Abstract

A disclosed computer system having a virtual computer management mechanism realizing a virtual computer includes a user virtual computer that communicates with a device via a virtual computer for a device driver under a control of the virtual computer management mechanism, an input receiving unit that receives a signal of an input operation from the device, a reset level determination unit that determines a reset level based on the received signal of the input operation, a reset target specifying unit that specifies a virtual computer to be a target of a reset process based on the determined reset level, and a reset signal transmission unit that transmits a reset signal to perform the reset process on the specified virtual computer.

Claims

1. A computer system having a virtual computer management mechanism realizing a virtual computer, the computer system comprising:

a user virtual computer that communicates with a device via a virtual computer for a device driver under a control of the virtual computer management mechanism;

an input receiving unit that receives a signal of an input operation from the device;

a reset level determination unit that determines a reset level based on the received signal of the input operation;

a reset target specifying unit that specifies a virtual computer to be a target of a reset process based on the determined reset level; and

a reset signal transmission unit that transmits a reset signal to perform the reset process on the specified virtual computer.

2. The computer system according to claim 1, further comprising:

an operation target specifying unit that specifies the user virtual computer to be an operation target of the received signal of the input operation; and

a reset management information storage unit that stores reset management information including identification information of the virtual computer to be the target of the reset process, the virtual computer corresponding to the user virtual computer to be an operation target and the reset level,

wherein for the user virtual computer specified by the operation target specifying unit, the reset target specifying unit refers to the reset management information stored in the reset management information storage unit, and obtains identification information of the virtual computer from the reset management information, the virtual computer corresponding to the reset level determined by the reset level determination unit, so that the reset target specifying unit specifies the virtual computer indicated by the obtained identification information as the virtual computer to be the target of the reset process.

3. A non-transitory computer-readable recording medium comprising a program to cause a computer of a computer system having a virtual computer management mechanism realizing a virtual computer to execute a method comprising:

operating a user virtual computer communicating with a device via a virtual computer for a device driver under a control of the virtual computer management mechanism;

receiving a signal of an input operation from the device;

determining a reset level based on the received signal of the input operation;

specifying a virtual computer to be a target of a reset process based on the determined reset level; and

transmitting a reset signal to perform the reset process on the specified virtual computer.
