Red Hat Summit9.2.2. Installing VirtIO drivers on Windows VMs
VirtIO drivers are paravirtualized device drivers required for Microsoft Windows virtual machines (VMs) to run in OpenShift Virtualization. The drivers are shipped with the rest of the images and do not require a separate download.
The container-native-virtualization/virtio-win container disk must be attached to the VM as a SATA CD drive to enable driver installation. You can install VirtIO drivers during Windows installation or added to an existing Windows installation.
After the drivers are installed, the container-native-virtualization/virtio-win container disk can be removed from the VM.
