Linux usually keeps very little RAM free (it's kept as cache). So there

I'm waiting for 2.6.32 to hit Debian Sid before I start playing with ksm (I
don't think its in 2.6.31).
The problem is it should be automatic. The balloon driver itself or some
other mechanism should be capable of noticing when it can free up a bunch of
guest memory. I can't be bothered to manually sit around and monitor memory
usage on my host so I can then go into virt-manager to reduce memory to each
guest.
That should be pretty easy though it will have an effect on guest
performance.
