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. Stefan
