    Improve DVR's resiliency during Nova VM live
    migration events.
fixes:
  - Create DVR router namespaces pro-actively on the
    destination node during live migration events. This
    helps minimize packet loss to floating IP traffic.
issues:
  - More synchronization between Nova and Neutron is needed
    to properly handle live migration failures on either
    side. For instance, if live migration is reverted or
    canceled, some dangling Neutron resources may be left
    on the destination host.
