Open Stack

Hi,

my first action would be debug mode for neutron logs and then review  
all of the logs (server, dhcp-agent, linuxbridgeagent, etc.). At least  
one of them should also report errors, maybe they point you to the  
right direction.

Have you checked 'openstack network agent list'? Are all agents up?

Regards
