Hi, I suggest you to read the official documentation [1] which helps to install and configure Quantum + OVS for many use cases. I think you should use 3 NICs for your controller node : eth0 for management network, eth1 for VMs traffic (used by OVS), and eth2 for public network (i.e. Internet). For compute nodes, I suggest using 2 NIC : eth0 for management network and eth1 for VMs traffic.
