16.1.0 ^^^^^^
Upgrade Notes *************
* On AArch64 architecture "cpu_mode" for libvirt is set to "host- passthrough" by default.
AArch64 currently lacks "host-model" support because neither libvirt nor QEMU are able to tell what the host CPU model exactly is and there is no CPU description code for ARM(64) at this point.
Warning: "host-passthrough" mode will completely break live migration, *unless* all the Compute nodes (running libvirtd) have *identical* CPUs.
* Starting in Ocata, there is a behavior change where aggregate- based overcommit ratios will no longer be honored during scheduling for the FilterScheduler. Instead, overcommit values must be set on a per-compute-node basis in the Nova configuration files.
If you have been relying on per-aggregate overcommit, during your upgrade, you must change to using per-compute-node overcommit ratios in order for your scheduling behavior to stay consistent. Otherwise, you may notice increased NoValidHost scheduling failures as the aggregate-based overcommit is no longer being considered.
You can safely remove the AggregateCoreFilter, AggregateRamFilter, and AggregateDiskFilter from your "[filter_scheduler]enabled_filters" and you do not need to replace them with any other core/ram/disk filters. The placement query in the FilterScheduler takes care of the core/ram/disk filtering, so CoreFilter, RamFilter, and DiskFilter are redundant.
Please see the mailing list thread for more information: http://lists.openstack.org/pipermail/openstack- operators/2018-January/014748.html
* This release contains a schema migration for the "nova_api" database in order to address bug 1738094:
https://bugs.launchpad.net/nova/+bug/1738094
The migration is optional and can be postponed if you have not been affected by the bug. The bug manifests itself through "Data too long for column 'spec'" database errors.
Bug Fixes *********
* The "delete_host" command has been added in "nova-manage cell_v2" to delete a host from a cell (host mappings). The "force" option has been added in "nova-manage cell_v2 delete_cell". If the "force" option is specified, a cell can be deleted even if the cell has hosts.
* If scheduling fails during rebuild the server instance will go to ERROR state and a fault will be recorded. Bug 1744325
