OK, O_DIRECT actually works with /raid6/virtual/foo.tmp, my guess was 
wrong. Let's just check qemu with strace then. Could you try this:

strace /YOUR/PATH/TO/qemu-system-x86_64 -drive 
file=/raid6/virtual/debian-kaspersky.img,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,aio=native

Thanks,
