How to add a virtual MAC address to a flexible IP

Reviewed on 22 January 2024Published on 26 May 2021

Virtual MAC addresses are virtual interface identifiers and are required for virtualization. If you run multiple virtual machines on one physical Elastic Metal server, you can configure the MAC address of its virtual network interface to the virtual MAC associated with the flexible IP to ensure network connectivity of the virtual machine.

Before you start

To complete the actions presented below, you must have:

  • A Scaleway account logged into the console
  • Owner status or IAM permissions allowing you to perform actions in the intended Organization
  • An SSH key
  • An Elastic Metal server installed

Virtual MAC addresses are only required for virtualization purposes. If you want to configure the flexible IP as a second interface on the host OS, no virtual MAC is required.

  1. Click Elastic Metal in the Bare Metal section of the Scaleway console side menu. The Elastic Metal dashboard displays.

  2. Click the Flexible IPs tab.

  3. Click «See more Icon» next to the flexible IP you want to configure. The configuration menu of the flexible IP displays.

  4. Click More info to see detailed information about the IP address.

  5. Scroll down to the Mac address section and click Add Mac address:

  6. Choose the desired type of virtual MAC address. You can choose from VMware, XEN or KVM. It is recommended to choose the type corresponding to your virtualization technology. Confirm by clicking on Generate MAC Address.

    If the virtual MAC address is no longer needed, you can remove it from the flexible IP by clicking on the Delete button.

For more information how to configure the flexible IP on a virtual machine, refer to our documentation.
