PURPOSE:To set the occurrence of the protection exception of a virtual computer same as that in the case which a program is executed in a real computer by generating the interruption of the protection exception in the virtual computer or a guest computer if storage protection information is detected when a TLB is collated. CONSTITUTION:If storage protection information is detected when the address conversion buffer (TLB) is collated, the interruption of the storage protection exception is generated in the virtual computer or the host computer corresponding to the storage protection information. Thus, the storage protection of the host and the quest can be discriminated and detected, and the storage protection exception by the guest can interrupt in the guest and that by the host in the host, whereby a program which runs in the guest is interrupted similarly to the case in which the program is executed in the real computer. Thus, the difference with the execution in the real computer is eliminated and the original action of the virtual computer can be executed.
