摘要:
In an information processing apparatus, a control unit includes a first clock device for providing the time of day. A physical domain includes a second clock device, and implements a logical domain that functions as a virtual information processing apparatus. The control unit controls a first time-of-day difference between the time of day of the first clock device and that of the second clock device. The physical domain controls a second time-of-day difference between the time of day of the second clock device and that of the logical domain. In the information processing apparatus, the time of day on the logical domain is controlled based on the first and second time-of-day differences.
摘要:
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.
摘要:
When executing (S1) firmware of a first hypervisor (1a) stored in a first memory area, an information processing device stores (S2) firmware of a second hypervisor (1b) into a second memory area. The information processing device issues (S3), from the first hypervisor (1a), a stopping instruction that instructs a caller of a hypervisor call to stop issuing a new hypervisor call.. The information processing device rewrites (S4) designating information, that designates a memory area storing firmware of a hypervisor executed by the information processing device, 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 (S5), from the second hypervisor to the caller, a canceling instruction that cancels the stopping instruction.

摘要:
An information processing apparatus (10, 20) that mounts a first and second system boards (SB#0, SB#1) includes a virtualization control unit (13, 21) that controls a virtual machine for virtualizing hardware resources. The SB#0 includes a memory (14c, 22) that stores a command line (14d, 22a), resource information (14f, 22d), and management information (14e, 22c). The SB#1 includes a memory (15c, 32) that stores a command line (15d, 32a) and resource information (15e, 32b). The command line is executed by the virtualization control unit (13, 21). The resource information (14f, 15e, 22d, 32d) is data used by each system board (SB#0, SB#1) from among data used when the virtualization control unit (13, 21) operates. The management information (14e, 22c) is data commonly shared by each system board (SB#0, SB#1) and used by the virtualization control unit (13, 21). A command line (14d, 15d, 22a, 32a) and resource information (14f, 15e, 22d, 32d) are used when the virtualization control unit (13, 21) operates and information on the hardware resources (14f, 15e, 22d, 32d) included in the corresponding SB (SB#0, SB#1). Each SB (SB#0, SB#1) executes the command line (14d, 15d, 22a, 32a) and refers to the information stored in the memory (14c, 15c, 22, 32) in SBs (SB#0, SB#1).
