Just to be clear about this:

- Disable the driver signature enforcement using any of the methods
- Reboot _before_ installing GPLPV. This is important step.
- Install GPLPV only after you have first rebooted the guest.
- Don't reboot before all the GPLPV drivers are installed and devices
  detected. You might need to rescan the hardware from device manager to
  make that happen.
- Reboot the guest only when GPLPV is fully installed.
