 If using Vagrant, follow the steps in :ref:`development-vagrant` to prepare
 your environment for use with Vagrant and bring up a Vagrant VM.
 
+If not using Vagrant, the default development configuration expects the
+presence of a bridge interface on the OpenStack controller host to carry
+control plane traffic.  The bridge should be named ``breth1`` with a single
+port ``eth1``, and an IP address of ``192.168.33.3/24``.  This can be modified
+by editing
+``config/src/kayobe-config/etc/kayobe/inventory/group_vars/controllers/network-interfaces``.
+Alternatively, this can be added using the following commands::
+
+    sudo ip l add breth1 type bridge
+    sudo ip l set breth1 up
+    sudo ip a add 192.168.33.3/24 dev breth1
+    sudo ip l add eth1 type dummy
