Hi Uwe When I initially started, my setup was on Ubuntu 14.04 (bare machines) 3 node OPenStack Icehouse architecture. The guide didnot say anything about installing dnsmasq. Then, the VMs were not getting IPs. I then installed dnsmasq (sudo apt-get install dnsmasq) in Neutron node and the issue was solved.
I think you should first try without installing it and everything works fine then its good. Or else install dnsmasq on Neutron node.
