I want to use DevStack to install and configure OpenStack with Neutron,
into a VM in an OpenStack undercloud. I looked at
https://wiki.openstack.org/wiki/NeutronDevstack and tried that, and
failed. Looking deeper, I see there are very important additional details
to pay attention to: flat networking vs. more complex, with attention to
address ranges all around. Is there a short sharp description of the
DevStack defaults in those regards? Does anybody have a simple example
that works, with comments about the networking in the undercloud?
I have three underclouds available. Undercloud 9 is built on bare metal
machines in the 10.0.0.0/8 address space, but does not in any way use
addresses in the 10.0.0.0/15 space; this is Havana with Neutron doing
non-flat networking. Undercloud 15 is built on a single bare metal
machine in the 220.127.116.11/8 address space; this is Icehouse as of a few weeks
ago, with nova networking giving VMs static IP addresses in the
10.0.0.0/16 space (obviously I can add networks and subnets inside this
undercloud). Undercloud 22 is built on a single bare metal machine in the
18.104.22.168/8 address space; this is Grizzly with Quantum doing flat
