An Evaluation of Virtual Machine Placement by Using Live Migration

Virtualisation technology which can decrease the number of physical machines to use the resources effectively has become a research trend. Several methods of Live Migration (LM) for Virtual Machine (VM) Placement have been proposed. However, existing LM methods do not well take into account, such as transfer time and Random-Access Memory (RAM) usage of each VM. Considering this situation, we have already proposed a method of LM in case of “on-premise” system structure to balance the load of each physical server considering total RAM usage by VMs in a physical server and the bit transfer time proportional to Round-Trip Delay Time (RTT). Also, through a preliminary evaluation, we have shown that our method has a possibility to make the total processing time shorter. Based on this result, this paper revisits the proposal, evaluates it by giving additional conditions and shows its effectiveness.
