This resolves the TODO to make the option default to True so that the source compute service will wait for the "network-vif-plugged" event, initiated by vif plugging during pre_live_migration on the destination compute servie, before initiating the guest transfer in the hypervisor. There are certain networking backends that will not send the neutron event for vif plugging alone (which is arguably a bug) but OVS and linuxbridge, probably the two most widely used in OpenStack deployments, are known to work with this config. While in here, the Timeout message is fleshed out to give more help with what the cause of the timeout could be and possible recourse. Change-Id: I8da38aec0fe4808273b8587ace3df9dbbc3ab576

|
|
The default value for the ``[compute]/live_migration_wait_for_vif_plug``
|
|
configuration option has been changed to True. As noted in the help text
|
|
for the option, some networking backends will not work with this set to
|
|
True, although OVS and linuxbridge will.
