I don't think anybody is currently working on that,
though it is an obvious gap to fill in at some point.

I would caution against testing hypervisors on QEMU
rather than against hardware or the Fast Model,
except for anything other than basic smoke tests,
though -- there are a lot of complications and corner
cases in the architecture here and I expect we will
spend some time flushing out bugs as OSes expose
them.
