Abstract
An OS on a virtual computer at the (n+m)-th stage (n and m represent natural numbers) is caused to recognize a device driver that runs on an OS on the n-th stage virtual computer. Specifically, a shared region is generated in a memory, and the OS at the second stage is caused to recognize, in a pass-through manner, the device driver that runs on the OS at the second stage.
