bug 9896: RHEL 6 doesn;t support to attach an SCSI disk to a windows VM, then I have to attach a virtio disk.

Browse Source 
So for a windows guest, the root disk is an IDE disk(in case there is no virtio driver installed inside guest), but all the data disks will be virtio disks.
That means if you want this feature, people need to install virtio disk driver inside windows guest to get data disk work.
status 9896: resolved fixed
