Hi guys,

I have been experimenting with the enable-dvr option in neutron-api. I cannot find a clear guide on how to configure this. However I have ran into some issues trying to figure out the configuration to enable dvr.

This is where juju stops: unit-neutron-openvswitch-1: 11:45:35 INFO unit.neutron-openvswitch/1.juju-log Creating bridge br-int unit-neutron-openvswitch-1: 11:45:35 INFO unit.neutron-openvswitch/1.juju-log Creating bridge br-ex unit-neutron-openvswitch-1: 11:45:36 DEBUG unit.neutron-openvswitch/1.juju-log Replacing iface 'eno1' with bond master 'os' unit-neutron-openvswitch-1: 11:45:36 DEBUG unit.neutron-openvswitch/1.juju-log Replacing iface 'eno2' with bond master 'os' unit-neutron-openvswitch-1: 11:45:36 DEBUG unit.neutron-openvswitch/1.juju-log Replacing iface 'eno3' with bond master 'stor' unit-neutron-openvswitch-1: 11:45:36 DEBUG unit.neutron-openvswitch/1.juju-log Replacing iface 'eno4' with bond master 'stor' unit-neutron-openvswitch-1: 11:45:37 INFO unit.neutron-openvswitch/1.juju-log Creating bridge br-data unit-neutron-openvswitch-1: 11:45:37 DEBUG unit.neutron-openvswitch/1.juju-log Interface os.392 is not a Linux bridge unit-neutron-openvswitch-1: 11:45:37 INFO unit.neutron-openvswitch/1.juju-log Adding port os.392 to bridge br-data unit-neutron-openvswitch-1: 11:45:37 DEBUG unit.neutron-openvswitch/1.config-changed Failed to restart os-charm-phy-nic-mtu.service: Unit os-charm-phy-nic-mtu.service not found.

That restart failure is a bit of a red-herring (and needs tidying) - it relates to a tactical fix for MTU configuration of interfaces in Trusty (for which we are due to drop support this year). snip [...]

Any help appreciated :)

The current release of OpenStack Charms still requires use of the neutron-gateway charm for snat traffic routing; that said we have gateway-less features currently in development which allow the agents managed by the neutron-openvswitch charm to be configured for snat routing as well, removing the need for the gateway. Here is a bundle based on the openstack-base bundle which I've been testing with: http://paste.ubuntu.com/p/nsx86snZpb/ Obviously the network space binding, storage configuration and maas tags are all specific to my testing environment - but it demonstrates how to get this working.
