Title:
  VMwareVCDriver: detaching volume  fails with TypeError

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  When VMwareVCDriver is being used, detaching a volume will fail. The
  following error shows up in the n-cpu log:

  ypeError: detach_volume() got an unexpected keyword argument 'encryption'

  Full log of detach operation here:
  http://paste.openstack.org/show/47179/

  The solution is to update the VMwareVCDriver method "detach_volume" to
  take an "encryption" argument.
