[Condor-users] Limiting jobs run on a node by VM ID?

Our compute farm has twin dual-core cpu's per machine so I have VMs named vm1@xxxxxxxxx, vm2@xxxxxxxxx, vm3@xxxxxxxxx, vm4@xxxxxxxxx, vm1@xxxxxxxxx, vm2@xxxxxxxxx etc..
Sometimes, I end up with jobs running on all 4 VMs on the same machine and, depending on what application is running, this can be a very bad thing because of the limited memory available.

Is there an easy way to specify in the classad machine attribs that I only want to run on vm1 or vm3 on a machine?
Something like this?
	Requirements = (Name == vm[1,3]@*)
