It allows cloud administrators to control and manage the computing resources flexibly in the cloud. Live migration offers two policies: 1) pre-copy and 2) post-copy. The differences in the policies result in different performance characteristics. The trade-off stemming from the differences in the policies must be taken into consideration when a virtual machine is to be moved from one physical machine to another. In this paper, we summarize our previous results of the performance comparison of Xen pre-copy, KVM pre-copy and KVM post-copy, and show a simple model that estimates the migration time of Xen pre-copy and KVM post-copy.Live migration of virtual machines (VMs) is a promising technique for cloud management.
