Jay reached out to me and in some discussion it seems like the
following is occurring:

* Ramdisk is loading from tftp_server
* Conductor is not able to reach the 10.0.0.0/24 subnet where the
ironic-python-agent is running
* There appears to be a lack of a route inside the CI host that the
conductor is operating on telling the host kernel to direct packets
for IPA to the neutron router. Ramdisk loading would still work if
egress traffic is being NAT translated, but ingress traffic would
appear like this, ironic being unable to send packets because the
conductor is communicating from the context of the CI host, and any
namespaces created by neutron may not be directly reachable.
