I can't roll back the driver for that device because I can't boot the system. The only way I can boot into the system is by changing the disk type to IDE but then I cannot roll back the driver because the entire device changed. As far as I can tell the Suse version of the virtio block driver is incompatible with the incompatible with the system but right now I see no way to tell windows "Uninstall the driver completely for the entire system" so that on the next boot it would fall back to the old virtio driver from Red Hat. I tried installing the current stable drivers from this URL: https://fedoraproject.org/wiki/Windows_Virtio_Drivers But Windows refuses and says the driver is already up-to-date. What worries me is that I want to update other win2008r2 guests as well but now fear that they will all be rendered unbootable by such an update.
