H3C云桌面解决方案产品概述H3C Cloud Desktop是我司自行研发的云桌面产品，旨在为最终用户提供虚拟云桌面。
桌面虚拟化即VDI(Virtual Desktop Infrastructure)是一种基于服务器的计算模型，其利用服务器虚拟化技术，并结合传统的瘦客户端技术，将桌面组件（包括应用、操作系统和用户设置等）转移到数据中心进行集中管理，通过桌面连接协议生成独立的桌面操作系统，发送给本地终端设备，供用户在本地终端上使用。
管理员可以通过虚拟桌面管理平台将所有虚拟化的桌面在数据中心进行托管，并进行统一管理、集中控制。
用户可以在使用虚拟化桌面时获得PC机类似的使用体验，可以利用终端设备、PC或者其他任何可以连接到网络的设备通过应用程序或者浏览器访问驻留在服务器端的桌面操作系统。

目录1 技术产生背景 (1)2 技术原理 (1)2.1 完整克隆 (1)2.2 快速克隆 (1)3 Sysprep (2)1 技术产生背景在云桌面的部署和维护过程中，发布新的桌面是一项常用操作。
云桌面数量大，发布50个甚至更多桌面时，不可能让管理员安装50个桌面。
云桌面发布技术就是一项帮助管理员快速、准确发布桌面的技术。
2 技术原理云桌面发布的第一步，制作虚拟机模板（也可以将虚拟机转化成模板）。
后续所有的虚拟桌面都基于模板批量发布。
批量发布桌面的技术称为克隆技术，即根据原始虚拟机复制一个或多个桌面。
克隆出来的桌面拥有与原始虚拟机的操作系统、应用系统和数据均完全相同；但会生成新的虚拟网卡MAC地址和UUID 地址，以保证所有克隆出来的桌面不会产生网络冲突。
H3Cloud 云桌面支持两种克隆技术，完整克隆和快速克隆。
2.1 完整克隆完整克隆方式下，克隆的桌面与原始虚拟机是两个完全独立的实体。
其特点如下：●完整克隆的桌面可以脱离原始虚拟机独立存在，模板的关闭、修改、删除都不影响桌面的运行。
●完整克隆需要对原始虚拟机进行完整拷贝，耗时较长。
●完整克隆后的每一个桌面占用与原始虚拟机相同的磁盘空间。
桌面数量大时，消耗大量存储空间。
完整克隆消耗的IOPS与快速克隆是一样的。
2.2 快速克隆快速克隆也称为链接克隆（Linked Clone）。
第一次进行快速克隆时，会生成一个基础镜像文件，同时生成一个增量文件。
增量文件用于记录快速克隆出来的桌面上所有的变更，而基础镜像文件是始终保持不变的。
增量文件始终链接到基础镜像文件上，与基础镜像文件共同组成新桌面的镜像文件，如下图所示。
