Abstract: With the continuous development of cloud computing,the virtual desktop infrastructure(VDI) solution is becoming more and more mature.VDI is established on the basis of the virtualization technology,break through the limit of time and space,effectively solve the problems in the process of using traditional personal computer,and is the mainstream in current desktop cloud solution architecture and deployment.In this paper,making full use of the advantages of VDI,combining with the epidemic KVM virtualization technology,virtual desktop resolution architecture was discussed and made actual deployment,and the optimization platform was detailed designed.Finally we did the test and recorded performance results,which verify the correctness and availability of the system.The results show that the VDI brings many conveniences for mobile computing,management and reducing operational costs of modern computer room,and provides real guidance for colleges deploying virtualization platform.
