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
