<p>Hello Mike,<o:p></o:p></p>
<p>Thanks a lot for replying. <br>
No, I am not aware about veths not surviving a reboot. Is it mentioned in any document of OpenStack?
<o:p></o:p></p>
<p>I have checked the Neutron services and they are absolutely fine after reboot. This problem is seen even when I kill/stop the network services and again try to start them.<o:p></o:p></p>
<p>Could you please tell me if there is any fix for this? <o:p></o:p></p>
<p>BR,<br>
Varun<o:p></o:p></p>

that all the right Neutron services came up and are healthy after your reboot?</span><o:p></o:p></p>
