摘  要

虚拟桌面系统在云计算的背景下应运而少。通过云计算软件来实现桌面的统一管理，为用户提供各种环境下的网络操作系统、数据处理功能和海量存储等资源的共享，让用户轻松地实现生产与管理业务的信息处理。是云计算应用不可或缺的组成部分。

本文以某学校教育虚拟桌面系统系统解决方案为例，研究在由集群服务器构建的私有云环境下，与可以自主计算终端构成的虚拟桌面系统。首先对桌面使用密集型的行业进行了需求分析，提出理想桌面的业务原型，它集成了网络引导、虚拟硬盘、设备驱动等技术的网络数据集中管理存储、操作系统统一分发、统一升级、软件统一安装、远程控制的综合性IT桌面解决方案。集成了VMware优秀的虚拟桌面系统解决方案，能提供最终用户良好的用户体验，并把业务原型转化为功能原型。然后详细介绍了转化功能原型的方法和过程。最后对虚拟桌面系统系统进行测试，对结果进行横向与传统无盘化的瘦客户机及带还原卡的PC进行比较，纵向与国外知名的桌面虚拟化软件对比，验证了本文研究方案的可行性与先进性。

Abstract

Virtual desktop systems in the background of cloud computing should be less. Through cloud computing software to realize the unified management of desktop， to provide users with various environment network operating system， data processing function and mass storage and other resources sharing， so that users can easily achieve the production and management of business information processing. Is an indispensable part of cloud computing applications.

Taking a school education virtual desktop system solution as an example， this paper studies a virtual desktop system which is composed of a private cloud environment constructed by cluster servers and an autonomous computing terminal. Firstly， the demand analysis of desktop use-intensive industry is carried out， and the business prototype of ideal desktop is put forward. It integrates the network data centralized management and storage of network boot， virtual hard disk， device driver and so on， and the unified distribution of operating system. Unified upgrade， software unified installation， remote control of comprehensive IT desktop solutions. Integrated with VMware's excellent virtual desktop system solution for end-user friendly usin User experience and transformation of business prototypes into functional prototypes. Then the method and process of transforming functional prototype are introduced in detail. Finally， the virtual desktop system is tested， and the results are compared with the traditional non-diskless thin client and PC with restore card， and the results are compared with the famous desktop virtualization software in foreign countries. The feasibility and advanced nature of the research scheme are verified.

Keywords: cloud computing; virtual desktop systems; VMware; remote control
