The only things that stands out is this before the "read failed" message:

The buffer is unaligned here, yet the file was opened with O_DIRECT
(cache=none). This is strange, since alignment is not related to disk
size.
The other interesting thing is that it's using pread - which means
it's a too old kernel to use preadv and thus a not very well tested
codepath with current qemu.
It may also be that glibc is emulating preadv, incorrectly.
Antoine, can you check this? ltrace may help, or run 'strings libc.so |
grep pread'.
