this is expected, VMware API doesn't support pause operation officially.
so we can't expose this to OpenStack.

Title:
  Nova pause/unpause is not supported by vmware api

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Currently, pause and unpause functionality is not supported by the
  vmware api. Issuing the nova pause command works but does not give any
  indication of success or failure. Attempting to pause an instance via
  Horizon gives a success message but the instance stays ACTIVE.

  Relevant nova log snippet:
