Xen Summit 2026

Hypervisors are used in automotive SoCs to consolidate multiple operating systems and provide system isolation.
However, publicly available reports on Xen running on automotive Arm SoCs are still limited, especially regarding basic performance characteristics and evaluation setups.
Therefore, sharing practical evaluation methods and measurement considerations based on real hardware is important when considering the use of Xen in the automotive domain.

This session introduces an initial evaluation effort for Xen on the Renesas R-Car X5H, an automotive SoC featuring 32 Arm Cortex-A720AE cores.
Using a native Linux environment as a baseline, it discusses the evaluation setup, measurement conditions, benchmark design, and preliminary results available at the time of the presentation
The session also covers considerations during the setup of the evaluation environment, basic configuration topics such as CPU assignment and domain configuration, practical issues encountered during measurement, and areas for further investigation in future evaluations.
