                    a disclaimer: I’m working on Ubuntu and Icehouse, so
                    you might have different behavior, based on your
                    distributions.  Also, I don’t have all the specifics
                    and flags you might need, but hopefully this can
                    point you in the right direction.  Also, also, the
                    design below accounts for some VLAN segregation, and
                    may be more complicated than what you need.</span></p>

                    you already have the eth devices created, and
                    assuming your routing is correct: I would create a
                    new bridge for each vlan with ovs-vsctl (say,
                    br-ex803 and br-ex805).  If you look at <a

                      target="_blank">
http://openvswitch.org/support/dist-docs/ovs-vsctl.8.txt</a> you can
                    find the syntax for add-br to create the bridge,
                    then add-port to bind it to the eth device.  You can
                    also use ovs-vsctl to set the trunks property on the
                    port, after it’s created, which you’ll need for the
                    vlan tagging.  Then, create a new physnet to match
                    each one of those (physnet3, physnet4, etc) and
                    include them in the bridge-mapping as
                    “physnet3:br-ex803”, or something similar, and
                    specify the VLANs as belonging to that particular
                    physnet in the network_vlan_ranges parameter, like
                    “…physnet3:803,physnet4:805”. </span></p>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">After
                    all that, you’ll need to update the neutron sql
                    database so the entry in the network segments table
                    will point to the correct physnet.  Search it by the
                    UUID of the network you’re creating, and update the
                    physical_network property to match “physnet3” or
                    whatever you create.  Then you can create a subnet
                    from that network, allocate from it, and it should
                    work.  You’ll also need to restart the
                    openvswitch-agent and the L3-agent, probably before
                    you create the subnet.</span></p>
