Title: Xvisor VirtIO CAN: Fast virtualized CAN

Abstract: Nowadays, vehicles are embedding more and more electronics to support new functions such as driver monitoring, lane keeping and adaptive cruise control. However, adding electronics makes vehicles more expensive. Fortunately, virtualization, via a hypervisor, reduces the number of embedded chips in vehicle by running different guests, i.e. Operating Systems (OSes), offering several services on the same board.

As the communication between embedded controllers is compulsory for vehicles to function, an optimized virtualization of the Controller Area Network (CAN) bus becomes mandatory. CAN bus virtualization is challenging as it has to tackle the CAN arbitration mechanism and to provide CAN frame broadcast in a transparent manner. In this paper, we use the VirtIO virtualization interface with a virtual CAN service and framework to manage virtualized system external and internal CAN messaging.
