Xen通过一种叫做半虚拟化的技术获得高效能的表现(较少的效能损失,典型的情况下大约损失 2 ,在最糟的情况下会有 8 的效能耗损;与其它使用完全的虚拟化却造成最高到 20 损耗的其他解决方案形成一个明显的对比),甚至在某些与传统虚拟技术极度不友好的架构上(x86),Xen也有极佳的表现。与那些传统透过软件模拟实现硬件的虚拟机不同,在3.0版本及在Intel VT-X支援前的Xen需要让客座作业系统(guest operating systems)与Xen API进行连接。到目前为止,这样连结已经可以运用在NetBSD,GNU/Linux,FreeBSD和贝尔实验室的Plan 9系统上。在Brainshare 2005会议上,Novell展示了NetWare与 Xen的连通。与Windows XP连通的技术曾在Xen开发初期进行,但微软的协议未能允许它发布。Sun微系统公司也正积极研究Solaris与Xen的连结,使其能在Xen平台上运作。-his article is about the virtualization software.

In computing, Xen (pronounced /ˈ zɛ n/) is a virtual-machine monitor for IA-32, x86-64, Itanium and ARM architectures. It allows several guest operating systems to execute on the same computer hardware concurrently. The University of Cambridge Computer Laboratory developed the first versions of Xen as of 2010, the Xen community develops and maintains Xen as free software, licensed under the GNU General Public License (GPLv2).
