Open Stack

flat_interface= can only be used with a nic that does not have an IP associated with it. My eth0 has an IP associated with it and I am trying to run single nic so setting it breaks network connectivity to the system.

If you have single node set up, you don't need to use multi_host=True.

Also looking at the network configuration output you have posted. The bridge for fixed IPs must be attached to any of the physical interfaces that you have, but it appears attached to non existent vnet0.

If you are using FlatDHCP you should set flat_interface in your nova.conf, to the interface where fixed IPs musto go.

You can try to install devstack (http://devstack.org/guides/single-machine.html), for quickly verifying basic setup configuration and then compare to your current config to see whats wrong. Devstack usually works out of the box.
