In addition to a hypervisor, a simple hypervisor is run on a computer. On the simple hypervisor, a guest OS of which continuous operation even at the time of hypervisor failure is desired to be guaranteed is operated, while on the hypervisor, another guest OS is operated. Resource scheduling (determination of a resource to be allocated or collected with respect to each guest OS) is performed by the hypervisor, while allocation or collection of a resource with respect to the guest OS of which continuous operation is desired to be guaranteed is implemented by the simple hypervisor for the hypervisor. |
