Hi.

I have strictly following the installation procedure for quantum as mentioned in the quide, I have created quantum user, binded to role and service in keystone and did the corresponding changes in nova.conf and quantum.conf file.

I am unable to create a network, when I am trying to create network , I am seein the following information from l3-agent.log file

This is a question, rather than a docbug, so should be asked as a Question in launchpad.

It seems that any of the Quantum Services is not running, do you have the following processes running? #ps -ef |grep quantum python /opt/stack/quantum/bin/quantum-server --config-file /etc/quantum/quantum.conf --config-file /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini python /opt/stack/quantum/bin/quantum-openvswitch-agent --config-file /etc/quantum/quantum.conf --config-file /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini python /opt/stack/quantum/bin/quantum-dhcp-agent --config-file /etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini python /opt/stack/quantum/bin/quantum-l3-agent --config-file /etc/quantum/quantum.conf --config-file=/etc/quantum/l3_agent.ini

Could you also verify in their respective logs is everything is ok. I also recommend to install another host using devstack: http://wiki.openstack.org/QuantumDevstack (http://wiki.openstack.org/QuantumDevs...) It will help you to verify all your configuration files.

well, the fact that we are getting an HTTP 404 error code and not a "connection refused" implies that quantum is running (or at least, some server is running on the IP + port you are specifying at the quantum server address.

Can you post the logs for quantum-server, and the l3_agent.ini (probably in /etc/quantum) used for the agent?
