Title:
[libvirt] virt_type=xen doesn't support NUMA related features
Status in OpenStack Compute (nova):
Opinion
Bug description:
With the change of https://review.openstack.org/#/c/465160,
NUMA related features like CPU pinning, hugepages, and realtime are now
explicitly disabled when using libvirt driver with `virt_type=xen`,
and compute hosts with libvirt/xen driver are filtered out with
NUMATopologyFilter.
We should test and make clear which of the NUMA related features can be
supported
by libvirt/xen driver and enable them with documents.
Note: Remenber to update at least these documents when they are enabled.
