In this session, AGL Virtualization Expert Group and Container and Mesh Expert Group will jointly give a presentation on how AGL is approaching Software defined Vehicles, including defining the standard device virtualization framework “VirtIO” across automotive cloud & edge, and laying the groundwork for micro-service orchestration for on-board automotive systems.

      • Abstract:

        virtio-loopback is a virtio Hardware Abstraction Layer (HAL) for non-virtualized environments drafted by Virtualization Expert Group (EG-VIRT). The objective of virtio-loopback is to abstract hardware dependencies for the AGL framework/applications in a way that user space programs can be run unmodified on real hardware, virtualized systems and in the cloud. During this presentation we will go through the design and results of the virtio-loopback implementation activity.

  • Leonardo Garcia will present their progress in the OSS virtio backend
