Project Description
Overall: Existing NFS-HA Consulting solution exists (for SLES15 SP1 and SP2+) and is in production at customers. Goal is to improve this solution, enhance the documentation and make it more robust.
Goal for this Hackweek
- Rewrite and cleanup existing documentation of this solution in ASCII-DOC
- Test with SLES15 SP4 and new NFS Kernel server features introduced (unshare/hostname, NFS v4, NFSV4LEASETIME etc.)
- make sure "waitforleasetimeonstop" is NOT set to true on the exportfs primitive
- Add nfsdcltrack handling
- Use NFS exports from /etc/exports instead of ocf:heartbeat:exportfs (should make CIB simpler)

Mammuthus - The NFS-Ganesha inside Kubernetes controller by vcheng
Description
As the user-space NFS provider, the NFS-Ganesha is wieldy use with serval projects. e.g. Longhorn/Rook. We want to create the Kubernetes Controller to make configuring NFS-Ganesha easy. This controller will let users configure NFS-Ganesha through different backends like VFS/CephFS.
Goals
- Create NFS-Ganesha Package on OBS: nfs-ganesha5, nfs-ganesha6
- Create NFS-Ganesha Container Image on OBS: Image
- Create a Kubernetes controller for NFS-Ganesha and support the VFS configuration on demand. Mammuthus

Expand the pacemaker/corosync3 cluster toward 100+ nodes by zzhou
Description
Along with pacemaker3 / corosync3
stack landed openSUSE Tumbleweed. The new underline protocol kronosnet
becomes as the fundamental piece.
This exercise tries to expand the pacemaker3 cluster toward 100+ nodes and find the limitation and the best practices to do so.

New migration tool for Leap by lkocman
Update
I will call a meeting with other interested people at 11:00 CET https://meet.opensuse.org/migrationtool
Description
SLES 16 plans to have no yast tool in it. Leap 16 might keep some bits, however, we need a new tool for Leap to SLES migration, as this was previously handled by a yast2-migration-sle
Goals
A tool able to migrate Leap 16 to SLES 16, I would like to cover also other scenarios within openSUSE, as in many cases users would have to edit repository files manually.
- Leap -> Leap n+1 (minor and major version updates)
- Leap -> SLES docs
- Leap -> Tumbleweed
- Leap -> Slowroll
- Leap Micro -> Leap Micro n+1 (minor and major version updates)
- Leap Micro -> MicroOS
Hackweek 24 update
Marcela and I were working on the project from Brno coworking as well as finalizing pieces after the hackweek. We've tested several migration scenarios and it works. But it needs further polishing and testing.
Projected was renamed to opensuse-migration-tool and was submitted to devel project https://build.opensuse.org/requests/1227281
Repository
https://github.com/openSUSE/opensuse-migration-tool
Out of scope is any migration to an immutable system. I know Richard already has some tool for that.

SUSE AI Meets the Game Board by moio
Use tabletopgames.ai’s open source TAG and PyTAG frameworks to apply Statistical Forward Planning and Deep Reinforcement Learning to two board games of our own design. On an all-green, all-open source, all-AWS stack!
Results: Infrastructure Achievements
We successfully built and automated a containerized stack to support our AI experiments. This included:
- a Fully-Automated, One-Command, GPU-accelerated Kubernetes setup: we created an OpenTofu based script, tofu-tag, to deploy SUSE's RKE2 Kubernetes running on CUDA-enabled nodes in AWS, powered by openSUSE with GPU drivers and gpu-operator
- Containerization of the TAG and PyTAG frameworks: TAG (Tabletop AI Games) and PyTAG were patched for seamless deployment in containerized environments. We automated the container image creation process with GitHub Actions. Our forks (PRs upstream upcoming):
./deploy.sh
and voilà - Kubernetes running PyTAG (k9s
, above) with GPU acceleration (nvtop
, below)
Results: Game Design Insights
Our project focused on modeling and analyzing two card games of our own design within the TAG framework:
- Game Modeling: We implemented models for Dario's "Bamboo" and Silvio's "Totoro" and "R3" games, enabling AI agents to play thousands of games ...in minutes!
- AI-driven optimization: By analyzing statistical data on moves, strategies, and outcomes, we iteratively tweaked the game mechanics and rules to achieve better balance and player engagement.
- Advanced analytics: Leveraging AI agents with Monte Carlo Tree Search (MCTS) and random action selection, we compared performance metrics to identify optimal strategies and uncover opportunities for game refinement .
- more about Bamboo on Dario's site
- more about R3 on Silvio's site (italian, translation coming)
- more about Totoro on Silvio's site
A family picture of our card games in progress. From the top: Bamboo, Totoro, R3
Results: Learning, Collaboration, and Innovation
Beyond technical accomplishments, the project showcased innovative approaches to coding, learning, and teamwork:
- "Trio programming" with AI assistance: Our "trio programming" approach—two developers and GitHub Copilot—was a standout success, especially in handling slightly-repetitive but not-quite-exactly-copypaste tasks. Java as a language tends to be verbose and we found it to be fitting particularly well.
- AI tools for reporting and documentation: We extensively used AI chatbots to streamline writing and reporting. (Including writing this report! ...but this note was added manually during edit!)
- GPU compute expertise: Overcoming challenges with CUDA drivers and cloud infrastructure deepened our understanding of GPU-accelerated workloads in the open-source ecosystem.
- Game design as a learning platform: By blending AI techniques with creative game design, we learned not only about AI strategies but also about making games fun, engaging, and balanced.
Last but not least we had a lot of fun! ...and this was definitely not a chatbot generated line!
The Context: AI + Board Games
