Important change: the internal RPC mechanism between Ganeti nodes has
changed from using a home-grown http library (based on the Python base
libraries) to use the PycURL library. This requires that PycURL is
installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
against GnuTLS by default. cURL's support for GnuTLS had known issues
before cURL 7.21.0 and we recommend using the latest cURL release or
linking against OpenSSL. Most other distributions already link PycURL
and cURL against OpenSSL. The command::

  python -c 'import pycurl; print pycurl.version'

can be used to determine the libraries PycURL and cURL are linked
against.

Other significant changes:

- Rewrote much of the internals of the job queue, in order to achieve
  better parallelism; this decouples job query operations from the job
  processing, and it should allow much nicer behaviour of the master
  daemon under load, and it also has uncovered some long-standing bugs
  related to the job serialisation (now fixed)
- Added a default iallocator setting to the cluster parameters,
  eliminating the need to always pass nodes or an iallocator for
  operations that require selection of new node(s)
- Added experimental support for the LXC virtualization method
- Added support for OS parameters, which allows the installation of
  instances to pass parameter to OS scripts in order to customise the
  instance
- Added a hypervisor parameter controlling the migration type (live or
  non-live), since hypervisors have various levels of reliability; this
  has renamed the 'live' parameter to 'mode'
- Added a cluster parameter ``reserved_lvs`` that denotes reserved
  logical volumes, meaning that cluster verify will ignore them and not
  flag their presence as errors
- The watcher will now reset the error count for failed instances after
  8 hours, thus allowing self-healing if the problem that caused the
  instances to be down/fail to start has cleared in the meantime
- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
  check for, and warn, if the drbd module parameter ``usermode_helper``
  is not consistent with the cluster-wide setting; this is needed to
  make diagnose easier of failed drbd creations
- Started adding base IPv6 support, but this is not yet
  enabled/available for use
- Rename operations (cluster, instance) will now return the new name,
  which is especially useful if a short name was passed in
- Added support for instance migration in RAPI
- Added a tool to pre-configure nodes for the SSH setup, before joining
  them to the cluster; this will allow in the future a simplified model
  for node joining (but not yet fully enabled in 2.2); this needs the
  paramiko python library
- Fixed handling of name-resolving errors
- Fixed consistency of job results on the error path
- Fixed master-failover race condition when executed multiple times in
  sequence
- Fixed many bugs related to the job queue (mostly introduced during the
  2.2 development cycle, so not all are impacting 2.1)
- Fixed instance migration with missing disk symlinks
- Fixed handling of unknown jobs in ``gnt-job archive``
- And many other small fixes/improvements

Internal changes:

- Enhanced both the unittest and the QA coverage
- Switched the opcode validation to a generic model, and extended the
  validation to all opcode parameters
- Changed more parts of the code that write shell scripts to use the
  same class for this
- Switched the master daemon to use the asyncore library for the Luxi
  server endpoint

Bugfixes only:
  - Add an option to only select some reboot types during qa/burnin.
    (on some hypervisors consequent reboots are not supported)
  - Fix infrequent race condition in master failover. Sometimes the old
    master ip address would be still detected as up for a short time
    after it was removed, causing failover to fail.
  - Decrease mlockall warnings when the ctypes module is missing. On
    Python 2.4 we support running even if no ctypes module is installed,
    but we were too verbose about this issue.
  - Fix building on old distributions, on which man doesn't have a
    --warnings option.
  - Fix RAPI not to ignore the MAC address on instance creation
  - Implement the old instance creation format in the RAPI client.

A medium sized development cycle. Some new features, and some
fixes/small improvements/cleanups.

Significant features
~~~~~~~~~~~~~~~~~~~~

The node deamon now tries to mlock itself into memory, unless the
``--no-mlock`` flag is passed. It also doesn't fail if it can't write
its logs, and falls back to console logging. This allows emergency
features such as ``gnt-node powercycle`` to work even in the event of a
broken node disk (tested offlining the disk hosting the node's
296
filesystem and dropping its memory caches; don't try this at home)

KVM: add vhost-net acceleration support. It can be tested with a new
enough version of the kernel and of qemu-kvm.

KVM: Add instance chrooting feature. If you use privilege dropping for
your VMs you can also now force them to chroot to an empty directory,
before starting the emulated guest.

KVM: Add maximum migration bandwith and maximum downtime tweaking
support (requires a new-enough version of qemu-kvm).

Cluster verify will now warn if the master node doesn't have the master
ip configured on it.

Add a new (incompatible) instance creation request format to RAPI which
supports all parameters (previously only a subset was supported, and it
wasn't possible to extend the old format to accomodate all the new
features. The old format is still supported, and a client can check for
this feature, before using it, by checking for its presence in the
``features`` RAPI resource.

Now with ancient latin support. Try it passing the ``--roman`` option to
319
320
``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
(requires the python-roman module to be installed, in order to work).

Other changes

As usual many internal code refactorings, documentation updates, and
such. Among others:

  - Lots of improvements and cleanups to the experimental Remote API
    (RAPI) client library.
  - A new unit test suite for the core daemon libraries.
  - A fix to creating missing directories makes sure the umask is not
    applied anymore. This enforces the same directory permissions
    everywhere.
  - Better handling terminating daemons with ctrl+c (used when running
    them in debugging mode).
  - Fix a race condition in live migrating a KVM instance, when stat()
    on the old proc status file returned EINVAL, which is an unexpected
    value.

  - Fixed manpage checking with newer man and utf-8 charachters. But now
    you need the en_US.UTF-8 locale enabled to build Ganeti from git.

Another release with a long development cycle, during which many
different features were added.

Significant features
~~~~~~~~~~~~~~~~~~~~

The KVM hypervisor now can run the individual instances as non-root, to
reduce the impact of a VM being hijacked due to bugs in the
hypervisor. It is possible to run all instances as a single (non-root)
user, to manually specify a user for each instance, or to dynamically
allocate a user out of a cluster-wide pool to each instance, with the
guarantee that no two instances will run under the same user ID on any
given node.

An experimental RAPI client library, that can be used standalone
(without the other Ganeti libraries), is provided in the source tree as
``lib/rapi/client.py``. Note this client might change its interface in
the future, as we iterate on its capabilities.

A new command, ``gnt-cluster renew-crypto`` has been added to easily
replace the cluster's certificates and crypto keys. This might help in
case they have been compromised, or have simply expired.

A new disk option for instance creation has been added that allows one
to "adopt" currently existing logical volumes, with data
preservation. This should allow easier migration to Ganeti from
unmanaged (or managed via other software) instances.

Another disk improvement is the possibility to convert between redundant
(DRBD) and plain (LVM) disk configuration for an instance. This should
allow better scalability (starting with one node and growing the
cluster, or shrinking a two-node cluster to one node).

A new feature that could help with automated node failovers has been
implemented: if a node sees itself as offline (by querying the master
candidates), it will try to shutdown (hard) all instances and any active
DRBD devices. This reduces the risk of duplicate instances if an
external script automatically failovers the instances on such nodes. To
enable this, the cluster parameter ``maintain_node_health`` should be
enabled; in the future this option (per the name) will enable other
automatic maintenance features.

Instance export/import now will reuse the original instance
specifications for all parameters; that means exporting an instance,
deleting it and the importing it back should give an almost identical
instance. Note that the default import behaviour has changed from
before, where it created only one NIC; now it recreates the original
number of NICs.

Cluster verify has added a few new checks: SSL certificates validity,
/etc/hosts consistency across the cluster, etc.

Other changes
~~~~~~~~~~~~~

As usual, many internal changes were done, documentation fixes,
etc. Among others:

- Fixed cluster initialization with disabled cluster storage (regression
  introduced in 2.1.1)
- File-based storage supports growing the disks
- Fixed behaviour of node role changes
- Fixed cluster verify for some corner cases, plus a general rewrite of
  cluster verify to allow future extension with more checks
- Fixed log spamming by watcher and node daemon (regression introduced
  in 2.1.1)
- Fixed possible validation issues when changing the list of enabled
  hypervisors
- Fixed cleanup of /etc/hosts during node removal
- Fixed RAPI response for invalid methods
- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
- Multiple small improvements to the KVM hypervisor (VNC usage, booting
  from ide disks, etc.)
- Allow OS changes without re-installation (to record a changed OS
  outside of Ganeti, or to allow OS renames)
- Allow instance creation without OS installation (useful for example if
  the OS will be installed manually, or restored from a backup not in
  Ganeti format)
- Implemented option to make cluster ``copyfile`` use the replication
  network
- Added list of enabled hypervisors to ssconf (possibly useful for
  external scripts)
- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
  1.2 clusters
- A partial form of node re-IP is possible via node readd, which now
  allows changed node primary IP
- Command line utilities now show an informational message if the job is
  waiting for a lock
- The logs of the master daemon now show the PID/UID/GID of the
  connected client

During the 2.1.0 long release candidate cycle, a lot of improvements and
changes have accumulated with were released later as 2.1.1.

Major changes
~~~~~~~~~~~~~

The node evacuate command (``gnt-node evacuate``) was significantly
rewritten, and as such the IAllocator protocol was changed - a new
request type has been added. This unfortunate change during a stable
series is designed to improve performance of node evacuations; on
clusters with more than about five nodes and which are well-balanced,
evacuation should proceed in parallel for all instances of the node
being evacuated. As such, any existing IAllocator scripts need to be
updated, otherwise the above command will fail due to the unknown
request. The provided "dumb" allocator has not been updated; but the
ganeti-htools package supports the new protocol since version 0.2.4.

Another important change is increased validation of node and instance
names. This might create problems in special cases, if invalid host
names are being used.

Also, a new layer of hypervisor parameters has been added, that sits at
OS level between the cluster defaults and the instance ones. This allows
customisation of virtualization parameters depending on the installed
OS. For example instances with OS 'X' may have a different KVM kernel
(or any other parameter) than the cluster defaults. This is intended to
help managing a multiple OSes on the same cluster, without manual
modification of each instance's parameters.

A tool for merging clusters, ``cluster-merge``, has been added in the
tools sub-directory.

Bug fixes
~~~~~~~~~

- Improved the int/float conversions that should make the code more
  robust in face of errors from the node daemons
- Fixed the remove node code in case of internal configuration errors
- Fixed the node daemon behaviour in face of inconsistent queue
  directory (e.g. read-only file-system where we can't open the files
  read-write, etc.)
- Fixed the behaviour of gnt-node modify for master candidate demotion;
  now it either aborts cleanly or, if given the new “auto_promote”
  parameter, will automatically promote other nodes as needed
- Fixed compatibility with (unreleased yet) Python 2.6.5 that would
  completely prevent Ganeti from working
- Fixed bug for instance export when not all disks were successfully
  exported
- Fixed behaviour of node add when the new node is slow in starting up
  the node daemon
- Fixed handling of signals in the LUXI client, which should improve
  behaviour of command-line scripts
- Added checks for invalid node/instance names in the configuration (now
  flagged during cluster verify)
- Fixed watcher behaviour for disk activation errors
- Fixed two potentially endless loops in http library, which led to the
  RAPI daemon hanging and consuming 100% CPU in some cases
- Fixed bug in RAPI daemon related to hashed passwords
- Fixed bug for unintended qemu-level bridging of multi-NIC KVM
  instances
- Enhanced compatibility with non-Debian OSes, but not using absolute
  path in some commands and allowing customisation of the ssh
  configuration directory
- Fixed possible future issue with new Python versions by abiding to the
  proper use of ``__slots__`` attribute on classes
- Added checks that should prevent directory traversal attacks
- Many documentation fixes based on feedback from users

New features
~~~~~~~~~~~~

- Added an “early_release” more for instance replace disks and node
  evacuate, where we release locks earlier and thus allow higher
  parallelism within the cluster
- Added watcher hooks, intended to allow the watcher to restart other
  daemons (e.g. from the ganeti-nbma project), but they can be used of
  course for any other purpose
- Added a compile-time disable for DRBD barriers, to increase
  performance if the administrator trusts the power supply or the
  storage system to not lose writes
- Added the option of using syslog for logging instead of, or in
  addition to, Ganeti's own log files
- Removed boot restriction for paravirtual NICs for KVM, recent versions
  can indeed boot from a paravirtual NIC
- Added a generic debug level for many operations; while this is not
  used widely yet, it allows one to pass the debug value all the way to
  the OS scripts
- Enhanced the hooks environment for instance moves (failovers,
  migrations) where the primary/secondary nodes changed during the
  operation, by adding {NEW,OLD}_{PRIMARY,SECONDARY} vars
- Enhanced data validations for many user-supplied values; one important
  item is the restrictions imposed on instance and node names, which
  might reject some (invalid) host names
- Add a configure-time option to disable file-based storage, if it's not
  needed; this allows greater security separation between the master
  node and the other nodes from the point of view of the inter-node RPC
  protocol
- Added user notification in interactive tools if job is waiting in the
  job queue or trying to acquire locks
- Added log messages when a job is waiting for locks
- Added filtering by node tags in instance operations which admit
  multiple instances (start, stop, reboot, reinstall)
- Added a new tool for cluster mergers, ``cluster-merge``
- Parameters from command line which are of the form ``a=b,c=d`` can now
  use backslash escapes to pass in values which contain commas,
  e.g. ``a=b\\c,d=e`` where the 'a' parameter would get the value
  ``b,c``
- For KVM, the instance name is the first parameter passed to KVM, so
  that it's more visible in the process list

Ganeti 2.1 brings many improvements with it. Major changes:

- Added infrastructure to ease automated disk repairs
- Added new daemon to export configuration data in a cheaper way than
  using the remote API
- Instance NICs can now be routed instead of being associated with a
  networking bridge
- Improved job locking logic to reduce impact of jobs acquiring multiple
  locks waiting for other long-running jobs

- added ``-H``/``-B`` startup parameters to ``gnt-instance``, which will
  allow re-adding the start in single-user option (regression from 1.2)
- the watcher writes the instance status to a file, to allow monitoring
  to report the instance status (from the master) based on cached
  results of the watcher's queries; while this can get stale if the
  watcher is being locked due to other work on the cluster, this is
  still an improvement
- the watcher now also restarts the node daemon and the rapi daemon if
  they died
- fixed the watcher to handle full and drained queue cases
799

- hooks export more instance data in the environment, which helps if

  ssconf
- a couple of error handling fixes in RAPI
- drbd handling: improved the error handling of inconsistent disks after
  resync to reduce the frequency of "there are some degraded disks for
  this instance" messages
- fixed a bug in live migration when DRBD doesn't want to reconnect (the
  error handling path called a wrong function name)

  drive; this means that the OS installation scripts must be changed
  accordingly
- Man pages have been updated
- RAPI has been switched by default to HTTPS, and the exported functions
  should all work correctly
- RAPI v1 has been removed
- Many improvements to the KVM hypervisor
- Block device errors are now better reported
- Many other bugfixes and small improvements

- Version 2 is a general rewrite of the code and therefore the
  differences are too many to list, see the design document for 2.0 in
  the ``doc/`` subdirectory for more details
- In this beta version there is not yet a migration path from 1.2 (there
  will be one in the final 2.0 release)
- A few significant changes are:

  - all commands are executed by a daemon (``ganeti-masterd``) and the
    various ``gnt-*`` commands are just front-ends to it
923
924
925
926
  - all the commands are entered into, and executed from a job queue,
    see the ``gnt-job(8)`` manpage
  - the RAPI daemon supports read-write operations, secured by basic
    HTTP authentication on top of HTTPS

  - DRBD version 0.7 support has been removed, DRBD 8 is the only
    supported version (when migrating from Ganeti 1.2 to 2.0, you need
    to migrate to DRBD 8 first while still running Ganeti 1.2)
  - DRBD devices are using statically allocated minor numbers, which
    will be assigned to existing instances during the migration process
  - there is support for both Xen PVM and Xen HVM instances running on
    the same cluster
  - KVM virtualization is supported too
  - file-based storage has been implemented, which means that it is
    possible to run the cluster without LVM and DRBD storage, for
    example using a shared filesystem exported from shared storage (and
    still have live migration)

  is true.
- documentation fixes
- sync fields between ``gnt-instance list/modify/add/import``
- fix a race condition in drbd when the sync speed was set after giving
  the device a remote peer.

- Experimental readonly, REST-based remote API implementation;
  automatically started on master node, TCP port 5080, if enabled by
  ``--enable-rapi`` parameter to configure script.
- Instance allocator support. Add and import instance accept a
  ``--iallocator`` parameter, and call that instance allocator to decide
  which node to use for the instance. The iallocator document describes
  what's expected from an allocator script.
- ``gnt-cluster verify`` N+1 memory redundancy checks: Unless passed the
  ``--no-nplus1-mem`` option ``gnt-cluster verify`` now checks that if a
  node is lost there is still enough memory to fail over the instances
  that reside on it.
- ``gnt-cluster verify`` hooks: it is now possible to add post-hooks to
  ``gnt-cluster verify``, to check for site-specific compliance. All the
  hooks will run, and their output, if any, will be displayed. Any
  failing hook will make the verification return an error value.
- ``gnt-cluster verify`` now checks that its peers are reachable on the
  primary and secondary interfaces
- ``gnt-node add`` now supports the ``--readd`` option, to readd a node
  that is still declared as part of the cluster and has failed.
- ``gnt-* list`` commands now accept a new ``-o +field`` way of
  specifying output fields, that just adds the chosen fields to the
  default ones.
- ``gnt-backup`` now has a new ``remove`` command to delete an existing
  export from the filesystem.
- New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path
  have been added. Using them you can enable/disable acpi and pae
  support, and specify a path for a cd image to be exported to the
  instance. These parameters as the name suggest only work on HVM
  clusters.
- When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and
  PAE support will be set to the previously hardcoded values, but the
  (previously hardcoded) path to the CDROM ISO image will be unset and
  if required, needs to be set manually with ``gnt-instance modify``
  after the upgrade.
- The address to which an instance's VNC console is bound is now
  selectable per-instance, rather than being cluster wide. Of course
  this only applies to instances controlled via VNC, so currently just
  applies to HVM clusters.

  ``gnt-node``, ``gnt-cluster``)
- Added instance rename support
- Added multi-instance startup/shutdown
- Added cluster rename support
