Answer by slogan-r for I am trying to run an all-in-one using stack.sh with the latest (folsom3 and master) branches of Quantum on KVM but the gateway interface does not get created and as a result VM's do not get an IP. I've updated the install to include the steps mentioned here http://wiki.openstack.org/RunningQuantumV2Api (http://wiki.openstack.org/RunningQuan...) and here http://wiki.openstack.org/QuantumDevstack (http://wiki.openstack.org/QuantumDevs...) but never get a gateway interface after creating a network and subnet and spinning up a VM. This is what ovs-vsctl displays (after creating a network and subnet and spinning up a VM: stack@esg-dell-c4-s11:~/devstack$ sudo ovs-vsctl show 5dab4e1c-89c4-421e-a737-03b338eddc1a Bridge br-int Port patch-tun Interface patch-tun type: patch options: {peer=patch-int} Port "tap73f2ee73-79" tag: 1 Interface "tap73f2ee73-79" type: internal Port "tapd425d955-15" tag: 2 Interface "tapd425d955-15" type: internal Port br-int Interface br-int type: internal Port "tapc46b72b3-b3" tag: 2 Interface "tapc46b72b3-b3" Bridge br-tun Port patch-int Interface patch-int type: patch options: {peer=patch-tun} Port br-tun Interface br-tun type: internal ovs_version: "1.4.0+build0" Are there any additional steps that need to be run to make this work with the V2 Quantum API?

See the referenced bug report. ENABLED_SERVICES is one I copied from an earlier post you made on this thread, and from the devstack logs (attached to the bug), it sure looks like it is trying to start it. + screen -S stack -p q-agt -X stuff 'sudo python /opt/stack/quantum/quantum/plugins/openvswitch/agent/ovs_quantum_agent.py --config-file /etc/quantum/quantum.conf --config-file /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini^M' + screen_it q-dhcp 'sudo python /opt/stack/quantum/bin/quantum-dhcp-agent --config-file /etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini' ++ echo -ne '\015' + NL=$'\r' + is_service_enabled q-dhcp + services=q-dhcp + for service in '${services}' + [[ ,g-api,g-reg,key,n-api,n-cpu,n-sch,n-vnc,mysql,rabbit,openstackx,q-svc,quantum,q-agt,n-cpu,q-dhcp, =~ ,q-dhcp, ]] + return 0 + screen_rc q-dhcp 'sudo python /opt/stack/quantum/bin/quantum-dhcp-agent --config-file /etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini' + SCREENRC=/opt/stack/devstack/stack-screenrc + [[ ! -e /opt/stack/devstack/stack-screenrc ]] + grep q-dhcp /opt/stack/devstack/stack-screenrc + screen -S stack -X screen -t q-dhcp + sleep 1.5 + [[ -n '' ]] + screen -S stack -p q-dhcp -X stuff 'sudo python /opt/stack/quantum/bin/quantum-dhcp-agent --config-file /etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini^M' + NOVA_CONF_DIR=/etc/nova + [[ ! -d /etc/nova ]] ++ whoami
