Comment 1 for bug 1815989

Just want to make sure I understand this correctly after reading the bug you referenced.

1. The instance is live-migrated
2. The neutron-ovs-agent on the target node configures the port, but it's after libvirt has
   already starting sending RARPs out
3. A couple of RARPs make it out if you set a config option high enough, for example, 10

I would have figured neutron would have notified nova, and then it would have completed things, triggering the RARPs to happen after that event, but this is not my area of expertise. I'll ask someone that's more familiar with live migration operations to take a look and give their perspective.
