Abstract
In a virtualized computer system, guest memory pages are mapped to disk blocks that contain identical contents and the mapping is used to improve management processes performed on virtual machines, such as live migration and snapshots. These processes are performed with less data being transferred because the mapping data of those guest memory pages that have identical content stored on disk are transmitted instead of the their contents. As a result, live migration and snapshots can be carried out more quickly. The mapping of the guest memory pages to disk blocks can also be used to optimize other tasks, such as page swaps and memory error corrections.
