Decreasing live virtual machine migration down-time using a memory page selection based on memory change PDF

Seamless migration of Virtual Machines (VMs) will guarantee the Service Level Agreements during the live data center migration which is an important step for allocation and management of Information and Communication Technology (ICT) infrastructures and resources across the globe. At our knowledge, only simplistic models have been used to describe the governing process of memory migration. In this paper, first, we formulate a mathematical model for virtual machine memory transfer. Then, we show the limitations of such a transfer. Finally, we introduce and evaluate a more efficient method for memory transfer.
