Abstract
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.
Claims20
A machine-implemented method implemented in a non-transitory computer-readable storage medium for execution on a machine, comprising:
- creating, by the machine, a virtual image that packages native hardware having a native processing environment and a native operating system (OS) on host hardware that processes a different OS;
- and
- starting, by the machine, the virtual image as a guest OS on the host hardware.
A machine-implemented method implemented in a non-transitory computer-readable storage medium for execution on a machine, comprising:
- establishing, by the machine, a virtual device from a native processing environment and its native Operating System (OS);
- and
- initiating, by the machine, the virtual device within host hardware of a host OS, the virtual device having access to native hardware from the host hardware.
A machine-implemented system, comprising:
- legacy hardware devices having a legacy processing environment and a legacy Operating System (OS);
- and
- host hardware having a host processing environment and a host OS;
- wherein a virtual device encapsulates the legacy hardware having its legacy processing environment and legacy OS on the host hardware and controlled via the host OS.
