We are glad to announce the release of: nova 24.1.1: Cloud computing fabric controller This release is part of the xena stable release series. The source is available from: https://opendev.org/openstack/nova Download the package from: https://tarballs.openstack.org/nova/ Please report issues through: https://bugs.launchpad.net/nova/+bugs For more details, please see below. 24.1.1 ^^^^^^ Bug Fixes * Instances with hardware offloaded ovs ports no longer lose connectivity after failed live migrations. The driver.rollback_live_migration_at_source function is no longer called during during pre_live_migration rollback which previously resulted in connectivity loss following a failed live migration. See Bug 1944619 for more details. (https://bugs.launchpad.net/nova/+bug/1944619) * Amended the guest resume operation to support mediated devices, as libvirt's minimum required version (v6.0.0) supports the hot- plug/unplug of mediated devices, which was addressed in v4.3.0. * Fixed bug 1960230 (https://bugs.launchpad.net/nova/+bug/1960230) that prevented resize of instances that had previously failed and not been cleaned up. * The bug 1960401 is fixed which can cause invalid *BlockDeviceMappings* to accumulate in the database. This prevented the respective volumes from being attached again to the instance. (https://bugs.launchpad.net/nova/+bug/1960401) * Fixes slow compute restart when using the "nova.virt.ironic" compute driver where the driver was previously attempting to attach VIFS on start-up via the "plug_vifs" driver method. This method has grown otherwise unused since the introduction of the "attach_interface" method of attaching VIFs. As Ironic manages the attachment of VIFs to baremetal nodes in order to align with the security requirements of a physical baremetal node's lifecycle. The ironic driver now ignores calls to the "plug_vifs" method.
