If in the future we want to keep only the multiprocess case then QEMU
would be able to launch subprocesses itself.  In this case you'd keep
the old command line working but QEMU would set up the bus and the
services that work together on it (for example the basic QOM operations
such as unparent and property get/set could be mapped to a DBus
interface, and QOM classes and interfaces could also become DBus
interfaces).  The broker itself could be a separate subprocess.
