From the OpenStack Networking Guide

The suggested configuration for /etc/quantum/plugins/linuxbridge/linuxbridge_config.ini to implement a single public network with multiple VLAN tenant networks is:

tenant_network_type = vlan
network_vlan_ranges = physnet2:100:110

physical_interface_mappings: physnet2:eth1

However it is not clear from this how the external network is defined. If amend the bridge section:

physical_interface_mappings: physnet2:eth1,physnet3:eth1

This raises an execption in /var/log/quantum/server.log on startup. If I amend the vlan section:

tenant_network_type = vlan
network_vlan_ranges = physnet2:100:110,physnet1

This works, but it's not clear if I can set that physical network as having no VLAN range (I can still create a network with a --provider:network_type vlan...

Furthermore, I cannot add multiple physical_interface_mapping entries. E.g.

physical_interface_mappings: physnet2:eth1,physnet3:eth2

Just makes everything unhappy.

Are you making a distinction between the ":" and "=" as the key/value separator?

That must be a doc bug. It should be:

physical_interface_mappings = physnet2:eth1

Or for multiple mappings it is a comma separated list like:

physical_interface_mappings = physnet2:eth1,physnet3:eth2

The key-value separator in the main value is :
