What are the services one need to run on a compute node?
I have a controller which runs all the services as specified in devstack
and since I am running quantum with openvswitch I have also added q-svc and
q-agt to this node. Now I need to start a second node which will be only a
compute node. devstack documentation says one need the following services:
ENABLED_SERVICES=n-cpu,n-net,n-api,n-vol
Is this correct? I thought all I need to run on the second node is n-cpu
and q-agt. What are the required services?

If I run the n-cpu and q-agt my n-cpu crashes and the crash seems to be
related to not having a connection to the mysql server on the controller
node. I assume i do not need a mysql server on the compute node. Is this
correct?

Any help is much appreciated. Thanks.
