Hi Boyang,
Thanks for the update. I guess you need to wait for a few seconds for the
networking service to start in the simulated system (you cannot use the
networking service immediately after the boot up).
Then it should also work If you modify the original boot script like bellow:
if [ "$MY_RANK" == "0" ]
then
sleep 2
/sbin/m5 checkpoint 1
else
sleep 2
fi
Best,
Mohammad
