<p class="MsoNormal">I have a system which is happily using vxlan type driver on icehouse<br>
on ml2 / ovs.<br>
<br>
I would now like to take on of the physical interfaces (eth1) and make<br>
it available in a 'tap' to a specific instance. Imagine running<br>
'snort' here.<br>
<br>
So i added the 'type_driver' flat:<br>
[ml2]<br>
type_drivers = vxlan,flat,local<br>
tenant_network_types = vxlan<br>
mechanism_drivers = openvswitch<br>
<br>
I added the bridge_mapping in ovs (this i'm not sure of given the<br>
tunnel_type=vxlan?)<br>
[ovs]<br>
tenant_network_type = vxlan<br>
tunnel_type = vxlan<br>
tunnel_id_ranges = 1:1000<br>
integration_bridge = br-int<br>
tunnel_bridge = br-tun<br>
local_ip = 172.16.100.2<br>
bridge_mappings = physnet1:br-ex,eth1:br-eth1,eth3:br-eth3<br>
enable_tunneling=True<br>
<br>
I ran<br>
ovs-vsctl add-br br-eth1<br>
ovs-vsctl add-port br-eth1 eth1<br>
<br>
and I ran:<br>
neutron net-create --shared --provider:network_type=flat<br>
--provider:physical_network=br-eth1 eth1<br>
<br>
so far so good.<br>
But i cannot get an instance to bind to this network. I've tried<br>
manually creating a port and using --nic port-id=, i've tried letting<br>
it add it. But i get Unexpected vif_type=binding_failed no matter what<br>
i do.<br>
<br>
In nova.conf I have<br>
libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver<br>
<br>
and i have port security disable fwiw.<br>
<br>
Do someone have a recipe they want to share for this? Obviously this<br>
works best on an 'all-in-one' which is what I have. Is someone else<br>
out there having an instance directly bound to a physical port via a<br>
bridge?<o:p></o:p></p>
