International Business Machines Assigned Patent for Method for Efficient Guest Operating System (OS) Migration Over a Network


(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., June 19 -- International Business Machines, Armonk, N.Y., has been assigned a patent (8,468,288) developed by five co-inventors for a "method for efficient guest operating system (OS) migration over a network." The co-inventors are Kevin M. Corry, Austin, Texas, Mark A. Peloquin, Austin, Texas, Steven L. Pratt, Austin, Texas, Karl M. Rister, Austin, Texas, and Andrew M. Theurer, Austin, Texas.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method, data processing system and computer program product enables efficient transfer of a virtual machine from a first data processing system (DPS) to a second DPS using a combination of Transmission Control Protocol (TCP) and Uniform Data Protocol (UDP). A virtual machine migration (VMM) utility identifies all memory pages of the first virtual machine. The VMM utility notifies the second DPS via TCP of the scheduled transfer of the virtual machine. The VMM utility copies and transfers the memory pages of the virtual machine to the second DPS via UDP. When all expected components of the virtual machine are not received by the second DPS and/or memory data is modified within the memory pages during the migration, the VMM utility combines the missing data and the modified data and transfers the final components of the virtual machine using TCP. Execution of the virtual machine resumes on the second DPS." The patent application was filed on Dec. 10, 2009 (12/634,830).
