Title:
  Delay in network access after instance resize/migration using
  linuxbridge and vlan

Status in neutron:
  Expired

Bug description:
  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.
