info qom-tree shows several devices under unattached that probably should go somewhere.
The css bridge should attach to the machine, as it has a similar purpose as e.g. a pci host bridge. The autogenerated network devices should be in the same bucket as any other device; I'm just not sure about the way I went about it. The zpci devices are still problematic: I don't have a good idea where they should show up. Remaining in the unattached container are the sysbus, memory regions and cpus.
