Title:
  nova failures when vCenter has multiple datacenters

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) havana series:
  Fix Released
Status in The OpenStack VMwareAPI subTeam:
  Fix Committed
Status in “nova” package in Ubuntu:
  Confirmed

Bug description:
  The method at vmops.py _get_datacenter_ref_and_name does not calculate
  datacenter properly.

      def _get_datacenter_ref_and_name(self):
          """Get the datacenter name and the reference."""
          dc_obj = self._session._call_method(vim_util, "get_objects",
                  "Datacenter", ["name"])
          vm_util._cancel_retrieve_if_necessary(self._session, dc_obj)
          return dc_obj.objects[0].obj, dc_obj.objects[0].propSet[0].val

  This will not be correct on systems with more than one datacenter.

  vCenter error is:
  "A specified parameter was not correct. spec.location.folder"

  Work around:
  use only one datacenter, use only one cluster, turn on DRS

  Additional failures:
