Bringing virtual machines into Kubernetes introduces unique networking challenges, especially in public cloud environments. Traditional Kubernetes Networking plugins, designed for ephemeral containers, fall short in supporting virtualization-specific needs like stable IPs during live migrations and network segmentation. This talk explores how the CNCF projects OVN-Kubernetes and KubeVirt work together to provide networking that supports the needs of virtual machines on Kubernetes.

OVN-Kubernetes is a robust network plugin for Kubernetes clusters. KubeVirt is a virtualization plugin that manages the lifecycles of VMs on Kubernetes. In this session, we will introduce these projects and walk you through:

- How to set up multiple, customizable networks in Kubernetes

- How to connect your applications and VMs to separate, isolated networks

- How to perform live VM migration across Layer 2 networks without downtime

- Best practices for configuring your networking setup based on your platform—whether you're running in the cloud or on-prem

Join us to learn how to build flexible, VM-friendly networking on Kubernetes.
