Exploiting Data Deduplication to Accelerate Live Virtual Machine Migration

Free registration required

Executive Summary

As one of the key characteristics of virtualization, live Virtual Machine (VM) migration provides great benefits for load balancing, power management, fault tolerance and other system maintenance issues in modern clusters and data centers. Although Pre-Copy is a widespread used migration algorithm, it does transfer a lot of duplicated memory image data from source to destination, which results in longer migration time and downtime. This paper proposes a novel VM migration approach, named Migration with Data Deduplication (MDD), which introduces data deduplication into migration.
