An example method may comprise: reading, by a hypervisor running on a first computer system, from a memory mapped into an address space of a virtual machine undergoing live migration from the first computer system to a second computer system, a data structure comprising a plurality of records, each record mapping an address of a memory page to an identifier of a virtual disk frame storing contents of the memory page; reading a plurality of page modification flags, each page modification flag indicating that contents of a corresponding memory page differ from contents of a virtual disk frame referenced by the data structure; responsive to determining that a memory page is referenced by the data structure and that a page modification flag corresponding to the memory page is set, transmitting the memory page to the second computer system; and responsive to determining that a memory page is not referenced by the data structure, transmitting the memory page to the second computer system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reducing redundant network transmissions in virtual machine live migration","description":"Systems and methods for reducing redundant network transmissions in virtual machine live migration.
