摘要
[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.
