Is there any one that has solution for this problem.

Can you run "virsh capabilities" and provide the "cpu" section for both the source and dest compute nodes? Can you also provide the "cpu_mode", "cpu_model", and "cpu_model_extra_flags" options from the "libvirt" section of /etc/nova/nova.conf on both compute nodes?
