I once had a bad dream.
I started good, a sunny day. I had just fixed an issue and push it to my fork, in order to create a Pull Request. I was happy. It felt awesome to have found a fix so elegant. Two lines of code.
But then, something happened. A cloud appear in the sky and partially hide the sun. github triggered the end to end test suite. You could see the waiting icon, you could almost hear the engines starting, ... a lightning and a thunder appeared in the sky, the sky turned dark and the e2e test started in our private jenkins server.
1 hour passed by... 2 hours .... the e2e tests still running ... 4 hours, not even 50%. Finally, I had to go, get some dinner, get some rest, so I decided to look at it the next day.
Sleep was not good. Dreaming the tests would fail and the deadline be missed .... I couldn't sleep no more so I wake up early in the morning, before sunrise. The computer still opened was lightning up the room. Out, the storm turned out to be a heavy rain. And the tests did not passed! 4 hours and half after starting them, so half an hour after leaving for dinner, and there was a fail test.
Finding out what went wrong took 2 hours...it was not even related to the code, but an infrastructure issue. A timeout when connecting to a mirror which was being restarted when the tests run. Apparently we hit a maintenance window.
Damn! So let's just "restart" the tests. This time, I decided to put an alarm 4 hours after and switch to another task, just to avoid the anxiety of the previous evening looking at the results. 4 hours passed by, and the tests are good. It is not raining anymore, a git of sun is filtering throw the window, hope is in the air. 4 more hours, and the tests still have not failed. Going to dinner and bed again and putting the alarm early in the morning. First thing in the morning I looked at the tests ... running again, feels good. All tests have passed and there is only one final "cleanup" state. Shower, breakfeast, sun is shining again!
Finally, all is green, so let's go and push the merge button ... oh oh ... clouds hide the sun again ... where is the merge button?? no way, there is a conflict with the code in master and I can't merge!!! I can't merge!!! shocked, I looked into the history ... John merged a PR overnight that was touching the same file ... hopeless I start crying on my desk...
Scared?
This is not so different on what could happen if we were running the whole e2e test suite in the SUSE Manager (uyuni) Pull Requests. However, not running any e2e tests has also a bad consequence. We find the issues after code has been merged in master, and then we spend days looking at what could have caused this, reverting commits, and starting again.
However, if we could run a subset of the e2e tests, we could shorten the time it takes and so run them at the PR level, so no broken code could get merged.
The thing is , how do we select which tests to run?
This project is about using Machine Learning to do predictive test selection, thus selecting which tests to run based on the history of previous test runs.

This could have some wider potential - clever picking of tests to shorten the time yet maximize the findings (and learning that in time based on test execution history to predict). I can see how that saves tons of money in cases where test on a real industrial machines need to be executed (e.g. cost of running engine on a test bed is 5-10k$ per day so there is huge difference if you need to run for 1 or 3 days)

Kubernetes-Based ML Lifecycle Automation by lmiranda
Description
This project aims to build a complete end-to-end Machine Learning pipeline running entirely on Kubernetes, using Go, and containerized ML components.
The pipeline will automate the lifecycle of a machine learning model, including:
- Data ingestion/collection
- Model training as a Kubernetes Job
- Model artifact storage in an S3-compatible registry (e.g. Minio)
- A Go-based deployment controller that automatically deploys new model versions to Kubernetes using Rancher
- A lightweight inference service that loads and serves the latest model
- Monitoring of model performance and service health through Prometheus/Grafana
The outcome is a working prototype of an MLOps workflow that demonstrates how AI workloads can be trained, versioned, deployed, and monitored using the Kubernetes ecosystem.
Goals
By the end of Hack Week, the project should:
Produce a fully functional ML pipeline running on Kubernetes with:
- Data collection job
- Training job container
- Storage and versioning of trained models
- Automated deployment of new model versions
- Model inference API service
- Basic monitoring dashboards
Showcase a Go-based deployment automation component, which scans the model registry and automatically generates & applies Kubernetes manifests for new model versions.
Enable continuous improvement by making the system modular and extensible (e.g., additional models, metrics, autoscaling, or drift detection can be added later).
Prepare a short demo explaining the end-to-end process and how new models flow through the system.

issuefs: FUSE filesystem representing issues (e.g. JIRA) for the use with AI agents code-assistants by llansky3
Description
Creating a FUSE filesystem (issuefs) that mounts issues from various ticketing systems (Github, Jira, Bugzilla, Redmine) as files to your local file system.
And why this is good idea?
- User can use favorite command line tools to view and search the tickets from various sources
- User can use AI agents capabilities from your favorite IDE or cli to ask question about the issues, project or functionality while providing relevant tickets as context without extra work.
- User can use it during development of the new features when you let the AI agent to jump start the solution. The issuefs will give the AI agent the context (AI agents just read few more files) about the bug or requested features. No need for copying and pasting issues to user prompt or by using extra MCP tools to access the issues. These you can still do but this approach is on purpose different.

Goals
- Add Github issue support
- Proof the concept/approach by apply the approach on itself using Github issues for tracking and development of new features
- Add support for Bugzilla and Redmine using this approach in the process of doing it. Record a video of it.
- Clean-up and test the implementation and create some documentation
- Create a blog post about this approach

There is a prototype implementation here. This currently sort of works with JIRA only.
Backporting patches using LLM by jankara
Description
Backporting Linux kernel fixes (either for CVE issues or as part of general git-fixes workflow) is boring and mostly mechanical work (dealing with changes in context, renamed variables, new helper functions etc.). The idea of this project is to explore usage of LLM for backporting Linux kernel commits to SUSE kernels using LLM.
Goals
- Create safe environment allowing LLM to run and backport patches without exposing the whole filesystem to it (for privacy and security reasons).
- Write prompt that will guide LLM through the backporting process. Fine tune it based on experimental results.
- Explore success rate of LLMs when backporting various patches.
Resources
- Docker
- Gemini CLI

SUSE Observability MCP server by drutigliano
Description
The idea is to implement the SUSE Observability Model Context Protocol (MCP) Server as a specialized, middle-tier API designed to translate the complex, high-cardinality observability data from StackState (topology, metrics, and events) into highly structured, contextually rich, and LLM-ready snippets.
This MCP Server abstract the StackState APIs. Its primary function is to serve as a Tool/Function Calling target for AI agents. When an AI receives an alert or a user query (e.g., "What caused the outage?"), the AI calls an MCP Server endpoint. The server then fetches the relevant operational facts, summarizes them, normalizes technical identifiers (like URNs and raw metric names) into natural language concepts, and returns a concise JSON or YAML payload. This payload is then injected directly into the LLM's prompt, ensuring the final diagnosis or action is grounded in real-time, accurate SUSE Observability data, effectively minimizing hallucinations.
Goals
- Grounding AI Responses: Ensure that all AI diagnoses, root cause analyses, and action recommendations are strictly based on verifiable, real-time data retrieved from the SUSE Observability StackState platform.
- Simplifying Data Access: Abstract the complexity of StackState's native APIs (e.g., Time Travel, 4T Data Model) into simple, semantic functions that can be easily invoked by LLM tool-calling mechanisms.
- Data Normalization: Convert complex, technical identifiers (like component URNs, raw metric names, and proprietary health states) into standardized, natural language terms that an LLM can easily reason over.
- Enabling Automated Remediation: Define clear, action-oriented MCP endpoints (e.g., execute_runbook) that allow the AI agent to initiate automated operational workflows (e.g., restarts, scaling) after a diagnosis, closing the loop on observability.
Hackweek STEP
- Create a functional MCP endpoint exposing one (or more) tool(s) to answer queries like "What is the health of service X?") by fetching, normalizing, and returning live StackState data in an LLM-ready format.
Scope
- Implement read-only MCP server that can:
- Connect to a live SUSE Observability instance and authenticate (with API token)
- Use tools to fetch data for a specific component URN (e.g., current health state, metrics, possibly topology neighbors, ...).
- Normalize response fields (e.g., URN to "Service Name," health state DEVIATING to "Unhealthy", raw metrics).
- Return the data as a structured JSON payload compliant with the MCP specification.
Deliverables
- MCP Server v0.1 A running Golang MCP server with at least one tool.
- A README.md and a test script (e.g., curl commands or a simple notebook) showing how an AI agent would call the endpoint and the resulting JSON payload.
Outcome A functional and testable API endpoint that proves the core concept: translating complex StackState data into a simple, LLM-ready format. This provides the foundation for developing AI-driven diagnostics and automated remediation.
