<p class="MsoNormal"><span style="color:#1F497D">I followed the OpenStack icehouse installation guide to successfully install a five node system, one control node, one neutron and three compute nodes. Inside of the instance, I can ping other instances’ virtual
IP address and outside internet fine. Recently, we decided to move all the nodes to a lab. So, I powered down the five nodes before the move and powered up them afterward. All the physical network connections were exactly the same as they were before the move.
But, I can not even ping other instance after the five nodes up again. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I typed “route –n” inside of the instance, no any IP is shown. What’s wrong? Please help how I can get the instance networking back.<o:p></o:p></span></p>
