We are overjoyed to announce the release of: nova 24.2.0: 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. 24.2.0 ^^^^^^ Bug Fixes ********* * As a fix for bug 1942329 (https://bugs.launchpad.net/neutron/+bug/1942329) nova now updates the MAC address of the "direct-physical" ports during mova operations to reflect the MAC address of the physical device on the destination host. Those servers that were created before this fix need to be moved or the port needs to be detached and the re- attached to synchronize the MAC address. * [bug 1958636 (https://bugs.launchpad.net/nova/+bug/1958636)] Explicitly check for and enable SMM when firmware requires it. Previously we assumed libvirt would do this for us but this is not true in all cases. * Bug #1978444 (https://bugs.launchpad.net/nova/+bug/1978444): Now nova retries deleting a volume attachment in case Cinder API returns "504 Gateway Timeout". Also, "404 Not Found" is now ignored and leaves only a warning message. * Bug #1981813 (https://bugs.launchpad.net/nova/+bug/1981813): Now nova detects if the "vnic_type" of a bound port has been changed in neutron and leaves an ERROR message in the compute service log as such change on a bound port is not supported. Also the restart of the nova-compute service will not crash any more after such port change. Nova will log an ERROR and skip the initialization of the instance with such port during the startup. * During the havana cycle it was discovered that eventlet monkey patching of greendns broke ipv6. https://bugs.launchpad.net/nova/+bug/1164822 Since then nova has been disabling eventlet monkey patching of greendns. Eventlet adressed the ipv6 limitation in v0.17 with the introduction of python 3 support in 2015. Nova however continued to disable it, which can result i slow dns queries blocking the entire nova api or other binary because socket.getaddrinfo becomes a blocking call into glibc see: https://bugs.launchpad.net/nova/+bug/1964149 for more details. * If compute service is down in source node and user try to stop instance, instance gets stuck at powering-off, hence evacuation fails with msg: Cannot 'evacuate' instance <instance-id> while it is in task_state powering-off. It is now possible for evacuation to ignore the vm task state. For more details see: bug 1978983 (https://bugs.launchpad.net/nova/+bug/1978983) * When vDPA was first introduced move operations were implemented in the code but untested either in a real environment or in functional tests. Due to this gap nova elected to block move operations for instance with vDPA devices. All move operations except for live migration have now been tested and found to indeed work so the API blocks have now been removed and functional tests introduced. Other operations such as suspend and live migration require code changes to support and will be enabled as new features in the future. Other Notes *********** * A workaround has been added to the libvirt driver to catch and pass migrations that were previously failing with the error: "libvirt.libvirtError: internal error: migration was active, but no RAM info was set" See bug 1982284 for more details.
