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?

Rohit I looked at all the quantum logs and could not find any errors and none of the tap interfaces get IP addresses assigned. I ran the folsom2 version of Quantum on this same server and it worked fine and created tap and gateway devices (and the gateway was assigned an IP). This is what the tap interface looks like after creating a network and subnet. tap9618cae3-7e Link encap:Ethernet HWaddr 36:13:13:d4:71:b5 inet6 addr: fe80::3413:13ff:fed4:71b5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:153 errors:0 dropped:0 overruns:0 frame:0 TX packets:60 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:11664 (11.6 KB) TX bytes:7982 (7.9 KB) Is there anything else I can look at?
