I see you pass in an iso here...

...and an image here. Are these two different files?

Hm. What does the guest actually end up seeing? Does it start up at
least as far as to give you some command line? If yes, can you check
what device nodes are created, and if it does not look like you'd
expect, what virtio-ccw devices are available? (lscss or looking under
/sys/bus/ccw/drivers/virtio_ccw/)
