<p class="MsoNormal"><span style="color:#1F497D">I was hoping you could shed some light on what I’m seeing. I was doing some comparison between my controller/compute node and another compute node – using “nova-manage config list”. I noticed some configuration
entries that look like they are leftovers from Nova Network. When I created our Openstack cluster originally I used packstack to start and then converted from Nova Network to Quantum. Is it possible that some of these leftover config entries are causing conflicts
with Quantum Networking? Some of the questionable entries are:<o:p></o:p></span></p>

Sorry to hear that. Hopefully we will be able to help out.<br>

<p class="MsoNormal">Which of the RHEL Openstack Folsum Quantum implementations are supported (FLAT, FLAT DHCP, VLAN, GRE)?<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif""><br>
GRE is not supported. This is due to the fact that there are some missing parts from the current kernel.<br>
<br>
<br>
<o:p></o:p></span></p>
<p class="MsoNormal">Which of those implementations support the Openstack Metadata Service?<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif""><br>
In Folsom a VM can only access the metadata service if the L3 agent is running. <br>
<br>
In Grizzly this can be done via the L3 agent or the DHCP agent (there may be cases where one would not want to run the L3 agent).<br>
<br>
Please note that due to the fact that there is no namespace support in RHEL this support does not work when there are networks with overlapping IP ranges.<br>
<br>
<br>
<br>
<o:p></o:p></span></p>
<p class="MsoNormal">Can Metadata be supported without using the Quantum L3 agent, such as in the FLAT/FLATDHCP models?<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif""><br>
Only with Grizzly.<br>
<br>

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Which Openstack Quantum Use Cases are supported?<o:p></o:p></p>
<p class="MsoNormal"> Single Flat Network <o:p></o:p></p>
