This is what my qemu config roughly looks like for freebsd...
disk="${HOME}/nfs/qemu/$lock.qcow2"
net="-net nic,model=virtio -net user,hostfwd=tcp::${port}-:22"
drive="-drive if=virtio,media=disk,index=0,file=${disk}"
serial="-nographic -serial mon:stdio"
console="-display curses"
qemu="qemu-system-x86_64 -accel kvm"
$qemu $name $mem $nic $net $drive $serial
