That is exactly how I would do it, yes -- in fact, just this morning I
sent this very solution to someone privately asking the same question.

I would like to know how to ensure jobs are scheduled onto free nodes,
that is 1 per node, rather then 1 per processor on a dual processor
node. Also, I would like to know how to configure the same situation
if the nodes are hyperthreaded and showing 4 processors.
What we have come up with here is, In order to send jobs first to
free nodes it can be used something like the condor_schedd
configuration variable APPEND_RANK:
(to append an expression at the rank coming from the jobs)
Something to consider the VM id is:
APPEND_RANK = (0 - VirtualMachineId)
Is this the proper way to go about this?
