Abstract

A virtual machine is efficiently constructed, and a constructing time is reduced. Other than a target virtual machine which is a target for setting parameters, a setting purpose virtual machine is provided, and without starting the target virtual machine, a host side virtual machine setting unit of a host obtains a target virtual machine setting parameter file, and makes a storage area for setting parameters of the target virtual machine (a target virtual machine data) accessible from the setting purpose virtual machine, and a guest side virtual machine setting unit sets the parameters of the target virtual machine without starting the target virtual machine by obtaining the target virtual machine setting parameter file from the host side virtual machine setting unit, and writing the setting parameters in the storage area for setting the parameters of the target virtual machine (the target virtual machine data) which has been made accessible.

Claims

1. An information processing apparatus setting a parameter of a virtual machine comprising:

a storage device storing a setting parameter to be set for a target virtual machine which is a target for setting the parameter and having a storage area for setting the parameter of the target virtual machine;

a host having a host OS (Operating System) and a host side virtual machine setting unit which operates on the host OS; and

;

a setting purpose virtual machine, being a virtual machine different from the target virtual machine, having a guest OS and a guest side virtual machine setting unit which operates on the guest OS,

wherein without starting the target virtual machine,

the host side virtual machine setting unit of the host obtains the setting parameter from the storage device, and makes the storage area for setting the parameter of the target virtual machine accessible from the setting purpose virtual machine, and

the guest side virtual machine setting unit of the setting purpose virtual machine obtains the setting parameter from the host side virtual machine setting unit of the host, writes the setting parameter in the storage area for setting the parameter of the target virtual machine which has been made accessible by the host side virtual machine setting unit of the host, and sets the parameter of the target virtual machine.

2. The information processing apparatus of claim 1,

wherein the storage device stores a script in which the setting parameter is written,

wherein the guest side virtual machine setting unit of the setting purpose virtual machine obtains the script from the host side virtual machine setting unit of the host, executes the script, and writes the setting parameter in the storage area for setting the parameter of the target virtual machine.

3. The information processing apparatus of claim 1 further comprising:

a virtual machine copying unit for copying the virtual machine;

wherein the storage device stores a setting parameter to be set for a copied target virtual machine copied by the virtual machine copying unit and has a storage area for setting the parameter of the copied target virtual machine;

wherein without starting the copied target virtual machine,

the host side virtual machine setting unit of the host obtains the setting parameter of the copied target virtual machine from the storage device, and makes the storage area for setting the parameter of the copied target virtual machine accessible from the setting purpose virtual machine, and

the guest side virtual machine setting unit of the setting purpose virtual machine obtains the setting parameter of the copied target virtual machine from the host side virtual machine setting unit of the host, writes the setting parameter in the storage area for setting the parameter of the copied target virtual machine which has been made accessible by the host side virtual machine setting unit of the host, and sets the parameter of the copied target virtual machine.

4. The information processing apparatus of claim 1 further comprising:

a load evaluating purpose virtual machine for carrying out a processing to apply a load to a hardware resource;

a resource monitor for monitoring the load applied to the hardware resource by the processing of the load evaluating purpose virtual machine; and

a load evaluating unit for comparing a monitored value by the resource monitor with a threshold value, if the monitored value is equal to or less than the threshold value, starting a new load evaluating purpose virtual machine, and if the monitored value exceeds the threshold value, deciding a virtual machine operable limit number based on a number of currently operating load evaluating purpose virtual machine.

5. An information processing apparatus setting a parameter of a virtual machine comprising:

a storage device storing a setting parameter to be set for a target virtual machine which is a target for setting the parameter and having a storage area for setting the parameter of the target virtual machine; and

a host having a host OS (Operating System) and a virtual machine setting unit operating on the host OS,

wherein without starting the target virtual machine,

the virtual machine setting unit of the host obtains the setting parameter from the storage device, makes the storage area for setting the parameter of the target virtual machine accessible, writes the setting parameter in the storage area for setting the parameter of the target virtual machine which has been made accessible, and sets the parameter for the target virtual machine.
