Hi Chris,

I have also faced the same issue with the trixie ISO.
https://ftp.debian.org/debian/dists/stable/main/installer-s390x/current/images/generic/
I downloaded the initrd and kernel files from this link and used (as I remember)
the following flags along with qemu:

qemu-system-s390x \
  -M s390-ccw-virtio -m 4G \
  -enable-kvm \
  -cpu host \
  -smp 4 \
  -nographic \
  -kernel debian_files/kernel.debian \
  -initrd debian_files/initrd.debian \
  -append "modules=virtio_net" \
  -drive file=debian_s390x.qcow2,if=none,id=drive0,format=qcow2 \
  -device virtio-blk-ccw,drive=drive0,bootindex=1 \
  -netdev user,id=net0 \
  -device virtio-net-ccw,netdev=net0 \
  -object rng-random,filename=/dev/urandom,id=rng0 \
  -device virtio-rng-ccw,rng=rng0

I did not try out the same with virt-manager.
Also, I don't know what exactly is the problem with the ISO
and also don't know on how to fix it.

Thanks,
Pranav
