Version 2.1.3

-------------

*(Unreleased)*

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

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

``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.
