Nested virt would really be the right solution, if we can make it work with today's hardware. It feels quite wrong that virtualization can do everything except virtualizing, it kinda breaks the abstraction.
We talked about this at the KVM Forum. Apparently Intel nested virt is *hard* .. the code is larger than the rest of KVM combined.
AMD nested virt was much easier, because AMD choose a completely different and much less hairy way to implement virt in the first place.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
