In this article, I show you how to wrap a libvirt virtual network around your OVS fake bridge. You might ask, “Why wrap a libvirt virtual network around an OVS fake bridge when you can just use the OVS bridge directly?” Next, create an XML definition for a libvirt virtual network.

One of the cool things about libvirt is the ability to work with multiple hypervisors and virtualization technologies, including Linux containers using LXC. If you aren’t familiar with Linux containers and LXC, I invite you to have a look at my introductory post on Linux containers and LXC. LTS, as I am.).

Having Linux as your operating system is one of the better decisions you can make concerning your computer’s security. However, many Linux users make the same mistakes of believing that it’s enough just to have it on your computer and only that fact will make all threats simply disappear, when unfortunately the reality is quite different.

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.
