Public bug reported:
Observed several failure in citrix xenserver CI for this test case:
tempest.api.compute.servers.test_server_rescue
See there are timeout waiting for vif:

For rescue, it seems shouldn't wait for this event as this port should be
active at the rescuing start.
But observed:
neutron service reported the 2nd vif-plugin event:
