Open Source Summit + Embedded Linux Conference North America 2026

AMD, in collaboration with the Xen community, continues to advance efforts to make the Xen hypervisor safety-certifiable to ISO 26262 ASIL D and IEC 61508 SIL 3. The project has progressed from Safety Concept Approval toward the final certification phase.

This presentation will share practical lessons learned, including how we structure requirements and architecture specification documents to make them easier to review for Open Source experts. It will describe the tools and processes we use to maintain end-to-end traceability and explain how we leverage GitLab to automate requirements-based testing and verification pipelines.

We will also address the remaining challenges on the path to completion, including code coverage and FMEA. In particular, we will explain why achieving comprehensive code coverage is uniquely challenging for a widely used Open Source project such as Xen and outline the strategies we are applying to meet 100% code coverage targets.

Finally, we will describe our approach to FMEA (Failure Mode and Effects Analysis) and how it evolved to better align with existing upstream Xen failure-handling practices.
