Abstract

In Infrastructure-as-a-Service datacenters, the placement of Virtual Machines (VMs) on physical hosts are dynamically optimized in response to resource utilization of the hosts. However, existing live migration techniques, used to move VMs between hosts, need to involve large data transfer and prevents dynamic consolidation systems from optimizing VM placements efficiently. In this paper, we propose a technique called "memory reusing" that reduces the amount of transferred memory of live migration. When a VM migrates to another host, the memory image of the VM is kept in the source host. When the VM migrates back to the original host later, the kept memory image will be "reused", i.e. memory pages which are identical to the kept pages will not be transferred. We implemented a system named MiyakoDori that uses memory reusing in live migrations. Evaluations show that MiyakoDori significantly reduced the amount of transferred memory of live migrations and reduced 87% of unnecessary energy consumption when integrated with our dynamic VM consolidation system.
