However, in terms of graphical display mechanism there is a difference between the virtual environment and the traditional environment. So how to measure the performance of graphics display in virtualization environment effectively is especially attended.This paper analyzed the virtual display system in theory by models; compares theoretical data and measured data accessed by the virtual machine system performance evaluation; and finally verified the reasonableness of the model.
