Title:
  nova detach interface will get inconsistent if hypervisor failed to
  detach a port

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
      Currently, in compute api, detach_interface will delete neutron port
      first then calls hypervisor driver to do detach_interface on the guest.
      If the driver does detach_interface failed, in case of the driver raise
      an exception.InterfaceDetachFailed or other NovaExcptions, there is no
     handler for them. Besides this is an asyn rpc call, so nova-api will not
      notice this exception. End user will find the port has been deleted
      in neutron side, but guest still can see this port on guest, this is
      inconsistent.
