【摘要】：在云计算环境下,随着企业对主机服务器数量和质量需求的不断提升,对于高配置主机的单一利用,极大浪费了硬件资源,造成企业开发成本增加,于是利用虚拟化技术实现物理资源的逻辑划分来提高物理资源利用率已经成为一种发展趋势,但是对于虚拟化产生的数量庞大的虚拟机管理难度也在不断增加。针对上述问题,本文设计并实现了基于SAN环境的虚拟资源管理系统(Virtual Resource Management System, VRMS),该系统利用虚拟化技术实现了物理主机的虚拟化,以充分利用物理机资源,并针对虚拟机实现一系列的管理操作,保证虚拟机的运行安全。主要工作如下：(1)设计VRMS虚拟资源管理系统整体结构,通过分析VRMS要达到的主要功能将其抽象成模块,并按照模块设计实现。(2)设计故障检测策略,及时判断主机和虚拟机的健康状态。对于发生故障的主机,快速并且均衡迁移其上面的虚拟机到其他正常主机,以保证虚拟机上运行的服务能够正常运行,最大程度地减小因机器故障带来的影响。(3)基于全量备份、增量备份和差异备份三种技术,实现对于虚拟机数据的备份和还原功能,通过交叉配合使用不同的备份方式,充分发挥各种备份技术的优点,用户根据自己对于虚拟机的状态保存设定进行及时备份,当虚拟机不慎损毁时,利用备份文件还原到以前某个状态,避免重新安装的时间和人力消耗。综上所述,本论文设计并实现了VRMS虚拟资源管理系统,通过测试与验证,该系统能够实现物理主机的虚拟化功能,充分使用物理硬件资源,同时实现了对于虚拟机的管理操作,方便用户控制虚拟机的运行状态,保障虚拟机的安全。
[Abstract]:In the cloud computing environment, with the increasing demand for the quantity and quality of the host server, the single utilization of the high configuration host greatly wastes the hardware resources and increases the development cost of the enterprise. Therefore, using virtualization technology to achieve logical partition of physical resources to improve the utilization of physical resources has become a trend, but for virtualization of a large number of virtual machine management difficulties are also increasing. In view of the above problems, this paper designs and implements a virtual resource management system based on San environment, Virtual Resource Management system (VRMSM), which realizes the virtualization of physical hosts by using virtualization technology to make full use of the resources of physical computers. A series of management operations are implemented for the virtual machine to ensure the running security of the virtual machine. The main work is as follows: 1) designing the whole structure of VRMS virtual resource management system, abstracting it into modules by analyzing the main functions of VRMS, and designing fault detection strategy according to module design. Judge the health status of host and virtual machine in time. For malfunctioning hosts, quickly and equitably migrate the virtual machines above them to other normal hosts to ensure that the services running on the virtual machines can run normally and minimize the impact caused by machine failures. Incremental backup and differential backup realize the backup and restore function of virtual machine data, and make full use of the advantages of all kinds of backup technology by cross-matching different backup methods. When the virtual machine is damaged, the backup file is used to restore to a previous state to avoid the time and labor consumption of reinstallation. To sum up, this paper designs and implements VRMS virtual resource management system. Through testing and verification, the system can realize the virtualization function of physical host, make full use of physical hardware resources, and realize the management operation of virtual machine. It is convenient for users to control the running state of virtual machine and ensure the security of virtual machine.
