Load Balancing Method for Virtual Machine Resources in Virtual Computing Environment
Chen Yang · Jisuanji gongcheng · 2010
Aiming at the large granularity of Virtual Machine(VM) resources and the great amount of data transferred in the process of migrating,this paper presents a load balancing method based on VM migration.It uses the threshold to predict load tendency of host machine,which ensures that a small transient spike does not trigger needless VM migration.After triggering migration,it uses probability-weighted approach to select the target node,which resolves the problem of accumulation conflicts.Experimental results show that the method can improve the system performance in the case of great imbalance of the host machine load distribution.
