摘要：As a part of workload consolidation in Cloud datacenter, after detecting overloaded hosts, it is required to select the VMs to be migrated such that after migration, the overloaded hosts become normal. Selection of VMs to be migrated is a crucial decision as it affects the performance of both the types of hosts (i.e. the overloaded hosts from which the VMs are selected and the hosts on which the selected VM are placed). This in turn impinges on the performance of overall datacenter. We propose a policy for selection of VMs to be migrated from overloaded hosts based on three criterions. Select VMs in such as way that (i) after migrating the VMs, utilization of overloaded hosts falls below upper threshold value and remain nearest to it (MaxUtil) (ii) the number of VMs remains minimal (MinTotalMigr) and (iii) resultant migration time stays minimum (MinMigrTime). All these three parameters are significant in the process of workload consolidation. Importance of individual parameter over the other is left to individual user�s requirement. In this research, we have proposed a method to optimally select a best VM combination such that all these three parameters are satisfied.
