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

* Live migration of instances with NUMA topologies is now disabled
  by default when using the libvirt driver. This includes live
  migration of instances with CPU pinning or hugepages. CPU pinning
  and huge page information for such instances is not currently re-
  calculated, as noted in bug #1289064. This means that if instances
  were already present on the destination host, the migrated instance
  could be placed on the same dedicated cores as these instances or
  use hugepages allocated for another instance. Alternately, if the
  host platforms were not homogeneous, the instance could be assigned
  to non-existent cores or be inadvertently split across host NUMA
  nodes.

  The long term solution to these issues is to recalculate the XML on
  the destination node. When this work is completed, the restriction
  on live migration with NUMA topologies will be lifted.

  For operators that are aware of the issues and are able to manually
  work around them, the "[workarounds] enable_numa_live_migration"
  option can be used to allow the broken behavior.

  For more information, refer to bug #1289064.

Bug Fixes
*********

* The os-volume_attachments update API, commonly referred to as the
  swap volume API will now return a "400" (BadRequest) error when
  attempting to swap from a multi attached volume with more than one
  active read/write attachment resolving bug #1775418.
