This research uses multiple PC with Ethernet built into the PC cluster environment, and then uses the KVM virtualization technique to carry on the establishment virtual computer classroom system. For solving the system developed by the Institute related to the past does not have to revivification, the problem of uneven load the host entity, this research function and LVM snapshot file protocol iSCSI virtual disk to create a shared file system, and developed in this environment an attached balance and quick restore mechanism. Mechanism in the user connection, the user is connected to the Host Server RDP protocol and then get through the KVM virtual machine monitor function control, while not directly obtained through the network connection, so if IT-related courses to be Professor reinstall the system or set up network, the system can achieve the purpose of teaching. Finally, this research will Kunshan University, this system is open to the Department of Information and Communication Ministry of second-year university courses and the Linux operating system, server build technical education divisions of two courses used. In this research, only seven personal computers will be sufficient to supply a class while on-line, and when even after a period of time effective to maintain physical host load balancing.
