Learn how to configure the public interface for your Public Cloud instances within your vRack.
Unlike Windows instances created in the public network, Windows instances created with private network mode (vRack) do not have their Windows licenses automatically enabled. In this case, you must activate the license manually to access all Windows services.
Requirements
- A Public Cloud project in your OVHcloud account
- Access to the OVHcloud Control Panel
- An OpenStack user account
We recommend that you read our guide on Accessing the Horizon interface to familiarize yourself with Horizon.
Instructions
Attach an "Ext-Net" public port to an instance
Via Horizon
Log in to the Horizon interface using the method listed in the first part of this guide.
Choose the proper work zone.
Select Compute and then Instances from the menu.
To add an interface, click on the arrow in the “Actions” column to access the possible actions on the instance. Select Attach Interface:
Select your interface and confirm.
Via the OpenStack API

With the previously retrieved items, you can create a public port named "Ext-Net" on the subnet "Ext-Net" and attach it to the instance:
openstack port create --network b2c02fdc-ffdf-40f6-9722-533bd7058c06 Ext-Net

Attach the port to the instance:
openstack server add port <server_id> <port_id>
Activate your Windows license
To activate Windows, you must go through Powershell.
Once you have logged in to your Windows instance, right-click on the Start menu and select Windows PowerShell.
Enter the following command:
slmgr.vbs -ato
The Windows license will be activated for 180 days.
You will need to repeat this operation every 180 days.
To check the license status and expiration date, use the following command:
slmgr.vbs -dli
