I made an evironment as Nova Controller + Nova Network + Nova Compute on one physical host, but if I need a distributed environment and want to make Nova Controller, Nova Network and Nova Compute seperate from each other. So Quantum+OVS must be installed on Nova Compute node, is it needed to be installed on Nova-network node or Nova-Controller node? Thanks.
