Since nested kvm is relatively new and not really a full fledged feature 
yet - it should work but as you see not as stable as regular virt. I 
suggest you'll send the questions to kvm-devel, you'll get better 
feedback there, especially since the upstream kvm got new nested vmx 
patches (+CC the nested vmx developer)
