Kevin, here is a fixup for the geometry detection. We tried to be overly clever and calculate the cyclinder size for devices > 64k cyls. Now this is wrong for the cyls parameter as the interface only has 16bit. Large DASD devices have a special token (0xfffe) that indicate to the DASD related code, that you have to calculate the cyls size yourself.
Without this patch QEMU cannot pass through bigger DASD disks and complains "cyls must be between 1 and 65535" Christian Borntraeger (1): block/raw-posix: avoid bogus fixup for cylinders on DASD disks block/raw-posix.c | 7 ------- 1 file changed, 7 deletions(-) -- 2.3.0
