devstack is not for production environments... But answering your questions, you can change
nova.conf as you like and then unstack and rejoin-stack

So I need to modify "compute_scheduler_driver" in "/etc/nova/nova.conf" and use a new scheduler class. But how can I do this via devstack? I tried to add "SCHEDULER=~~" in "devstack/localrc" but it didn't work. Anyone have any idea on that?

But the only way to do so (as far as I'm concerned) is to ./unstack.sh + ./stack.sh, which will overwrite all the previous changes in "nova.conf". Is there any way that I can stop a certain service and then start it over to use the new configurations.
