摘　　要：目前在虚拟监控器VMM(Virtual Machine Monitor)下还没有能高效方便地对GuestOS进程进行管理的工具。以VMM是Lguest,GuestOS是Linux为运行环境,实现了名为GPMU(Guest Processes Management Utilities)的VMM下GuestOS进程级的管理工具原型。GPMU在不改动GuestOS和对VMM性能影响尽可能小这两个前提下,通过直接在VMM中动态地按需获得GuestOS中进程描述符后对其操作来实现GuestOS进程级管理。实验结果表明GPMU的实现是正确有效的。还分析了GPMU的性能瓶颈并做了对应的优化,典型的管理操作时间缩短为原始实现中的41%,大幅提高了性能。Currently, there are no utilities to manage Guest OS process efficiently and conveniently on VMM. In this paper,we implement a prototype of process level Guest OS management utility, named as GPMU, in an operation environment taking Lguest as VMM and Linux as Guest OS. With two prerequisites, to ensure no modification on the Guest OS and to minimise the performance degradation of VMM, the GPMU implements the process level Guest OS management via operating the process descriptors of Guest OS dynamically obtained from VMM directly and on demand. Our experiments demonstrate the correctness and effectiveness of the implementation of GPMU. We also analyse GPMU＇ s per- formance bottleneck and make some corresponding optimisations. As the result, the typical management operation time is reduced to 41% of the original implementation, the performance is improved dramatically.
