qemu has the ability to emulate having real hardware ;-)  Here's
the patch that sets that up in ktest:

I feel like we need to merge ktest and oscheck.  oscheck assumes that you
know how to set up qemu, and ktest takes care of setting up qemu for you.
I don't think it's possible to set up DAX testing in the current oscheck
framework ... but I think it might be possible to turn oscheck into a
set of ktest tests.
