I would like to get a FFE for patch https://review.openstack.org/#/c/162113/
which fixes an important bug (https://bugs.launchpad.net/nova/+bug/1414065)
in the handling of the VM state during live migration.

This patch fixes the libvirt monitoring of a live migration process, which
is often needed for the use case of applying maintenance to a hypervisor.
This patch changes the behavior of the live migration code from relying on
the success of the migrateToURI call to actively monitoring the state of
the libvirt domains to determine the status of the live migration.
