The easiest way is probably to use an existing Linux/390 installation
on a disk attached to your system and an external monolithic kernel
containing the virtio-ccw guest support patches and the virtio drivers:

s390x-softmmu/qemu-system-s390x -machine s390-ccw -m 1024 -smp 2 -enable-kvm -kernel /path/to/your/kernel -drive file=/dev/sda,if=none,media=disk,id=drive-virtio-disk0 -device virtio-blk-ccw,devno=fe.0.0815,drive=drive-virtio-disk0,id=virtio-disk0 -append "root=/dev/vda1" -nographic
