Thank you ! Another question: Last time I rebooted the Overcloud, and the 169.254.169.254 route was gone, is this normal ? It is supposed that for every reboot 169.254.169.254 route exists, right ? Maybe its OS image issue or something else ? *Best Regards！* *Chao Yan--------------**My twitter：Andy Yan @yanchao727 <https://twitter.com/yanchao727>* *My Weibo：http://weibo.com/herewearenow <http://weibo.com/herewearenow>--------------* 2014-10-24 0:36 GMT+08:00 Clint Byrum <clint at fewbar.com>: > Excerpts from 严超's message of 2014-10-23 01:08:09 -0700: > > Hi, All: > > I recently deployed an Overcloud machine using Undercloud.
