<div dir="ltr">Hello.<div><br></div><div>I'm looking for the way of LinuxBridge setup for openstack neutron networking instead of ML2 VLAN/VXLAN/GRE like your reason, and you seems successfully deployed the environment. </div><div><br></div><div>Could you give me any advice for the deployment?</div><div><br></div><div>I'm now deploying openstack 3 nodes (actually, I attached another compute, so my current deployment setup is 4nodes, i.e., 1 controller, 1 network, and 2 computes) by following the openstack installation guide, <a href="http://docs.openstack.org/kilo/install-guide/install/yum/content/neutron-controller-node.html">http://docs.openstack.org/kilo/install-guide/install/yum/content/neutron-controller-node.html</a>. I think several options in /etc/nova/nova.conf, /etc/neutron/plugins/ml2/ml2_conf.ini and /etc/neutron/neutron.conf should be modifed properly in order to use LinuxBridge instead of OVS. </div><div><br></div><div>Here are the lists what I know to modify:</div><div><br></div><div>1. /etc/neutron/neutron.conf on controller</div><div>core_plugin = ml2 (I think this should be modified but I don't know what parameter indicates Linux Bridge Agent Plugin)</div><div><br></div><div>2. /etc/neutron/plugins/ml2/ml2_conf.ini on controller</div><div>Do I still need to modify this file? I'm confused, because the file name is 'ml2', which is for ml2 plugin not for 'linux bridge'... And, I wonder the lists should be modified.</div><div><br></div><div>Thank you in advance!</div><div><br></div><div>Regards</div><div><br></div><div>Byeong-Gi KIM</div><div><br></div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2015-04-21 7:19 GMT+09:00 Martinx - ジェームズ <span dir="ltr"><<a href="mailto:thiagocmartinsc@gmail.com" target="_blank">thiagocmartinsc@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">Hi James!</div><div class="gmail_quote"><br></div><div class="gmail_quote"><span class="">On 20 April 2015 at 18:16, James Denton <span dir="ltr"><<a href="mailto:james.denton@rackspace.com" target="_blank">james.denton@rackspace.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div style="word-wrap:break-word">Hi Thiago,<div><br></div><div>VXLAN requires an IP address on each host from which to build the overlay mesh between hosts.
