Collegiate Programming Examination(CPE) has been launched in 2010, and initially organized by National Chiao Tung University and National Sun Yat-sen University. This work includes implements to integrate a variety of technologies in the trial of a number of software, and contributed to such a large-scale inter-collegial joint examination of computer operation. We propose a convenient and rapid solution for deployment of examination classroom environment to reduce the burden of administrators of the computer classrooms. There are 33 universities joining CPE held in May 2012. We have developed the mechanism in order to manage thousands of virtual machine. And this mechanism could be contributed to the management of cloud computing service.
