I added "aio=native" and it crashed.
If it helps, I ran config like so:
./configure --target-list=x86_64-softmmu --disable-curses  --disable-curl --
audio-drv-list=alsa --audio-card-list=sb16,ac97,hda --enable-vnc-thread --
disable-bluez --enable-vhost-net --enable-spice

and I've attached config.log, as well as the output of configure.
