What is the Xen Project?
The Xen Project is the home for several virtualization related open source projects, and Xen Project is the new name for the Xen open source community. The Xen Project develops virtualization technologies powering the world's largest clouds in production and is the foundation of many commercial products. Technology developed by the Xen Project powers public clouds such as Amazon Web Services, Rackspace Public Cloud, and many others. Examples of Xen based server products include Huawei UVP, Oracle VM and Citrix XenServer. Examples of client products and appliances include QubesOS, Citrix XenClient and Netscaler. The Xen Project is 10 years old, and the technology it has created is mature and its stability and versatility is second to none.

Source code and projects hosted on xenproject.org are classified with an Export Control Classification Number (ECCN) if it is believed to correspond to an entry in the Commerce Control List (CCL) and subject to the EAR. All xenproject.org software is published in a publicly available source code form. Publicly available software is only subject to the EAR when it is classified as ECCN 5D002 or 5D992.
Where not stated otherwise on the download page, products are classified as ECCN 5D002, and exported by the Xen Project under the TSU exception in EAR 740.13(e), which applies to software containing or designed for use with encryption software that is publicly available as open source. Exception TSU further provides that "Posting encryption source code and corresponding object code on the Internet (e.g., FTP or World Wide Web site) where it may be downloaded by anyone neither establishes "knowledge" of a prohibited export or reexport for purposes of this paragraph, nor triggers any "red flags" necessitating the affirmative duty to inquire[...]". Note that exporters other than the Xen Project within the US may or may not be eligable for exception TSU, and it is each specific exporter's responsibility to understand and comply with all export regulations applicable within their jurisdiction.
A Linux Foundation Collaborative Project
Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems. By spreading the collaborative DNA of the largest collaborative software development project in history, The Linux Foundation provides the essential collaborative and organizational framework so project hosts can focus on innovation and results.
