<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a small Openstack kolla-ansible deployment running on a bond 2x 25Gbits/sec network and jumbo frames MTU 9000. I was trying to setup kolla-ansible to be aware of my physical network configuration but I could not find any document
related to this.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also tried to make this changes manually modifying neutron.conf and ml2_conf.ini files on control and compute nodes (<a href="https://docs.openstack.org/neutron/pike/admin/config-mtu.html">https://docs.openstack.org/neutron/pike/admin/config-mtu.html</a>)
and rebooted the neutron containers but new vms still has MTU 1450.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Questions:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone knows how to configure kolla-ansible to do what I want?<o:p></o:p></p>
<p class="MsoNormal">Does anyone has a tip about how to configure MTU 9000 on a Opestack kolla-ansible deployment?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much<o:p></o:p></p>
