This doesn't sound like a bug, but rather a TODO to add support for
libvirt + xen for NUMA features.

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.
