I have a working icehouse openstack environment with neutron ovs and gre tunnels. The environment was set using maas and juju (deployed openstack charms).
Would like to configure opencontrail instead of ovs in neutron and I am looking for assistance here.
The environment is juju controlled hence manually editing the config files e.g. neutron.conf is not a choice.
I see opencontrail related chrams in juju charm store, but there ins't much details including what relations it may require.
