Do we have tests for this nested virtual hypervisor code? It would be
good to have at least a smoke test. I remember someone started adding
support to qemu-ppc-boot, probably Murilo. I suggest you take a look
around and maybe see what it takes to add it.

Just a L0 TCG with a small-ish qemu inside of it and a script to start
an L2.
