Notice that the constraint isn't all that crazy in the command above.  
What is crazy is the -f (-format) option to print out the state of the 
VM.  It prints the state of the VM in a way that takes into account the 
state of the suspension VM.

When condor doesn't have any other job to run, it can be configured to 
run "backfill" processes.  (This was a new feature added in the last 
year or so.)  This is being used on glow.  The state of the condor VM 
will show up as "Backfill".
