Due to the high construction cost of virtual laboratories in its initial stage, traditional laboratories are updated to function as clients from the perspective of technology. The design of client virtualization is proposed in order to reduce the expenses of clients' hardware. Centered on servers resources, laboratory optimized model is established by integrating resources, namely hardware and software resources. Based on the teacher resources and characteristics of specialized teaching, the use of laboratories can be reduced as much as possible by optimizing design of laboratories resources under the limitation of course scheduling system. More laboratories will be shared by using virtual laboratories based on desktop cloud, which has weakened the function of specialized labs and reduced the redundant construction as well as the maintenance cost of labs.
