This patch adds support for specifying and changing the boot device order for
HVM instances. The boot device order specification is ignored for non HVM
instances.

This patch adds support for defining the kernel/initrd at instance
creation time, using the same interface as in instance modify.

This patch adds support in ‘gnt-instance modify’ to set the kernel and
initrd paths. The user can pass either 'default' or 'none' (none is not
valid for kernel).

This patch improves the ‘gnt-cluster verify-disks’ command by adding
support for detecting broken volume groups and missing logical volume
names.

As such, we don't try anymore to activate disks for instances that are
not likely to succeed anyway, and instead report them.

Allow the MAC address of an instance to be specified optionally during

This patch adds three modes of disk replacement for drbd8:
  - replace the disk on the primary node
  - replace the disk on the secondary node
  - replace the secondary node

It also adds some debugging code to backend.py and increments the
protocol version for the recent changes of the rpc layer.

This patch series implements the reboot command for gnt-instance. It
supports three types of reboot: soft (hypervisor reboot), hard (instance
config rebuild and reboot) and full (full instance shutdown and startup
again).

This patch contains the opcode and lu part.

This patch adds a new option to the instance removal command
"--ignore-failures" that forces the removal of the instance from the
configuration even if the removal process encounters errors.

In order to be able to do this when the remote node(s) is(are) down, we
need to restrict the execution of the instance removal hook to the
master only. I think this is a reasonable trade-off (but I'm not sure).

Since modules are not directly executables, remove the shebang from
them. This helps with lintian warnings.

Also make the autogenerated _autoconf.py contain two comment lines at
the beginning, like the other modules.

This patch changes the tags opcodes to work with multiple tags at once

This patch allows 'gnt-instance add' to not start the newly-created

This patch adds a new OpCode (and corresponding LU) that implements the
cluster rename functionality.

This is done by shutting down the master role, making the needed sstore
modifications and distributing the changed files to all nodes, and then
re-enabling the master role.

The modification to the man page of gnt-cluster also moves the section
on gnt-cluster destroy in order to correct alphabetical ordering.

This patch adds support for instance rename operation at all remaining

Now that LUQueryNodes supports all the functionality of LUQueryNodeData,
let's migrate gnt-node.ShowNodeConfig to use it and remove all traces of
OpQueryNodeData and LUQueryNodeData.

LUQueryNodes it's very similar to LUQueryNodeData, but it lacks two
features:
  - instance list (it has count though), both primary and secondary
  - selective node listing

In order to support these features, we change it to return raw values
instead of stringified ones (like the recent change to LUQueryInstances)
and to support query-ing of a restricted set of nodes.

This CL also modifies the gnt-node script to conform to the new protocol
and the opcode OpQueryNodes to support the new "nodes" attribute.

This changes the raising of exceptions from:
  raise Exception, value
to
  raise Exception(value)

as the first form will be removed in python-3000 and the second form is
preferred now.

The changes also involve a few cases of changing from raising standard
exceptions and use our own ones.

The new version also fixes many pylint-generated warnings, especially in
ganeti-noded where I changed many methods to @staticmethod.

There is no functionality changed (barring any bugs).

This is only the backend part, from the command line the tags can't be
read/modified yet.
