Conventional Virtual Machine (VM) migration focuses on transferring a VM's memory and CPU states across host machines. The VM's disk image has to remain accessible to both the source and destination host machines through shared storage during the migration. As a result, conventional virtual machine migration is limited to host machines on the same Local Area Network (LAN) since sharing storage across Wide-Area Network (WAN) is inefficient. As datacenters are being constructed around the globe, the authors envision the need for VM migration across datacenter boundaries. They thus propose a system aiming to achieve efficient VM migration over wide area network.
