Abstract
A simple hypervisor, in addition to a hypervisor, is operated on a computer. A guest OS, the continued operations of which need to be guaranteed, when a fault occurs in the hypervisor is operated on the simple hypervisor, and the other guest OSs are operated on the hypervisor. The hypervisor performs resource scheduling (determining of resources to be allocated to or deallocated from each guest OS) and the simple hypervisor executes, in place of the simple hypervisor, allocation or deallocation of resources to or from the guest OS, the continued operations of which need to be guaranteed.
