Abstract: By contraposing the disadvantages of traditional restore card management in university laboratories，this paper introduced a set of cloud desktop solutions implemented in the professional laboratory of Jianghan University，and the architecture，advantages，and disadvantages of VDI and VOI were analyzed. The solutions merged architectures of VDI and VOI to supply two kinds of clouddesktop for different experimental courses，in the condition of one set of hardware and software systems. This paper summarized some problems that emerged in practice and proposed optimization methods.
