Title:
  Nova CPU details  socket not correct

Status in OpenStack Compute (Nova):
  New

Bug description:
  we are using Mirantis 6.0 
  we are trying to find a physical CPU information  from Nova compute host . e are using nova hypervisor-show command.

  when i tried running the nova hypervisor-show <compute_node>

  its show me correct info cpu_arch , cpu_info_features and cores ...
  but its show its only one sockets where as we are using 2 CPU .( see
  details from compute node below)

  
   

  
  we are trying to find physical CPU details from Nova-compute host blade , 

  Here is what nova shows

  root@node-9:~# nova hypervisor-show node-12
