Virtual machine (VM) consolidation is one of the strategies implemented to accomplish energy e!ciency in data centres. Data centres take advantage of VM live migration to reduce the energy consumption without application downtime. However, the cost of VM live migration is not considered in some of the VM consolidation approaches. The key focus of this paper is to show how di↵erent workloads can impact the time of VM live migration. We demonstrate through live experiment the link between various workload characteristics and the time of VM live migration. We used the Kernel-based Virtual Machine (KVM) as a hypervisor and SPECjvm2008 benchmark to generate various workloads. Our results show a link between VM migration time and memory size of the VM as well as the speed of the network. We also provide a testing framework to facilitate automated experimentation and benchmarking of VM live migration by other researchers.
