Interactive live server installation on IBM z/VM (s390x)

Interactive live server installation on IBM z/VM (s390x)

[This installation without parmfile currently works on ‘groovy’ / 20.10 only, but the plan is to make it work with ‘focal’ / 20.04 soon, too.]

The following guide assumes that a z/VM guest got defined, and that is able to either reach the public cdimage.ubuntu.com server or an internal FTP or HTTP server that hosts the Ubuntu installer image.

  • Find a place to download the installer image:
user@workstation:~$ wget http://cdimage.ubuntu.com/ubuntu-server/daily-live/current/groovy-live-server-s390x.iso

user@workstation:~$
  • Now loopback 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 groovy-live-server-s390x.iso iso
user@workstation:~$ 

user@workstation:~$ ls -1 ./iso/boot/{ubuntu.exec,parmfile.ubuntu,kernel.ubuntu,initrd.ubuntu}
./iso/boot/initrd.ubuntu
./iso/boot/kernel.ubuntu
./iso/boot/parmfile.ubuntu
./iso/boot/ubuntu.exec
user@workstation:~$
  • 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 your z/VM guest that you want to use for the installation, in this example it will be guest ‘10.222.111.24’

  • And execute the ubuntu REXX script to kick-off the installation:
