<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Thats troubling... We are considering using DVR soon, and we have to restart neutron-openvswitch-agent and openstack-nova-compute periodically go get them to talk to rabbit again....<br>
<br>
Thanks,<br>
Kevin<br>

<p class="MsoNormal">Hi all,</p>
<p class="MsoNormal">During testing of Neutron upgrades, I have found that restarting the L3 agent in DVR mode is causing the VM network downtime for configured floating IP.</p>
<p class="MsoNormal">The lockdown is visible when pinging the VM from external network, 2-3 pings are lost.</p>
<p class="MsoNormal">The responsible place in code is:</p>
<p class="MsoNormal"><span style="color:black">DVR: destroy fip ns: fip-8223e12e-837b-49d4-9793-63603fccbc9f from (pid=156888) delete /opt/openstack/neutron/neutron/agent/l3/dvr_fip_ns.py:164</span></p>
<p class="MsoNormal"><span style="color:black"> </span></p>
<p class="MsoNormal"><span style="color:black">Can someone explain why the fip namespace is deleted? Can we workout the situation, when there is no downtime of VM access?</span></p>
