[hamzy@oscloud5 ~]$ lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.3.1611 (Core) Release: 7.3.1611 Codename: Core [stack@oscloud5 ~]$ uname -a Linux oscloud5.stglabs.ibm.com 3.10.0-514.16.1.el7.x86_64 #1 SMP Wed Apr 12 15:04:24 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Unfortunately, it seems that Environment setup for baremetal environment does not explain how to install the undercloud. There are three machines in this scenario:
| arch | use | portname1 | MAC1 | IP1 | portname2 | MAC2 | IP2 |
| x86_64 | undercloud | eno2 | 6c:ae:8b:29:2a:02 | 9.114.219.30 | eno4 | 6c:ae:8b:29:2a:04 | 9.114.118.98 |
| x86_64 | overcloud control | eth??? | 00:0a:f7:73:3c:c3 | 9.114.219.134 | eth??? | 6c:ae:8b:29:27:fa | 9.114.118.??? 13? |
| ppc64le | overcloud compute | enP3p5s0f2 | 00:90:fa:74:05:52 | 9.114.219.49 | enP3p5s0f3 | 00:90:fa:74:05:53 | 9.114.118.154 |
So, following Undercloud installation, I perform the following:
[hamzy@oscloud5 ~]$ sudo useradd stack
[hamzy@oscloud5 ~]$ sudo passwd stack
[hamzy@oscloud5 ~]$ echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack

I transfer over the built ppc64le overcloud images:

I then transfer over the built x86_64 overcloud images:

I then go through the process of installing the overcloud:
[stack@oscloud5 ~]$ source stackrc (undercloud) [stack@oscloud5 ~]$ time openstack overcloud image upload ...
The overcloud-full qcow2 image needs to be recreated in glance so that it loses both the kernel_id and the ramdisk_id. This way a full disk image can be deployed.
