 Hi,

those debian kernel and initrd are the ones that are used for installing
Debian - they do not provide a fully installed environment with gcc etc.
So you first need to create a hard disk image (with qemu-img for
example) and then install the distro into that image.

In case you'd like to try Fedora instead, I've got some instructions for
this here:

http://people.redhat.com/~thuth/blog/qemu/2017/12/19/install-fedora.html

You just have to make sure to use the latest version 2.12 of QEMU (older
versions won't work) and then omit the "-M accel=kvm" when running
qemu-system-s390x.
