PROBLEM TO BE SOLVED: To reduce performance deterioration after virtual machine migration.SOLUTION: A migration processing apparatus includes: a memory access information storage part; a necessary memory data identifying information storage part; and a migration control part which investigates memory access of a virtual machine, stores a memory access history in the memory access information storage part, creates necessary memory data identifying information serving as information for identifying necessary memory data, which is memory data which the virtual machine accesses immediately after start-up of the virtual machine on the basis of the memory access history, stores it in the necessary memory data identification information storage part, identifies necessary memory data on the basis of a memory access state of the virtual machine at a current point of time and the necessary memory data identification information, migrates to a migration destination, and migrates, after the necessary memory data is migrated, the virtual machine to the migration destination. |
