The default disk template will be taken from the list of + enabled disk templates. +- The monitoring daemon is now running as root, in order to be able to collect + information only available to root (such as the state of Xen instances). +- The ConfD client is now IPv6 compatible. +- File and shared file storage is no longer dis/enabled at configure time, + but using the option '--enabled-disk-templates' at cluster initialization and + modification. +- The default directories for file and shared file storage are not anymore + specified at configure time, but taken from the cluster's configuration. + They can be set at cluster initialization and modification with + '--file-storage-dir' and '--shared-file-storage-dir'. +- Cluster verification now includes stricter checks regarding the + default file and shared file storage directories. It now checks that + the directories are explicitely allowed in the 'file-storage-paths' file and + that the directories exist on all nodes. +- The list of allowed disk templates in the instance policy and the list + of cluster-wide enabled disk templates is now checked for consistency + on cluster or group modification. On cluster initialization, the ipolicy + disk templates are ensured to be a subset of the cluster-wide enabled + disk templates. + +New features +~~~~~~~~~~~~ + +- DRBD 8.4 support. Depending on the installed DRBD version, Ganeti now uses + the correct command syntax. It is possible to use different DRBD versions + on different nodes as long as they are compatible to each other. This + enables rolling upgrades of DRBD with no downtime. As permanent operation + of different DRBD versions within a node group is discouraged, + ``gnt-cluster verify`` will emit a warning if it detects such a situation. +- New "inst-status-xen" data collector for the monitoring daemon, providing + information about the state of the xen instances on the nodes. +- New "lv" data collector for the monitoring daemon, collecting data about the + logical volumes on the nodes, and pairing them with the name of the instances + they belong to. +- New "diskstats" data collector, collecting the data from /proc/diskstats and + presenting them over the monitoring daemon interface. +- The ConfD client is now IPv6 compatible. + +New dependencies +~~~~~~~~~~~~~~~~ +The following new dependencies have been added. + +Python + +- ``python-mock`` (http://www.voidspace.org.uk/python/mock/) is now a required + for the unit tests (and only used for testing). + +Haskell + +- ``hslogger`` (http://software.complete.org/hslogger) is now always + required, even if confd is not enabled. + +Since 2.9.0 beta1 +~~~~~~~~~~~~~~~~~ + +- various bug fixes +- update of the documentation, in particular installation instructions +- merging of LD_* constants into DT_* constants +- python style changes to be compatible with newer versions of pylint + + +Version 2.9.0 beta1 +------------------- + +*(Released Thu, 29 Aug 2013)* + +This was the first beta release of the 2.9 series. All important changes +are listed in the latest 2.9 entry. + + +Version 2.8.0 +------------- + +*(Released Mon, 30 Sep 2013)* + +Incompatible/important changes +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- Instance policy can contain multiple instance specs, as described in + the “Constrained instance sizes” section of :doc:`Partitioned Ganeti + `. As a consequence, it's not possible to partially change + or override instance specs. Bounding specs (min and max) can be specified as a + whole using the new option ``--ipolicy-bounds-specs``, while standard + specs use the new option ``--ipolicy-std-specs``. +- The output of the info command of gnt-cluster, gnt-group, gnt-node, + gnt-instance is a valid YAML object. +- hail now honors network restrictions when allocating nodes. This led to an + update of the IAllocator protocol. See the IAllocator documentation for + details. +- confd now only answers static configuration request over the network. luxid + was extracted, listens on the local LUXI socket and responds to live queries. + This allows finer grained permissions if using separate users. + +New features +~~~~~~~~~~~~ + +- The :doc:`Remote API ` daemon now supports a command line flag + to always require authentication, ``--require-authentication``. It can + be specified in ``$sysconfdir/default/ganeti``. +- A new cluster attribute 'enabled_disk_templates' is introduced. It will + be used to manage the disk templates to be used by instances in the cluster. + Initially, it will be set to a list that includes plain, drbd, if they were + enabled by specifying a volume group name, and file and sharedfile, if those + were enabled at configure time. Additionally, it will include all disk + templates that are currently used by instances. The order of disk templates + will be based on Ganeti's history of supporting them. In the future, the + first entry of the list will be used as a default disk template on instance + creation. +- ``cfgupgrade`` now supports a ``--downgrade`` option to bring the + configuration back to the previous stable version. +- Disk templates in group ipolicy can be restored to the default value. +- Initial support for diskless instances and virtual clusters in QA. +- More QA and unit tests for instance policies. +- Every opcode now contains a reason trail (visible through ``gnt-job info``) + describing why the opcode itself was executed. +- The monitoring daemon is now available. It allows users to query the cluster + for obtaining information about the status of the system. The daemon is only + responsible for providing the information over the network: the actual data + gathering is performed by data collectors (currently, only the DRBD status + collector is available). +- In order to help developers work on Ganeti, a new script + (``devel/build_chroot``) is provided, for building a chroot that contains all + the required development libraries and tools for compiling Ganeti on a Debian + Squeeze system. +- A new tool, ``harep``, for performing self-repair and recreation of instances + in Ganeti has been added. +- Split queries are enabled for tags, network, exports, cluster info, groups, + jobs, nodes. +- New command ``show-ispecs-cmd`` for ``gnt-cluster`` and ``gnt-group``. + It prints the command line to set the current policies, to ease + changing them. +- Add the ``vnet_hdr`` HV parameter for KVM, to control whether the tap + devices for KVM virtio-net interfaces will get created with VNET_HDR + (IFF_VNET_HDR) support. If set to false, it disables offloading on the + virtio-net interfaces, which prevents host kernel tainting and log + flooding, when dealing with broken or malicious virtio-net drivers. + It's set to true by default. +- Instance failover now supports a ``--cleanup`` parameter for fixing previous + failures. +- Support 'viridian' parameter in Xen HVM +- Support DSA SSH keys in bootstrap +- To simplify the work of packaging frameworks that want to add the needed users + and groups in a split-user setup themselves, at build time three files in + ``doc/users`` will be generated. The ``groups`` files contains, one per line, + the groups to be generated, the ``users`` file contains, one per line, the + users to be generated, optionally followed by their primary group, where + important. The ``groupmemberships`` file contains, one per line, additional + user-group membership relations that need to be established. The syntax of + these files will remain stable in all future versions. + + +New dependencies +~~~~~~~~~~~~~~~~ +The following new dependencies have been added: + +For Haskell: +- The ``curl`` library is not optional anymore for compiling the Haskell code. +- ``snap-server`` library (if monitoring is enabled). + +For Python: +- The minimum Python version needed to run Ganeti is now 2.6. +- ``yaml`` library (only for running the QA). + +Since 2.8.0 rc3 +~~~~~~~~~~~~~~~ +- Perform proper cleanup on termination of Haskell daemons +- Fix corner-case in handling of remaining retry time + + +Version 2.8.0 rc3 +----------------- + +*(Released Tue, 17 Sep 2013)* + +- To simplify the work of packaging frameworks that want to add the needed users + and groups in a split-user setup themselves, at build time three files in + ``doc/users`` will be generated.
