that sounds good! Btw, networking and SMP should work fine with NOVA in
general. Of course, VirtualBox is still in flux. For example, there is
no support for using the network from a guest OS yet. But that will
follow for sure.

This is much more involved. To me, it ultimately does not look like a
SMP system but a NUMA system. An OS that would span all the VMMs would
need to account for this structure to get good performance. By modeling
a system like this, you will certainly need to implement a distributed
shared memory mechanism. NOVA, with handling page faults at the user
level, is generally suitable for that. But the topic is still extremely
