The Xen® hypervisor, the powerful open source industry standard for virtualization, offers a powerful, efficient, and secure feature set for virtualization of x86, x86_64, IA64, ARM, and other CPU architectures. It supports a wide range of guest operating systems including Windows®, Linux®, Solaris®, and various versions of the BSD operating systems. What is Xen? - Why Xen?
Xen powers most public cloud services and many hosting services, such as Amazon Web Services, Rackspace Hosting and Linode. Commercial virtualization products such as Oracle VM and XenServer are built on top of Xen, as well as desktop virtualization solutions such as Qubes OS and XenClient. See case studies for detailed Xen user studies or our eco-system map for vendors, products, projects, services and research. From Linux 3.0 onwards, all of the code necessary to run Linux as the Xen management OS and as a Xen guest, is part of the Linux kernel.
The history of the Xen.org community and Xen hypervisor project is available on the Xen history page. If you are new to the Xen.org community or interested in understanding how to interact with the community, please read the New to Xen Guide.

Getting Xen
For a user there are several ways to get Xen: as a Xen appliance, through a Linux distribution and from source. The appliance model provides Xen as a tested installable image: Xen.org provides an appliance through the XCP project. Project Kronos will deliver Xen packages into Linux distributions: when completed, you will get all Xen packages that are in the Xen appliance through your favourite distro's package management system. If you are interested in modfiying Xen, you can get Xen as a source distribition from the Xen Hypervisor project. However you will need to build Xen from source.
Xen Projects
The open source Xen community currently delivers several solutions for use by customers, software and hardware vendors, researchers, developers, hobbyists, etc..The Xen.org community also supports a variety of solutions built for and around the Xen Hypervisor.
