Openstack networking can be very frustrating, the guide you are following
is for quantum so you don't use nova.networking configurations.
1. download the cirros image in the tutorial , you can then login via vnc
without networking and rebuild a static network on that image for testing
Quantum is managing the dhcp so look at the dhcp logs to see if it even
received the request, I believe quantum still uses dnsmasq for managing
dhcp, tcpdump -i the bridge to see if you see where the request is going.
The guide you are using seems quite specialized, I would suggest comparing
with other guides, I use nova networking myself.
