Computer readable medium, method, and management device for determining whether a virtual machine can be constructed within a time period determined based on historical data

Abstract

A method includes: when receiving an acquisition request, including performance condition, that requests first virtual machine, determining whether the first virtual machine that satisfies the performance condition is able to be constructed on one of physical machines by referring operation statuses of the physical machines; when the first virtual machine satisfying the performance condition is determined to be unable to be constructed, setting, based on previous determination history of whether second virtual machine that satisfies the performance condition is able to be constructed, a determination period for determining whether the first virtual machine that satisfies the performance condition is able to be constructed, in accordance with time interval at which the second virtual machine that satisfies the performance condition is determined to be able to be constructed; after elapse of a time period corresponding to the determination period, determining whether the first virtual machine is able to be constructed.
