<p>In the conventional virtual computer system, in order to provide the same access method for the host and the guest, there exists a great overhead for the operations to save and to restore the host resource at a change-over between the host and the guest. In the disclosed system, the same access method is provided for the host and the guest and at the same time the overhead is removed. The host resource (11) and the guest resource (12) are separately allocated. There is disposed a mode line (5) indicating whether the present state is associated with the host or the guest. There is also disposed an access controller (2, 3) which operates such that when the mode line indicates the host, the host resource is accessed, and when the guest is indicated, the guest resource is accessed.</p> |
