Hey folks,

I’ve been trying for a while now to install OpenStack using packstack-queens on several different devices, but installation keeps failing due to external networking dying after OVS creates the br-ex bridge. Once install completes/fails I can ping gw but can’t reach anything external until I restart network.service. I’ve tried the setup on three separate Intel i5 NUCs & a laptop (all with 16-32G RAM, 250GB+ disk) & keep running into the same error on all boxes. Oddly enough, installation works like a charm on KVM & even on AWS ec2, but not on bare metal. Would someone mind helping me out?

Here’s an outline of my latest attempt:

OS: CentOS 7.5, RAM: 32G, Disk: 250G
[root@controller ~]# uname -a
Linux controller.strugglestack.org 3.10.0-862.11.6.el7.x86_64 #1 SMP Tue Aug 14 21:49:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Latest error: 

````
ERROR : Error appeared during Puppet run: 192.168.1.172_compute.pp
