Doesn't fly. Either every SCSI HBA uses QEMUSG64List (thus making this
aequivalent to the next option from the scsi point of view), or
scsi-disk would have to support both formats.

A device or device set which is always 64-bit would always use
QEMUSG64List. A device which is always 32-bit would use QEMUSG32List.

A scsi-disk can be connected to both 32-bit and 64-bit HBAs though ...

A line has to be drawn. Since we have a limited number of HBAs, and since the performance impact will be minimal, we can safely use 64-bit for scsi.
