Try;

primitive st-pace1 stonith:external/xen0 \
        params hostlist="pace1" dom0="xentest1" delay="15" \
        op start start-delay="15s" interval="0"

The idea here is that, when both nodes lose contact and initiate a fence, 'st-pace1' will get a 15 second reprieve. That is, 'st-pace2' will wait 15 seconds before trying to fence 'st-pace1'. If st-pace1 is still alive, it will fence 'st-pace2' without delay, so pace2 will be dead before it's timer expires, preventing a dual-fence. However, if pace1 really is dead, pace2 will fence it and recovery, just with a 15 second delay.
