[Rdo-list] OVS bridge not coming up at boot on centos7

[Arif Ali]

Hi chaps,

I have been testing rdo-openstack for the last few months, and finally got
the basic stuff working yesterday with all the necessary core bits, :)

The one issue I have found with the system at the moment is that when I
reboot any of the machines in the cluster, whether it's the controller or
the nova node, the OVSBridge ports do not acquire an IP address.

I then go onto the machine via IPMI SOL, and restart the networking through
"systemctl restart network.service"

So an extracts of commands below

If someone can shed any light, hat would be great
