The only answer I have got from Openstack forum says:
"It simply means you are using wrong package and it is not supported for your architecture. Kindly see the official Centos site and try to understand if they have package available for your architecture.."
But I am not sure what it means. Do I need to get another libvirt package for CentOS that support my architecture? Is that what he meant?

This was fixed by stopping libvirt, removing all files on /var/cache/libvirt/qemu/capabilities/ and starting it again.

adrianlztSetting libvirt_cpu_mode=host-passthrough in nova.conf might solve this problem.
