I actually think a hidden device is a useful concept to model. E.g. you can have a powered off slot and a PCI device in such a slot isn't visible but isn't gone either. Right now we force-eject such devices. But it sounds reasonable that e.g. a bunch of guests cooperate and share an assigned device and then whoever wants to use it, powers it up. These patches do not implement this of course but it's a step in that direction. -- MST
