[Users] HA wirh oVirt

Hi all, I've been asked for a HA solution and I've been testing oVirt with a NFS NAS and 2 hosts where I run 2 VMs that have a balancer at their front, each on a different host. Now I'm thinking on the possibility of a host malfunction and my question is: is there automatic migration of the VMs that are running on this host to the other host? Sorry if it is a silly question :-) Alex
