Hm perhaps I should mention I don't included any SCSI low-level driver
in my DomU, but for my understanding, this should also be no problem.
The DomU kernel doesn't know anything about the underlying hardware and
I didn't compile in physical hardware access, so I'm curios about why
SCSI low-level is shown in menuconfig at all. Might this be a bug?
