I have notice in testing that if the ISO domain goes down, it does affect the vm's. The same server also has the sdm export domain on it, which I think houses most of the hard disks. Once the host came back up, everything resumed normal operations.

As far as I know, oVirt is making I/O checks frequently , so even the hard mount option won't help. Is your NFS clusterized ? If not ,you may consider clusterizing it. Actually, did your VMs got paused or completely crashed ?
