ORDERED MEMORY PAGES TRANSMISSION IN VIRTUAL MACHINE LIVE MIGRATION

摘要

Systems and methods for virtual machine live migration. An example method may comprise: identifying, by a first computer system executing a virtual machine undergoing live migration to a second computer system, a plurality of stable memory pages comprised by an execution state of the virtual machine, wherein the plurality of stable memory pages comprises memory pages that have not been modified within a defined period of time; transmitting the plurality of stable memory pages to the second computer system; determining that an amount of memory comprised by a plurality of unstable memory pages is below a threshold value, wherein the plurality of unstable memory pages comprises memory pages that have been modified within the defined period of time; and transmitting the plurality of unstable memory pages to the second computer system.
