>  when in monitor and running balloon 512 from a 1024M VM, the vm dropped the size to 1020 (this value changes), then every subsequent request to balloon 512 will drop it by another 2M.  The system was running at above 60% RAM free when these requests were made.  also requesting to up the ram results in no change above 1024 (I'm guessing this is intentional, but was unable to find any documentation)
