TECHNIQUES FOR ESTABLISHING VIRTUAL DEVICES

摘要

Techniques for establishing virtual devices are presented. A legacy control system is encapsulated as a virtual device. The virtual device is isolated within a host hardware associate with a host OS and access to and from the virtual device is authenticated and controlled by the host OS. Legacy hardware used by the legacy control system is connected to the host hardware, thereby permitting the legacy control system to continue to access the legacy hardware when the virtual device processes.
