msg: cannot change to directory '/opt/neutron_master/etc/nova': path does not exist
this should be resolved with the merge of PR: https://github.com/rcbops/ansible-lxc-rpc/pull/194. You may need to remove the "nova_*" directory in /opt and rerun but with the change it should be good to go.
Offending code is in https://github.com/rcbops/ansible-lxc-rpc/blob/master/rpc_deployment/roles/openstack_common/tasks/main.yml#L19-L24
This is possibly related to the change to make neutron use repo_packages: https://github.com/rcbops/ansible-lxc-rpc/pull/187
