When running Windows VMs on OpenShift hosts (AMD64 bare metal EC2 instances) with enabled AWS Windows License Included, you must create the Windows VMs in a license-compliant manner. The number of virtual CPU cores of the Windows VMs must be lower or equal-to the number of cores of the physical node. This important because the number of physical cores are licensed to Microsoft. If the sum of all virtual CPU cores of all VMs running on a physical node are higher than the number of physical CPU cores of the node, then the scenario is called "over-committed CPU utilization".

Background

Users must be restricted to not overcommit virtual CPU cores.

To utilize the windowsli ROSA feature, on uploading a new golden image into the cluster, the default preferences should be set to the windows version related preference, e.g. "windows.11.virtio.dedicated" for windows 11.
