Configure Network

The Configure Network menu option provides a graphical editor for the host’s netplan configuration. It allows you to manage network interfaces, bonds, VLANs, and bridges without manually editing YAML files.

How It Works

  • Reads the current netplan configuration and network device status

  • Displays devices in a table with their type, name, addresses, and status

  • Supports adding, editing, and removing network devices

  • Generates and previews the resulting netplan YAML before applying

Supported Device Types

The editor supports all device types defined in netplan:

  • Ethernet — Physical network interfaces

  • Bond — Link aggregation (active-backup, balance-rr, 802.3ad/LACP)

  • VLAN — 802.1Q tagged interfaces

  • Bridge — Linux bridge devices

Workflow

  1. Select Configure Network from the main menu

  2. The current network devices are listed in a table

  3. Use the buttons to:

    • Add — Create a new device definition

    • Edit — Modify the selected device

    • Remove — Delete a device definition

    • Preview — View the generated netplan YAML

  4. When ready, select Save to apply changes

Applying Changes

When you save:

  1. The existing netplan YAML is backed up

  2. A new configuration is written to /etc/netplan/60-mvm.yaml

  3. netplan apply is executed to activate the changes

  4. If the network becomes unreachable, an automatic rollback restores the previous configuration

Warning

Network configuration changes can cause loss of connectivity. Ensure you have physical or iLO console access before modifying network settings.

Validation

  • IP addresses must be in CIDR notation (e.g., 192.168.1.10/24)

  • Device names must reference existing physical interfaces or previously defined virtual devices
