To determine, when a virtual machine is executed by an arbitrary machine, whether the virtual machine can access computer resources required for the virtual machine, provided is a method of checking a possibility of executing a virtual machine including a first physical computer for executing a first virtual machine and a second physical computer capable of executing a virtual machine. The method includes the steps of: acquiring information on first logical resources; acquiring setting information set to a adaptor of the first physical computer so that the first virtual machine accesses the first logical resources; listing second logical resources accessible when the first virtual machine is executed by the second physical computer by setting the setting information to a adaptor of the second physical computer; and determining whether the first virtual machine can be executed by the second physical computer by comparing the first and second logical resources.
