Question on paging though. You're supposed to have, like twice the amount of
allocated guest memory in paging space. So assuming I do, will I ever fill
it up?
IE, if I total up the memory from user direct, double it, and have that much
paging
space (though I have tripled it to be safe), can I ever fill it up?

Thanks,
Mary Anne
