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).

I think it would be nice if we can show driver area and device area as well here. 
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).
