Hi Jason. My apologies for the delayed response, several work-related 
things came up recently, but they're slowing down now so I'm turning my 
attention these patches to get taken care of.

A few questions and comments below (and in other following patches):

Sure thing. And I apologize if it's obvious (I'm relatively new to virtio), but how can I expose the driver area?

I understand that virtio devices are part of the Qemu process, but I also thought that virtio drivers are in the
guest's kernel, which I don't believe I can see into from Qemu (or, at least, it's not obvious to me).
