## Abstract

Embodiments of apparatuses, methods, and systems for providing multiple virtual device controllers by redirecting an interrupt from a physical device controller are disclosed. In one embodiment, an apparatus includes a processor, a physical device controller, and virtualization logic. The virtualization logic is to receive a first interrupt from the physical device controller, and in response, send a second interrupt to the processor from one of a plurality of virtual device controllers.

## Claims

### Claim 1

An apparatus comprising:
a processor,
a physical device controller; and
virtualization logic to receive a first interrupt from the physical device controller, and in response, send a second interrupt to the processor from one of a plurality of virtual device controllers.
