     -smp 2,maxcpus=2,cores=2,threads=1,sockets=1           \
     -drive file=fedora16-hd0.img,if=virtio,boot=on         \
     -drive file=fedora16-hd1.img,if=virtio,boot=off        \
     -net nic,macaddr=52:54:00:12:34:16,model=virtio -net tap

F14 is no longer supported. If anyone is still affected by this bug with newer
qemu versions (fedora 16 or 17), please reopen this report.
