Claim 4:
5. The VM performance guarantee method according to claim 4, further comprising:
instructing, by the controller, each of the plurality of VMs belonging to the priority groups to execute a test tool to be operated by varying a load in a predetermined pattern;
receiving, by the controller, a resource use amount and performance values obtained through the operation of the test tool as test result information from the physical server;
generating, by the controller, learning result data to be used to estimate a performance value based on the resource use amount by machine learning based on the test result information;
calculating, by the controller, 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
determining, by the controller, 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.
