【摘要】：随着信息产业和互联网技术的不断飞速发展，信息数据随之成爆炸性的增长，数据中心也变得日益重要和繁杂，从而使得管理工作面临巨大的挑战。在信息负载不断增大的条件下，如何对数据中心的资源进行整合以提高数据中心的能效、资源利用率和降低总体运行成本已成为企业构建和管理数据中心时所需要考量的最主要因素。虚拟化技术便是解决上述问题的最有效途径。本文通过对虚拟化一些关键技术的研究，进而实现服务器虚拟化和桌面虚拟化的原型系统。其中服务器虚拟化平台由虚拟化服务器和远程管理平台两部分组成，虚拟化服务器基于开源Xen虚拟化实现各种虚拟机操作功能，不同操作系统的虚拟机都可部署在其上，并通过SELinux实现虚拟机与虚拟机、虚拟机与宿主机之间的相互隔离，从而实现服务器虚拟化平台的安全保障，而远程管理平台提供对虚拟化服务器的远程管理；桌面虚拟化平台通过远程交付协议实现认证用户与服务器的远程桌面交付，，只有通过严格的身份认证和授权控制的用户才能从虚拟服务器端获取自己的桌面图像信息。本文最后还通过虚拟化技术在某加油站系统中的应用说明了服务器虚拟化平台和桌面虚拟化平台的重要切实作用。
[Abstract]:With the rapid development of information industry and Internet technology, information data has become an explosive growth, data center has become increasingly important and complex, which makes the management work facing a huge challenge. How to integrate the resources of the data center in order to improve the energy efficiency of the data center under the condition of increasing information load, Resource utilization and reducing total operating cost have become the most important factors for enterprises to construct and manage data centers. Virtualization is the most effective way to solve these problems. Through the research of some key technologies of virtualization, this paper implements the prototype system of server virtualization and desktop virtualization. The server virtualization platform consists of two parts: the virtualization server and the remote management platform. Based on open source Xen virtualization, the virtualization server implements various virtual machine operation functions, and the virtual machines of different operating systems can be deployed on it. Through SELinux, the virtual machine and virtual machine, virtual machine and host are isolated from each other, so as to realize the security of the server virtualization platform, while the remote management platform provides remote management of the virtualized server. Desktop virtualization platform implements remote desktop delivery of authenticated users and servers through remote delivery protocol. Only users who are strictly authenticated and authorized to control can obtain their desktop image information from the virtual server. Finally, through the application of virtualization technology in a gas station system, the paper illustrates the important practical role of server virtualization platform and desktop virtualization platform.
