There is a set of devices that is always part of your machine. For the PC, this is the PCI complex and SuperIO (including the keyboard controller). For pseries, we don't have that chip. We could simulate similar behavior through a usb controller and keyboard. But those are devices that not every pseries VM will want to have. So it really is libvirt's or the xml's job to add these. Even on x86 there are Atom chips out now that run without SuperIO, so we might eventually have an x86 machine type without keyboard too, who knows. Alex
