An information processing device (10), including: a memory (13); a processing unit (12) which operates a virtual machine, an operating system which is executed on the virtual machine, and a hypervisor which controls the virtual machine; and a control unit (21) which controls a system including the memory and the processor. The processing unit (12) stops the operating system when detecting an error of the hypervisor,
notifies the control unit of a first memory area used by the hypervisor, stops the hypervisor, changes a memory area used by the hypervisor into a second memory area different from the first memory area notified by the control unit, starts the hypervisor using the second memory area as an available area, starts the operating system, and reads data in the first memory area, and writes the data to a file as a dump file of the hypervisor. |
