluster verify`` with respect to offline nodes (mostly
214 - Fixed ``tools/listrunner`` with respect to agent-based usage
220 *(Released Fri, 4 Feb 2011)*
222 Many changes and fixes since the beta1 release. While there were some
223 internal changes, the code has been mostly stabilised for the RC
226 Note: the dumb allocator was removed in this release, as it was not kept
227 up-to-date with the IAllocator protocol changes. It is recommended to
228 use the ``hail`` command from the ganeti-htools package.
230 Note: the 2.4 and up versions of Ganeti are not compatible with the
231 0.2.x branch of ganeti-htools. You need to upgrade to
232 ganeti-htools-0.3.0 (or later).
234 Regressions fixed from 2.3

263 multi-node groups (currently it is not recommended to use this tool)
269 - Improved network configuration for the KVM hypervisor
270 - Added e1000 as a supported NIC for Xen-HVM
271 - Improved the lvmstrap tool to also be able to use partitions, as
272 opposed to full disks
273 - Improved speed of disk wiping (the cluster parameter
274 ``prealloc_wipe_disks``, so that it has a low impact on the total time
275 of instance creations
276 - Added documentation for the OS parameters
277 - Changed ``gnt-instance deactivate-disks`` so that it can work if the
278 hypervisor is not responding
279 - Added display of blacklisted and hidden OS information in
281 - Extended ``gnt-cluster verify`` to also validate hypervisor, backend,
282 NIC and node parameters, which might create problems with currently
283 invalid (but undetected) configuration files, but prevents validation
284 failures when unrelated parameters are modified
285 - Changed cluster initialisation to wait for the master daemon to become
287 - Expanded the RAPI interface:
289 - Added config redistribution resource
290 - Added activation/deactivation of instance disks
291 - Added export of console information
293 - Implemented log file reopening on SIGHUP, which allows using
294 logrotate(8) for the Ganeti log files
295 - Added a basic OOB helper script as an example
301 *(Released Fri, 14 Jan 2011)*
306 - Fixed timezone issues when formatting timestamps

324 - ``gnt-instance list-fields``
326 - Updated documentation and man pages
331 - Moved ``rapi_users`` file into separate directory, now named
332 ``.../ganeti/rapi/users``, ``cfgupgrade`` moves the file and creates a
334 - Added new tool for running commands on many machines,
335 ``tools/ganeti-listrunner``
336 - Implemented more verbose result in ``OpInstanceConsole`` opcode, also

341 - Added script to gracefully power off KVM instances
342 - Split ``utils`` module into smaller parts
343 - Changed query operations to return more detailed information, e.g.
344 whether an information is unavailable due to an offline node. To use
345 this new functionality, the LUXI call ``Query`` must be used. Field
346 information is now stored by the master daemon and can be retrieved
347 using ``QueryFields``. Instances, nodes and groups can also be queried
348 using the new opcodes ``OpQuery`` and ``OpQueryFields`` (not yet
349 exposed via RAPI). The following commands make use of this
350 infrastructure change:
353 - ``gnt-group list-fields``
355 - ``gnt-node list-fields``
356 - ``gnt-instance list``
357 - ``gnt-instance list-fields``

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

571 - Fixed dry-run behaviour with many commands
572 - Support ``ssh-agent`` again when adding nodes
573 - Many additional bugfixes
579 *(Released Fri, 30 Jul 2010)*
581 Important change: the internal RPC mechanism between Ganeti nodes has
582 changed from using a home-grown http library (based on the Python base
583 libraries) to use the PycURL library. This requires that PycURL is
584 installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
585 against GnuTLS by default. cURL's support for GnuTLS had known issues
586 before cURL 7.21.0 and we recommend using the latest cURL release or
587 linking against OpenSSL. Most other distributions already link PycURL
588 and cURL against OpenSSL. The command::
590 python -c 'import pycurl; print pycurl.version'
592 can be used to determine the libraries PycURL and cURL are linked
595 Other significant changes:
597 - Rewrote much of the internals of the job queue, in order to achieve
598 better parallelism; this decouples job query operations from the job
599 processing, and it should allow much nicer behaviour of the master
600 daemon under load, and it also has uncovered some long-standing bugs
601 related to the job serialisation (now fixed)
602 - Added a default iallocator setting to the cluster parameters,
603 eliminating the need to always pass nodes or an iallocator for
604 operations that require selection of new node(s)
605 - Added experimental support for the LXC virtualization method
606 - Added support for OS parameters, which allows the installation of
607 instances to pass parameter to OS scripts in order to customise the
609 - Added a hypervisor parameter controlling the migration type (live or
610 non-live), since hypervisors have various levels of reliability; this
611 has renamed the 'live' parameter to 'mode'
612 - Added a cluster parameter ``reserved_lvs`` that denotes reserved
613 logical volumes, meaning that cluster verify will ignore them and not
614 flag their presence as errors
615 - The watcher will now reset the error count for failed instances after
616 8 hours, thus allowing self-healing if the problem that caused the
617 instances to be down/fail to start has cleared in the meantime
618 - Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
619 check for, and warn, if the drbd module parameter ``usermode_helper``
620 is not consistent with the cluster-wide setting; this is needed to
621 make diagnose easier of failed drbd creations
622 - Started adding base IPv6 support, but this is not yet
623 enabled/available for use
624 - Rename operations (cluster, instance) will now return the new name,
625 which is especially useful if a short name was passed in
626 - Added support for instance migration in RAPI
627 - Added a tool to pre-configure nodes for the SSH setup, before joining
628 them to the cluster; this will allow in the future a simplified model
629 for node joining (but not yet fully enabled in 2.2); this needs the
630 paramiko python library
631 - Fixed handling of name-resolving errors
632 - Fixed consistency of job results on the error path
633 - Fixed master-failover race condition when executed multiple times in
635 - Fixed many bugs related to the job queue (mostly introduced during the
636 2.2 development cycle, so not all are impacting 2.1)
637 - Fixed instance migration with missing disk symlinks
638 - Fixed handling of unknown jobs in ``gnt-job archive``
639 - And many other small fixes/improvements
643 - Enhanced both the unittest and the QA coverage
644 - Switched the opcode validation to a generic model, and extended the
645 validation to all opcode parameters
646 - Changed more parts of the code that write shell scripts to use the
648 - Switched the master daemon to use the asyncore library for the Luxi
655 *(Released Thu, 17 Jun 2010)*
657 - Added tool (``move-instance``) and infrastructure to move instances
658 between separate clusters (see :doc:`separate documentation
659 <move-instance>` and :doc:`design document <design-2.2>`)
660 - Added per-request RPC timeout
661 - RAPI now requires a Content-Type header for requests with a body (e.g.
662 ``PUT`` or ``POST``) which must be set to ``application/json`` (see
663 :rfc:`2616` (HTTP/1.1), section 7.2.1)
664 - ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
666 - Implemented initial support for running Ganeti daemons as separate
667 users, see configure-time flags ``--with-user-prefix`` and
668 ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
670 - Instances can be removed after export (``gnt-backup export
672 - Self-signed certificates generated by Ganeti now use a 2048 bit RSA
673 key (instead of 1024 bit)
674 - Added new cluster configuration file for cluster domain secret
675 - Import/export now use SSL instead of SSH
676 - Added support for showing estimated time when exporting an instance,
677 see the ``ganeti-os-interface(7)`` manpage and look for
684 *(Released Tue, 16 Nov 2010)*
686 Some more bugfixes. Unless critical bugs occur, this will be the last
689 - Fix case of MAC special-values
690 - Fix mac checker regex
691 - backend: Fix typo causing "out of range" error
692 - Add missing --units in gnt-instance list man page
698 *(Released Tue, 24 Aug 2010)*
701 - Don't ignore secondary node silently on non-mirrored disk templates
703 - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
704 - Fix usb_mouse parameter breaking with vnc_console (issue 109)
705 - Properly document the usb_mouse parameter
706 - Fix path in ganeti-rapi(8) (issue 116)
707 - Adjust error message when the ganeti user's .ssh directory is
709 - Add same-node-check when changing the disk template to drbd
715 *(Released Fri, 16 Jul 2010)*
718 - Add an option to only select some reboot types during qa/burnin.
719 (on some hypervisors consequent reboots are not supported)
720 - Fix infrequent race condition in master failover. Sometimes the old
721 master ip address would be still detected as up for a short time
722 after it was removed, causing failover to fail.
723 - Decrease mlockall warnings when the ctypes module is missing. On
724 Python 2.4 we support running even if no ctypes module is installed,
725 but we were too verbose about this issue.
726 - Fix building on old distributions, on which man doesn't have a
728 - Fix RAPI not to ignore the MAC address on instance creation
729 - Implement the old instance creation format in the RAPI client.
735 *(Released Thu, 01 Jul 2010)*
737 A small bugfix release:
738 - Fix disk adoption: broken by strict --disk option checking in 2.1.4
739 - Fix batch-create: broken in the whole 2.1 series due to a lookup on
740 a non-existing option
741 - Fix instance create: the --force-variant option was ignored
742 - Improve pylint 0.21 compatibility and warnings with Python 2.6
743 - Fix modify node storage with non-FQDN arguments
744 - Fix RAPI client to authenticate under Python 2.6 when used
745 for more than 5 requests needing authentication
746 - Fix gnt-instance modify -t (storage) giving a wrong error message
747 when converting a non-shutdown drbd instance to plain
753 *(Released Fri, 18 Jun 2010)*
755 A small bugfix release:
757 - Fix live migration of KVM instances started with older Ganeti
758 versions which had fewer hypervisor parameters
759 - Fix gnt-instance grow-disk on down instances
760 - Fix an error-reporting bug during instance migration
761 - Better checking of the ``--net`` and ``--disk`` values, to avoid
762 silently ignoring broken ones
763 - Fix an RPC error reporting bug affecting, for example, RAPI client
765 - Fix bug triggered by different API version os-es on different nodes
766 - Fix a bug in instance startup with custom hvparams: OS level
767 parameters would fail to be applied.
768 - Fix the RAPI client under Python 2.6 (but more work is needed to
769 make it work completely well with OpenSSL)
770 - Fix handling of errors when resolving names from DNS
776 *(Released Thu, 3 Jun 2010)*
778 A medium sized development cycle. Some new features, and some
779 fixes/small improvements/cleanups.
784 The node deamon now tries to mlock itself into memory, unless the
785 ``--no-mlock`` flag is passed. It also doesn't fail if it can't write
786 its logs, and falls back to console logging. This allows emergency
787 features such as ``gnt-node powercycle`` to work even in the event of a
788 broken node disk (tested offlining the disk hosting the node's
789 filesystem and dropping its memory caches; don't try this at home)
791 KVM: add vhost-net acceleration support. It can be tested with a new
792 enough version of the kernel and of qemu-kvm.
794 KVM: Add instance chrooting feature. If you use privilege dropping for
795 your VMs you can also now force them to chroot to an empty directory,
796 before starting the emulated guest.
798 KVM: Add maximum migration bandwith and maximum downtime tweaking
799 support (requires a new-enough version of qemu-kvm).
801 Cluster verify will now warn if the master node doesn't have the master
804 Add a new (incompatible) instance creation request format to RAPI which
805 supports all parameters (previously only a subset was supported, and it
806 wasn't possible to extend the old format to accomodate all the new
807 features. The old format is still supported, and a client can check for
808 this feature, before using it, by checking for its presence in the
809 ``features`` RAPI resource.
811 Now with ancient latin support. Try it passing the ``--roman`` option to
812 ``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
813 (requires the python-roman module to be installed, in order to work).
818 As usual many internal code refactorings, documentation updates, and
821 - Lots of improvements and cleanups to the experimental Remote API
822 (RAPI) client library.
823 - A new unit test suite for the core daemon libraries.
824 - A fix to creating missing directories makes sure the umask is not
825 applied anymore. This enforces the same directory permissions
827 - Better handling terminating daemons with ctrl+c (used when running
828 them in debugging mode).
829 - Fix a race condition in live migrating a KVM instance, when stat()
830 on the old proc status file returned EINVAL, which is an unexpected
832 - Fixed manpage checking with newer man and utf-8 charachters. But now
833 you need the en_US.UTF-8 locale enabled to build Ganeti from git.
839 *(Released Fri, 7 May 2010)*
841 Fix a bug which prevented untagged KVM instances from starting.
847 *(Released Fri, 7 May 2010)*
849 Another release with a long development cycle, during which many
850 different features were added.
855 The KVM hypervisor now can run the individual instances as non-root, to
856 reduce the impact of a VM being hijacked due to bugs in the
857 hypervisor. It is possible to run all instances as a single (non-root)
858 user, to manually specify a user for each instance, or to dynamically
859 allocate a user out of a cluster-wide pool to each instance, with the
860 guarantee that no two instances will run under the same user ID on any
863 An experimental RAPI client library, that can be used standalone
864 (without the other Ganeti libraries), is provided in the source tree as
865 ``lib/rapi/client.py``. Note this client might change its interface in
866 the future, as we iterate on its capabilities.
868 A new command, ``gnt-cluster renew-crypto`` has been added to easily
869 replace the cluster's certificates and crypto keys. This might help in
870 case they have been compromised, or have simply expired.
872 A new disk option for instance creation has been added that allows one
873 to "adopt" currently existing logical volumes, with data
874 preservation. This should allow easier migration to Ganeti from
875 unmanaged (or managed via other software) instances.
877 Another disk improvement is the possibility to convert between redundant
878 (DRBD) and plain (LVM) disk configuration for an instance. This should
879 allow better scalability (starting with one node and growing the
880 cluster, or shrinking a two-node cluster to one node).
882 A new feature that could help with automated node failovers has been
883 implemented: if a node sees itself as offline (by querying the master
884 candidates), it will try to shutdown (hard) all instances and any active
885 DRBD devices. This reduces the risk of duplicate instances if an
886 external script automatically failovers the instances on such nodes. To
887 enable this, the cluster parameter ``maintain_node_health`` should be
888 enabled; in the future this option (per the name) will enable other
889 automatic maintenance features.
891 Instance export/import now will reuse the original instance
892 specifications for all parameters; that means exporting an instance,
893 deleting it and the importing it back should give an almost identical
894 instance. Note that the default import behaviour has changed from
895 before, where it created only one NIC; now it recreates the original
898 Cluster verify has added a few new checks: SSL certificates validity,
899 /etc/hosts consistency across the cluster, etc.
904 As usual, many internal changes were done, documentation fixes,
907 - Fixed cluster initialization with disabled cluster storage (regression
909 - File-based storage supports growing the disks
910 - Fixed behaviour of node role changes
911 - Fixed cluster verify for some corner cases, plus a general rewrite of
912 cluster verify to allow future extension with more checks
913 - Fixed log spamming by watcher and node daemon (regression introduced
915 - Fixed possible validation issues when changing the list of enabled
917 - Fixed cleanup of /etc/hosts during node removal
918 - Fixed RAPI response for invalid methods
919 - Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
920 - Multiple small improvements to the KVM hypervisor (VNC usage, booting
921 from ide disks, etc.)
922 - Allow OS changes without re-installation (to record a changed OS
923 outside of Ganeti, or to allow OS renames)
924 - Allow instance creation without OS installation (useful for example if
925 the OS will be installed manually, or restored from a backup not in
927 - Implemented option to make cluster ``copyfile`` use the replication
929 - Added list of enabled hypervisors to ssconf (possibly useful for
931 - Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
933 - A partial form of node re-IP is possible via node readd, which now
934 allows changed node primary IP
935 - Command line utilities now show an informational message if the job is
937 - The logs of the master daemon now show the PID/UID/GID of the
944 *(Released Fri, 12 Mar 2010)*
946 During the 2.1.0 long release candidate cycle, a lot of improvements and
947 changes have accumulated with were released later as 2.1.1.
952 The node evacuate command (``gnt-node evacuate``) was significantly
953 rewritten, and as such the IAllocator protocol was changed - a new
954 request type has been added. This unfortunate change during a stable
955 series is designed to improve performance of node evacuations; on
956 clusters with more than about five nodes and which are well-balanced,
957 evacuation should proceed in parallel for all instances of the node
958 being evacuated. As such, any existing IAllocator scripts need to be
959 updated, otherwise the above command will fail due to the unknown
960 request. The provided "dumb" allocator has not been updated; but the
961 ganeti-htools package supports the new protocol since version 0.2.4.
963 Another important change is increased validation of node and instance
964 names. This might create problems in special cases, if invalid host
965 names are being used.
967 Also, a new layer of hypervisor parameters has been added, that sits at
968 OS level between the cluster defaults and the instance ones. This allows
969 customisation of virtualization parameters depending on the installed
970 OS. For example instances with OS 'X' may have a different KVM kernel
971 (or any other parameter) than the cluster defaults. This is intended to
972 help managing a multiple OSes on the same cluster, without manual
973 modification of each instance's parameters.
975 A tool for merging clusters, ``cluster-merge``, has been added in the
981 - Improved the int/float conversions that should make the code more
982 robust in face of errors from the node daemons
983 - Fixed the remove node code in case of internal configuration errors
984 - Fixed the node daemon behaviour in face of inconsistent queue
985 directory (e.g. read-only file-system where we can't open the files
987 - Fixed the behaviour of gnt-node modify for master candidate demotion;
988 now it either aborts cleanly or, if given the new "auto_promote"
989 parameter, will automatically promote other nodes as needed
990 - Fixed compatibility with (unreleased yet) Python 2.6.5 that would
991 completely prevent Ganeti from working
992 - Fixed bug for instance export when not all disks were successfully
994 - Fixed behaviour of node add when the new node is slow in starting up
996 - Fixed handling of signals in the LUXI client, which should improve
997 behaviour of command-line scripts
998 - Added checks for invalid node/instance names in the configuration (now
999 flagged during cluster verify)
1000 - Fixed watcher behaviour for disk activation errors
1001 - Fixed two potentially endless loops in http library, which led to the
1002 RAPI daemon hanging and consuming 100% CPU in some cases
1003 - Fixed bug in RAPI daemon related to hashed passwords
1004 - Fixed bug for unintended qemu-level bridging of multi-NIC KVM
1006 - Enhanced compatibility with non-Debian OSes, but not using absolute
1007 path in some commands and allowing customisation of the ssh
1008 configuration directory
1009 - Fixed possible future issue with new Python versions by abiding to the
1010 proper use of ``__slots__`` attribute on classes
1011 - Added checks that should prevent directory traversal attacks
1012 - Many documentation fixes based on feedback from users
1017 - Added an "early_release" more for instance replace disks and node
1018 evacuate, where we release locks earlier and thus allow higher
1019 parallelism within the cluster
1020 - Added watcher hooks, intended to allow the watcher to restart other
1021 daemons (e.g. from the ganeti-nbma project), but they can be used of
1022 course for any other purpose
1023 - Added a compile-time disable for DRBD barriers, to increase
1024 performance if the administrator trusts the power supply or the
1025 storage system to not lose writes
1026 - Added the option of using syslog for logging instead of, or in
1027 addition to, Ganeti's own log files
1028 - Removed boot restriction for paravirtual NICs for KVM, recent versions
1029 can indeed boot from a paravirtual NIC
1030 - Added a generic debug level for many operations; while this is not
1031 used widely yet, it allows one to pass the debug value all the way to
1033 - Enhanced the hooks environment for instance moves (failovers,
1034 migrations) where the primary/secondary nodes changed during the
1035 operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
1036 - Enhanced data validations for many user-supplied values; one important
1037 item is the restrictions imposed on instance and node names, which
1038 might reject some (invalid) host names
1039 - Add a configure-time option to disable file-based storage, if it's not
1040 needed; this allows greater security separation between the master
1041 node and the other nodes from the point of view of the inter-node RPC
1043 - Added user notification in interactive tools if job is waiting in the
1044 job queue or trying to acquire locks
1045 - Added log messages when a job is waiting for locks
1046 - Added filtering by node tags in instance operations which admit
1047 multiple instances (start, stop, reboot, reinstall)
1048 - Added a new tool for cluster mergers, ``cluster-merge``
1049 - Parameters from command line which are of the form ``a=b,c=d`` can now
1050 use backslash escapes to pass in values which contain commas,
1051 e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
1053 - For KVM, the instance name is the first parameter passed to KVM, so
1054 that it's more visible in the process list
1060 *(Released Tue, 2 Mar 2010)*
1062 Ganeti 2.1 brings many improvements with it. Major changes:
1064 - Added infrastructure to ease automated disk repairs
1065 - Added new daemon to export configuration data in a cheaper way than
1066 using the remote API
1067 - Instance NICs can now be routed instead of being associated with a
1069 - Improved job locking logic to reduce impact of jobs acquiring multiple
1070 locks waiting for other long-running jobs
1072 In-depth implementation details can be found in the Ganeti 2.1 design
1078 - Added chroot hypervisor
1079 - Added more options to xen-hvm hypervisor (``kernel_path`` and
1081 - Added more options to xen-pvm hypervisor (``use_bootloader``,
1082 ``bootloader_path`` and ``bootloader_args``)
1083 - Added the ``use_localtime`` option for the xen-hvm and kvm
1084 hypervisors, and the default value for this has changed to false (in
1085 2.0 xen-hvm always enabled it)
1086 - Added luxi call to submit multiple jobs in one go
1087 - Added cluster initialization option to not modify ``/etc/hosts``
1089 - Added network interface parameters
1090 - Added dry run mode to some LUs
1091 - Added RAPI resources:
1093 - ``/2/instances/[instance_name]/info``
1094 - ``/2/instances/[instance_name]/replace-disks``
1095 - ``/2/nodes/[node_name]/evacuate``
1096 - ``/2/nodes/[node_name]/migrate``
1097 - ``/2/nodes/[node_name]/role``
1098 - ``/2/nodes/[node_name]/storage``
1099 - ``/2/nodes/[node_name]/storage/modify``
1100 - ``/2/nodes/[node_name]/storage/repair``
1102 - Added OpCodes to evacuate or migrate all instances on a node
1103 - Added new command to list storage elements on nodes (``gnt-node
1104 list-storage``) and modify them (``gnt-node modify-storage``)
1105 - Added new ssconf files with master candidate IP address
1106 (``ssconf_master_candidates_ips``), node primary IP address
1107 (``ssconf_node_primary_ips``) and node secondary IP address
1108 (``ssconf_node_secondary_ips``)
1109 - Added ``ganeti-confd`` and a client library to query the Ganeti
1110 configuration via UDP
1111 - Added ability to run hooks after cluster initialization and before
1113 - Added automatic mode for disk replace (``gnt-instance replace-disks
1115 - Added ``gnt-instance recreate-disks`` to re-create (empty) disks
1116 after catastrophic data-loss
1117 - Added ``gnt-node repair-storage`` command to repair damaged LVM volume
1119 - Added ``gnt-instance move`` command to move instances

1122 - Added new job status field ``lock_status``
1123 - Added parseable error codes to cluster verification (``gnt-cluster
1124 verify --error-codes``) and made output less verbose (use
1125 ``--verbose`` to restore previous behaviour)
1126 - Added UUIDs to the main config entities (cluster, nodes, instances)
1127 - Added support for OS variants
1128 - Added support for hashed passwords in the Ganeti remote API users file
1130 - Added option to specify maximum timeout on instance shutdown
1131 - Added ``--no-ssh-init`` option to ``gnt-cluster init``
1132 - Added new helper script to start and stop Ganeti daemons
1133 (``daemon-util``), with the intent to reduce the work necessary to
1134 adjust Ganeti for non-Debian distributions and to start/stop daemons
1136 - Added more unittests
1137 - Fixed critical bug in ganeti-masterd startup
1138 - Removed the configure-time ``kvm-migration-port`` parameter, this is
1139 now customisable at the cluster level for both the KVM and Xen
1140 hypervisors using the new ``migration_port`` parameter
1141 - Pass ``INSTANCE_REINSTALL`` variable to OS installation script when
1142 reinstalling an instance
1143 - Allowed ``@`` in tag names

1164 - Fix a string formatting bug
1165 - Improve safety of the code in some error paths
1166 - Improve data validation in the master of values returned from nodes
1172 *(Released Thu, 17 Dec 2009)*
1174 - Fix security issue due to missing validation of iallocator names; this
1175 allows local and remote execution of arbitrary executables
1176 - Fix failure of gnt-node list during instance removal
1177 - Ship the RAPI documentation in the archive
1183 *(Released Wed, 30 Sep 2009)*
1185 - Fixed many wrong messages
1186 - Fixed a few bugs related to the locking library
1187 - Fixed MAC checking at instance creation time
1188 - Fixed a DRBD parsing bug related to gaps in /proc/drbd
1189 - Fixed a few issues related to signal handling in both daemons and
1191 - Fixed the example startup script provided
1192 - Fixed insserv dependencies in the example startup script (patch from
1194 - Fixed handling of drained nodes in the iallocator framework
1195 - Fixed handling of KERNEL_PATH parameter for xen-hvm (Debian bug
1197 - Fixed error related to invalid job IDs in job polling
1198 - Fixed job/opcode persistence on unclean master shutdown
1199 - Fixed handling of partial job processing after unclean master
1201 - Fixed error reporting from LUs, previously all errors were converted
1202 into execution errors
1203 - Fixed error reporting from burnin
1204 - Decreased significantly the memory usage of the job queue
1205 - Optimised slightly multi-job submission
1206 - Optimised slightly opcode loading
1207 - Backported the multi-job submit framework from the development
1208 branch; multi-instance start and stop should be faster
1209 - Added script to clean archived jobs after 21 days; this will reduce
1210 the size of the queue directory
1211 - Added some extra checks in disk size tracking
1212 - Added an example ethers hook script
1213 - Added a cluster parameter that prevents Ganeti from modifying of
1215 - Added more node information to RAPI responses
1216 - Added a ``gnt-job watch`` command that allows following the ouput of a
1218 - Added a bind-address option to ganeti-rapi
1219 - Added more checks to the configuration verify
1220 - Enhanced the burnin script such that some operations can be retried
1222 - Converted instance reinstall to multi-instance model
1228 *(Released Fri, 7 Aug 2009)*
1230 - Added ``--ignore-size`` to the ``gnt-instance activate-disks`` command
1231 to allow using the pre-2.0.2 behaviour in activation, if any existing
1232 instances have mismatched disk sizes in the configuration
1233 - Added ``gnt-cluster repair-disk-sizes`` command to check and update
1234 any configuration mismatches for disk sizes
1235 - Added ``gnt-master cluste-failover --no-voting`` to allow master
1236 failover to work on two-node clusters
1237 - Fixed the ``--net`` option of ``gnt-backup import``, which was
1239 - Fixed detection of OS script errors in ``gnt-backup export``
1240 - Fixed exit code of ``gnt-backup export``
1246 *(Released Fri, 17 Jul 2009)*
1248 - Added experimental support for stripped logical volumes; this should
1249 enhance performance but comes with a higher complexity in the block
1250 device handling; stripping is only enabled when passing
1251 ``--with-lvm-stripecount=N`` to ``configure``, but codepaths are
1252 affected even in the non-stripped mode
1253 - Improved resiliency against transient failures at the end of DRBD
1254 resyncs, and in general of DRBD resync checks
1255 - Fixed a couple of issues with exports and snapshot errors
1256 - Fixed a couple of issues in instance listing
1257 - Added display of the disk size in ``gnt-instance info``
1258 - Fixed checking for valid OSes in instance creation
1259 - Fixed handling of the "vcpus" parameter in instance listing and in
1260 general of invalid parameters
1261 - Fixed http server library, and thus RAPI, to handle invalid
1262 username/password combinations correctly; this means that now they
1263 report unauthorized for queries too, not only for modifications,
1264 allowing earlier detect of configuration problems
1265 - Added a new "role" node list field, equivalent to the master/master
1266 candidate/drained/offline flags combinations
1267 - Fixed cluster modify and changes of candidate pool size
1268 - Fixed cluster verify error messages for wrong files on regular nodes
1269 - Fixed a couple of issues with node demotion from master candidate role
1270 - Fixed node readd issues
1271 - Added non-interactive mode for ``ganeti-masterd --no-voting`` startup
1272 - Added a new ``--no-voting`` option for masterfailover to fix failover
1273 on two-nodes clusters when the former master node is unreachable
1274 - Added instance reinstall over RAPI
1280 *(Released Tue, 16 Jun 2009)*
1282 - added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
1283 allow re-adding the start in single-user option (regression from 1.2)
1284 - the watcher writes the instance status to a file, to allow monitoring
1285 to report the instance status (from the master) based on cached
1286 results of the watcher's queries; while this can get stale if the
1287 watcher is being locked due to other work on the cluster, this is
1288 still an improvement
1289 - the watcher now also restarts the node daemon and the rapi daemon if
1291 - fixed the watcher to handle full and drained queue cases
1292 - hooks export more instance data in the environment, which helps if
1293 hook scripts need to take action based on the instance's properties
1294 (no longer need to query back into ganeti)
1295 - instance failovers when the instance is stopped do not check for free
1296 RAM, so that failing over a stopped instance is possible in low memory
1298 - rapi uses queries for tags instead of jobs (for less job traffic), and
1299 for cluster tags it won't talk to masterd at all but read them from
1301 - a couple of error handling fixes in RAPI
1302 - drbd handling: improved the error handling of inconsistent disks after
1303 resync to reduce the frequency of "there are some degraded disks for
1304 this instance" messages
1305 - fixed a bug in live migration when DRBD doesn't want to reconnect (the
1306 error handling path called a wrong function name)
1312 *(Released Wed, 27 May 2009)*
1314 - no changes from rc5
1317 Version 2.0 release candidate 5
1318 -------------------------------
1320 *(Released Wed, 20 May 2009)*
1322 - fix a couple of bugs (validation, argument checks)
1323 - fix ``gnt-cluster getmaster`` on non-master nodes (regression)
1324 - some small improvements to RAPI and IAllocator
1325 - make watcher automatically start the master daemon if down
1328 Version 2.0 release candidate 4
1329 -------------------------------
1331 *(Released Mon, 27 Apr 2009)*
1333 - change the OS list to not require locks; this helps with big clusters
1334 - fix ``gnt-cluster verify`` and ``gnt-cluster verify-disks`` when the
1335 volume group is broken
1336 - ``gnt-instance info``, without any arguments, doesn't run for all
1337 instances anymore; either pass ``--all`` or pass the desired
1338 instances; this helps against mistakes on big clusters where listing
1339 the information for all instances takes a long time
1340 - miscellaneous doc and man pages fixes
1343 Version 2.0 release candidate 3
1344 -------------------------------
1346 *(Released Wed, 8 Apr 2009)*
1348 - Change the internal locking model of some ``gnt-node`` commands, in
1349 order to reduce contention (and blocking of master daemon) when
1350 batching many creation/reinstall jobs
1351 - Fixes to Xen soft reboot
1352 - No longer build documentation at build time, instead distribute it in
1353 the archive, in order to reduce the need for the whole docbook/rst
1357 Version 2.0 release candidate 2
1358 -------------------------------
1360 *(Released Fri, 27 Mar 2009)*
1362 - Now the cfgupgrade scripts works and can upgrade 1.2.7 clusters to 2.0
1363 - Fix watcher startup sequence, improves the behaviour of busy clusters
1364 - Some other fixes in ``gnt-cluster verify``, ``gnt-instance
1365 replace-disks``, ``gnt-instance add``, ``gnt-cluster queue``, KVM VNC
1366 bind address and other places
1367 - Some documentation fixes and updates
1370 Version 2.0 release candidate 1
1371 -------------------------------
1373 *(Released Mon, 2 Mar 2009)*
1375 - More documentation updates, now all docs should be more-or-less
1377 - A couple of small fixes (mixed hypervisor clusters, offline nodes,
1379 - Added a customizable HV_KERNEL_ARGS hypervisor parameter (for Xen PVM
1381 - Fix an issue related to $libdir/run/ganeti and cluster creation
1387 *(Released Thu, 19 Feb 2009)*
1389 - Xen PVM and KVM have switched the default value for the instance root
1390 disk to the first partition on the first drive, instead of the whole
1391 drive; this means that the OS installation scripts must be changed
1393 - Man pages have been updated
1394 - RAPI has been switched by default to HTTPS, and the exported functions
1395 should all work correctly
1396 - RAPI v1 has been removed
1397 - Many improvements to the KVM hypervisor
1398 - Block device errors are now better reported
1399 - Many other bugfixes and small improvements
1405 *(Released Mon, 26 Jan 2009)*
1407 - Version 2 is a general rewrite of the code and therefore the
1408 differences are too many to list, see the design document for 2.0 in
1409 the ``doc/`` subdirectory for more details
1410 - In this beta version there is not yet a migration path from 1.2 (there
1411 will be one in the final 2.0 release)
1412 - A few significant changes are:
1414 - all commands are executed by a daemon (``ganeti-masterd``) and the
1415 various ``gnt-*`` commands are just front-ends to it
1416 - all the commands are entered into, and executed from a job queue,
1417 see the ``gnt-job(8)`` manpage
1418 - the RAPI daemon supports read-write operations, secured by basic
1419 HTTP authentication on top of HTTPS
1420 - DRBD version 0.7 support has been removed, DRBD 8 is the only
1421 supported version (when migrating from Ganeti 1.2 to 2.0, you need
1422 to migrate to DRBD 8 first while still running Ganeti 1.2)
1423 - DRBD devices are using statically allocated minor numbers, which
1424 will be assigned to existing instances during the migration process
1425 - there is support for both Xen PVM and Xen HVM instances running on
1427 - KVM virtualization is supported too
1428 - file-based storage has been implemented, which means that it is
1429 possible to run the cluster without LVM and DRBD storage, for
1430 example using a shared filesystem exported from shared storage (and
1431 still have live migration)
1437 *(Released Tue, 13 Jan 2009)*
1439 - Change the default reboot type in ``gnt-instance reboot`` to "hard"
1440 - Reuse the old instance mac address by default on instance import, if
1441 the instance name is the same.
1442 - Handle situations in which the node info rpc returns incomplete
1444 - Add checks for tcp/udp ports collisions in ``gnt-cluster verify``
1445 - Improved version of batcher:
1447 - state file support
1448 - instance mac address support
1449 - support for HVM clusters/instances
1451 - Add an option to show the number of cpu sockets and nodes in
1453 - Support OSes that handle more than one version of the OS api (but do
1454 not change the current API in any other way)
1455 - Fix ``gnt-node migrate``
1456 - ``gnt-debug`` man page
1457 - Fixes various more typos and small issues
1458 - Increase disk resync maximum speed to 60MB/s (from 30MB/s)
1464 *(Released Wed, 24 Sep 2008)*
1466 - new ``--hvm-nic-type`` and ``--hvm-disk-type`` flags to control the
1467 type of disk exported to fully virtualized instances.
1468 - provide access to the serial console of HVM instances
1469 - instance auto_balance flag, set by default. If turned off it will
1470 avoid warnings on cluster verify if there is not enough memory to fail
1471 over an instance. in the future it will prevent automatically failing
1472 it over when we will support that.
1473 - batcher tool for instance creation, see ``tools/README.batcher``
1474 - ``gnt-instance reinstall --select-os`` to interactively select a new
1475 operating system when reinstalling an instance.
1476 - when changing the memory amount on instance modify a check has been
1477 added that the instance will be able to start. also warnings are
1478 emitted if the instance will not be able to fail over, if auto_balance
1480 - documentation fixes
1481 - sync fields between ``gnt-instance list/modify/add/import``
1482 - fix a race condition in drbd when the sync speed was set after giving
1483 the device a remote peer.
1489 *(Released Tue, 22 Jul 2008)*
1491 - note: the allowed size and number of tags per object were reduced
1492 - fix a bug in ``gnt-cluster verify`` with inconsistent volume groups
1493 - fixed twisted 8.x compatibility
1494 - fixed ``gnt-instance replace-disks`` with iallocator
1495 - add TCP keepalives on twisted connections to detect restarted nodes
1496 - disk increase support, see ``gnt-instance grow-disk``
1497 - implement bulk node/instance query for RAPI
1498 - add tags in node/instance listing (optional)
1499 - experimental migration (and live migration) support, read the man page
1500 for ``gnt-instance migrate``
1501 - the ``ganeti-watcher`` logs are now timestamped, and the watcher also
1502 has some small improvements in handling its state file
1508 *(Released Fri, 13 Jun 2008)*
1510 - Experimental readonly, REST-based remote API implementation;
1511 automatically started on master node, TCP port 5080, if enabled by
1512 ``--enable-rapi`` parameter to configure script.
1513 - Instance allocator support. Add and import instance accept a
1514 ``--iallocator`` parameter, and call that instance allocator to decide
1515 which node to use for the instance. The iallocator document describes
1516 what's expected from an allocator script.
1517 - ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
1518 ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
1519 node is lost there is still enough memory to fail over the instances
1521 - ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
1522 ``gnt-cluster verify``, to check for site-specific compliance. All the
1523 hooks will run, and their output, if any, will be displayed. Any
1524 failing hook will make the verification return an error value.
1525 - ``gnt-cluster verify`` now checks that its peers are reachable on the
1526 primary and secondary interfaces
1527 - ``gnt-node add`` now supports the ``--readd`` option, to readd a node
1528 that is still declared as part of the cluster and has failed.
1529 - ``gnt-* list`` commands now accept a new ``-o +field`` way of
1530 specifying output fields, that just adds the chosen fields to the
1532 - ``gnt-backup`` now has a new ``remove`` command to delete an existing
1533 export from the filesystem.
1534 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
1535 have been added. Using them you can enable/disable acpi and pae
1536 support, and specify a path for a cd image to be exported to the
1537 instance. These parameters as the name suggest only work on HVM
1539 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
1540 PAE support will be set to the previously hardcoded values, but the
1541 (previously hardcoded) path to the CDROM ISO image will be unset and
1542 if required, needs to be set manually with ``gnt-instance modify``
1544 - The address to which an instance's VNC console is bound is now
1545 selectable per-instance, rather than being cluster wide. Of course
1546 this only applies to instances controlled via VNC, so currently just
1547 applies to HVM clusters.
1553 *(Released Mon, 18 Feb 2008)*
1555 - more tweaks to the disk activation code (especially helpful for DRBD)
1556 - change the default ``gnt-instance list`` output format, now there is
1557 one combined status field (see the manpage for the exact values this
1559 - some more fixes for the mac export to hooks change
1560 - make Ganeti not break with DRBD 8.2.x (which changed the version
1561 format in ``/proc/drbd``) (issue 24)
1562 - add an upgrade tool from "remote_raid1" disk template to "drbd" disk
1563 template, allowing migration from DRBD0.7+MD to DRBD8
1569 *(Released Wed, 30 Jan 2008)*
1571 - fix ``gnt-instance modify`` breakage introduced in 1.2.1 with the HVM
1573 - add command aliases infrastructure and a few aliases
1574 - allow listing of VCPUs in the ``gnt-instance list`` and improve the
1575 man pages and the ``--help`` option of ``gnt-node
1576 list``/``gnt-instance list``
1577 - fix ``gnt-backup list`` with down nodes (issue 21)
1578 - change the tools location (move from $pkgdatadir to $pkglibdir/tools)
1579 - fix the dist archive and add a check for including svn/git files in
1581 - some developer-related changes: improve the burnin and the QA suite,
1582 add an upload script for testing during development
1588 *(Released Wed, 16 Jan 2008)*
1590 - experimental HVM support, read the install document, section
1591 "Initializing the cluster"
1592 - allow for the PVM hypervisor per-instance kernel and initrd paths
1593 - add a new command ``gnt-cluster verify-disks`` which uses a new
1594 algorithm to improve the reconnection of the DRBD pairs if the device
1595 on the secondary node has gone away
1596 - make logical volume code auto-activate LVs at disk activation time
1597 - slightly improve the speed of activating disks
1598 - allow specification of the MAC address at instance creation time, and
1599 changing it later via ``gnt-instance modify``
1600 - fix handling of external commands that generate lots of output on
1602 - update documentation with regard to minimum version of DRBD8 supported
1608 *(Released Tue, 4 Dec 2007)*
1610 - Log the ``xm create`` output to the node daemon log on failure (to
1611 help diagnosing the error)
1612 - In debug mode, log all external commands output if failed to the logs
1613 - Change parsing of lvm commands to ignore stderr
1619 *(Released Wed, 28 Nov 2007)*
1621 - Another round of updates to the DRBD 8 code to deal with more failures
1622 in the replace secondary node operation
1623 - Some more logging of failures in disk operations (lvm, drbd)
1624 - A few documentation updates
1631 *(Released Tue, 13 Nov 2007)*
1633 - Change configuration file format from Python's Pickle to JSON.
1634 Upgrading is possible using the cfgupgrade utility.
1635 - Add support for DRBD 8.0 (new disk template ``drbd``) which allows for
1636 faster replace disks and is more stable (DRBD 8 has many improvements
1637 compared to DRBD 0.7)
1638 - Added command line tags support (see man pages for ``gnt-instance``,
1639 ``gnt-node``, ``gnt-cluster``)
1640 - Added instance rename support
1641 - Added multi-instance startup/shutdown
1642 - Added cluster rename support
1643 - Added ``gnt-node evacuate`` to simplify some node operations
1644 - Added instance reboot operation that can speedup reboot as compared to
1646 - Soften the requirement that hostnames are in FQDN format
1647 - The ``ganeti-watcher`` now activates drbd pairs after secondary node
1649 - Removed dependency on debian's patched fping that uses the
1650 non-standard ``-S`` option
1651 - Now the OS definitions are searched for in multiple, configurable
1652 paths (easier for distros to package)
1653 - Some changes to the hooks infrastructure (especially the new
1654 post-configuration update hook)
1655 - Other small bugfixes
