Title:
  evacuate on ceph backed volume fails

Status in OpenStack Compute (nova) icehouse series:

Bug description:
  When using nova evacuate to move an instance from one compute host to
  another, the command silently fails. The issue seems to be that the
  rebuild process builds an incorrect libvirt.xml file that no longer
  correctly references the ceph volume.

  Specifically under the <disk> section I see:

  <source protocol="rbd" name="volumes/instance-00000004_disk">

  where in the original libvirt.xml the file was:

  <source protocol="rbd" name="volumes/volume-9e1a7835-b780-495c-a88a-
  4558be784dde">
