Some added color... The interfaces are defined in Quantum and they have MAC
addresses generated... They just don't make it into the nova-compute
generated libvirt.xml. There seems to be other stuff missing to, like the
bridge name. Is that supposed to be blank?

I'm installing nova and quantum in an environment where L3 routing and
DHCP are handled by other devices on a provider network for specific VLANs.
I don't want the service of the quantum-l3 or quantum-dhcp agents, as there
services are handled by external devices.
Nova compute is setup to use:
libvirt_type=kvm
libvirt_ovs_bridge=br-int
libvirt_vif_type=ethernet
libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver
libvirt_use_virtio_for_bridges=True
I am using the OVS plugin for Quantum Folsom. Here is the OVS section of
my ovs_quantum_plugin.ini file.
[OVS]
tenant_network_type = vlan
network_vlan_ranges = physnet1:1:4,physnet1:60:64
bridge_mappings = physnet1:br-eth2
The output of ovs-vsctl show looks like the following:
efbab661-98dd-46b3-b5c1-e234c3afac8e
Bridge br-eth2
Port phy-br-eth2
Interface phy-br-eth2
Port br-eth2
Interface br-eth2
type: internal
Port eth2
Interface eth2
Bridge br-int
Port br-int
Interface br-int
type: internal
Port int-br-eth2
Interface int-br-eth2
ovs_version: 1.4.0+build0
Interface eth2 is a VLAN trunk. I can manually create ports in OVS and
then add link and ip address for VLANs 1-4,60-64 verifying connectivity.
I run the following commands to setup the logical network:
quantum net-create VLAN1 --router:external=True --shared
--provider:network_type=vlan --provider:physical_network=physnet1
--provider:segmentation_id=1
quantum net-create VLAN2 --router:external=True --shared
--provider:network_type=vlan --provider:physical_network=physnet1
--provider:segmentation_id=2
quantum net-create VLAN3 --router:external=True --shared
--provider:network_type=vlan --provider:physical_network=physnet1
--provider:segmentation_id=3
quantum net-create VLAN4 --router:external=True --shared
--provider:network_type=vlan --provider:physical_network=physnet1 --
provider:segmentation_id=4
quantum net-list show
