[Openstack] Whole sections of ml2_conf.ini being ignored?

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 managed to do the backport today, so you should see the new version merge into the Liberty version in the next few days.

Thanks for the quick help. 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.

Looks like we (docs) never backported those fixes to the Liberty version of the guide. For some reason, the patch does not merge cleanly so I'm not sure when I'll get to it.

In Liberty, the L2 agent configuration moves from ml2_conf.ini to openvswitch_agent.ini for OVS and linuxbridge_agent.ini for Linux bridge.

Hi,
I have recently installed a small openstack setup using the Liberty release (from Debian Sid packaging). 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.
In the nova-compute.log:
2016-02-17 19:01:51.160 2556 ERROR nova.compute.manager [instance: 848c9525-3f48-4747-bbf1-d0d8bf52697b] PortBindingFailed: Binding failed for port bf1cde62-7ac6-47a8-8fb9-85ec524d02bd, please check neutron logs for more information.
In neutron-server.log:
2016-02-17 19:01:50.669 3224 ERROR neutron.plugins.ml2.managers [req-e6f1dbbd-d26c-456a-af6a-604c905dc194 b1ce670ebde640b0a0b159f01b18c04e ffbdd9d45cf84de0a204acfd0344ee6b - - -] Failed to bind port bf1cde62-7ac6-47a8-8fb9-85ec524d02bd on host hostserver-0001

I have tried using VXLAN as shown in the guide as well as VLAN but both do the same thing. 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? For what it's worth here is what I currently have in my ml2_conf.ini file:
[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types = vlan,gre,vxlan
mechanism_drivers = openvswitch,l2population
[ml2_type_flat]
flat_networks = public
[ml2_type_vlan]
network_vlan_ranges = vlans:3:63
[ml2_type_gre]
tunnel_id_ranges = 1000:1999
[ml2_type_vxlan]
vni_ranges = 2000:2999
vxlan_group = 239.1.1.1
[ovs]
local_ip = 10.37..3.254
bridge_mappings = public:br-out,vlans:br-ex
[agent]
l2_population = True
tunnel_types = vxlan,gre
enable_distributed_routing = True
arp_responder = True
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True
enable_ipset = True
and here is a sample of what appears in my logs:

examining the actual code it appears my settings are always ignored and non-functional defaults are used.
What am I missing? The problem persisted even after wiping the netowrk config and database and set up from scratch.
If anyone has an idea let me know--I can provide additional info if required.
Thanks!
