摘　　要：针对当前各类虚拟机监控器(VMM)在定制虚拟机执行环境过程中灵活性不足、可用性不强方面的问题,提出并设计了一种用户动态配置虚拟机执行环境的模型,并在协作型VMM之上进行了实现。结合Intel VT-x技术的实现机制,充分利用虚拟机控制结构(VMCS)中的执行控制域特性,通过为用户提供接口,对虚拟机配置文件进行操作,实现对虚拟机执行环境的实时动态配置。用户利用该模型能够快速构建具有不同运行时特性的虚拟机执行环境。测试结果表明,该模型能够提高VMM的可用性。There are some deficiencies in the current Virtual Machine Monitor（VMM） that could not customize different virtual machine execution environment flexibly.This paper illustrated the feasibility of designing and implementing the dynamic model to make better use of the VMM,and then presented a model to design a user-configured virtual machine execution environment and implemented it upon the cooperative VMM.The model made full use of the control domains in Virtual Machine Control Structure（VMCS） configuration progress.With this model,users can change the features of the virtual machine execution environment for real-time dynamic configuration,and build virtual machines with different characteristics based on a VMM at the same time.The test results show that the model can improve the availability of the VMM.
