You should find your adapter's configuration in /etc/sysconfig/network-scripts/ifcfg-ethX where X is the number of the interface you want to configure. If you only have one interface, then X = 0.

It would be helpful if you provided some details about your Openstack deployment. How many nodes are you trying to setup?

Assuming your trying to run Packstack in an "all in one" configuration, I would recommend following these instructions

same error here with: packstack --neutron-ovs-tenant-network-type=gre --install-host=192.168.0.1,192.168.0.2,192.168.0.3

eth0 is my admin interface with ip addr 192.168.0.1 (my controller) eth1 is one the same network, but no address on it

I try to install rdo icehouse openstack release.

Seems puppet try to configure iptables with an wrong address
