Title:
  nova instance delete issue

Status in OpenStack Compute (nova):
  Won't Fix

Bug description:
  I am seeing a behavior, while deleting nova instance it returns status as an Error and fails to delete itself. 
  So scenario, where I see this behavior is as follow:
  Create a nova VM instance.
  Create a cinder volume
  Attach this volume to nova vm instance and after that wait for volume to go to ‘In-use’ state.
  Mount the created partition to VM
  Unmount the created partition
  Detach the volume from VM instance and after that wait for volume to go to ‘Available’ state
  Delete the volume
  Delete the nova VM instance ==> It fails at this step, because status of server instance is set to Error.

  Based on logs I also see Rabbitmq error, which might explain the problem.
