Running out of ideas here - Trying to pass through a GTX 550ti. I am getting the same sort of symptoms as in this old post: http://lime-technology.com/forum/index.php?topic=33354.0 Specifically, no video output and the same error in dev mgr showing 'The device cannot find enough free resources it can use' Except the only devices I am passing through are usb keyboard, the 550ti gpu, and the 550ti HD audio. I created the vm using virtio-win-0.1.118-2.iso.   Initially the vm was set to i440f
