+ Enable this option to add support for the old s390-virtio
+ transport (i.e. virtio devices NOT based on virtio-ccw). This
+ type of virtio devices is only available on the experimental
+ kuli userspace or with old (< 2.6) qemu. If you are running
+ with a modern version of qemu (which supports virtio-ccw since
+ 1.4 and uses it by default since version 2.4), you probably won't
+ need this.
