Im running KVM on a Ubunutu 14.05 server. The server has 2 1.2TB drives which will each have 1 VM (elastic search nodes). I did a dd to clone the main OS and can boot from either disk without issue.
In the event that the primary OS drive goes down and I boot from the back up, will I have to do anything special to have the back up OS read the VMs? From my testing it seemed like it didn't.
