Research And Implementation Of Desktop Virtualization VDI Based On KVM

At present,the State grid of Sichuan electric power company using your desktop computer PC desktop,with the continuous information construction of State grid power company in Sichuan province,continuous line of business systems,desktop software installed on your PC program and client type and an increasing number,providing the computing and storage capacity has become more.However,the desktop PC desktop information confidentiality,Server resource utilization and high maintenance costs,and strong PC desktop processing power,large local disk storage capacity,especially in the electricity business,few people may install on the operating machine running and work-related software,vulnerable to a Trojan horse or virus attack,impact on the network,data,and infrastructure security.Existing desktop PC security and management on the desktop drawbacks,mainly: 1)Equipment utilization rate is low,many server device is in shutdown state,because the inside of the business system data needs to be maintained,cannot reuse the physical resources,creates a lot of waste of resources.2)Inefficient management,installed because Office computers scattered across a variety of office equipment is scattered,cannot achieve centralized management,computer operating system and application software needs to be installed separately,upgrades,often resulting in Terminal software maintenance management issues.3)Maintenance difficulty big,existing office computer due to work time long,its thermal and hard disk parts General in running half or one years time Hou,compared easy occurred fault,so traditional office computer in voted with one years time Hou hardware fault rate gradually increased,exists high of important data lost risk,while due to software errors loaded misuse,operation problem,often need maintenance or again installation operating system.4)Poor data security,the existing office computer file information is stored in the local disk,a lot of content belongs to valuable data assets and protecting information,office computer with multiple input/output interface,although you can install the desktop management software,illegal copies leaked data remains high risk.Through the study of virtualization and DVI technology,formed by multiple X86 Server Desktop cloud resource pools,cloud provides users virtual desktop based on virtualization.By running on a virtual desktop pool the user required operating system,application software,network connection,using optimized protocols operating system desktop view image or video to the user terminal,can be an existing PC or thin terminals.Through the deployment of the server to process the user input and display on the Terminal.Cloud desktop deployment of pooled resources in a way,flexibility and harmonization of monitoring and controlling server resources,reduce the complexity of operation and maintenance.
