【摘要】：随着虚拟化技术的广泛应用,越来越多的企业运用虚拟机技术进行系统和服务器建设,但如何有效的监控多个物理机和部署在其上的大量虚拟机成为虚拟机管理的难点。虚拟器件的提出,虽然解决了传统企业信息系统发布和部署时环境兼容性、操作复杂度高和安全复杂度高的问题,但也给信息系统的部署带来了平台兼容、虚拟化平台兼容和物理体积三方面的局限性,管理员运用普通虚拟器件难以高效的管理大规模虚拟机。针对以上问题,本文在对商用虚拟器件进行深入研究的基础上,提出一种特殊的具有自维护功能的虚拟器件,称之为虚拟构件。在构件的设计中加入代理服务机制,采用代理服务机制的虚拟构件能够获得虚拟机内部运行情况,方便管理员进行细粒度的控制和维护。虚拟构件代理服务机制的主要思想为：通过在虚拟机内部设计代理服务模块,建立起虚拟机与物理机之间数据交互的通道,使得管理员能够获得虚拟机内部的数据,并能进行虚拟机操作管理。同时,代理服务机制加入了自维护规则集,并在虚拟机中布置感应器与效应器,对于基本的维护,管理员无需进行管理操作,就能实现自维护。为设计和实现上述目标,本文进行了以下几方面的工作： (1)虚拟构件运维模型的建立。主要分为虚拟构件和虚拟构件管理平台的设计。其中,虚拟构件包括虚拟构件元信息、维护规则集、感应器、效应器等。虚拟构件管理平台包括知识库、监视器、决策元、执行器等。 (2)对于数据传输模块,本文设计中加入了最小数据传递更新算法,确保传输数据的最小化,优化网络带宽,提高传输性能。并对算法进行了测试,实验结果表明算法的加入,对于集群虚拟机管理能明显提高效率。 (3)对虚拟构件管理平台监控模块进行界面开发,获得物理机和虚拟机的内部数据,便于管理员查看和管理。对自维护功能进行了演示程序展示。
[Abstract]:With the wide application of virtualization technology, more and more enterprises use virtual machine technology for system and server construction, but how to effectively monitor multiple physical machines and a large number of virtual machines deployed on them becomes the difficulty of virtual machine management. The introduction of virtual devices solves the problems of environment compatibility, high operation complexity and high security complexity when traditional enterprise information systems are published and deployed, but it also brings platform compatibility to the deployment of information systems. Due to the limitations of virtualization platform compatibility and physical volume, it is difficult for administrators to efficiently manage large virtual machines with common virtual devices. In order to solve the above problems, based on the in-depth study of commercial virtual devices, this paper proposes a special virtual device with self-maintenance function, which is called virtual component. The agent service mechanism is added to the design of the component, and the virtual component using the proxy service mechanism can obtain the internal running situation of the virtual machine, which is convenient for the administrator to control and maintain fine granularity. The main idea of the proxy service mechanism of virtual component is: through designing proxy service module in virtual machine, the channel of data interaction between virtual machine and physical machine is established, so that the administrator can obtain the data inside virtual machine. And can manage the operation of virtual machine. At the same time, the agent service mechanism adds the self-maintenance rule set, and arranges the sensor and the effector in the virtual machine. For the basic maintenance, the administrator can realize the self-maintenance without the need of the management operation. In order to design and achieve the above objectives, this paper has done the following work: 1) Establishment of virtual component operation and maintenance model. It is mainly divided into virtual component and virtual component management platform design. Among them, virtual component includes virtual component meta-information, maintenance rule set, sensor, effector and so on. Virtual component management platform includes knowledge base, monitor, decision element, actuator and so on. For the data transmission module, the minimum data transfer update algorithm is added in this paper to ensure the minimum data transmission, optimize the network bandwidth, and improve the transmission performance. The experimental results show that the addition of the algorithm can improve the efficiency of cluster virtual machine management. The interface of monitoring module of virtual component management platform is developed, and the internal data of physical machine and virtual machine are obtained, which is convenient for administrator to view and manage. The function of self-maintenance is demonstrated.
