I did try to install with the virt-manager, it should be the same thing as
virt-install. But it turns out the bug is with the buster installer as I sent
in the other reply. So currently the following works:

$ virt-install --arch=s390x --name test --memory 1024 --disk none \
  --extra-args=console=ttyS0 \
  -l http://ftp.de.debian.org/debian/dists/stretch/main/installer-s390x/

but the same thing with buster is broken:

$ virt-install --arch=s390x --name test --memory 1024 --disk none \
  --extra-args=console=ttyS0 \
  -l http://ftp.de.debian.org/debian/dists/buster/main/installer-s390x/

And than just hangs there because of the problem with the serial port name.
