Abstract: A physical server of a virtual machine (VM) priority control system transmits priority group setting information in which the amounts of resource usage of VMs and priority groups to which the VMs belong are stored to a controller. The controller determines a priority group to which each VM is desired to belong on the basis of an acquired amount of resource usage of the VM, generates dummy VMs corresponding to vacancies belonging to each group, and determines whether performance of each VM can be guaranteed. Further, the controller determines a new current priority group of the VM by exchanging the current priority group of the VM with the current priority group of a pair whose priory groups are paired with those of the VM among pairs of the current priority group and the desired priority group of each of the VMs and the dummy VMs.

Abstract: [Problem] Even when there is no vacancy in a priority group to which a VM is desired to belong, performance guarantee of the VM is continuously realized by migrating a VM. [Solution] In a VM migration system 100, a controller 20 determines a priority group to which a VM whose performance is insufficient is desired to belong based on the amount of resource usage of each VM 1 and priority group setting information 14 acquired from a physical server 10. Upon acquiring performance guarantee failure alarm information, the controller 20 selects a VM to be migrated from VMs currently belonging to a priority group in which there are no vacancies, selects a physical server having the largest margin as another physical server to which the VM is to be migrated, and transmits migration instruction information to the physical server. The physical server migrates the selected VM to the other physical server.

The controller 20 determines a priority group to which each VM is desired to belong on the basis of an acquired amount of resource usage of the VM, generates dummy VMs corresponding to vacancies belonging to each group, and determines whether performance of each VM can be guaranteed.
