23.1.0
^^^^^^


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

* As part of the fix for bug 1910466, code that attempted to
  optimize VM CPU thread assignment based on the host CPU topology as
  it was determined to be buggy, undocumented and rejected valid
  virtual CPU topologies while also producing different behavior when
  CPU pinning was enabled vs disabled. The optimization may be
  reintroduced in the future with a more generic implementation that
  works for both pinned and unpinned VMs.


Bug Fixes
*********

* The nova libvirt driver supports two independent features, virtual
  CPU topologies and virtual NUMA topologies. Previously, when
  "hw:cpu_max_sockets", "hw:cpu_max_cores" and "hw:cpu_max_threads"
  were specified for pinned instances ("hw:cpu_policy=dedicated")
  without explicit "hw:cpu_sockets", "hw:cpu_cores", "hw:cpu_threads"
  extra specs or their image equivalent, nova failed to generate a
  valid virtual CPU topology. This has now been fixed and it is now
  possible to use max CPU constraints with pinned instances. e.g. a
  combination of  "hw:numa_nodes=2", "hw:cpu_max_sockets=2",
  "hw:cpu_max_cores=2", "hw:cpu_max_threads=8" and
  "hw:cpu_policy=dedicated" can now generate a valid topology using a
  flavor with 8 vCPUs.

* Addressed an issue that prevented instances with 1 vcpu using
  multiqueue feature from being created successfully when their
  vif_type is TAP.

* Minimizes a race condition window when using the "ironic" virt
  driver where the data generated for the Resource Tracker may attempt
  to compare potentially stale instance information with the latest
  known baremetal node information. While this doesn't completely
  prevent nor resolve the underlying race condition identified in bug
  1841481 (https://bugs.launchpad.net/nova/+bug/1841481), this change
  allows Nova to have the latest state information, as opposed to
  state information which may be out of date due to the time which it
  may take to retrieve the status from Ironic. This issue was most
  observable on baremetal clusters with several thousand physical
  nodes.
