Abstract
Lack of freedom in the operation of terminals has been a problem. On the other hand, there has been concern that allowing freedom of operation would negatively impact systems. A virtual computer device is provided with a memory unit and a CPU. The CPU executes an access program, which has the CPU input from or output to the memory unit in accordance with a received input/output request, and a VM monitor which implements a virtual computer in the CPU. Under the control of the VM monitor, the CPU executes a VM program which sends a input/output request to the access program, and via the access program, has the CPU input from or output to the storage device.
Claims12
1-14. (canceled)
A virtual computer device which
- comprises a memory unit which includes an area (other area) which a VM program, executed under the control of a VM monitor, can not access,
- executes, under the control of a host OS, an access program to perform input from or output to the other area and the VM monitor to realize a virtual computer, and
- executes, under the control of the VM monitor, the VM program to perform input from or output to the other area using the access program.
A computer readable non-transitory medium recording thereon a virtual computer program comprising an access program and a VM program wherein,
- by a computer comprising a memory unit which includes an area (other area) the VM program, executed under the control of a VM monitor, can not access, and executing, under the control of a host OS, the VM monitor to realize a virtual computer,
- the access program is executed under the control of a host OS to perform input from or output to the other area and
- the VM program is executed under the control of the VM monitor to perform input from or output to the other area using the access program.
A control method wherein
- a computer comprising a memory unit which includes an area (other area) the VM program, executed under the control of a VM monitor, can not access, and executing, under the control of a host OS, the VM monitor to realize a virtual computer,
- executes the access program under the control of a host OS to perform input from or output to the other area and
- executes the VM program under the control of the VM monitor to perform input from or output to the other area using the access program.
