Mastering Proxmox - Third Edition

Adding a virtual bridge through CLI

Perform the following steps to create a virtual bridge in Proxmox through the CLI:

1. Log in to the Proxmox node through the console.
2. Open the interface file /etc/network/interfaces using an editor.
3. Add the configuration lines using the following format at the end of the file:

        auto <bridge_name> 
        iface <bridge_name> inet static 
             address 192.168.10.1 
             netmask 255.255.255.0
             bridge_ports ens21 
             bridge_stp off 
             bridge_fd 0 

4. Save the file and exit the editor.
5. Activate the bridge from the CLI using the following command:

        # ifup <bridge_name>

The new virtual bridge should now be activated and running. If virtual machines are to be migrated to other nodes, then the configuration must be duplicated in all the nodes. ...
