Seriously. It's almost as if nobody here is actually reading anything of 
what I've written!

EVERYTHING fits in RAM. The non-guest processes total perhaps a GB in 
total. The guest processes total maybe 200 GB in total. The server has 
more RAM than all of that.

I know this works because I have literally done it on many, many 
hypervisors for over a decade.
