Hello all,

I'm attempting to migrate my Havana test cluster over to the ML2 plugin from the monolithic OVS plugin. I had been successfully using OVS in VLAN mode. I reset my core_plugin and service_plugins in neutron.conf, I followed the steps to reinitialize my Neutron databases, to upgrade their heads with neutron-db-manage, and transpose my configuration from /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini to /etc/neutron/plugins/ml2/ml2_conf.ini.  My neutron agent-list seems happy:

# neutron agent-list

+--------------------------------------+--------------------+------------------------+-------+----------------+

My ml2_conf.ini looks like this:

[ml2]
type_drivers = vlan
tenant_network_types = vlan
mechanism_drivers = openvswitch
[ml2_type_flat]

[ml2_type_vlan]
network_vlan_ranges = physnet1:4:4,physnet1:101:104,physnet2:2:2
[ml2_type_gre]

[ml2_type_vxlan]

[database]
sql_connection = postgresql://neutron@dbhost/ovs_neutron
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
[ovs]
bridge_mappings = physnet1:br-eth1,physnet2:br-ex

This is not reflected though when I do a neutron agent-show on that host:

Shouldn't I be seeing VLAN configuration info there instead of empty tunneling info?

The net effect of all this is my VMs can't connect to their OVS switches and complain thusly in /var/log/neutron/server.log:

Does ML2 even work for VLAN in Havana? The Havana ML2 documentation[1] does not list VLAN as a configuration option. I'm running all my nodes on CentOS 6.5 installing from the RDO Havana repo.
