摘　　要：基于虚拟化平台搭建语音教室中的一些关键技术问题及其解决方法,包括采用不同的设备重定向机制将插在客户端或服务器上的USB设备重定向到运行在服务器上的特定虚拟桌面;利用不同的协议实现桌面、音频在语音教学环境中的传输;在虚拟化平台中结合传统的无盘技术实现可定制虚拟桌面的快速发布,以及如何在平台中实现用户统一认证以及自动登录连接自己的虚拟桌面。This paper introduces some key technical issues and solutions to deploy a voice classroom environment by a kvm-based desktop virtualization platform.Different device redirection mechanism can be used to map the USB device on client or server into the special virtual desktop running in the backend.Different protocols can be used to transport desktop or audio among virtual desktops for students and that for teacher in the teaching environment.By integrating the diskless technology into the virtualization platform,it is possible to publish customizable virtual desktop.In addition,this paper also shows how user can automatically log on and connect to his/her own virtual desktop with concrete authentication mechanism.
