Linux on IBM Z and IBM LinuxONE use the s390x hardware architecture to run various Linux distributions, including SUSE Linux Enterprise Server (SLES), Red Hat Enterprise Linux (RHEL), and Ubuntu. Tens of thousands of software packages are tested and distributed through these projects, and various community distributions.
But for some applications, a team at IBM pays special attention to make sure they compile and run as expected (or better!). This work is often done as a collaboration between the open source projects themselves and the team at IBM. This effort is an on-going collaboration with every release of the software needing to be validated.
Welcome to our monthly report!
For the month of March 2025, the team worked to also validate recent versions of the following:
- Ansible
- Apache ActiveMQ
- Apache Camel
- Apache Cassandra
- Apache CouchDB
- Apache Solr
- Apache Tomcat
- Bazel
- cAdvisor
- Consul
- Couchbase
- Erlang
- etcd
- Falco
- HAProxy
- Htop
- Jenkins
- Kind
- Logstash
- MariaDB connector ODBC
- MongoDB Driver - C
- MongoDB Driver - PHP
- NGINX
- OPA
- PM2
- R
- RabbitMQ
- Spire
- Terraform
- Zabbix Agent
- Zabbix Server
The full list of validated software to date is available here: https://www.ibm.com/community/z/open-source-software/
We were also happy to see s390x support added for linux-syscall, and subsequent binaries produced on the crates.io registry. Additionally, the segyio project (a C library for easy interaction with SEG-Y and Seismic Unix formatted seismic data, with language bindings for Python and Matlab) added s390x to ci.

Are you a developer for an open source project interested in seeing your application made available to users on Linux on IBM Z and IBM LinuxONE? Your first stop should be the IBM LinuxONE Community Cloud where you can sign up for a free virtual machine for 120 days where you can see how your application runs, and discover for yourself what you may need to change to get it to run well on Linux on IBM Z and IBM LinuxONE.
If you wish to have permanent virtual machines for development, testing, or to add to your CI system, you can fill out this form to apply for resources for your project.
