Application Research Of Desktop Virtualization Technology On The Colleges Network Experimental Platform

The significance of this study lies in the Great Wall college network experimental platform successful transformation of desktop virtualization, improve the management mode of network experimental platform, make teaching more efficient and convenient, more convenient management, which for other colleges and universities and small school network environment and upgrading have certain reference function. In terms of academic value of the paper lies in the use of KVM, QEMU, Libvirt and SPICE and other innovative technologies, provides a desktop virtualization architecture of open source solutions.The present situation is topic in today's society, the rapid development of information technology, it brings great convenience to the human work at the same time, the computer terminal(PC) increases rapidly, increasing pressure also makes the operation and maintenance work more. This involves network security, system change and optimization work, many data backup and so on. The computer room, as the focus on the use of location, with the computer terminal number, long service time, high calorific value, high energy consumption, easy computer virus infection, system maintenance difficult problem diverse operation.The overall design idea of subject to the above problems are solved by using desktop virtualization technology. Virtualization technology has been developed rapidly in recent years, from the desktop to the backend server, from the storage system to the Internet, the field of virtualization can involve more and more widely. Desktop virtualization technology as an important part of virtualization technology is also in rapid development, and to solve the above problems, provides a feasible solution. Desktop virtualization, centralized management, decentralized processing mode display, through virtualization technology, the operation process of the computer to the server through the network transmission, the results will be displayed to the terminal display. As in the room, through the desktop virtualization technology, you can put many distributed computer terminal unified management, to the great help for computer maintenance work.The virtualization technology, first from two aspects at home and abroad introduces the current development situation of virtualization technology, and then deeply introduces the basic theoretical knowledge of virtualization technology, desktop virtualization technology; In order to realize the problem of desktop virtualization, the middle part of the optimization design of the desktop virtualization system architecture based on KVM. The desktop display protocol for the spice protocol, focuses on the design the Desktop Virtualization Server, middleware and desktop client three parts, the design including KVM kernel level of server virtualization, virtual simulation of QEMU PC, complete the desktop display spice server, used to the virtual environment for management of host agent and used to provide the implementation details of the information of the virtual machine guest agent and other functional modules. The results of the study is to achieve a system architecture of desktop virtualization, for the further implementation of desktop virtualization to lay the foundation.This paper according to the part of the room to the the Great Wall school implementation of desktop virtualization is discussed. The virtual desktop computer terminal of the Great Wall college, part of the room from the perspective of practical application. According to the Great Wall college computer room construction demand, discusses the construction of desktop virtualization hardware solutions and desktop virtualization system software implementation scheme, and with the traditional dispersion physical machine from the time of system arrangement and system replacement time and system updates, etc. were compared, so as to more clearly show desktop virtualization technology experiment platform for the network to provide technical support, greatly convenient in network experimental platform of management and system deployment, and in response to the national call for energy saving, makes the contribution for the green campus.Issue the final result is of great wall, part of the room realized based on KVM desktop virtualization, and has good use effect, basically solved the traditional room can spread a single physical many management and operation drawbacks. Desktop virtualization is a cloud computing, the field of higher education in the future, cloud computing will become increasingly important to provide technical support for the reform and development of teaching.
