Lazy Restore Using Memory Paging

by Dushyant Behl for Xen Project

VM save/restore functionality is one of the most commonly used in Clouds and Virtualization platforms. The current implementation of VM save/restore in Xen results in loading the entire memory image of the VM from the save file which in turns slows down the entire process. I plan to improve this process by introducing the concept of Lazy restore and using memory paging.
