Title:
  libvirt CPU info doesn't count NUMA cells

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  The libvirt driver, when counting sockets/cores/etc., does not take
  NUMA architectures into account.  This can cause applications using
  data from the Nova API to under-report the total number of
  sockets/cores/etc. on compute nodes with more than one NUMA cell.

  Example, on a production system with 2 NUMA cells:

  $ grep ^proc /proc/cpuinfo | wc -l
    32

  $ python simple_test_script_to_ask_nova_for_cpu_topology.py
  {u'cores': u'8', u'threads': u'2', u'sockets': u'1'}

  So, if one were relying solely on Nova to obtain information about
  this system's capabilities, the results would inaccurate results.
