I would like to add geometry and block size passthrough for host devices. See
the patches from Ekaterina Tumanova.
https://lists.nongnu.org/archive/html/qemu-devel/2014-07/msg03791.html

On s390 we have a stricter requirement of passing through geometry and block size for DASD disk devices as this geometry is more than a imaginary number triplet. It is required for proper partition detection and is actually a property of the real (or better emulated on storage servers like DS8x000) disk.
