Title:
  Nova libvirt driver does not bind emulator threads to host CPUs

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  When pinning a guest to a specific NUMA node, the Nova libvirt driver
  does not pin the emulator threads to any host CPUs. This means that
  non-vCPU related work done by QEMU is still free to float across any
  host NUMA node.

  The expected behaviour is that the emulator threads are pinned to the
  union of host CPUs that all vCPUs are pinned to.
