BTW, another advantage of qemu is that you could write a model of your
possibly non-standard I/O hardware and even run your drivers in qemu
against this model. That works both with and without kvm support.

And as we are at it: qemu (in emulation mode) is also capable of
providing a host for ARM, PPC, MIPS, etc. targets. An example: I'm able
to run the unmodified Linux firmware of my ARM-based webradio inside
qemu, and it works as in real life (it just boots faster in qemu than on
real silicon ;)).
