20.1.0
^^^^^^

Bug Fixes

* Bug 1845986 has been fixed by adding iommu driver when the
  following metadata options are used with AMD SEV:

  * "hw_scsi_model=virtio-scsi" and either "hw_disk_bus=scsi" or
    "hw_cdrom_bus=scsi"

  * "hw_video_model=virtio"

  Also a virtio-serial controller is created when
  "hw_qemu_guest_agent=yes" option is used, together with iommu driver
  for it.

* The "DELETE /os-services/{service_id}" compute API will now return
  a "409 HTTPConflict" response when trying to delete a "nova-compute"
  service which is involved in in-progress migrations. This is because
  doing so would not only orphan the compute node resource provider in
  the placement service on which those instances have resource
  allocations but can also break the ability to confirm/revert a
  pending resize properly. See
  https://bugs.launchpad.net/nova/+bug/1852610 for more details.

* An instance can be rebuilt in-place with the original image or a
  new image. Instance resource usage cannot be altered during a
  rebuild. Previously Nova would have ignored the NUMA topology of the
  new image continuing to use the NUMA topology of the existing
  instance until a move operation was performed. As Nova did not
  explicitly guard against inadvertent changes to resource requests
  contained in a new image, it was possible to rebuild with an image
  that would violate this requirement; see bug #1763766 for details.
  This resulted in an inconsistent state as the instance that was
  running did not match the instance that was requested. Nova now
  explicitly checks if a rebuild would alter the requested NUMA
  topology of an instance and rejects the rebuild if so.

   (https://bugs.launchpad.net/nova/+bug/1763766)

* With the changes introduced to address bug #1763766, Nova now
  guards against NUMA constraint changes on rebuild. As a result the
  "NUMATopologyFilter" is no longer required to run on rebuild since
  we already know the topology will not change and therefore the
  existing resource claim is still valid. As such it is now possible
  to do an in-place rebuild of an instance with a NUMA topology even
  if the image changes provided the new image does not alter the
  topology which addresses bug #1804502.
