Xen Summit 2026

Automotive SDV systems require multiple domains—IVI, instrument cluster, real-time, and service—to coexist on a single Arm SoC. Combining AGL, Zephyr, and Xen is a promising approach for OSS-based reference integration. The key challenge is turning this virtualized setup into a continuously buildable and reusable foundation.
In this talk, Kurokawa presents ongoing integration work with AGL, Zephyr, and Xen on an automotive Arm platform. He outlines key challenges, including Device Tree configuration, role separation among Dom0, the hardware domain, and driver domains, and VirtIO backend placement. A central question is how SoC-specific hardware should be assigned, shared, or abstracted across domains while maintaining consistency with BSP configurations.
He shares these challenges as practical feedback to the Xen community. Many are common issues as Xen expands into embedded and edge use cases. He discusses approaches in configuration, build, and testing, and provides actionable guidance for building maintainable OSS-based integration platforms.
