We are satisfied to announce the release of: nova 16.0.1: Cloud computing fabric controller This release is part of the pike stable release series. Download the package from: https://tarballs.openstack.org/nova/ For more details, please see below. 16.0.1 ^^^^^^ Upgrade Notes ************* * The "nova-conductor" service now needs access to the Placement service in the case of forcing a destination host during a live migration. Ensure the "[placement]" section of nova.conf for the "nova-conductor" service is filled in. Bug Fixes ********* * When forcing a specified destination host during live migration, the scheduler is bypassed but resource allocations will still be made in the Placement service against the forced destination host. If the resource allocation against the destination host fails, the live migration operation will fail, regardless of the "force" flag being specified in the API. The guest will be unchanged on the source host. For more details, see bug 1712008. (https://bugs.launchpad.net/nova/+bug/1712008) * When forcing a specified destination host during evacuate, the scheduler is bypassed but resource allocations will still be made in the Placement service against the forced destination host. If the resource allocation against the destination host fails, the evacuate operation will fail, regardless of the "force" flag being specified in the API. The guest will be unchanged on the source host. For more details, see bug 1713786. (https://bugs.launchpad.net/nova/+bug/1713786) * It is now possible to unset the "[vnc]keymap" and "[spice]keymap" configuration options. These were known to cause issues for some users with non-US keyboards and may be deprecated in the future.
