Thanks Sean for your response. Setting virt_type to kvm doesn’t help. n-cpu service is failing to come up.

Thanks Gorka for your response.
I have changed the version of libvirt and qemu on my host and I am able to move past the previous error mentioned in my last email.
Current versions of libvirt and qemu:
root@CSSOSBE04-B09:/etc# libvirtd --version libvirtd (libvirt) 1.3.1
root@CSSOSBE04-B09:/etc# kvm --version QEMU emulator version 2.5.0

Also, I made a change in /etc/nova/nova.conf and set virt_type=qemu. Earlier it was set to kvm.
I restarted all nova services post the changes but I can see one nova service was disabled and state was down.
Not sure if it is related or not, but I don't believe you want to change virt_type t0 "qemu". That should stay "kvm".
