Past resistance to this has been grounded in not wanting to expose the exact arrangement of the qtree as a user-facing thing that needs to be maintained for back-compat reasons. Eg in your example the i440fx-pcihost sits directly on the 'system bus', but this is an odd artefact of the old qbus/qdev system and doesn't really reflect the way the system is built up in terms of QOM components; we might one day want to restructure things there, which would AIUI break a command line like > To uniquely identify this we can have a string: > > > /dev[1]/bus[pci/0]/dev[id=balloon0]/bus[virtio-bus]/dev[0]/deflate-on-oom=true thanks -- PMM
