Thanks @Jie Song for the clarification. It seems as per the document openstack provides NUMA cpu aware configuration for the guest VM. However, my requirement seems practical as it may required to pin guest cpus to particular numa node of the host. is it possible to do that in openstack as nova has access and awareness to the host resources. I know, virsh vcpupin is possible in the runtime but changing the guest vm xml may also possible ( feasible ) using instance flavor.
