Hi Mirek, thanks a lot for that detailed explanation mentioning both the tools and links. That's definitely useful - will include it in our ZSystem wiki as soon as time permits.

More Recent Version For s390-tools (2.31 => 2.34) on Tumbleweed
by Holger Rauch 26 Aug '24

26 Aug '24

Hello to all ZSystems list members, I've got a few questions concerning the s390-tools package: - According to https://github.com/ibm-s390-linux/s390-tools/releases the most current release would be 2.34, which is also intended specifically for 6.10 kernels. As 6.10 kernels are the current ones on Tumbleweed for s390x, an upgrade seems reasonable. - Are there any technical reasons why the package release hasn't been upgraded since February this year, despite the fact that newer kernels for s390x have been made available? - As this package is intended for the base system of s390x only, I wonder why this package is built in openSUSE:Factory instead of the ZSystems-specific factory openSUSE:Factory:zSystems ? - What would be possible reasons for NOT upgrading this package to its current release 2.34 and stay with the current one 2.31 instead? Thanks for any additional info/clarifications. Kind regards, Holger

Then I gave the trainings for s390-tools based on an old feature set. I will add these links to our openSUSE zSystems wiki for future trainings and if anybody requires that. > > [1] https://www.ibm.com/docs/en/linuxonibm/pdf/lx24se04.pdf > [2] https://www.ibm.com/docs/en/linux-on-systems?topic=execution-attesting#t_at… > [3] https://video.ibm.com/recorded/132127046 Best regards, Sarah > > > Mirek Franc >

Hello together, IBM has published a Redbook about AI for Linux on Z: https://ibm.github.io/ai-on-z-101/blog/archive/2024/ From my perspective, we can use it as a foundation to understand their strategies with AI better. Then we can analyze also their installation methods for different packages. Best regards, Sarah

Docker Engine on SLES (s390x)
by Raphael Groner 04 Aug '24

04 Aug '24

Hi, can someone please explain those two requirements mentioned explicitly in official docker documentation? What restrictions do they mean? Compare to docker page in OpenSUSE Wiki without those hints (lost a link for latter). " 1. Other architectures, including x86_64, aren't supported for SLES. 2. You must add the OpenSUSE SELinux repository. This repository is not added by default. " https://docs.docker.com/engine/install/sles/ Further, there's explicitly RHEL9 for s390x only. What gets me confused because docker is technically available for all architectures. "The installation instructions on that page refer to packages for RHEL on the s390x architecture (IBM Z). Other architectures, including x86_64, aren't yet supported for RHEL." https://docs.docker.com/engine/install/rhel/ All in all, maybe it is possible to run Fedora (Rawhide or stable) inside a RHEL or SLES/OpenSUSE with docker environment? <rant> Run docker inside yet another docker? </rant> Regards Raphael
