What does "ps aux | grep qemu" show as your qemu command line? Also
"netstat -a | grep qemu" might be interesting.

When I have an issue with qemu I often specify the device model in my
guest configuration as a script containing:
        echo $@ > /tmp/qemu-dm
        sleep 1h

Then immediately after running "xl create" I can examine /tmp/qemu-dm
and run the qemu by hand in the foreground, or under gdb etc. (there is
a timeout in xl waiting for qemu to announce itself so you need to be
reasonably prompt...)
