Using interface name does not work with dynamic bridging

[AshleyLai]

In neutron-openvswitch-cplane charm, the mgmt-int and data-interface config options expect a network interface name. This is an issue with juju version juju-2.1-rc1 as it creates the bridge dynamically. The network bridge is created when there is a container.

When I specify br-eth0 it complaints that br-eth0 does not exist. However if I specify eth0 it failed with the following error.

cplane-controller charm also uses interface name for multicast-intf and multicast-srv-intf.

Hi Ashley,

This sounds like a compatibility problem with RC1. The behavior of a system should not change in a . (dot) release. I will defer to David on how to handle this.

I suggest you try it with the verified release version of juju. I believe the customer (PCCW) is using juju 2.0.

Hi Ashley,

If you are using the MAAS then the best option is to renamed the interfaces of the nodes in the MAAS GUI to eth0 and eth1. This is what we did in our setup.

Thanks

Amar
