Not sanely, no. All clusters need HA (if you don't need to coordinate
services, you don't need HA). In shared storage though, it becomes extra
critical.

As for fencing KVM; fence_xvm or fence_virsh (the former being ideal for
production, the later being easier to setup but more fragile, so only
good for testing).
