XCP-ng State of the Union

Tuesday September 15, 2026 10:00am - 10:30am PDT

HEADS office - Gold Room

Nearly three years after Broadcom's takeover of VMware, the community around Xen and XCP-ng looks different. This is the weather report for that community, not the product roadmap.
We will walk the climate: the wave of VMware refugees arriving on the forum and in production, where they get stuck and what pulls them through; who is actually contributing to an open type-1 hypervisor, and why the reviewer bottleneck matters more than any single feature; and the widening ecosystem of partners, integrators, and distributions now betting on Xen.
We will look at why Xen still exists when the hyperscalers moved on, what "digital sovereignty" really means once you get past the slogans, and where the project is heading, from the datacenter out to Arm, RISC-V, and the safety-certified edge.
This one is for the room that lives in this code every day: a step back from your own corner of the tree to the state of the whole community and ecosystem around it. Expect an honest forecast, clouds included.

Enabling Mixed-Critical Automotive Workloads on R-Car Gen5 (X5H) with Xen

Tuesday September 15, 2026 10:45am - 11:15am PDT

HEADS office - Gold Room

As automotive platforms shift to centralized compute, the key challenge is consolidating mixed-critical workloads while ensuring isolation, predictability, and visibility into cross-domain interference.
This session presents a Xen-based implementation on Renesas R-Car Gen5 (X5H) using a Dom0-managed architecture to run Android IVI, Linux service/AI workloads, and real-time control with defined domain partitioning.
We cover system architecture, bring-up, and integration challenges, including CPU allocation and device assignment trade-offs. We also demonstrate on-device AI inference using LLaMA 3.2 and Qwen models in dedicated Xen domains, focusing on coexistence with IVI and real-time workloads.
Finally, we present a cross-domain observability framework using xentop and a custom dashboard, providiāng visibility into CPU usage and interference patterns. The session shares practical insights and measured behavior for deploying mixed-critical workloads on X5H

Initial Evaluation of Xen on the Renesas R-Car X5H Automotive SoC

Tuesday September 15, 2026 11:15am - 11:45am PDT

HEADS office - Gold Room

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.

Beyond the Reference Board - Porting AGL SoDeV's Xen Multi-Domain Architecture from V4H to RPi5

Tuesday September 15, 2026 12:15pm - 12:45pm PDT

HEADS office - Gold Room

AGL SoDeV's Xen multi-domain architecture -- Dom0less, DomD, and DomA -- was designed and validated on the Renesas R-Car V4H (Sparrow Hawk), the AGL reference platform. This talk shares our experience porting that architecture to the Raspberry Pi 5, a low-cost, widely available board, to make SDV prototyping accessible beyond specialized automotive silicon.
We walk through the concrete challenges encountered: GPU virtualization, where virtio-gpu alone is insufficient and virgl is required for 3D acceleration under a Xen DomD-backed setup; securing virtio-mmio transport with Xen 4.18 grant tables in a driver-domain configuration; and resolving Android guest (DomA) boot failures rooted in autostart defaults, a config-variable regression, and GPT label mismatches after reflashing. We also cover Yocto/kernel alignment between the reference workspace and downstream RPi5 layers, both pinned to Scarthgap 5.0 LTS.
Beyond the fixes, we discuss what changes and what stays the same when porting a safety-oriented, automotive-grade Xen design from a reference SoC to commodity hardware -- and what that means for lowering the barrier to SDV experimentation and community contribution.

Thermal Management in the Xen hypervisor for Automotive: Challenges and a Hybrid Approach

Tuesday September 15, 2026 4:00pm - 4:30pm PDT

HEADS office - Gold Room

The automotive industry is rapidly increasing its demand for hardware virtualization and is increasingly interested in the Xen Hypervisor as a key solution. This shift toward highly integrated systems introduces new challenges, particularly in thermal management, which are critical concerns for the automotive industry.
Xen hypervisor currently lacks a standardized framework for system-level thermal control, unlike traditional single-OS systems such as Linux. Thermal management in virtualized environments requires coordinated control across multiple components, but responsibilities are distributed across multiple layers—from firmware to hypervisor and operating systems—while no single component has full system visibility or authority over global coordination, where system-level control becomes significantly more difficult.
In this session, we present key challenges focusing on this gap and share our perspective on possible architectural directions, including a hybrid control approach that combines centralized policy concepts with distributed control. Through the session, we aim to engage the Xen community and encourage further exploration toward practical and standardized solutions.

Xen in Automotive: Challenges and Lessons Learned Toward Safety Certification

Tuesday September 15, 2026 4:30pm - 5:00pm PDT

HEADS office - Gold Room

As next-generation automotive systems increasingly demand hardware virtualization, several automotive companies are interested in Xen Hypervisor as a key solution. Understanding what the automotive industry truly needs from Xen is a critical topic for the Xen Community.

In this session, we present nine categories of automotive requirements for Xen Hypervisor — Isolation, VM Lifecycle, Device Virtualization, Security, Scheduling, Performance, Development Environment, Power Management, and Functional Safety — these requirements come from
production projects at Renesas.

Among them, Safety stands out as the most prioritized requirement in automotive projects. We will present our 18-month Xen Safety qualification activities, our approach to functional safety (ISO 26262) for Xen, key technical challenges we have encountered, and our planned contributions to the Xen Community.

Securing Consolidated ICS Platforms with Xen - Meeting IEC 62443 Isolation Requirements

Tuesday September 15, 2026 5:00pm - 5:30pm PDT

HEADS office - Gold Room

Industry 4.0 and OT/IT convergence are consolidating industrial systems onto single-SoC multicore platforms that combine real-time control, safety monitoring, HMI, and cloud connectivity. This cuts cost and complexity, but sharing hardware between trusted and untrusted software makes cybersecurity isolation the central challenge: a compromise of one component must not open a path into another. IEC 61508 requires freedom from interference (FFI), yet on a connected platform that guarantee holds only if the isolation layer is secure first. This presentation shows how the Xen hypervisor meets the challenge—using its Type-1 architecture, strong VM isolation, and Flask/XSM framework to separate safety-critical workloads from less-trusted components. Built under a secure development lifecycle aligned with IEC 62443-4-1 and mapped to the 4-2 component requirements at Security Level 4 (SL 4), the same isolation that satisfies IEC 62443 underpins the IEC 61508 FFI argument—keeping safety and security separately evaluated on a shared mechanism. The talk also maps IEC 62443 requirements to the EU Cyber Resilience Act.
