| 摘 要： | 利用虚拟机的隔离性、封装性、透明性等特点，提出了在服务系统上利用虚拟机中间件来实现服务系统的性能QoS和安全QoS，通过定义计算域、可信程序和节点负载来实现任务运行环境的选择，运行环境的隔离；通过形式化的方法证明了基于虚拟机运行环境的高安全性；通过虚拟机迁移技术实现计算域群内虚拟机的整体迁移以达其高效性。最后利用仿真实验验证了基于虚拟机中间件服务系统的高安全性和高效性。

| Abstract: | According to the virtual machine＇ s isolating, packaging, transparency and other characteristics, virtual machine middleware is proposed to guarantee the performance of QoS and QoS in the service system. With the definition of the calculation domain, credibility program and load node, and task＇s operating environment can be selected and environment also is isolated. High-security of running environment based on the virtual machine is proved through the formal method, and the overall migration of virtual machine can be achieved within the calculation domain by using virtual machine migration technology. Finally, simulation experiment shows that the service system based on virtual machine middleware are of high security and efficiency. |
