摘要：
An effective and efficient VM scheduling algorithm can improve utilization rate of physical servers and lower energy cost. Current VM allocation algorithms focus on the requirement of CPU, Memory and network bandwidth which trying to allocate VM into physical servers in a low cost way. However, when the jobs are finished, related VMs quit from the system, which leads to the decline of resource utilization and the increasing of transmission delay. This paper studied the network-aware resource reconfiguration problem and proposed a network-aware VM re-scheduling algorithm based on VM live migration. This algorithm focuses on improving communication ability among VMs to promote the overall performance in a way of low migration cost and little extra physical used. Two test beds are deployed in a real environment to examine the effectiveness of the VM reconfiguration algorithm. We compared the result of before and after using our algorithm with different consolidation algorithms based on the real workload data and simulation. The results show that our algorithm considerably reducing the amount of high-delay jobs and improving the communication ability among VMs only with very small cost. ©, 2015, Science Press.
