Memory Migration in Virtual Machines
{"Image DocumentName": "Memory Migration in Virtual Machines", "Image ImageDescription": "Three possible approaches. Pre-copy: push memory pages to the new machine and resend the ones that are later modified during the migration process. Stop-and-copy: pause the current virtual machine; migrate memory, and start the new virtual machine. Let the new virtual machine pull in new pages as needed, using demand paging. Clark et.al use a combination of pre-copy and stop-and-copy; claim downtimes of 200ms or less.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
