Title:
  powervm error'd local volume cleanup fails

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  During spawn, if a local volume for the backing block device fails to
  be created, the cleanup operation for the volume can fail with a
  "UnboundLocalError: local variable 'disk_name' referenced before
  assignment" error.

  The fix is to assign to disk_name earlier and check for None before
  running cleanup.
