With the rapid development of desktop virtualization technology ,this article selects the open source Xen virtualization software platform as the core platform ,to design and build the desktop virtual experiment . The“helloworld”operating system is designed ,and the experimental environment is installed in the process of experiment .At the same time ,the CPU and memory are running .As the operating is in the environment after breaking up ,users can remote access to virtual desktops .Aiming at the basic condition of university students , the experimental process with perfect theory ,and strong operability is designed .%选用开源平台Xen虚拟化软件作为核心平台，设计搭建桌面虚拟化实验。通过对helloworld操作系统的配置，实现了硬盘（安装环境）、CPU与内存（运行环境）、外设（操作环境）的物理拆分，使用户可以远程访问虚拟桌面。针对高校学生的基本情况设计了理论完善、操作性强的实验流程。
