Open Stack

Hello all!

Firstly, thanks to everyone who has helped me get OS up and running :)

Now that I have a working FlatDHCP up and running it is time to expand 
outwards and dive into configuring VLAN as per 
http://docs.openstack.org/diablo/openstack-compute/admin/content/configuring-vlan-networking.html.  
After following the document listed I am left with a broken nova-network:

anyone have some insight? I tried to update each fixed_range with a host 
using nova-manage :

nova-manage network modify --fixed_range=10.200.2.0/24 
--host=nuvola.potsdam.edu
nova-manage network modify --fixed_range=10.200.9.0/24 
--host=nuvola.potsdam.edu

but the iptables restore error persists.
