Just to be sure, I've meant not DEVICE.realize() but each device specific one. qdev_unplug() might work for now, but I haven't checked all devices that might use interface and if it would break anything. Ideally it should be in device's unrealize() complementing realize() part. I'd wait till all buses converted to new interface before attempting to generalize current plug/unplug call pathes though. > > Paolo >
