I still think that will not work for all devices.

Network cards can be identified by mac property.  Ok.

Disks can be identified by a (planned) drive property (which links to 
the host config).  By looking at the bus you can figure this is ide, 
scsi, virtio or usb-storage disk.  Fine.

Serial ports, parallel ports and virtio console need a link to a 
CharDriver which can be used to identify this group.  But not to keep 
apart serial / parallel devices.

How do you identify vga cards?
How do you identify sound cards?
How do you identify storage (scsi/ide) controllers?
How do you identify watchdog devices?
