<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext">In my setup, on both gateway and compute node, I use NIC p3p1 as internal traffic port, it¡¯s added into br-int.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext">I do tcpdump on compute node p3p1 port, find the frame sending out the port does have vlan tag, but when I do tcpdump on gateway node (receiver) p3p1 port,
I see the frame has no vlan tag on it. Somehow the OS eats the vlan tag of incoming frame from p3p1 port. That causes openvswitch on gateway node can't handle these abnormal frames. Test shows the same results for traffic from gateway node to compute node.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext">What I have done to fix this:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext">On both gateway and compute node, I add a vlan interface p3p1.195 (vlan 195 is actually not used). After this, the OS can handle vlan tagging on frames
received from p3p1 correctly. It seems the NIC does not know how to handle vlan tags unless there¡¯s at least one vlan configured on the port.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:windowtext">It can be a OS bug of just a configuration problem. I don't know if there¡¯s a better way to activate vlan handling on the port without actually creating
a vlan interface on it. ? Any ideas ?<o:p></o:p></span></p>

When the process 2320 is killed the VM receives its address.<br>
<br>
So in short we have some hardening to do :)<br>
With patches for the issues below and shutting down the aforementioned process I have a VM getting a address.<br>
<br>
Thanks<br>

<p class="MsoNormal">Hi,<br>
I have found a few problems and hopefully one or more may be related to the case that you have experienced:<br>
1. When using OVS it is important you run the service ovs-quantum-cleanup when the host boots. This is due to the fact that OVS will store all tap device. This causes havoc when restarting hosts (in particular ones that have dhcp and l3 agents). So please make
sure you have run "chkconfig quantum-ovs-cleanup on" on all hosts that are running the OVS. You can verify if this is the case by checking of the DHCP agent has created an IP address on the host. [Please note that we have a problem here - in the file /etc/init.d/quantum-ovs-cleanup
"--config-file /usr/share/$proj/$proj-dist.conf" needs to be removed].<br>
2. Which dnsmasq version are you using? If this is 2.48 then there is a problem with the DHCP agent running. We are in the process of resolving this. If you make use of a version with tag support then this will work.<br>
3. The quantum client needs to be updated to support the security groups.<br>
Hopefully we will have solutions for all of the above ASAP.<br>
Thanks<br>
Gary<br>

One more question - on the network node, did you run quantum-dhcp-setup?<br>
I am nearly ready with my setup. Hopefully I'll have a reproduction or some additional questions.<br>

<p class="MsoNormal">Hi,<br>
Can you also please check that firewall_driver = quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver is configured in plugin.ini file.And security_group_api = quantum is set in nova.conf<br>
Thanks<br>

When using the OVS there are a number of devices. Would it be possible that you try and capture on each device so that we can try and see where the packet is discarded.<br>
<br>
I will have a setup ready in about an hour.<br>

<p class="MsoNormal">Hi Kimi,<br>
Thanks for the mail. Please see the inline comments below. Please note that at the moment we do not have packstack support for Quantum so there is a little manual plumbing that needs to be done (not sure if you have done this already).<br>
On the host where the quantum service is running you need to run quantum-server-setup and on the compute nodes you need to run quantum-host-setup (please note that the relevant keystone credentials need to be set too).<br>
Thanks<br>
Gary<br>

Please note that RHEL currently does not support namespaces so there are a number of limitations. We are addressing this at the moment. If namespaces are not used then it is suggested that one does not run the DHCP agent and the L3 agent on the same host. The
reason for this is that there is no network isolation.<br>
