With PoC FDP-2761 we evaluate VDUSE-based secondary networks for KubeVirt VMs in OpenShift. It moves networking of KubeVirt virtual machines to userspace with help of the vhost-vdpa protocol. The setup requires:

• A Kubernetes device plugin that creates VDUSE/vhost-vDPA ports in OVS and their associated vhost-vDPA character devices (FDP-1513).
• A new CNI with the minimum required functionality to expose the vhost-vDPA character device, provided by the new device plugin (FDP-1513), to a pod. It will serve as a reference implementation for customers such as Orange (FDP-1516).
• KubeVirt support for attaching VMs to userspace networks using the vhost-vdpa protocol (FDP-1515).

All the components mentioned above must now be integrated in our build, deployment and testing tools for OCP with modified network components – namely, build.sh, cluster.sh and beaker.sh in jmeng/ovs-ci-with-ocp.
