Abstract: When executing firmware of a first hypervisor stored in a first memory area, an information processing device stores firmware of a second hypervisor into a second memory area. The information processing device issues, from the first hypervisor, a stopping instruction that instructs a caller of a hypervisor call to stop issuing a new hypervisor call. Herein, let designating information be information that designates a memory area storing firmware of a hypervisor executed by the information processing device. The information processing device rewrites the designating information from a first value that designates the first memory area to a second value that designates the second memory area. The information processing device starts execution of the firmware of the second hypervisor in response to the rewriting of the designating information. The information processing device issues, from the second hypervisor to the caller, a canceling instruction that cancels the stopping instruction.
