This is a little wierd since it's specific to the balloon driver.  The 
virtio design is to make transport and device orthogonal so we could 
mix'n'match any driver with any transport, but this will only work with 
the balloon driver.  It's also 640 lines while the original balloon 
driver is ~300.  Some of that is because you're emulating a queue that 
doesn't really exist, IIUC.

So while I'd love to see other hypervisors adopt virtio, I think in this 
case it makes more sense to have your own balloon driver.
