That should be possible, but you haven't shown your code so I can't say
where you have gone wrong.

What I often do is create qemu-debug.sh:
        #!/bin/sh
        echo "Starting QEMU with: $*" >> /tmp/qemu-dbg.log
        exec /usr/lib/xen/bin/qemu-system-i386 $@

And then using device_model_override to call this instead of calling
qemu directly.
