Abstract
An apparatus extracts, for each virtual machine, a first time at which a first live migration has been performed and a first time-interval that has been taken for the first live migration, from log information storing events of the first live migration. The apparatus extracts, for each virtual machine, load information from a load history in which the load information including a CPU usage rate and a memory usage amount is stored at predetermined intervals for each virtual machine, and generates a model that predicts a second time-interval to be taken for a second live migration expected to be performed for each virtual machine, from the load information at the first time and the first time-interval. Upon receiving an instruction for predicting the second time-interval, the apparatus predicts the second time-interval from the model, and provides the predicted second time-interval to be taken for the second live migration.
