Claim 2:
3. The VM performance guarantee system according to claim 1,
wherein
the data acquisition unit of the controller acquires a resource use amount and performance values of each of the plurality of VMs belonging to the priority groups from the physical server as actual data in operation for a predetermined period of time,
the controller further comprises
a learning functioning unit, including one or more processors, configured to generate learning result data used to estimate a performance value based on the resource use amount by machine learning based on the actual data, and
a performance value estimating unit, including one or more processors, configured to calculate a performance estimation value of each of the plurality of VMs using the learning result data based on a resource use amount of each of the plurality of VMs at a present time which is acquired from the physical server, and
the priority changing determination unit determines whether to change the priority group of each of the plurality of VMs by determining whether or not the first condition is satisfied or whether or not the second condition is satisfied, using the calculated performance estimation values.
