Take a look at the information needed for your fence agent: # pcs resource describe fence_virt

Without seeing system logs, I'd guess you need to add the port= parameter to your STONITH device configurations. Those should be the machine names from the hypervisor's perspective.

If that's not the case: # grep fence_virt /var/log/messages should get you pointed in the right direction.

You'll also want to add location constraints to keep those devices running on the correct node; the device to fence nub1 should never run on nub1, and the device to fence nub2 should never run on nub2.
