  In conventional virtual machine systems, it is possible to easily create virtual machines with functions such as virtual machine duplication and provisioning from templates, so by proceeding with virtualization without proper design and management, A sprawl phenomenon in which virtual machines proliferate randomly occurs, resulting in a state in which virtual machines cannot be properly managed, and there is a problem in that available resources are wasted. However, if there is an application running even in an unnecessary virtual machine, resources according to the priority order are allocated. Therefore, there is no effect of suppressing the sprawl phenomenon of the virtual machine, and wasteful consumption of resources cannot be suppressed.

  In view of such circumstances, the present invention is intended to suppress the sprawl phenomenon in which virtual machines in a virtual machine system proliferate in a disorderly manner and to provide flexible management of available resources.

  The invention according to an embodiment of the present invention monitors the resource usage status of a virtual machine running on a virtual machine device and an application running on the virtual machine, changes resource allocation to the virtual machine according to a preset policy, Automatically save and delete machines.

  The invention according to another embodiment is used effectively in accordance with a preset policy in a virtual machine device having an application running on a virtual machine on the virtual machine device, monitoring the resource usage status of the virtual machine and the application. If a virtual machine that does not exist is detected, it is possible to easily identify the problematic virtual machine by automatically changing the resource allocation to the virtual machine, stopping, saving, and deleting the virtual machine. A means for suppressing wasteful consumption and effectively reusing it is provided.

  In the invention according to another embodiment, dynamic resource reallocation according to virtual machine resource usage and virtual machine relocation are effective means for a required virtual machine. Therefore, resources corresponding to the amount of use continue to be allocated to unnecessary virtual machines, resulting in wasteful consumption of resources and preventing sprawl of virtual machines. In the present invention, unnecessary virtual machines are detected based on policies and resource usage statuses, and not only the reallocation of virtual machine resources but also actions such as stop, delete, and save are provided. Real control.

  According to the virtual machine system of the present invention, the sprawl phenomenon in which virtual machines in a virtual machine system proliferate randomly is suppressed, and flexible management of available resources is provided. By monitoring the resource usage status at the virtual machine and application level, it is possible to determine whether the virtual machine is normal or abnormal flexibly and finely. In addition, resource allocation to abnormal virtual machines is automatically changed according to a preset policy, and virtual machines are automatically stopped, saved, and deleted, so that wasted resources are efficiently released and reused effectively. It becomes possible to do.

The policy information database 300 for storing the policy information is provided, and the virtual machine apparatus provides functions for monitoring resource usage, changing resource allocation to virtual machines, stopping, saving, and deleting virtual machines.

  The management virtual machine 110 operates on the virtual computer device 100. One or more virtual machines 120 also operate on the virtual computer apparatus 100. FIG. 1 shows an example in which two virtual machines 120 operate on the virtual computer apparatus 100, but the number of virtual machines operating on the virtual computer apparatus 100 is not limited to two, and an arbitrary number of virtual machines The machine can be operated.

  The application monitoring module 122 on each virtual machine 120 operating on the virtual machine device 100 monitors the resource usage status of each application 123 operating on the virtual machine in cooperation with the OS 121 on the virtual machine. Note that the number of applications operating on each virtual machine is not limited to two, and an arbitrary number of applications can be operated for each virtual machine.

  In addition, the application information collection module 113 on the management virtual machine 110 operating on the virtual machine device 100 acquires the resource usage data of the application 123 from the application monitoring module 122 on each virtual machine 120, and periodically records the history information. Store in database 200.

  The virtual machine monitoring module 112 on the management virtual machine 110 monitors the resource usage status of each virtual machine 120 on the virtual machine device 100 by cooperating with the OS 111 on the management virtual machine 110 or the virtual machine monitor. Based on the resource usage status acquired as a result of the above, the resource usage data of the virtual machine is periodically stored in the history information database 200.

  If the policy control module 114 on the management virtual machine 110 detects an abnormal state that falls below the application resource usage threshold, the policy control module 114 sends a warning email to the administrator email address based on the preset policy. Then, by executing state change actions for the virtual machine such as changing the resource allocation to the virtual machine, stopping, saving, and deleting the virtual machine, the resources that are wasted are released.

  If the policy control module 114 on the management virtual machine 110 detects an abnormal state that is below the threshold for using virtual machine resources, the policy control module 114 sends a warning email to the administrator email address based on the preset policy. Then, by executing state change actions for the virtual machine such as changing the resource allocation to the virtual machine, stopping, saving, and deleting the virtual machine, the resources that are wasted are released.

  Changing the resource allocation of the virtual machine, which is a state change action for the virtual machine 120, changes the resource allocation to the virtual machine 120 to the minimum. Stopping the virtual machine shuts down the virtual machine 120. To delete a virtual machine, the virtual machine 120 is deleted from the virtual machine device 100 after being shut down. To save the virtual machine, the virtual machine 120 is shut down, exported to the history information database 200, and then deleted from the virtual computer apparatus. The policy control module stores state change action execution information in the history information database 200.
