An operation management apparatus includes a processor. The processor generates a VM load model for each virtual machine running on an information processing system, generates resource utilization rate estimation data based on VM load models of a virtual machine group running on the physical machine and a VM load model of a first virtual machine, for each of physical machines except for a first physical machine on which the first virtual machine is running, generates a resource competition occurrence model based on the resource utilization rate of the physical machine, calculates a statistical value of competition occurrence probabilities of the resource, for each of the physical machines except for the first physical machine, based on the resource utilization rate estimation data and the resource competition occurrence model, specifies the migration destination physical machine based on the statistical value, and outputs information of a specified migration destination physical machine.
