Abstract
A system that compares first information corresponding to an amount of a first type of resource used when a first virtual machine is executed in an idle state with second information corresponding to an amount of the first type of resource used when a second virtual machine is executed, and determines whether the second virtual machine is in the idle state based on the comparison.
Claims19
A system comprising:
- circuitry configured to
- acquire first information indicating an amount of a hardware resource of a server used by a first virtual machine executed in an idle state on the server;
- determine, from the acquired first information, a threshold value corresponding to the amount of the hardware resource used by a virtual machine executed in the idle state on the server;
- acquire second information indicating an amount of the hardware resource used by a second virtual machine executed on the server;
- and
- determine whether the second virtual machine is in the idle state based on comparison between the acquired second information and the threshold value, wherein
- a plurality of virtual machines are executed on the server,
- the plurality of virtual machines operate a plurality of types of operating systems, and
- the circuitry is configured to
- cause the server to execute the first virtual machine in the idle state for each of the types of the operating systems;
- acquire the first information with regard to the first virtual machine for each of the types of the operating systems;
- and
- determine the threshold value corresponding to each of the types of the operating systems based on the acquired first information corresponding to each of the types of the operating systems.

A method comprising:
- acquiring first information indicating an amount of a hardware resource of a server used by a first virtual machine executed in an idle state on the server;
- determine, from the acquired first information, a threshold value corresponding to the amount of the hardware resource used by a virtual machine executed in the idle state on the server;
- acquiring second information indicating an amount of the hardware resource used by a second virtual machine executed on the server;
- and
- determining, via circuitry, whether the second virtual machine is in the idle state based on a comparison between the acquired second information and the threshold value, wherein
- a plurality of virtual machines are executed on the server,
- the plurality of virtual machines operate a plurality of types of operating systems, and
- the method further comprises
- causing the server to execute the first virtual machine in the idle state for each of the types of the operating systems;
- acquiring the first information with regard to the first virtual machine for each of the types of the operating systems;
- and
- determining the threshold value corresponding to each of the types of the operating systems based on the acquired first information corresponding to each of the types of the operating systems.

A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing system, cause the system to:
- acquire first information indicating an amount of a hardware resource of a server used by a first virtual machine executed in an idle state on the server;
- determine, from the acquired first information, a threshold value corresponding to the amount of the hardware resource used by a virtual machine executed in the idle state on the server;
- acquire second information indicating an amount of the hardware resource used by a second virtual machine executed on the server;
- determine whether the second virtual machine is in the idle state based on comparison between the acquired second information and the threshold value, wherein
- a plurality of virtual machines are executed on the server and the plurality of virtual machines operate a plurality of types of operating systems;
- cause the server to execute the first virtual machine in the idle state for each of the types of the operating systems;
- acquire the first information with regard to the first virtual machine for each of the types of the operating systems;
- and
- determine the threshold value corresponding to each of the types of the operating systems based on the acquired first information corresponding to each of the types of the operating systems.
