| 摘 要： | 在任意计算机上重现用户的个性化计算环境。基于应用层虚拟化技术,在高速移动存储设备上保存用户的配置信息。在运行时,通过系统调用包裹技术截获这些资源的访问,再定向到移动存储设备上,在不影响性能和可靠性的前提下重现用户的个人计算环境。给出了该系统的原型实现及性能测试。测试结果表明:应用层虚拟化技术运行的开销只占用系统开销的0.5%。

| Abstract: | This paper presents a user-level virtualization method that reproduces the personal computing environment.The solution separates and saves personal information(including personal documents/folders,and applications' customizations) into a portable high-speed storage device.At run-time,the portable applications on the device will run in a user-level virtualization environment where some of the resources(registry,files/directories,environment variables,etc.) for accessing the APIs for this information are inte... |
