16.0.1
^^^^^^


Upgrade Notes
*************

* The "nova-conductor" service now needs access to the Placement
  service in the case of forcing a destination host during a live
  migration. Ensure the "[placement]" section of nova.conf for the
  "nova-conductor" service is filled in.


Bug Fixes
*********

* When forcing a specified destination host during live migration,
  the scheduler is bypassed but resource allocations will still be
  made in the Placement service against the forced destination host.
  If the resource allocation against the destination host fails, the
  live migration operation will fail, regardless of the "force" flag
  being specified in the API. The guest will be unchanged on the
  source host. For more details, see bug 1712008.

* When forcing a specified destination host during evacuate, the
  scheduler is bypassed but resource allocations will still be made in
  the Placement service against the forced destination host. If the
  resource allocation against the destination host fails, the evacuate
  operation will fail, regardless of the "force" flag being specified
  in the API. The guest will be unchanged on the source host. For more
  details, see bug 1713786.

   (https://bugs.launchpad.net/nova/+bug/1713786)

* It is now possible to unset the "[vnc]keymap" and "[spice]keymap"
  configuration options. These were known to cause issues for some
  users with non-US keyboards and may be deprecated in the future.
