Public bug reported:

Performing an instance resize which migrates the instance to another
host. When the new instance gets built up, the new VIF gets plugged,
however connectivity to the IP is delayed. arping from the neutron
router gets no response for about a minute. Same with attempts to access
via a floating IP.

If a resize is reverted and the instance goes back to the original host,
connectivity is restored almost instantly.

I've included some neutron config, let me know if more is desired.

This is on Juno.
