Title:
  VMware: launching instance from instance snapshot fails

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) havana series:
  New
Status in The OpenStack VMwareAPI subTeam:
  Fix Committed

Bug description:
  branch: stable/havana

  When using the nova VMwareVCDriver, instances launched from instance
  snapshots are spawning with ERROR.

  Steps to Reproduce:
  (using Horizon)
  1. Launch an instance using a vmdk image
  2. Take a snapshot of the instance
  3. Launch an instance using the snapshot

  Expected result: Instance should boot up successfully
  Actual result: Instance boots up with ERROR and following error is found in n-cpu.log:

   Traceback (most recent call last):
     File "/opt/stack/nova/nova/compute/manager.py", line 1407, in _spawn
       block_device_info)
     File "/opt/stack/nova/nova/virt/vmwareapi/driver.py", line 623, in spawn

       return self.greenlet.switch()

  The error seems to occur during the CopyVirtualDisk_Task operation.
