GeezerVison is showing xenproject.org — Xen Project A Linux Foundation Project Open source virtualization for systems that demand isolation and control.Xen is an open source hypervisor for infrastructure, embedded, security-sensitive, and virtualization platforms that need clear separation and long-term control.     Applications Workloads and services running in user space. Guest systems Isolated operating systems and runtimes. Xen hypervisor The thin virtualization control layer that provides isolation and manages hardware. Hardware Physical compute resources. Built in the Open A project you can evaluate in the open.Governance, security handling, and testing resources are published so technical teams can inspect how the project works. Security Published response processSecurity reporting and response expectations are documented for users and vendors. Security policy CI Public testing resourcesCI resources and status information are available for contributors and evaluators. CI resourcesWhy Xen matters now Modern platforms still need a strong virtualization layer.For technical evaluators, Xen is most relevant where isolation, openness, long-term platform work, and security-sensitive engineering matter. Isolation as a foundationXen is built around a hypervisor layer that separates guest systems from the underlying platform. Open engineering modelGovernance and contribution paths are visible to organizations and individual engineers. Security-sensitive platformsSecurity policy, vulnerability reporting, and related project work are part of the evaluation path. Where Xen fits Built for engineers working close to the platform.Xen is strongest when teams need to reason carefully about virtual machines, hardware, operating systems, and trust boundaries. Cloud and infrastructureXen projects include the hypervisor and toolstack work used to build virtualization platforms. Embedded and automotiveThe Embedded & Automotive project describes Xen for systems that need isolation, real-time support, and fault tolerance. Introspection and security toolingHVMI focuses on real-time monitoring and protection for virtualized environments. Specialized operating systemsMirageOS and Unikraft show how Xen ecosystem projects support focused, lightweight systems work. Architecture A clear boundary for platform control.Xen sits between hardware and guest systems. That position gives platform teams a place to make virtualization, isolation, and control decisions without treating the operating system as the whole boundary. Guests Virtualized systems stay above the hypervisor boundary. Hardware Platform integration stays visible to teams that need control. Try Xen Start a Xen guestInstall Xen, start a guest, and verify it is running. Debian AMD64 example. Project areas Explore the Xen project ecosystem.Key project areas are available through direct links so teams can scan capabilities and go deeper where relevant. Embedded & AutomotiveOpen source virtualization for embedded and automotive systems that need isolation, mixed workloads, hardware-aware boundaries, and long-term platform control. HVMIExplore Xen Project's Hypervisor Memory Introspection (HVMI). Learn how HVMI enhances security by providing real-time monitoring and protection for virtualized environments. HypervisorDiscover Xen Hypervisor, the open-source virtualization platform. Mirage OSMirageOS is a library operating system that constructs unikernels for secure, high-performance, low-energy footprint applications. XAPIThe XAPI project is an enterprise-ready toolstack for use with the Xen Project hypervisor. XCP-ngXCP-ng (Xen Cloud Platform – new generation) is a turnkey virtualization platform built on the Xen Project Hypervisor and using the Xen API (XAPI). It is typically managed with Xen Orchestra, an agentless, multi-cluster web interface that provides management, monitoring, and backup capabilities. Xen in automotive A major year for Xen in automotiveAt Xen Summit 2025, Stefano Stabellini highlighted a period of major automotive momentum for Xen, including new members, safety progress, and deeper collaboration with Automotive Grade Linux. Stefano Stabellini, AMD Xen Summit 2025 Xen in Safety Systems: Hardware Domain and Control Domain separation  0:57 Safety collaboration Open source safety engineering, built together.The Xen Safety Committee gives Premier Plus members a maintained foundation of requirements, tests, tooling, evidence, and process documentation, giving their own certification-oriented programs a substantial head start. Safety CommitteeCoordinate certification-oriented engineering. Shared foundationBuild on maintained requirements, tests, tooling, evidence, and process documentation. Premier Plus participationHelp set priorities and give downstream safety programs a head start. Members Sustained by organizations with a stake in open virtualization.Members help sustain shared project infrastructure, events, trademark stewardship, and ecosystem coordination.           Driving virtualization forward Latest from the Xen ProjectRecent releases, initiatives, events, and technical work from across the project.  Release Xen 4.22: Strengthening Open Source Virtualization for Cloud, Embedded, and Automotive SystemsXen 4.22 adds modern hardware support, Arm improvements, continued RISC-V progress, Xenstore scalability updates, and a five-year security support lifecycle. Event 🛠️ Xen Summit 2025: Find Your Place in the Future of VirtualizationThe annual Xen Summit is right around the corner, and there has never been a more exciting time to be part of the Xen Project. As enterprise and industrial needs shift… Xen at FOSDEM: Real-World Conversations About Xen and KVMWe just wrapped up a weekend at FOSDEM 2026 where Xen and XCP-ng both had dedicated booths. This was my first time at FOSDEM and the legend lived up to the hype. It was… People behind the project Built by a global community.Maintainers, contributors, users, and researchers work together to build Xen and put it to work across cloud, embedded, automotive, and security-sensitive systems. Talks, design sessions, and conversations from the community’s gathering near Munich. Explore the Summit recapWas this page helpful? |
