Title:
  XenAPI: wait_for_vhd_coalesce times out when garbage collector still
  running

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  In some runs, particular stress tests, the GC may run for more than 25
  seconds.  The current timeout is after 5*5 seconds and so this needs
  to be increased.
