Hi, I have a single node (all-in-one), 2 nic, (am willing to turn-off the 2nd nic just to easily make it work), and a flat network. (Flat meaning I have ONLY been assigned 10 static IPs) specifically to (gateway

MY PROBLEM: Devstack single node configs has a fixed & floating range IPs. My setup restriction is on a single shared network. So, I'm really limited on those 10 IPs.

MY SETUP: I'm using Ubuntu 12.04 + Devstack. Successfully installed Devsack w/ all 21 running screens. And got past that Horizon 'product_id' bug. But on launching an instance I always get an 'Error' status which I cannot find the problem to. But I think Neutron/Quantum might be the problem.

"error: Zero fixed ips could be found."

My localrc

quantum disable_service s-proxy

Also, might it be easier to install Openstack from scratch and not use devstack?

Thank you.

Yes - I would recommend that you perform a manual install using the Install Guides available at - Devstack will continue to get in the way of what you want to do, so better to do it properly, and it doesn't really take that long.

There is also a helpful networking guide ( ) that contains a number of useful scenarios. I recommend checking the one on Provider Networks.
