A new configuration option, ``[compute]/live_migration_wait_for_vif_plug``,
has been added which can be used to configure compute services to wait
for network interface plugging to complete on the destination host before
starting the guest transfer on the source host during live migration.
Note that this option is read on the destination host of a live migration.
If you set this option the same on all of your compute hosts, which you
should do if you use the same networking backend universally, you do not
have to worry about this.
This is disabled by default for backward compatibility and because the
compute service cannot reliably determine which types of virtual
interfaces (``port.binding:vif_type``) will send ``network-vif-plugged``
events without an accompanying port ``binding:host_id`` change.
Open vSwitch and linuxbridge should be OK, but OpenDaylight is at least
one known backend that will not currently work in this case, see bug
https://launchpad.net/bugs/1755890 for more details.
