Our bridge configuration is ready, however, as it is, it will not survive a machine reboot. To very that the address was added to the interface, we run: $ ip addr show br0ĩ: br0: mtu 1500 qdisc noqueue state UP group default qlen 1000

Link/ether 18:a6:f7:0e:06:64 brd ff:ff:ff:ff:ff:ffĪssigning a static IP address to the bridgeĪt this point we can assign a static IP address to the bridge. To verify the interface was added to the bridge, instead: $ sudo ip link show master br0ģ: enp0s29u1u1: mtu 1500 qdisc fq_codel master br0 state UP mode DEFAULT group default qlen 1000 To add the interface to bridge, the command to run is the following: $ sudo ip link set enp0s29u1u1 master br0 In this case we will use an additional interface, enp0s29u1u1: this is an interface provided by an ethernet to usb adapter attached to my machine.įirst we make sure the interface state is UP: $ sudo ip link set enp0s29u1u1 up Notice that you can’t use your main ethernet interface in this case, since as soon as it is added to the bridge you would loose connectivity, since it will loose its IP address. In this step we will add a host physical interface to the bridge.

Adding a physical ethernet interface to the bridge Now that the new bridge is created, we can proceed and add the physical interface to it. Link/ether 26:d2:80:7c:55:dd brd ff:ff:ff:ff:ff:ffĪs expected, the new bridge, br0 was created and is now included in the output of the command above. To verify the bridge is created we do as before: $ sudo ip link show type bridgeĥ: virbr0: mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000Ĩ: br0: mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 Let’s say we want to name this bridge br0 we would run the following command: $ sudo ip link add br0 type bridge To create a new bridge, we can still use the ip command.

Sometimes, however, we want to achieve a full bridgining connection, where the guest devices are connected to the host LAN, without using NAT, we should create a new bridge and share one of the host physical ethernet interfaces. The default network provides a very straightforward way to achieve connectivity when creating virtual machines: everything is “ready” and works out of the box. Use bridged networking for virtual machines No physical interfaces should ever be added to the virbr0 bridge, since it uses NAT to provide connectivity. For the sake of this tutorial I created and launched a Debian (Buster) virtual machine if we re-launch the command we used above to display the bridge slave interfaces, we can see a new one was added, vnet0: $ ip link show master virbr0Ħ: virbr0-nic: mtu 1500 qdisc fq_codel master virbr0 state DOWN mode DEFAULT group default qlen 1000ħ: vnet0: mtu 1500 qdisc fq_codel master virbr0 state UNKNOWN mode DEFAULT group default qlen 1000 Other virtual interfaces will be added to the bridge when we create and launch virtual machines. The virbr0-nic interface is a virtual ethernet interface: it is created and added to the bridge automatically, and its purpose is just to provide a stable MAC address (52:54:00:48:3f:0c in this case) for the bridge. The result of running the command is: 6: virbr0-nic: mtu 1500 qdisc fq_codel master virbr0 state DOWN mode DEFAULT group default qlen 1000Īs we can see, there is only one interface currently attached to the bridge, virbr0-nic. To show the interfaces which are part of the bridge, we can use the ip command and query only for interfaces which have the virbr0 bridge as master: $ ip link show master virbr0 In our case the command above returns the following output: 5: virbr0: mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000 We can verify that the bridge exists using the ip command: $ ip link show type bridge In this case the result is the following: Īs we can see, the default network is based on the use of the virbr0 virtual bridge, and uses NAT based connectivity to connect the virtual machines which are part of the network to the outside world. To obtain detailed information about the network, and eventually modify it, we can invoke virsh with the edit subcommand instead, providing the network name as argument: $ sudo virsh net-edit defaultĪ temporary file containing the xml network definition will be opened in our favorite text editor. In the example above we used the -all option to make sure also the inactive networks are included in the result, which should normally correspond to the one displayed below: Name State Autostart Persistent
