We are overjoyed to announce the release of: nova 21.1.1: Cloud computing fabric controller This release is part of the ussuri 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. 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.
