[ovirt-users] oVirt 3.4 could not install Windows server 08 R2 with virtio / virtio SCSI

Hi All: I am new to oVirt and just installed oVirt for a try. Any one could install Win Server 08 R2 with virtio or virtio SCSI from oVirt 3.4? I am already changed the driver during the installation with virtio-win-0.1-74.iso, however I try what ever driver directory for AMD64 it show the device but when I click to select and then click OK, it always say "No new device could be found. Make sure the driver files are correct and located on the driver installation media". Does any other see this issue, and know how to solve? Many thanks Best Regards, Paul.LKW
