Nothing easy that I can see. Each device needs 2 of these.  Avi, Gleb,
any objections to increasing the limit to say 16?  That would give us
5 more devices to the limit of 6 per guest.


Increase it to 200, then.

OK. I think we'll also need a smarter allocator
than bus->dev_count++ than we now have. Right?

No, why?
We'll run into problems if devices are created/removed in random order,
won't we?

unregister_dev() takes care of it.

Eventually we'll want faster scanning than the linear search we employ
now, though.
Yes I suspect with 200 entries we will :). Let's just make it 16 for
now?

Let's make it 200 and fix the performance problems later. Making it 16 is just asking for trouble.
