> What do the stats for / from within kvm look like?

Interesting - what they look like is inactive_anon is always zero.  Details below - I took the host numbers at the same time and they are similar to what I reported before.

					Jeff

The fields are inactive_anon, active_anon, inactive_file, active_file - shortly after the data started being collected, I started firefox and an editor thingy.  The data continues as far into the shutdown as it could.
