Open Stack

Hi Diego ,

Thanks for sharing steps for VM migration from customer end to your cloud.
Well! i am not going to propose new idea for VM migration. I am using VM
migration  for POC of my research idea.

I have few question for you!


1. Can we use suspend/pause feature instead of snapshot for saving VM
states. ?
2. How you are managing VM metadata (such as instance detail from
nova,cinder database)



Is it possible for you to share script? I need this VM migration feature in
Openstack for POC only.
Thanks again for your reply.


Regards
Naveed
