Since Ganeti 2.6 does warn about disks with wrong iv_names, it would
be better to fix them when upgrading to 2.6.

Not sure if this is too brittle and whether we want to add more
safeguards on the contents of the config/instance/disks before
touching them.

For epydoc raise statement, it already expects an exception which will

As reported by Ben Beuchler, kvm-ifup uses bash-specific constructs and

anyway, so changing the shebang line is the easiest solution.

So while testing my previous patch I run setup-ssh manually without

This works around a problem in Paramiko, but which looks like it's a

To silence this, we do an ugly thing (since Python 2.4 doesn't support
context managers): manually reset the warnings filter, which resets
any -W command line flags (hopefully noone calls this tool manually so
often).

Introduce the rbd disk template, which handles provisioning and
management of instance disks as block devices mapped to rbd volumes
on a RADOS cluster.

The rbd template is of type DTS_EXT_MIRROR, meaning rbd-based
instances can failover or migrate to any node, without
primary-secondary limitations.

Use of this template requires the rbd kernel driver and rbd tool
on all VM-capable nodes, as well as an operational RADOS cluster,
accessible by them.
