This configuration parameter "live_migration_wait_for_vif_plug" belongs to Nova. If you check the documentation, that parameter will tell Nova if it needs to wait (and how long) or not for the "vif-plugged-event", sent by Neutron.
When using ML2/OVS, if the port admin status is set to down, the agent reports it as DOWN and the Neutron server doesn´t send the expected "vif-plugged-event".
This is not a Neutron bug but something that should be documented in the Nova documentation.
