Answer by eoghank 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?

Syd My VM's did get IP's assigned by the quantum agent and by disabling namespaces I was able to ping them (or by switching to the correct network namespace). I tried spinning up VM's with the default network and subnet that devstack creates as well and that worked fine. And this is what dhcp shows as running the 10.0.0.0/24 subnet: 3180 1 0 17:24 ? 00:00:00 dnsmasq --no-hosts --no-resolv --strict-order --bind-interfaces --interface=tap76a31515-4c --except-interface=lo --domain=openstacklocal --pid-file=/opt/stack/data/dhcp/87aca91f-e5e0-4149-86e1-a9d62ab31a35/pid - dhcp-hostsfile=/opt/stack/data/dhcp/87aca91f-e5e0-4149-86e1-a9d62ab31a35/host --dhcp-optsfile=/opt/stack/data/dhcp/87aca91f-e5e0-4149-86e1-a9d62ab31a35/opts --leasefile-ro --dhcp-range=set:tag0,10.0.0.0,static,120s Eoghan
