provider networks and vxlan
I have a 4 node setup (controller, networking, compute1, and compute2). All nodes use eth0 for their management access and eth1 for their tenant networking (br-int using VXLAN).
I want to add a single, flat provider network. Can I just attach eth2 on the networking node to my provider network, and VMs accessing that network will do it via br-int over VXLAN? Or does every compute node need a direct attachment to this new provider network?
Regarding flat network provider, take a look at

if you are using linuxbridge for provider network you have to map externel interfecace in neutron-libuxbridge gent.ini file compute node should have seperate public interface for externel access
