Stáhl jsem si soubor TEST_32M_public.img

# wget http://vserver.13thfloor.at/Stuff/QEMU/TEST_32M_public.img.bz2

no, this is a disk image, including a partition table,
with qemu you use it like this:

 qemu-fast -nographic -m 128 -snapshot -hda TEST_32M_public.img

so you have to use the offset of the first partition
for a loop setup (63*512 = 32256)

HTH,
