Hi Jake,

most of the info here have been shamelessly copied from
http://devstack.org/guides/single-machine.html
In general devstack.org has plenty of information to understand how it
deploys openstack and troubleshoot issues.

Should be configured to a range not used on the local network, i.e.
192.168.1.224/27. This configures IP addresses ending in 225-254 to be used

Not sure where it is used.  (Neutron uses a variable called
PUBLIC_NETWORK_GATEWAY for a very similar purpose)
