Claim 1:
2. The VM performance guarantee system according to claim 1, wherein
the controller further comprises
a test tool functioning unit, including one or more processors, configured to instruct 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,
a learning functioning unit, including one or more processors, configured to
receive a resource use amount and performance values obtained through the operation of the test tool as test result information from the physical server, and
generate 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, 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.
