For the qtree structure we have eg for virtio block :
bus: main-system-bus
type System
dev: pcihost, id ""
bus: pci.0
type PCI
dev: virtio-blk-pci, id ""
...
And it would become :
bus: main-system-bus
type System
dev: pcihost, id ""
bus: pci.0
type PCI
dev: virtio-pci, id ""
bus: virtio.0
type VIRTIO
dev: virtio-blk, id ""
...

So it would break the alias, we must find a solution for that.
