18.2.0

Upgrade Notes
*************
* Adds a "use_cache" parameter to the virt driver "get_info" method.
Out of tree drivers should add support for this parameter.
* Live migration of instances with NUMA topologies is now disabled
by default when using the libvirt driver. This includes live
migration of instances with CPU pinning or hugepages. CPU pinning
and huge page information for such instances is not currently re-
calculated, as noted in bug #1289064. This means that if instances
were already present on the destination host, the migrated instance
could be placed on the same dedicated cores as these instances or
use hugepages allocated for another instance. Alternately, if the
host platforms were not homogeneous, the instance could be assigned
to non-existent cores or be inadvertently split across host NUMA
nodes.
The long term solution to these issues is to recalculate the XML on
the destination node. When this work is completed, the restriction
on live migration with NUMA topologies will be lifted.
For operators that are aware of the issues and are able to manually
work around them, the "[workarounds] enable_numa_live_migration"
option can be used to allow the broken behavior.
For more information, refer to bug #1289064.

migration)
Bug Fixes
*********
* "PUT /os-aggregates/{aggregate_id}" and "POST /os-
aggregates/{aggregate_id}/action" (for set_metadata action) will now
return HTTP 400 for availability zone renaming if the hosts of the
aggregate have any instances.
* Fixes a race condition that could allow a newly created Ironic
instance to be powered off after deployment, without letting the
user power it back on.
* [bug 1818295 (https://bugs.launchpad.net/nova/+bug/1818295)] Fixes
the problem with endpoint lookup in Ironic driver where only public
endpoint is possible, which breaks deployments where the controllers
have no route to the public network per security requirement. Note
that python-ironicclient fix
I610836e5038774621690aca88b2aee25670f0262 must also be present to
resolve the bug.
Other Notes
***********
* The "[workarounds]/ensure_libvirt_rbd_instance_dir_cleanup"
configuration option has been introduced. This can be used by
operators to ensure that instance directories are always removed
during cleanup within the Libvirt driver while using
"[libvirt]/images_type = rbd". This works around known issues such
as bug 1414895 when cleaning up after an evacuation and bug 1761062
when reverting from an instance resize.
Operators should be aware that this workaround only applies when
using the libvirt compute driver and rbd images_type as enabled by
the following configuration options:
* "[DEFAULT]/compute_driver = libvirt"
* "[libvirt]/images_type = rbd"
Warning: Operators will need to ensure that the instance directory
itself, specified by "[DEFAULT]/instances_path", is not shared
between computes before enabling this workaround, otherwise files
associated with running instances may be removed.
