QEMU for S390 has presently no USB controllers nor a PCI bus. Both are created by the default in the libvirt domain definition. Although this can be suppressed by explicitly specifying an USB controller with model='none', it's a real bad default. With Jan's recent patch we can reliably suppress the USB controller (including it's bogus PCI address) if the source XML has no usb controller element. Explicitly set addresses are still honored.
