REJUVENATION PROCESSING DEVICE, REJUVENATION PROCESSING SYSTEM, COMPUTER PROGRAM, AND DATA PROCESSING METHOD

摘要

In a rejuvenation processing device (1), at least one host machine (3) is selected as an object to be rejuvenated from among each of the host machines (3). At least one virtual machine (302) is selected from among the virtual machines (302) operating in the host machine (3) which is not selected as an object to be rejuvenated. The operation of the selected virtual machine (302) is stopped, and the virtual machine (302) operating in the host machine (3) selected as the object to be rejuvenated is migrated to the host machine (3) in which the virtual machine (302) operates. The host machine (3) selected as the object to be rejuvenated is rejuvenated. Thereby, it is possible to provide a rejuvenation processing device capable of simultaneously rejuvenating the host machines and the virtual machines necessary to be rejuvenated, while continuously operating the host machines and the virtual machines which are not necessary to be rejuvenated.
