without logs of some kind i dont think anyoen will be able to hlep you with this.
you have one issue with the config which i noted inline but that should not break live migration.
but it would allow it to proceed when otherwise it would have failed.
and it woudl allow this issue to happen instead of the vm goign to error ro the migration
being aborted in pre live migrate.

you should never run with this set to false in production.
it will break nova ability to detect if netroking is configured
when booting or migrating a vm.
we honestly should have remove this when we removed nova-networks
