Hey,
Just a heads up - on 32 bit hosts where qemu was using preadv and
pwritev, we were seeing data corruption due to file offset being
truncated:
https://bugzilla.redhat.com/533063
https://bugzilla.redhat.com/526549
The glibc headers fix is posted here:
http://sources.redhat.com/ml/libc-hacker/2009-11/msg00001.html
Cheers,
Mark.

Do you expect to get the fix into Fedora and other distros ASAP or
should we aim for a qemu workaround (using raw system calls)
