Thanks, Mark. OK, maybe I should say that I am past my first attempt, and am on to something a little more ambitious. Following recipes like yours, and also ones from Sergey Kraynev, Salvatore Orlando, and Ian Choi, I am able to get DevStack to create an OpenStack installation with Neutron that works --- as long as I do not attempt any communication between the outside world and the VMs that I can create with that OpenStack. What I want is a local.conf or localrc that will cause DevStack to do a single-node install of OpenStack with Neutron (I am not picky about plugin or driver) on a host with one NIC, with the following property. When I use that OpenStack to create a VM, and assign a floating IP to that VM, IP communication between that VM and machines in the wider world is possible. By "the wider world" I mean the part of the internet with which the host can communicate, whatever that may be. For example, if the host is a machine on the public internet, the wider world would be everything reachable on the public internet. Another example was in my original question: the host is a lab machine on a 10... network (it has more than one subnet, connected by real layer 3 routers), and the wider world in that case is all the other machines in that lab. As best I can tell, this requires some correspondence between (a) the settings of FLOATING_RANGE and PUBLIC_NETWORK_GATEWAY that I put in localrc and (b) the pre-DevStack IP address, netmask, and gateway of the host. Perhaps I am confused about something critical here. I do not understand why nobody talks about this. Is it because everybody is using the same Vagrant/VBox script and that happens to correspond with the DevStack defaults? Thanks, Mike
