2015-07-20 06:53:45 -0500 asked a question Unable to enable dhcp for Private networks - Mirantis openstack

Hi All,

We are facing an issue IP assignment for the launched instance.

For created network, network name space are getting created. Also we have verified that the connections between controller and compute nodes are proper.

But when we look in to /var/log/neutron/dhcp-agent.log

We are seeing an error as Unable to enable dhcp for 0aff4aa3-e393-499d-b3bc-5c90dd3655b1 (private network)

Output below
