I think virtio devices are the only ones which actually change the pci id and have non-trivial differences. qemu-xhci can likewise be plugged into both pci and pcie slots. When plugged into a pcie slot it'll have pcie endpoint capability. That is the only difference though. Do you consider that a chameleon device? cheers, Gerd
