Hi Gary!

Openstack-nova-network ran only on the controller initially (this is 
how packstack set it up). I did try to set up more IPs in the answers 
file afterwards, but I got this:
"Parameter CONFIG_NOVA_NETWORK_HOST failed validation: Given host is 
not in IP address format:,,"
I take it it doesn't like comma separated stuff (though it worked for 
the COMPUTE hosts).

I have installed and started openstack-nova-network manually on the 
other machines, but it did not help in any way.
