Damn, nope, still no joy :(. It looked like it was fixed but one of the
test was to hibernate right after the 3 kvm guests were shut down and I
guess the mem freeing pattern kinda hits it where it most hurts.
Anyways, I'm going to bed soon, will test whatever you come up with guys
tomorrow morning when I can think again.
By the way, do we want to create a new thread - the mailchain is off the
screen limits of my netbook :)
Thanks.
