Hello, I am attempting to use Packstack with an answer file to install Openstack on two nodes -- a controller/network node and a compute node. I installed Packstack for Stein new today.

When I run packstack with the answer file, it gets to the step: "Preparing Neutron API entries" and then errors out. The error reads: ERROR : "Couldn't detect ipaddress of interface ens2f1 on node 10.57.38.123"

The controller node management IP is 10.57.38.123 (on bond0). I am trying to use ens2f1 for the OVN tunnel. It's IP address is 10.57.37.123 (verified on the server).

I will post the networking part of the answer file and the setup log with failure below. The entire answer file won't post correctly.
