Created attachment 1260757 [details] engine.log (full), VM name in the question is: "delmewin7413".
I suppose you can re-enable the virtio-scsi checkbox in the dialog again, right? Does the template have virtio-scsi disks?
Confirmed on the setup - during "Create VM from Template" dialog the virtio scsi checkbox is not checked even when the template has virtio-scsi disks. Seems to be just a GUI issue
actually, the template doesn't have it in the first place. That was fixed just recently in bug 1422374 *** This bug has been marked as a duplicate of bug 1422374 ***
