Why couldn't this script just be a wrapper around qemu?

I get the kvm developers developing features that isn't ideal, but for
the quick boot a kernel tests, I don't see why a well maintained qemu
wrapper isn't superior. I hate constructing qemu command lines, but a
script in the kernel repo seems like a good idea.
