Just yesterday I spend 7 hours debugging DHCP - it was misplaced space
in dhcp_agent.ini file.
One more place to see what happens is /var/log/upstart/neutron* logs
where all stdout/err output of staring daemons is placed (for ubuntu -
suse/centos are differ).

Hi,
I have a multi-node installation of OpenStack Havana, one controller
node, one network node and at the moment only one compute node.
When creating a VM no IP is assigned by DHCP. It seems to be a problem
with the openvswitch plugin on the controller node, it fails to start.
I also get a lot of error messages in my logs (controller node):
