A system for migrating a virtual machine includes: a first device; and a second device. The first device notifies the second device of failure information indicating that data transported to the second device includes an error originated from the first device, when the error is detected from a storage area in the first device. The second device writes a second identifier, whose value is different from that of a first identifier, into a memory of the second device while associating the second identifier with a second address, the second address being to serve as a copy destination of data indicated by the failure information, wherein the first identifier indicates that data in the second address includes an error originated from the second device, and the second identifier serves as an identifier indicating that data in the second address includes an error originated from the first device.

System, information processing device, and non-transitory medium for storing program for migration of virtual machine

A processor includes: a primary cache memory; an instruction control unit that issues a store request to the primary cache memory; a pipeline processing unit that, upon receiving the store request, writes data to the primary cache memory; a buffer unit that obtains an address output to the primary cache memory from the pipeline processing unit during an output period of the store request regarding certain data to hold the obtained address in an entry, and when the output period ends, issues a write-back request for writing the data indicated by the address held in the entry to a memory; and a secondary cache memory that, upon receiving the write-back request from the buffer unit, writes the data of the primary cache memory to the memory, the certain data is quickly written back to the memory from the primary cache memory.
