Yes, actually the IH is able to route any IV to any ring based on the
client ID, e.g. who is sending the IV.
So I'm currently looking into routing the VM faults to ring 2 as well.
That should allow us to better handle them and avoid overwhelming the
CPU with an interrupt storm in case of page faults.

Christian.
