  Hi,

Also I'd suggest to add a sysbus -> s390-virtio bus bridge device, so
your bus gets properly hooked up in the device tree. Have a look at
the (quite simple) "isabus-bridge" device in isa-bus.c, which is used
with 'qemu -M isapc'. You'll see the s390-virtio bus and all virtio
devices attached to it in 'info qtree' then.

Uh, ok :o. Is that really important?

Quite a few things depend on it. I think creating disks via '-device virtio-blk-s390' will not work without that ...

cheers,
  Gerd
