I highly recommend using the correct config files vs the symlink configuration.
I think the guide should be updated to reflect the config based on the driver instead... when you run yum update ect it will break neutron until you re-edit the systemd files.

I confirmed that the debian packaged install is set up this new way and moved the settings to the new location and finally made some progress. After clearing out the stuck "binding failed" from the database all the ports bind and my VM creates with a NIC and I can assign fixed and floating IPs. Now onto the next challenge: I can ping the virtual router (even from the internet on its public port!) but cannot reach the running instance on either IP (tried all the namespaces with ip netns exec... with both IPs but nothing). But I will create a new thread here unless someone has a quick answer.

I have gotten as far as setting up a controller/network and a compute node with keystone, glance, cinder and nova services, but have gotten stuck trying to set up a DVR configuration of Neutron/openvswitch. I had an early OpenStack setup a few years ago (Essex release) but so much has changed from that "primitive" system with nova-network that I am pretty much a novice, but I am particulatly interested in the DVR setup to eliminate the dependency on a single network node for future expansion. However I have spent a few days not making no progress at all. I have tried to follow the relevant guide at http://docs.openstack.org/liberty/networking-guide/scenario-dvr-ovs.html as close as possible but I have not been able to get anything to work. All my ports come up dead (DOWN state, and tagged 4095 in ovs-vsctl) when I set up the virtual router and I cannot launch any instances as they fail at the network port binding stage.

However this seems to be more than a problem with the settings in the configuration files. This was revealed when I turned on debug level logging. For some reason no matter what settings I try in ml2_conf.ini most of them are ignored--it doesn't matter how many services I stop and start or even rebooting the entire system (even completely wiping out the database and starting over with network config), ALL the settings in the [ml2] section and all the [ml2_type_*] sections are ignored and a set of default values are used. The real sticking point seems to be that mechanism_drivers is always an empty list and tenant_network_types is always just ['local']. As such nova refuses to start any instances on the networks I set up. Has anybody else seen this behaviour?
