Okay, so if I understand correctly you have CentOS 6.1 host running
FreeBSD and CentOS guest installs to emulated IDE drives.  You're
getting failed I/O requests with EINVAL (22).  You have verified that
dd if=/opt/vm/database.img of=/dev/null iflag=direct reads the image
file without errors.

Can you please try the CentOS guest install with a virtio-blk drive
instead of IDE?  This should show whether this problem is related to
IDE or a general issue in how QEMU accesses the host file.
