The Xen Project product offering
Product offeringCore offering
The Xen Project develops and distributes the Xen Project Hypervisor, a Type 1 (bare-metal) open-source hypervisor that enables secure, stable, and performant virtualization across data center, cloud, embedded, automotive, and desktop environments. It also maintains supporting sub-projects including XCP-ng (turnkey virtualization platform), XAPI (enterprise toolstack), HVMI (security introspection), MirageOS and Unikraft (unikernel frameworks), and Windows PV Drivers. The software is released free of charge under open-source licensing via the Linux Foundation, with commercial products, support, and services delivered independently by ecosystem partners.
Product overview
The Xen Project is an open-source hypervisor ecosystem governed by the Linux Foundation, offering a modular architecture centered on the Xen Project Hypervisor as the core product. The portfolio includes XCP-ng as a turnkey virtualization platform built on the hypervisor with the Xen API, HVMI for security introspection, MirageOS and Unikraft for unikernel development, Windows PV Drivers for paravirtualized Windows support, and XAPI as an enterprise management toolstack. A dedicated Embedded & Automotive vertical focuses on safety-critical applications using VirtIO and real-time operating systems. Over 10 million users leverage the platform with an ecosystem of more than 2000 commercially certified partners.

The Xen Project partnerships and signals
Strategic signalPartnerships
13 partnerships are on record, tiered flagship, significant and core.
- Panasonic Automotive SystemsflagshipPanasonic Automotive Systems has led the global initiative to standardize VirtIO device virtualization technology for automotive applications since 2018. The initiative secured industry-wide endorsement from Honda, Mazda, Mitsubishi, Nissan, and Toyota, along with multiple technology companies. Panasonic completed development of a VirtIO-compliant in-vehicle software platform for Cockpit Domain Controllers, enabling hardware-agnostic software development for Software-Defined Vehicles.
- Ford Motor CompanysignificantFord joined the Xen Project in June 2025 and made contributions to Xen 4.21 to facilitate automotive safety certifications for use in vehicles, industrial settings, and potentially aviation.
- AMDcoreAMD is listed as a member and logo partner on the Xen Project website, indicating active contribution and integration support for AMD architecture within the Xen hypervisor.
- ARMcoreARM is a Xen Project member company contributing to the project, particularly in safety-critical systems and ARM architecture support for embedded and automotive use cases.
- Amazon Web Services (AWS)coreAWS is a member and logo partner. Contributions from AWS engineers (e.g., Amazon engineers at Xen Summit talks) and use of Xen in AWS infrastructure highlight the deep integration.
- EPAM SystemssignificantEPAM has developed a Xen-powered virtual cockpit solution connecting the infotainment and safety sides of vehicles. EPAM was featured at the AGL (Automotive Grade Linux) booth and contributes to advancing open-source automotive virtualization.
- Ford Motor CompanysignificantFord joined the Xen Project in June 2025 and contributed to Xen 4.21 to facilitate automotive safety and other delicate environments. The collaboration aims to support safety certifications for use in vehicles, industrial settings, and potentially aviation.
- HondasignificantHonda is part of the industry-wide endorsement for Panasonic's VirtIO device virtualization standardization initiative for automotive applications, alongside Mazda, Mitsubishi, Nissan, and Toyota.
- Linux FoundationcoreThe Xen Project is a Linux Foundation Collaborative Project, governed under the Linux Foundation's umbrella which provides neutral, trusted governance, administrative support, and a framework for community scaling.
- VatessignificantVates develops Xen Orchestra, a complete web UI for controlling XCP-ng and Xen-based infrastructure. Vates participates at Xen booths at FOSDEM alongside Citrix.
- Citrix (XenServer)significantCitrix XenServer is built on Xen and is a major commercial distribution. Citrix re-entered the mainstream virtualization market with XenServer 9 preview. Citrix participates at Xen Project booths at events.
- XCP-ngsignificantXCP-ng is a turnkey virtualization platform built on the Xen Project Hypervisor using the Xen API (XAPI). It is a key sub-project of the Xen ecosystem providing a complete open-source alternative.
- Automotive Grade Linux (AGL)significantXen plays a key role in the Automotive Grade Linux Software-Defined Vehicle reference platform, supporting mixed-criticality workloads with VirtIO and real-time OSes like Zephyr.

The Xen Project competitors and assessment
Company assessmentBroad incumbents
- Microsoft Hyper-V: Microsoft's Type 1 hypervisor integrated with Windows Server. Competes with Xen for enterprise server virtualization workloads, particularly in Windows-centric and hybrid cloud environments.
- Nutanix AHV: Acropolis Hypervisor, Nutanix's KVM-based hypervisor bundled with the Nutanix hyperconverged infrastructure platform. Competes broadly in enterprise virtualization and is a frequent alternative to Xen-based Citrix XenServer deployments.
- Red Hat Virtualization (RHV): Enterprise virtualization platform built on KVM. Competes in the same enterprise server virtualization market as Xen-based commercial offerings, backed by Red Hat's enterprise support and distribution.
- VMware (Broadcom): The dominant commercial server virtualization platform and the primary enterprise competitor to Xen-based offerings such as Citrix XenServer and XCP-ng. Competes broadly across enterprise virtualization even though it is not open source.
Direct peers
- QEMU: Open-source machine emulator and virtualizer typically paired with KVM as the de facto open-source virtualization stack. Competes with Xen at the developer and open-source virtualization level, particularly for cross-architecture emulation and testing.
- Proxmox VE: Open-source virtualization management platform built on KVM and LXC. Directly competes with XCP-ng (the Xen-based turnkey stack) for the open-source enterprise virtualization and homelab market.
- KVM (Kernel-based Virtual Machine): Linux's native Type 1 hypervisor and Xen's most direct open-source competitor. KVM has effectively become the default open-source hypervisor across most Linux distributions and non-AWS hyperscalers, competing head-to-head with Xen for cloud and server virtualization workloads.
- Firecracker: AWS's open-source microVM based on KVM, used for serverless workloads in Lambda and Fargate. Represents the modern, lightweight virtualization approach that competes with Xen's cloud story and is developed by Xen's largest corporate backer.
Emerging players
- oVirt: Open-source virtualization management platform built on KVM, community-driven under the oVirt project. Competes with XCP-ng/XAPI as an open-source management layer for KVM-based virtualization in data center environments.
- Qubes OS: Security-focused desktop operating system built directly on Xen. While not a direct commercial competitor, it represents a key Xen-based ecosystem use case in the security-first desktop segment and contributes back to Xen's CI testing.
