Looks mostly good, but same issue as Alexey's patch: We are risking
qdev_get_machine() creating a Container-typed /machine node.

What about the following on top?

Alexey, if we reach agreement here, this means for you that we can just
use type_register_static() in place of qemu_machine_register() to
register your custom machine type with interface added.

Regards,
Andreas
