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

摘要

Disclosed is a rejuvenation processing device (1) wherein at least one host machine (3) is selected as an object to be rejuvenated from among the respective host machines (3). At least one virtual machine (302) is selected from among virtual machines (302) operating in host machines (3) which have not been selected as the object to be rejuvenated. The operation of the selected virtual machine (302) is stopped, and a 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) had been operating. The host machine (3) selected as the object to be rejuvenated is rejuvenated. As a result, a rejuvenation processing device capable of simultaneously rejuvenating host machines and virtual machines which require rejuvenation while continuously operating host machines and virtual machines which require no rejuvenation can be provided.
