Right, and Jeremy was working on making the guest load-balancer aware of
that so the user-space should get fairly scheduled on service (of
course, that's assuming you run a linux guest with that logic in).
At that point, you might not need the host side balancing
any more, since the guest can move around processes
internally (if needed).
