I have a dual node (Controller and Compute) OpenStack setup, working fine. But i want to configure quantum for NaaS. I follow all steps of quantum administrator guide, and installed it in the controller-node.

<div><br></div><div>Hi Alisson,</div><div><br></div><div>This is correct. OVS replaces the linux bridge as the virtual switch. It must run on all compute nodes, as well as as any nodes running nova-compute, if you are using using Quantum in a way that requires some of the additional data plane services provided by nova-network (e.g., DHCP, L3 NAT gateway). </div>
<div><br></div><div>Since you've gotten this far, I'm guessing you're already following the OVS plugin directions at: <a href="http://openvswitch.org/openstack/documentation/">http://openvswitch.org/openstack/documentation/</a></div>

<div><br></div><div>I will go over the docs and try to make it more clear about what nodes require OVS to be installed. Best,</div><div><br></div><div>Dan</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
