  • Introduction to virtio-networking and vhost-net

    In this post we have scratched the surface of the virtio-networking ecosystem, introducing you to the basic building blocks of virtualization and networking used by virtio-networking. We have briefly covered the virtio spec and the vhost protocol, reviewed the frontend and backend architecture used for implementing the virtio interface and have taken you through the vhost-net/virtio-net architecture of vhost-net (host kernel) communicating with virtio-net (guest kernel).

    A fundamental challenge we had when trying to explain things was the historical overloading of terms. As one example, virtio-net refers both to the virtio networking device implementation in the virtio specification and also to the guest kernel front end described in the vhost-net/virtio-net architecture. We attempted to address this by explaining the context of terms and using virtio-net to only describe the guest kernel frontend.

    As will be explained in later posts, there are other implementations for the virtio spec networking device based on using DPDK and different hardware offloading techniques which are all under the umbrella of the virtio-networking.

    The next two posts are intended to provide a deeper understanding of the vhost-net/virtio-net architecture. One post will be intended for architects providing a technical deep dive into the vhost-net/virtio-net and explaining how in practice the data plane and control planes are implemented. The other post intended for developers will be a hands on session including Ansible scripts to enable experimenting with the vhost-net/virtio-net architecture.

    If you prefer high level overviews we recommend you keep an eye out for the virtio-networking and DPDK introductions, to be published in the upcoming weeks.
