Interactive live server installation on IBM z/VM (s390x)
Note:
This documentation has moved to a new home! Please update your bookmarks to the new URL for the up-to-date version of this page.
Doing an interactive (manual) live installation as described here - meaning without specifying a parmfile - has been supported in Ubuntu Server since LTS 20.04.5 (‘Focal’).
The following guide assumes that a z/VM guest has been defined, and that it is able to either reach the public cdimage.ubuntu.com server or an internal FTP or HTTP server that hosts an Ubuntu Server 20.04 installer image, like this 20.04 (a.k.a. Focal) daily live image
Find a place to download the installer image:
user@workstation:~$ wget

Now loop-back mount the ISO to extract four files that are needed for a z/VM guest installation:
user@workstation:~$ mkdir iso
user@workstation:~$ sudo mount -o loop ubuntu-20.04.5-live-server-s390x.iso iso
user@workstation:~$
user@workstation:~$ ls -1 ./iso/boot/{ubuntu.exec,parmfile.*,kernel.u*,initrd.u*}
./iso/boot/initrd.ubuntu
./iso/boot/kernel.ubuntu
./iso/boot/parmfile.ubuntu
./iso/boot/ubuntu.exec
Now transfer these four files to your z/VM guest (for example to its ‘A’ file mode), using either the 3270 terminal emulator or FTP.
Then log on to the z/VM guest that you want to use for the installation. In this example it will be guest ‘10.222.111.24’.
Execute the ubuntu REXX script to kick-off the installation:

In the usual case that no parmfile was configured, the installation system now offers to interactively configure the basic network:
Attempt interactive netboot from a URL?
yes no (default yes): yes
Available qeth devices:
0.0.0600 0.0.0603
zdev to activate (comma separated, optional): 0600
QETH device 0.0.0600:0.0.0601:0.0.0602 configured
Two methods available for IP configuration:
* static: for static IP configuration
* dhcp: for automatic IP configuration
static dhcp (default 'dhcp'): static
ip: 10.222.111.24
gateway (default 10.222.111.1): .
dns (default .):
vlan id (optional):
http://cdimage.ubuntu.com/ubuntu/releases/20.04.5/release/ubuntu-20.04.5-live-server-s390x.iso (default)
url: ftp://10.11.12.2:21/ubuntu-live-server-20.04.5/ubuntu-20.04.5-live-server-s390x.iso
http_proxy (optional):
Ensure that the same version of the ISO image that was used to extract the installer files – kernel and initrd – is referenced at the ‘url:’ setting. It can be at a different location, for example directly referencing the public cdimage.ubuntu.com server: http://cdimage.ubuntu.com/ubuntu/releases/20.04.5/release/ubuntu-20.04.5-live-server-s390x.iso
The boot-up of the live-server installation now completes:

The next step is to remotely connect to the install system and to proceed with the Subiquity installer.
Notice that at the end of the installer boot-up process, all necessary data is provided to proceed with running the installer in a remote SSH shell. The command to execute locally is:
user@workstation:~$ ssh installer@10.222.111.24
A temporary random password for the installation was created and shared as well, which should be used without the leading and trailing double quotes:
"KRuXtz5dURAyPkcjcUvA"
user@workstation:~$ ssh installer@10.222.111.24
The authenticity of host '10.222.111.24 (10.222.111.24)' can't be established.
ECDSA key fingerprint is
SHA256:xd1xnkBpn49DUbuP8uWro2mu1GM4MtnqR2WEWg1fS3o.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '10.222.111.24' (ECDSA) to the list of known hosts.
installer@10.222.111.24's password: KRuXtz5dURAyPkcjcUvA
