21.1.1
^^^^^^

Bug Fixes

* Since Libvirt v.1.12.0 and the introduction of the libvirt issue ,
  there is a fact that if we set cache mode whose write semantic is
  not O_DIRECT (i.e. "unsafe", "writeback" or "writethrough"), there
  will be a problem with the volume drivers (i.e.
  LibvirtISCSIVolumeDriver, LibvirtNFSVolumeDriver and so on), which
  designate native io explicitly.

  When the driver_cache (default is none) has been configured as
  neither "none" nor "directsync", the libvirt driver will ensure the
  driver_io to be "threads" to avoid an instance spawning failure.

   (https://bugzilla.redhat.com/show_bug.cgi?id=1086704)

* An issue that could result in instances with the "isolate" thread
  policy ("hw:cpu_thread_policy=isolate") being scheduled to hosts
  with SMT (HyperThreading) and consuming "VCPU" instead of "PCPU" has
  been resolved. See bug #1889633 for more information.

   (https://bugs.launchpad.net/nova/+bug/1889633)

* Resolve a race condition that may occur during concurrent
  "interface detach/attach", resulting in an interface accidentally
  unbind after attached. See bug 1892870 for more details.

   (https://bugs.launchpad.net/nova/+bug/1892870)

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

* Resolved an issue whereby providing an empty list for the
  "policies" field in the request body of the "POST /os-server-groups"
  API would result in a server error. This only affects the 2.1 to
  2.63 microversions, as the 2.64 microversion replaces the "policies"
  list field with a "policy" string field. See bug #1894966 for more
  information.
