Abstract: The paper suggests that virtual cloud desktop be built by adopting virtualized technology with the distributing server as the the processing center and the thin client as the terminal, which can solve the problems of great cost, high energy consumption and complicated management by using independent PC in computer laboratories. Hence an optimized scheme is proposed for the more applicable virtual cloud desktop in computer laboratory construction resulting from the research of virtual cloud desktop systems.

Key words: cloud desktop; virtualization; computer laboratory construction; thin-client
