<p class="MsoNormal">Hello All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been trying to duplicate this guide here mostly. <a href="https://developer.rackspace.com/blog/neutron-networking-vlan-provider-networks/">
https://developer.rackspace.com/blog/neutron-networking-vlan-provider-networks/</a> The provider network part is useful to me but the gre tunnels and and dhcp are not needed for us. We want to assign the addresses via a central build server rather than having
openstack manage it on a site to site basis.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The VLANs are trunked to the port of the management server and the compute/network node. The VLAN stuff is verified working through manual testing. When I tcpdump eth0 I also see lldp announcements showing the right information in regards
to vlans and so on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I run a standalone management server. I am running the network and compute node on the second server and I modified necessary settings using the installation guide for icehouse on docs.openstack.org. I then used some of the settings above
to create the OVS settings.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have one network card per chassis, a 10Gb Intel adapter.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">eth0 has no addressing<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a bridge called br-eth0 with the addressing from the management network assigned to it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here are my settings from /etc/neutron/plugin.ini (ml2_conf.ini). These are consistent across the management and compute/network host. Everything seems to be communicating with its databases fine.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have tried commenting out the [ml2] stuff and using just the [ovs] stuff to no success. 106 and 400 are the vlans I configure here and the network is labelled openstack. We have a third management network but traffic on that is all untagged.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here are the parameters set below currently.<o:p></o:p></p>

<p class="MsoNormal">[ovs]<o:p></o:p></p>

<p class="MsoNormal">Neutron net-list shows the networks created when I run the provider commands linked in the article above. I added a gateway to the address space though as the cirrus image wouldn’t launch without a gateway defined to the network range.<o:p></o:p></p>

<p class="MsoNormal">When I launch the vm build without networking the build succeeds and creates its own network port in each subnet even when not specifying the –nic and –net-id stuff with nova boot command . Neither respond to ping and when you login to
the vm via you get nowhere even if you assign address as the tagging applied is random. The web interface shows the port up and active in the subnet and the device owner is compute:None .<o:p></o:p></p>

<p class="MsoNormal">Is there some step I am missing in the plugin.ini (ml2_conf.ini) file that is stopping me from creating vms with network? It can’t be nova as the vm launches when no network is specified? I have had a second admin check my configuration
files and it followed the guide to a letter aside from the modified network settings we need to suit out setup which is why I am thinking this is where I have gone wrong.
