How to add a virtual MAC address to a flexible IP

Reviewed on February 11, 2025

Virtual MAC addresses act as virtual interface identifiers necessary for virtualization. When running multiple virtual machines on a single physical Elastic Metal server, you can configure the MAC address of the virtual network interface to match the virtual MAC associated with the flexible IP, ensuring network connectivity for 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 installed Elastic Metal server (how to create an Elastic Metal server)

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 to navigate to flexible IP section. A list of your flexible IPs for Elastic Metal server displays.
3. Click the more icon next to the flexible IP you wish to configure. The configuration menu for the flexible IP will display.
4. Click More info to see detailed information about the IP address.
5. Configure the virtual MAC address:
   • Scroll down to the MAC address section and click Add MAC address.
   • Select the desired type of virtual MAC address (VMware, XEN, or KVM). It is recommended to choose the type that matches your virtualization technology.
   • Confirm by clicking Generate MAC Address.
