We high-spiritedly announce the release of: nova 19.3.2: Cloud computing fabric controller This release is part of the stein 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. 19.3.2 ^^^^^^ 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) * Addressed an issue that prevented instances using multiqueue feature from being created successfully when their vif_type is TAP.
