As far as I know, the Debian CD ISO images are not bootable on s390x (they do not contain boot information according to the El-Torrito standard). Please open a bug against Debian instead if you want to have that changed. So far, you have to boot here manually instead (see http://people.redhat.com/~thuth/blog/qemu/2017/12/19/install-fedora.html for some more information).

The Debian image is downloaded from the following link: https://cdimage.debian.org/debian-cd/current/s390x/iso-cd/debian-10.5.0-s390x-netinst.iso Using the latest QEMU version 5.1.0, the Debian image is emulated using the given command: qemu-system-s390x -boot d -m 4096 -hda debian.qcow -cdrom debian-10.5.0-s390x-netinst.iso -nographic Running the command causes the output below: LOADPARM=[ ] Using virtio-blk. Using guessed DASD geometry. Using ECKD scheme (block size 4096), CDL ! No zIPL section in IPL2 record. ! Using exactly the same qemu command above with the Alpine 3.12 image for s390x ran successfully without any errors.
