AbstractWith the development of virtualization technology and computer hardware,moreand more enterprises,governments,schools and other institutions have begun to applydesktop virtualization products to improve office efficiency and reduce operatingcosts.The core idea of desktop virtualization system is "centralized management anddistribution display".On the one hand,it provides virtual desktop environment so thatusers can access their desktop environment anytime and anywhere for work orlearning,and provides flexible and secure desktop experience;the virtual desktop tothe system background for centralized management,greatly reducing the computeroperation cost of enterprises.The traditional desktop virtualization technologyarchitecture is VDI (Virtual Desktop Infrastructure)architecture,characterized by"centralized storage,centralized computing",its characteristics determine that usersmust pass through the network to access their own desktop,and VDI architectureproducts have high requirements for network bandwidth and server computing andstorage performance.To overcome the disadvantages of high server input cost,highnetwork dependence,centralized risk,and poor peripheral device support under theVDI architecture,Intel took the lead in proposing a new IDV (Intelligent DesktopVirtualization)architecture,This is a novel idea of technology,It uses the"distributionoperation,centralized storage"way to meet the needs of users,The server isresponsible for managing and transmitting virtual machine mirrors,The terminal isresponsible for running the virtual desktop,This greatly reduces the computationalpressure on the server and reduces the bandwidth requirements,It also fundamentallyimproves the user experience of the virtual desktop.This paper will design anddevelop a desktop virtualization system based on KVM and IDV architecture forteaching experiment scenarios,and focus on the design and implementation of thedesktop virtualization Linux client.This paper realizes the configuration andmanagement of virtual desktop and various virtual resources through LibvirtAPI;builds mirror resource storage pool based on NFS,Ceph and local storage scheme;and builds VXLAN Tunnel for the communication scheme of virtual desktop acrossphysical network based on Openv Switch.At the end of this paper,the client tests andanalyzes the running effect and performance,and adopts the feasible optimizationscheme to improve the user's desktop experience.
