Title:
  instances always packed to NUMA node 0

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description
  ===========
  Instances are packed into node0, always. NUMA placement criteria is undefined 
when not using CPU pinning and hw:numa_nodes=1.


  Steps to reproduce
  ==================
  Create a flavor w/ hw:numa_nodes=1 (hw:cpu_policy unset)

  Spawn multiple instances

  Check nodeset in the instance XML


  Expected result
  ===============

  Use all NUMA nodes by applying some NUMA placement criteria: Spread,
  pack or random


  Actual result
  =============
  Only node 0 is used. All others are unused.


  Environment
  ===========

  Ubuntu Xenial 16.10, OpenStack Mitaka release, Libvirt 1.3.1

  Note: This issue has been found / tested on Ubuntu KVM on Power
  (ppc64le arch), however, it affects all architectures.
