Although you mention in all above devices the type of bus in the code that differentiation does not really exist. It originates from the way the capability QEMU_CAPS_DEVICE_VIRTIO_REVISION is sensed and set, e.g. virQEMUCapsObjectPropsVirtioBalloon[] is also used for virtio-balloon-ccw devices. I would suggest to create a QEMU_CAPS_DEVICE_VIRTIO_PCI_REVISION and sense the capability for pci only and also generate the command line parameters for pci only since the virtio pci revision handling does not work at all for virtio ccw.
