Re: [openstack-dev] [Neutron][DevStack] How to increase developer usage of Neutron
Through my experience, RDO should be the most reliable way to do the deployment. Also, there're some more detailed installation scripts, like https://github.com/ChaimaGhribi/OpenStack-Icehouse-Installation/blob/master/OpenStack-Icehouse-Installation.rst . Still, I think, as a developer, it would be nice to have a deeper understanding of the underlay implementation.

However, I'm pretty sure it's only a single node all in one setup. At least, I created only one VM to run it on and I don't think DevStack has created multiple nested VMs inside of the one I create to run DevStack. I haven't gotten around to figuring out how to setup a full multi-node DevStack setup with separate compute nodes and network nodes and GRE/VXLAN tunnels. There are multi-node instructions on that wiki page but I haven't tried following them. If someone has a Vagrant file that creates a full multi- node Neutron devstack complete with GRE/VXLAN tunnels it would be great if they could add it to that wiki page. ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

A working concrete recipe for a single-node install would be great. https://wiki.openstack.org/wiki/NeutronDevstack is far from a concrete recipe, leaving many blanks to be filled in by the reader. My problem is that as a non-expert in the relevant networking arcana, Neutron implementation, and DevStack configuration options, it is not entirely obvious how to fill in the blanks. For starters, http://docs.openstack.org/admin-guide-cloud/content/network-connectivity.html speaks of four networks and, appropriately for a general page like that, does not relate them to NICs. But at the start of the day, I need to know how many NICs to put on my host VM (the one in which I will run DevStack to install OpenStack), how to configure them in the host VM's operating system, and how to tell DevStack whatever details it needs and cannot figure out on its own (I am not even clear on what that set is). I need to know how to derive the fixed and floating IP address ranges from the networking context of my host VM. A recipe that requires more than one NIC on my host VM can be problematic in some situations, which is why I suggested starting with a recipe for a host with a single NIC. I am not using Xen in my undercloud. I suspect many developers are not using Xen. I did not even know it was possible to install OpenStack inside a Xen VM; does that still work? I was hoping for a working concrete recipe that does not depend on the undercloud, rather something that works in a vanilla context that can easily be established with whatever undercloud a given developer is using.
