I didn't realize it had changed from 4 -> 16 cpus so recently. I thought
we'd gone straight from 1 -> 16. With this in mind, it is worth trying

I actually have a patch mostly complete that pulls the kvm version from
qemu-kvm similar to how we grab the version from the qemu binary. I can
clean it up and post it if that seems like the way to go.
