ZSystems

Welcome to the ZSystems edit

openSUSE for IBM Z and LinuxONE is on its way!

Due to the demand for an open z Systems distribution, we started to build the architecture s390x on the Open Build Service. Find the development project page at openSUSE:Factory:zSystems. If you want to contribute, it is recommended to submit patches via openSUSE:Factory. They will be transferred to the zSystems port after the approval.

Please join the opensuse-zsystems mailing list for questions or help.

Topics edit

openSUSE Tumbleweed

The first installable test version of openSUSE Tumbleweed is available. To install, use the repositories available at http://download.opensuse.org/ports/zsystems/tumbleweed/repo/oss/ or download the ISO image from http://download.opensuse.org/ports/zsystems/tumbleweed/iso/. Note that this project is a port to Tumbleweed, and not a fully supported architecture.

For more information about Tumbleweed, see Tumbleweed.

Virtualization

Minimal VM images have been introduced with openSUSE Leap 16 and OpenShift AI/Virtualization for s390x. They are also provided via the Lima Project and our own repositories:

Leap 16:

• https://download.opensuse.org/distribution/leap/16.0/appliances/

Tumbleweed:

• https://download.opensuse.org/ports/zsystems/tumbleweed/appliances/

Info: PCI is disabled in the Leap kernel for s390x. boo#1252096 has identified that "-pci" as a qemu option can not be used. Use "-device virtio-scsi,id=scsi0" instead.

Container Images (Docker Hub)

There are builds of Docker images based on openSUSE Tumbleweed available:

• https://registry.hub.docker.com/r/opensuse/tumbleweed

openSUSE Leap

The current installable version of our stable release openSUSE Leap is 15.5. You can download the iso image for s390x from https://download.opensuse.org/distribution/leap/15.5/iso/ . Installation media are available for default installations as well as for network installations.

Testing

Automatic tests are performed by openQA and are publicly available: https://openqa.opensuse.org/group_overview/34

The more adventerous people might want to check out the untested images. The latest image is always found at:

• https://build.opensuse.org/package/binaries/openSUSE:Factory:zSystems/000product:openSUSE-dvd5-dvd-s390x/images

You can report bugs for Tumbleweed and Leap in our openSUSE Bugzilla.

Participate

• Find the current status of the project at the starting page at openSUSE:Factory:zSystems.
• Tutorial how get get involved can be found at openSUSE:Build_Service_Tutorial.
• To run manual builds, get yourself a community cloud instance from Marist college at LinuxONE Community Cloud. Find a short step-by-step guide at ZSystems/Community cloud access. Upgrade SLES to openSUSE.
• openSUSE:Factory:zSystems is based on openSUSE:Factory. All submissions should thus go to openSUSE:Factory or the respective development projects.

Things to do edit

• Fix ZSystems/Failing_Packages (including becoming a watcher of the openSUSE:Factory:zSystems project (add it to your watch list from within the openSUSE build service webUI)
• Create Container Images for s390x
• Good First Issues
• openSUSE Bugreports for s390x
• Get awareness of openSUSE community
• Find partners that help with building openSUSE

Trainings/Meetings edit

We provide bi-weekly meetings with trainings for knowledge sharing in our team. That includes mainframe topics, packaging, OBS and containerization.

• bi-weekly Tuesday: 19:00 (German time)/ 10:00 (Pacific time)/ 18:00 (Nigeria) / 14:00 (Brazil)
