Abstract: In this paper,through the analysis of VMware ESX and Xen CPU scheduling algorithm,it is found that scheduling algorithms are based on partition queue model.We proposed to establish a shared queue model to improve the credit algorithm,and then carried on the theoretical analysis and simulation experiments of the model.Based on the simulation results,the performance evaluation of the improved scheduling algorithm was performed.

Key words: Virtualization,Xen,Credit scheduling algorithms,Queueing theory,Sharing queue model
