SUMMARY:XCP-ng State of the Union
DESCRIPTION: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.\n 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.\n 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.\n 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.

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

SUMMARY:Initial Evaluation of Xen on the Renesas R-Car X5H Automotive SoC
DESCRIPTION: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.

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

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

SUMMARY:Xen in Automotive: Challenges and Lessons Learned Toward Safety Certification
DESCRIPTION: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.

SUMMARY:Securing Consolidated ICS Platforms with Xen - Meeting IEC 62443 Isolation Requirements
DESCRIPTION: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.

SUMMARY:Robots Among Us: a Least-Privilege Xen Architecture for Safe Humanoid Robots
DESCRIPTION:Humanoid robots are poised to become one of the defining technologies of the next decade\, with explosive growth projected across applications from hazardous industrial work to elderly care. They are also emerging as a promising new frontier for embedded virtualization. A single robot must fuse safety-critical motion control\, real-time sensor processing\, and rich AI workloads onto one heterogeneous platform. Real-time is critical: a humanoid robot that misses a deadline can fall\, or injure someone. Safety is also essential\; Xen must split responsibilities into separate domains\, each granted only the permissions it needs. This presentation will show how these pieces come together into a virtualization architecture for humanoid robots. It will detail the permissions assigned to each domain\, and explain why minimizing privilege is essential to both Safety and Security in a machine that shares physical space with people. We will also discuss how Xen enforces strict isolation and bounded latency across multiple architectures to make the next generation of humanoid robots safe\, responsive\, and dependable.

SUMMARY:Toward Reproducible OSS Reference Integration: Challenges in Automotive Xen-on-Arm BSP Integration
DESCRIPTION: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.

SUMMARY:ARINC 653 on Xen: A Unikraft Safety Architecture
DESCRIPTION:This talk presents a safety-critical architecture built entirely on the open-source Xen hypervisor\, Linux and Unikraft unikernel(s) as self-contained per-partition runtimes. We cover how this environment is a basis for implementing the ARINC 653 avionics standard\, static configuration\, and how a control domain pattern provides system management without Dom0 privileges. We discuss real challenges encountered — debug/trace without xl\, scheduler extensions for fault tolerance scenarios\, and device tree validation at boot — and identify areas where Xen community collaboration would accelerate safety-relevant capabilities.

SUMMARY:Managing per-guest resources in Xen
DESCRIPTION:The Xen hypervisor needs to manage several resources for each guest\, each of those requiring the hypervisor to allocate memory for this task. In order to limit the amount of memory needed\, most resources are limited\, e.g. via guest configuration. There is an alternative approach: instead of limiting each resource individually\, manage all resources via a common resource management\, allowing more flexibility for the guests. This presentation is a followup of a related design session at the Xen summit 2022.

SUMMARY:Secure Inter-Domain Communication: Implementing VSOCK over Xen Argo
DESCRIPTION:Xen Argo provides a robust mechanism for inter-domain communication\, offering strong isolation compared to traditional shared memory approaches. However\, its message-based API creates a portability barrier for standard POSIX applications. In this session\, I will present the realization of a new Linux kernel module that solves this challenge by implementing a complete VSOCK transport layer over Xen Argo. By exposing Argo through the standard AF_VSOCK interface\, we enable existing socket-based applications to run over Argo channels\, supporting both datagrams and reliable data streams (SOCK_STREAM) without code modification. Building upon initial designs\, we will dive deep into the kernel-level challenges to achieve a fully functional TCP-like stream over Argo's asynchronous rings. Key technical topics include: Realizing the Connection-Oriented Handshake: Mapping the POSIX TCP state machine (SYN/SYN-ACK) onto Argo\, including dynamic ring allocation with asymmetric hypervisor permissions to enable bidirectional traffic. Socket multiplexing: allowing concurrent logical connections over a single ring\, bypassing the strict 1:1 port-to-ring limitation.

SUMMARY:Improving Xen Traceability: More Than Just Livepatching
DESCRIPTION:The Xen livepatch framework provides a way to redirect calls to functions at runtime. It is useful when a running system needs to be updated without being stopped\, for example to apply security fixes. This session explores the possibility of extending this mechanism into a more tracing/debugging-friendly feature. Such an extension could allow more flexible use of existing Xen tracing tools such as xentrace. We will showcase this idea by sharing our recent experience using xentrace\, and discuss how a callback-based extension could make similar investigations easier in general. We would also like to discuss possible future extensions inspired by Linux tracing mechanisms such as kprobes/ftrace/eBPF which could make the feature more useful in practice.

SUMMARY:Compiler assisted Xen code elimination
DESCRIPTION:Xen makes use of various techniques to conditionally remove code from the final binary. From Kconfig\, to preprocessor tricks and DCE. This session explains a number of exotic key techniques used at AMD to drastically reduce code footprint with minimal changes to the source code. It highlights the set of constraints and requirements behind the new techniques and specific examples where they apply\, with metrics showing the gains.

SUMMARY:Xen Functional Safety Certification (an update)
DESCRIPTION:As AMD advances efforts to safety-certify the upstream Xen hypervisor\, this presentation provides an update on the past year's progress and roadmap. Xen\, a type-1 hypervisor with a self-contained codebase\, continues to gain traction in automotive and industrial applications due to its robust isolation\, security\, and virtualization capabilities. A central theme this year is reducing the certifiable code footprint through changes we intend to upstream in the near future. We apply several dead-code-elimination techniques\, such as gating management hypercalls (`MGMT_HYPERCALLS`)\, adding AMD restricted-feature configurations (`AMD_RESTRICTED_*`)\, and enabling linker garbage collection of unused sections. Alongside the code\, we have formalized Xen's domain-facing behavior into requirements and architecture specification\, both of which we plan to upstream as a shared\, verifiable baseline for the community. On verification\, we will share tests spanning domain-based tests\, a self-test framework\, GDB fault-injection test framework\, and QEMU qtest-based cases. Finally\, we present the current structural coverage on Arm64 and x86_64\, along with our roadmap to close the remaining gaps.

SUMMARY:Flight-Grade Xen: DO-178C Reverse Engineering for an example in list.h
DESCRIPTION:What does the term “Low Level Requirement” (LLR) mean to Xen? This talk provides an update to the ongoing work of Xen’s Functional Safety Working Group in the form of a worked case study for a challenging example: list.h We will show 1) When we should use a technique called “requirements mapping” (to reuse requirements rather than invent them ourselves) 2) How to test the preprocessor macros and occasional static inline functions in our list.h example to satisfy the DO-178C’s LLR-to-verification “trace data” obligations 3) How to produce a subject matter expert (SME) to review list.h LLRs (i.e.\, for “necessary and complete LLR”)\, via a training course about its RCU algorithm and the requirements behind that algorithm. We hope to engage the broader Xen community’s SMEs by focusing not on “FuSa” specifically\, but more broadly on “How does Xen really work?”

SUMMARY:Safety Cases as Data: The SPDX Functional Safety Profile and Lessons from Zephyr
DESCRIPTION:Xen and Zephyr are walking parallel paths toward functional safety within the Linux Foundation\, and both face the same problem: a safety case is a large\, manually maintained argument that drifts the moment the design changes\, and is hard to exchange between the projects\, suppliers\, and integrators who depend on it. This talk shares where Zephyr has gotten with a data-driven approach\, and opens a conversation about what it could mean for Xen. We start with SPDX 3.1's Functional Safety profile\, which gives the safety case a machine-readable form: requirements and their refinement\, verification activities\, pass/fail evaluations\, evidence\, and assumptions of use\, expressed as a graph that tools can produce\, exchange\, and check. We then show how Zephyr leverages it in practice—generating a "safety SBOM" from project content rather than assembling a safety case by hand\, recomputing verdicts as code evolves\, and detecting which evidence has gone stale.

SUMMARY:Display Para-Virtualization
DESCRIPTION:In recent years\, GPU para-virtualization on Xen has evolved to support increasingly complex automotive workloads. While prior work focused on graphics and compute virtualization\, display para-virtualization introduces new challenges due to its interaction with hardware composition pipelines and real-time requirements. In this session\, Ray presents his team’s latest work on display para-virtualization\, focusing on Multi-Plane Overlay (MPO) virtualization and the Virtual Primary Plane (vPP). These mechanisms extend the VirtIO GPU model to enable guest VMs to utilize host display hardware. He explains how MPO virtualization exposes multiple display planes to guest VMs\, allowing composition to be offloaded to hardware. The vPP abstraction provides a stable primary display surface\, decoupling guest behavior from host specifics. He also discusses GPU recovery integration and outlines validation approaches and future directions.

SUMMARY:Preparing Xen on Arm for VHE-Always Hardware
DESCRIPTION:Future Arm CPUs are evolving toward systems where Virtualization Host Extensions (VHEs) are always enabled. This talk shows how Xen can adapt to the next generation of Arm hardware while continuing to support today’s programmable-VHE and non-VHE systems. We will walk through the engineering work required to make Xen bootable\, and upstreamable on VHE-always platforms. The challenge goes far beyond early boot. We’ll cover VHE changes assumptions around EL2 bring-up\, system-register access\, MMU setup\, exception and trap routing\, timers\, interrupts\, and host/guest world switching. Attendees will learn how Xen detects and selects VHE policy during boot and secondary CPU bring-up\; how vhe=on/off/auto supports different platform capabilities\; and how EL1/EL2 system-register abstractions help reduce fragile VHE-specific conditionals. We will also cover the areas most likely to expose hidden assumptions\, including MMU state\, timer delivery\, GICv2/GICv3 virtualization\, and VHE-sensitive save/restore paths. Finally\, we will discuss the path from an initial homogeneous Dom0-boot prototype with basic timer and interrupt support to product-quality SMP\, testing\, and platform validation.

SUMMARY:Xen on RISC-V: From Dom0less to xl
DESCRIPTION:The RISC-V port of the Xen hypervisor has been progressing over the past year. This session gives a practical status update on where the port stands today\, covering the two main use cases: dom0less deployments for embedded and safety-critical workloads\, and dom0 with the xl toolstack for more traditional virtualization scenarios. We will walk through what works\, what is still in progress\, and what the remaining gaps are with a live demo to show the port running.
