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.
