Open Stack

Hi Doude,

Right now, I have no words regarding to which version you are using. I 
just want to show quick solution..
I was thinking, as you say, libvirt.template is different.
I recommend you just replace libvirt.template at src and dst physical 
server, and restart both nova-compute,  and launch new instance, then 
try again.
