Abstract: Based on the graphic display characteristics in virtual environment, the paper sets up a virtual display performance evaluating system in paravirtualized environment and acquires the related performance parameter by tracing. It makes a theoretical analysis of the factors influencing the display capability by queue-modeling and brings out the performance bottlenecks in different situations by making a comparison with the actual experimental data.

Key words: virtual machine, paravirtulized, performance evaluation, modeling, queueing theory
