24.1.0
^^^^^^


New Features
************

* Added a new configuration option
  "[workarounds]/enable_qemu_monitor_announce_self" that when enabled
  causes the Libvirt driver to send a announce_self QEMU monitor
  command post live-migration. Please see bug 1815989
  (https://bugs.launchpad.net/nova/+bug/1815989) for more details.
  Please note that this causes the domain to be considered tainted by
  libvirt.


Known Issues
************

* The libvirt virt driver in Nova implements power on and hard
  reboot by destroying the domain first and unpluging the vifs then
  recreating the domain and replugging the vifs. However nova does not
  wait for the network-vif-plugged event before unpause the domain.
  This can cause the domain to start running and requesting IP via
  DHCP before the networking backend has finished plugging the vifs.
  The config option
  [workarounds]wait_for_vif_plugged_event_during_hard_reboot has been
  added, defaulting to an empty list, that can be used to ensure that
  the libvirt driver waits for the network-vif-plugged event for vifs
  with specific "vnic_type" before it unpauses the domain during hard
  reboot. This should only be used if the deployment uses a networking
  backend that sends such event for the given "vif_type" at vif plug
  time. The ml2/ovs and the networking-odl Neutron backend is known to
  send plug time events for ports with "normal" "vnic_type".  For more
  information see https://bugs.launchpad.net/nova/+bug/1946729


Bug Fixes
*********

* The "POST /servers" (create server) API will now reject attempts
  to create a server with the same port specified multiple times. This
  was previously accepted by the API but the instance would fail to
  spawn and would instead transition to the error state.

* Bug #1829479 (https://bugs.launchpad.net/nova/+bug/1829479): Now
  deleting a nova-compute service removes allocations of successfully
  evacuated instances. This allows the associated resource provider to
  be deleted automatically even if the nova-compute service cannot
  recover after all instances on the node have been successfully
  evacuated.

* The bug 1952941  is fixed where a pre-Victoria server with pinned
  CPUs cannot be migrated or evacuated after the cloud is upgraded to
  Victoria or newer as the scheduling fails with "NotImplementedError:
  Cannot load 'pcpuset'" error.

   (https://bugs.launchpad.net/nova/+bug/1952941)

* Bug 1950657 (https://bugs.launchpad.net/nova/+bug/1950657), fixing
  behavior when nova-compute wouldn't retry image download when gets
  "Corrupt image download" error from glanceclient and has num_retries
  config option set.
