You can bring it under netplan control by creating a file using the template above. If you do not have this file, then your system (which might be an upgrade from an older Ubuntu version) is still relying on ‘/etc/network/interfaces’. This is for a host with a single physical NIC named ‘enp1s0’ (yours might be ‘eth0’), static IP of 192.168.1.239 on the 192.168.1.1 network and using Google DNS servers at 8.8.8.8. Go into the “/etc/netplan” directory and you should see a file named “01-netcfg.yaml” or “50-cloud-init.yml” that looks something like: network: On older versions of Ubuntu, you would use ‘ brctl‘, but on bionic you use Netplan. sudo apt install bridge-utils -y Create host bridge using NetPlanīy creating a bridged network, you can have guest VMs share the network connection of the Host machine.Īs an operator, this means you need to use the tools provided at the OS level to create a network bridge. If you haven’t installed KVM on Ubuntu, you can follow the instructions in my article here.Īlthough we don’t directly require it for NetPlan, install the network bridge utilities package for debugging. This bridged network will expose the KVM Guest OS as a peer on the upstream network, with no limits on ingress/egress. In this article, I’ll show how to implement KVM bridged networking on Ubuntu 18.04 bionic using Netplan. In order to expose KVM virtual machines on the same network as your Host, you need to enable bridged networking. UPDATE September 2022: New article for bridged networks on KVM written for Ubuntu 22.04
