Analyzing Energy Consumption during VM Live Migration

As energy consumption increased in data centers, various efforts have been made towards higher energy efficiency. Energy consumption is the main reason of high cost incurred by data centers in required Quality of Service constraints. In particular, Live Virtual Machine migration in data centers has great potential to decrease energy consumption up to certain level of usage. One of the mechanisms to achieve energy efficiency is to manage the migration time parameter of VM Live migration with appropriate network bandwidth in communication aware connected data centers. In spite of this, VM size and network bandwidth have a great impact on energy consumption of sub systems during VM Live migration. To follow this study, in this paper we analyzed the impact of migration time on energy consumption of sub systems during guest VM Live migration. We used Kernel-based Virtual Machine (KVM) hypervisor and Virt Manager to perform VM Live migration on Ubuntu 14.04 Linux machines in various conditions.
