This paper analyzes the current situation of computer class experiment and cloud computing virtualization technology in university, and builds a virtual cloud platform integrating various application software and operating systems, and provides various services on demand, using thin client/cloud server mode. It realizes the application software and program compilation of computer classes by means of server model simulation and remote hardware manipulation. In order to solve the conflict of resource occupation in the experiment, the appointment mechanism and the least recent law principle are adopted. This virtual experiment cloud platform realizes education resource integration, reduces the cost of university's input to the experiment, improves the information level of universities, and then promotes the development of education technology in the world.
