MAINFRAME on your M1
====================
We will be using the latest Ubuntu 20.10 s390x image
Download from
https://cdimage.ubuntu.com/releases/20.10/release/ubuntu-20.10-live-server-s390x.iso
Download - rename as ubuntu.iso and place in your s390x working directory
For the disk image disk.img I have used dd to create 20G dummy disk image
dd if=/dev/zero of=disk.img bs=1024 count=20M
Next we need the kernel and initrd.ubuntu from the ISO (mount it and copy it over to the
s390x working directory)
hdiutil mount ubuntu.iso
cd /Volumes/Ubuntu-Server 20

copy only kernel.ubuntu and initrd.ubuntu to your working dir
Installer
---------
qemu-system-s390x -machine s390-ccw-virtio \
-cpu max,zpci=on -serial telnet::4441,server \
-display none -m 4096 \
--cdrom ubuntu.iso \
-net nic -net user,hostfwd=tcp::2222-:22 \
-kernel kernel.ubuntu -initrd initrd.ubuntu \
-hda disk.img
Do not yet reboot the system after the installer finishes
Once installed is finished we need to copy the installed kernel.ubuntu and initrd.ubuntu from /boot to our Qemu
working directory
use scp to move these files out
cd /boot
scp kernel.ubuntu initrd.ubuntu user@10.0.2.2:/Users/user
now shut down the installer instance
Move the kernel and initrrd to your s390x working dir
Run
---
emu-system-s390x -machine s390-ccw-virtio \
-cpu max,zpci=on -serial telnet::4441,server \
-display none -m 4096 \
-net nic -net user,hostfwd=tcp::2222-:22 \
-hda disk.img
