Open Stack

I initially did not have this setting in the nova.conf. I then read the
OpenStack docs and set it to as below and resstarted nova services and
re-created the instance but with same outcome.

libvirt_cpu_mode=host-passthrough

But I didnt have this issue with Windows Server 2012, it reported 2 virtal
CPUs correctly.

Balu
