[Qemu-devel] "A disk read error occurred"

["Alexander (Sasha) Sirotkin"]

For some reason when I try to boot qemu with -hda /dev/sda (or -hda
/dev/hda), i.e. to use the whole disk, it fails with the above error
"A disk read error occurred". This happens only on IBM/Lenovo laptops
(tried a few models), while it works just fine on any desktop I can
get my hands on. Probably has something to do with bios...

Any suggestions ?

Thanks
