INFORMATION PROCESSING DEVICE INCLUDING MEMORY DUMP FUNCTION, MEMORY DUMP METHOD, AND A COMPUTER READABLE RECORDING MEDIUM FOR RECORDING MEMORY DUMP PROGRAM

摘要

The present invention has an assignment which collects memory dump for investigating causes by rapidly resuming tasks when defects which are necessary to be operated again are sensed. When errors of a hypervisor or problems of an operating system are sensed, a first memory area used by the kernel of the operating system or the hypervisor is notified to firmware, the hypervisor and the operating system are stopped, the memory area used by the kernel of the operating system or the hypervisor is converted a second memory area which is different from the first memory area, and restarts the work by operating the hypervisor and the operating system. Data is recorded in a file by reading the data of the first memory area.;COPYRIGHT KIPO 2014;[Reference numerals] (201-1) Control domain #0; (201-2) Domain #1; (201-3) Domain #2; (201-4) Dump domain #3; (203-1,203-2,203-3,203-4) Memory; (204-1,204-2,204-3,204-4) Disk; (311) Firmware; (351) Hypervisor; (401-1) OS of control domain; (401-2) OS of domain 1; (401-3) OS of domain 2; (401-4) OS of dump domain
