Hi, you can use the virtio drivers from the Fedora Project. I didn't have problems on W2k12 and W2k12R2.

Someone on the CentOS ML reported his Windows 2008r2 VM on top of KVM+VirtIO PV ended up unbootable after he installed the SUSE Network and Storage drivers from the Optional Updates channel. I've just checked now and it's the case, the system blue screens after reboot. Will test 2012r2 shortly. It'd be best if you don't install those updates/drivers for now, looks like someone in Redmond didn't do his homework. -- Sent from the Delta quadrant using Borg technology!
