Abstract:
1. A method of checking, in a virtual machine system comprising a plurality of physical computers including a first physical computer for executing a first virtual machine and a second physical computer capable of executing a virtual machine, whether the first virtual machine can be executed by the second physical computer, logical resources accessible from the plurality of physical computers being limited by setting information set to a plurality of physical interfaces of the plurality of physical computers, the method comprising the following steps performed by the plurality of physical computers of the virtual machine system: acquiring setting information set to a first physical interface of the first physical computer so that the first virtual machine accesses first logical resources; listing second logical resources accessible from a second physical interface of the second physical computer in a case where the acquired setting information is set to the second physical interface and the first virtual machine is executed by the second physical computer with the setting information; and determining whether the first virtual machine can be executed by the second physical computer by comparing the first logical resources and the second logical resources, wherein: if a second physical interface to be checked on accessibility to the second logical resources is exclusively assigned to a virtual machine executed by the second physical computer when the step of listing second logical resources is executed, the step of listing second logical resources comprises:
