I tried installing openstack grizzly as per the guide (

I've one controller and 2 compute nodes. I tried migrating an instance from one compute node to the other. Migragation was not successful and i ended up with "InvalidCPUInfo: Unacceptable CPU info: CPU doesn't have compatibility. " error.

I tried to upgade to nova-2013.1 by downloading nova-2013.1.tar.gz. Please help me to understand where should i install this? 1. Should I install nova-2013.1 in controller node? If yes, what is the command? 2. Do i need to install this in compute nodes? If so, then how do I install nova-compute alone.

Thanks & Regards, Catherine
