true.

false.  if you wanted, you could have every VM advertise itself with
the full RAM on the machine by defining "MEMORY" in your config file
to the total RAM on the machine * the number of VMs you'll advertise.  

however, everything else i said was true.  ;) so, there's currently no
way to allow condor to notice once a job is matched on the machine and
have the other VMs automatically advertise less available RAM.  

this will change once we finish converting all of Condor to new
classads.
