There's probably 100 ways to skin this cat. The way we've done these 
sorts of setups in v1.2/1.3 are...

* A host definition for each physical cluster node (eg ahost01a, 
ahost01b...)
* Add the usual suspects for service checks to each physical (eg local 
disk, cpu, memory, swap...).
* A host definition for the virtual node(s) in the cluster (eg 
ahost01-print, ahost01-file...).
* Add the clustered service checks to the virtuals, including a 
check_cluster one as well (eg only the disks/Windows service checks that 
relate to that clustered service).

This would only work if you have a separate service IP for each of the 
virtuals.

Cheers.
