Abstract This document will show how to configure libvirt with openvswitch so that VMs could use openvswitch directly. This is useful if the openvswitch has a trunk connection with your switch that carries multiple VLANs. Requirements You need the following Ubuntu 24.04 cockpit - can access VM through web openssh-server qemu-kvm libvirt-daemon-system cockpit-machines Setup Must have dedicated physical port which is linked to your switch. We will be using ` eno1 ` here. Create openvswitch bridge $ ovs-vsctl add-br br0 # add physical interface $ ovs-vsctl add-port br0 eno1 # showing $ ovs-vsctl show Bridge br0 Port br0 Interface br0 type: internal Port eno1 Interface eno1 ovs_version: "3.3.0" Create a br0 for virsh net $ cat libvirt-br0-simple.xml <network> ...
