Title:
  [vmware driver] VM deployment failed on non-vmware distributed virtual
  switch

Status in OpenStack Compute (Nova):
  New

Bug description:
  We are using a Cisco Nexus 1000v DVS, which is not a normal VMWare
  Distributed Virtual Switch

  And we got following error when deploying a VM:

  'VMwareDriverException:
  Required property switchUuid is missing from data object of type DistributedVirtualSwitchPortConnection

  Reason:
  The reason is that Cisco Nexus 1000v DVS' type is(Managed Object:DistributedVirtualSwitch ) , which is not a normal VMWare Distributed Virtual Switch(Managed Object:VmwareDistributedVirtualSwitch ). 
  But the vmware driver is try to fetch the uuid based on type (Managed Object:VmwareDistributedVirtualSwitch ).
  dvs_props = session._call_method(vim_util,
                                  "get_dynamic_property",
                                  props.distributedVirtualSwitch,
                                  "VmwareDistributedVirtualSwitch", "uuid")

  This code only works on normal vmware dvs, but not works on other
  types.
