为实现在任意计算机上重现用户的个性化计算环境,本文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个性化计算环境的配置信息,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。本文同时给出了该系统的原型实现及性能测试,测试结果应用层虚拟化技术运行的开销只占用系统开销的0.5%。
In order to realize the personalized computing environment for users to reproduce on any computer, based on the application layer virtualization technology, the configuration information of the user’s personalized computing environment is saved on the high-speed mobile storage device, and intercepted by the system call package technology at runtime Resource access is redirected to the removable storage device to recreate the user’s personal computing environment without compromising performance or reliability. At the same time, this paper presents the prototype implementation and performance testing of the system. The test results show that the overhead of application-layer virtualization technology only takes up 0.5% of the system overhead.
