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.
