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 compatibilty 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.
