Abstract

An information processing device connected to a power unit includes: a memory; and a processor coupled to the memory and configured to execute a process. The process includes: obtaining information indicating a running state of a virtual machine mounted in the information processing device upon receipt of a notification that a power failure has occurred, and to store the obtained information in the memory; stopping a currently running virtual machine upon receipt of the notification that the power failure has occurred, and to thereafter stop a power supply to hardware within the information processing device; and activating the virtual machine on the basis of information stored in the memory when the power supply to the information processing device is started.

Claims

1. An information processing device connected to a power unit, the information processing device comprising:

a memory; and

a processor coupled to the memory and configured to executes a process comprising;

obtaining information indicating a running state of a virtual machine mounted in the information processing device upon receipt of a notification that a power failure has occurred, and to store the obtained information in the memory;

stopping a currently running virtual machine upon receipt of the notification that the power failure has occurred, and to thereafter stop a power supply to hardware within the information processing device; and

activating the virtual machine on the basis of information stored in the memory when the power supply to the information processing device is started.

2. The information processing device according to claim 1, wherein

the processor stores, in the memory, information about the running state of the virtual machine before the power failure, information about a running state of hardware within the information processing device before the power failure, and information about the power failure.

3. The information processing device according to claim 2, further comprising

the processor configured to activate the hardware within the information processing device on the basis of the information stored in the memory.

4. The information processing device according to claim 1, wherein

the processor collectively stops currently running virtual machines while the power unit is supplying power, when a power failure has occurred.

5. A virtual machine control method, comprising:

obtaining information indicating a running state of a virtual machine mounted in an information processing device upon receipt of a notification that a power failure has occurred, and storing the obtained information in a memory;

stopping a currently running virtual machine upon receipt of the notification that the power failure has occurred, and thereafter stopping a power supply to hardware within the information processing device; and

activating the virtual machine on the basis of the information stored in the memory when the power supply to the information processing device is started.

6. The virtual machine control method according to claim 5, wherein

the memory holds information about a running state of the virtual machine before the power failure, information about a running state of the hardware within the information processing device, and information about the power failure.

7. The virtual machine control method according to claim 6, wherein

the hardware within the information processing device is activated on the basis of the information held in the memory.

8. The virtual machine control method according to claim 5, wherein

currently running virtual machines are collectively stopped while the power unit is supplying power when a power failure has occurred.

9. A non-transitory computer-readable recording medium having stored therein a virtual machine control program for causing a computer to execute a virtual machine control process comprising:

obtaining information indicating a running state of a virtual machine mounted in an information processing device upon receipt of a notification that a power failure has occurred, and storing the obtained information in a memory;

stopping a currently running virtual machine upon receipt of the notification that the power failure has occurred, and thereafter stopping a power supply to hardware within the information processing device; and

activating the virtual machine on the basis of the information stored in the memory when the power supply to the information processing device is started.

10. The non-transitory computer-readable recording medium according to claim 9, the process further comprising

causing the memory to hold information about a running state of the virtual machine before the power failure, information about a running state of the hardware within the information processing device, and information about the power failure.

11. The non-transitory computer-readable recording medium according to claim 10, the process further comprising

activating the virtual machine on the basis of the information stored in the memory when the power supply to the information processing device is started.

12. The non-transitory computer-readable recording medium according to claim 9, wherein

currently running virtual machines are collectively stopped while the power unit is supplying power when a power failure has occurred.
