Really depending on the structure of the management tool, they really
have no other choice. 

If you want a framework and interconnect for xen that steers clear of
blocking calls and remains (itself) transparent, you're going to have to
give a few extra pages to it so it has enough room for whatever results.

What's critical is that if you have a reasonable expectation of what's
coming there's really no reason to take much more, especially if you
know you have limited memory to begin with.

But everyone seems to have forgotten the days of 4 MB being a lot.

Anyway bordering on going off topic. I just find it ironic and humorous
that state of the art Virtualization technology is making problems that
went away magically when big ram came out re-present themselves with a
vengeance.

Best,
