Encapsulation of an application for virtualization

Embodiments relate to a method for encapsulating a hardware application for virtualization. The method surrounds the hardware application with a service layer controller and ring interfaces. The ring interfaces dictates a virtual function that the hardware application is running. The method controls the hardware application so that the hardware application is reset in between each of a plurality of running jobs. The method tags, by the ring interfaces, each of a plurality of requests with an identifier signifying a virtual function that the respective request belongs to. The method ensures that there are not any outstanding requests following a quiesce of the hardware application.
