承诺人（签名）：年月日摘要而随着网络带宽和硬件能力的不断发展,基于云计算的虚拟化技术已经日趋成熟,用户可以虚拟PC 主机或虚拟应用桌面,将能够以更低的成本获得更好的使用体验。
但这也带来诸多问题,包括终端的快速更新换代带来的扩展性问题、软硬件的维护问题、个人文档的有效保存、信息安全的防范等问题。
为了有效解决所面临的各类问题,本文通过构建面向个人和中小型企业用户,基于电脑、瘦终端、手机和多媒体移动终端的云桌面服务平台,建立应用商店及可扩展应用执行环境,集成云桌面应用服务,打造新一代的电信运营商服务平台。
本文设计的云桌面平台利用XenServer技术,将服务器虚拟化,组成庞大的服务器集群,提供海量的计算能力和灵活的资源调配机制,也大大地提高了平台的安全性和稳定性,确保平台达到国家级运营商平台的要求；利用XenDesktop技术,将虚拟机桌面推送给使用客户,解决了用户端设备局限性的问题,在网络宽带大幅提速的条件下,利用虚拟桌面推送方式可实现任何应用程序的推算服务；利用XenApp技术,将应用的执行环境放在云端,打造SaaS (Software-as-a-service)的服务模式,为用户搭建统一的软件资源平台、应用平台和服务平台。
本文研给出的云桌面平台实现包括门户网站、个人用户和企业用户的管理后台、以及面向运营商的业务管理管理后台和客户资料管理系统。
用户可以通过网站,直接定制和使用云桌面提供的各类应用、内容、和个人主机租用服务,同时也避免了个人终端的升级、维护、软件系统安装、更新等繁琐问题。
用户只需通过个人电脑、手机或其它云终端设备,并通过移动或固定网络就能轻松获取公共计算资源。
本文给出的解决方案,可实现虚拟桌面取代传统电脑。
用户只需通过安装简易的瘦终端,通过网络使用包含操作系统、工具软件、游戏等各类应用服务,并且免去传统电脑硬件故障、电脑病毒、黑客攻击、软硬件升级等繁琐问题。
目前云桌面平台已经在电信内部普及使用,并逐步推广商用。

But this also brings a lot of problems, including the rapid upgrading of the terminal to bring the problem of scalability, hardware and software maintenance problems, the effective preservation of personal documents, information security and other issues. In order to effectively solve the facing all kinds of problems, this paper build for individuals and small business users, based on computer, thin terminals, mobile phones and multimedia mobile terminal desktop cloud service platform, the establishment of the app store and scalable application execution environment, integrated cloud desktop should be with the service, to create a new generation of service platform for telecom operators. Cloud desktop platform based on XenServer technology is designed in this paper, the server virtualization, composed of a large server cluster, providing massive computing power and flexible resource allocation mechanism, but also improve the safety and stability of the platform greatly, ensure that the platform to achieve national operator platform requirements; using XenDesktop technology, virtual machine the desktop pushed to the customer, customer premise equipment to solve the problem of limitations, in a substantial speed broadband network conditions, push mode can realize the calculation service of any application using virtual desktop; using XenApp technology, the application execution environment in the cloud, build SaaS (Software-as-a-service) service model, build software resource platform, unified application platform and service platform for users. In this paper, the research shows the cloud desktop platform to achieve, including portal website, the personal user and enterprise user management background, as well as for the operators of the business management background and customer information management system. Users through the website, directly customize and use desktop cloud provides all kinds of application, content, and individual host rental service, while avoiding the personal terminal upgrades, maintenance, software installation, updates and other complicated problems. Users simply through personal computers, mobile phones or other cloud terminal equipment, and through mobile or fixed network can easily access to public computing resources. This paper gives solutions that can be implemented to replace the traditional computer virtual desktop. Users simply by installing a simple thin terminal. Use contains operating system, tools, software, games and othertypes of application services through the network, and eliminates the traditional computer hardware failure, computer viruses, hacker attacks, software and hardware upgrades and other complicated problems. Currently cloud desktop platform has been widely used in telecommunications, and gradually promote commercial.[keyword]: cloud desktop virtualization technology in cloud computing thin terminal目录1绪论 (1)1.1研究背景： (1)1.2选题意义 (2)2 桌面虚拟化与应用虚拟化简介、实验 (3)2.1什么是服务器虚拟化 (3)2.2什么是桌面虚拟化和应用虚拟化 (3)2.3什么是瘦客服端 (4)3实验环境的构建 (5)3.1拓扑结构介绍 (5)3.2操作系统安装................................................................错误！未定义书签。
