Title:
  XenServer: resize confirm causes 'XenAPI failed to power the instance
  off'

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Using the latest Nova Havana code today (git commit d4c7e88c or
  later)...

  I'm now seeing resize_confirm API requests fail with Torpedo when
  running XenServer 6.1 in SmokeStack.

  The following error message is displayed in Nova's compute.log file:
