The default networking that KVM provides is a private bridge that uses NAT to allow the guest VMs to talk to the outside world. This works for a lot of use-cases and is probably the best default setup. But sometimes I need the VMs to share the network with the host. In many of my past articles that created VMs, I’ve been able to get away with the default networking. But a future project I’m working on will need VMs operating on the host network, so I wanted to document how to do that here.
There are a lot of articles on setting up a public bridge; it seems like a popular topic. But many of the articles are old and don’t use the latest networking configuration software available with Ubuntu or they manage networking and KVM with a GUI interface. I will be using only command-line tools, as I don’t actua
