Ubuntu Server 17.10 and Netplan

  • Since I'm using KVM on Fedora Workstation I needed to add a isolated interface so I can access my VM from the host. First of all loopback interface was the only thing in /etc/network/interfaces.

    I thought something was broken so I added my ens3 (macvtap-bridge) and ens4 (isolated) interfaces.

    And then none of commands that we normally would use was not available.
    After doing some Google-fu, I found out that Ubuntu Server 17.10 uses NetPlan to manage the network configuraton now.


    The configuration in /etc/netplan/01-netcfg.yaml looks this.

    # This file describes the network interfaces available on your system
    # For more information, see netplan(5).
      version: 2
      renderer: networkd
          dhcp4: yes
           dhcp4: yes

    The supported renderers are NetworkManager NetworkManager and systemd-networkd networkd.

    The following commands is available to generate and apply the configuration.

    # Use /etc/netplan to generate the required configuration for the renderers.
    sudo netplan generate
    # Apply all configuration for the renderers, restarting them as necessary.
    sudo netplan apply
    # Attempt to generate an equivalent configuration to what is specified in /etc/network/interfaces.
    sudo netplan ifupdown-migrate
