Yes, that's true.  And you're basically using virtio as the pluggable
discoverable bus, which is actually a pretty good idea.

However, what you are doing is very similar to what virtio-s390 does,
and it manages to do it just fine with the existing virtio.c
infrastructure.  The only difference is that you have a 1:1 relationship
between virtio-mmio "slots" described by the board and virtio-mmio
devices added by the user.

True, it is not pure qdev, but it is much simpler and doesn't require
convincing grumpy maintainers. :)
