Can you explain how to remove the Compute Service (Nova) from a controller node in OpenStack?
I am using Linux Ubuntu 14.04.

You want to go through the same steps as removing a compute node. Surprisingly, this not well documented; in particular I don't see instructions on the OpenStack documentation site at all. However, the instructions at Oracle look good to me.
Summary: Disable the compute service, so that no new instances are scheduled. Migrate all instances away. Remove the node from Nova's database with openstack compute service delete. Do the same with Neutron agents. Now you can remove the nova-compute packages and the Neutron agent packages.
