Title:
  Instance vm_state remains 'migrating' if source compute node goes down
  during migration

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Scenario: During live migration of an instance, if the source Compute
  node goes down, the instance vm_state remains set to 'migrating'.

  Expected Behavior: The instance state must be updated to vm_state to
  'error'.

  Actual Behavior: Instance remains in following state
  vm_state=migrating, task_state=NULL, power_state=1

  Such instances should be monitored and the vm_state must be updated to
  'error'. Because until the source compute server comes up, no actions
  can be performed on the instance.
