22.4.0
^^^^^^

Known Issues

* The libvirt virt driver in Nova implements power on and hard
  reboot by destroying the domain first and unpluging the vifs then
  recreating the domain and replugging the vifs. However nova does not
  wait for the network-vif-plugged event before unpause the domain.
  This can cause the domain to start running and requesting IP via
  DHCP before the networking backend has finished plugging the vifs.
  The config option
  [workarounds]wait_for_vif_plugged_event_during_hard_reboot has been
  added, defaulting to an empty list, that can be used to ensure that
  the libvirt driver waits for the network-vif-plugged event for vifs
  with specific "vnic_type" before it unpauses the domain during hard
  reboot. This should only be used if the deployment uses a networking
  backend that sends such event for the given "vif_type" at vif plug
  time. The ml2/ovs and the networking-odl Neutron backend is known to
  send plug time events for ports with "normal" "vnic_type".  For more
  information see https://bugs.launchpad.net/nova/+bug/1946729
