Have tried several times over to launch an instance, in each and every 
case it is left in an ERROR state. Feel a lot of my issue is lack of 
concise documentation as well as being very very green with openstack.

looking through the nova/network.log I see the following error for an 
instance I just tried to launch

failed to bind listening socket for 10.0.0.1: Address already in use

10.0.0.1 was assigned to br100 by nova, even more confused now ;)
