In previous posts, I’ve shown you how to use Open vSwitch (OVS) with VLANs through fake bridges , as well as how to wrap libvirt virtual network around OVS fake bridges. To make VLANs work with OVS and libvirt, two things are necessary: First, you must define a libvirt virtual network that contains the necessary portgroup definitions.
