Title:
  VMware: Detaching volume fails with FileNotFoundException

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Steps to reproduce:

  a) Create nova instance vm-1 (assume that the datastore is a shared datastore 'ds-1' which is a member of datastore cluster dcls-1)
  b) Create volume vol-1 with a storage profile which maps to ds-1
  c) Attach vol-1 to vm-1
  d) Migrate vm-1's datastore to shared datastore ds-2 which is a member of the dcls-1
  (The vmdk of vol-1 *moves* to vm-1's new location after this step)
  e) Detach vol-1
