That basically defaults to whatever qemu was installed by your distro:
Xen installs qemu to /usr/lib/xen/bin, so you would need:

device_model_override = "/usr/lib/xen/bin/qemu-system-i386"

But actually if you just add:

device_model_version = "qemu-xen"

xl should automatically look for qemu-system-i386 under
/usr/lib/xen/bin.
