GovernanceA Linux Foundation Project
Xen is an open source hypervisor for infrastructure, embedded, security-sensitive, and virtualization platforms that need clear separation and long-term control.

CI resourcesWhy Xen matters now
For technical evaluators, Xen is most relevant where isolation, openness, long-term platform work, and security-sensitive engineering matter.
Xen is built around a hypervisor layer that separates guest systems from the underlying platform.
Governance and contribution paths are visible to organizations and individual engineers.
Security policy, vulnerability reporting, and related project work are part of the evaluation path.
Where Xen fits
Xen is strongest when teams need to reason carefully about virtual machines, hardware, operating systems, and trust boundaries.
Xen projects include the hypervisor and toolstack work used to build virtualization platforms.
The Embedded & Automotive project describes Xen for systems that need isolation, real-time support, and fault tolerance.
HVMI focuses on real-time monitoring and protection for virtualized environments.
MirageOS and Unikraft show how Xen ecosystem projects support focused, lightweight systems work.
Architecture
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
Install Xen, start a guest, and verify it is running.
sudo apt install xen-system-amd64# Reboot into Xen and prepare /etc/xen/guest.cfgsudo xl create /etc/xen/guest.cfgsudo xl listDebian AMD64 example.
Project areas
Key project areas are available through direct links so teams can scan capabilities and go deeper where relevant.
Open source virtualization for embedded and automotive systems that need isolation, mixed workloads, hardware-aware boundaries, and long-term platform control.
Explore Xen Project's Hypervisor Memory Introspection (HVMI). Learn how HVMI enhances security by providing real-time monitoring and protection for virtualized environments.
Discover Xen Hypervisor, the open-source virtualization platform.
MirageOS is a library operating system that constructs unikernels for secure, high-performance, low-energy footprint applications.
The XAPI project is an enterprise-ready toolstack for use with the Xen Project hypervisor.
XCP-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.
New safety initiative
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.
Coordinate certification-oriented engineering.
Build on maintained requirements, tests, tooling, evidence, and process documentation.
Help set priorities and give downstream safety programs a head start.
