On a CentOS7 system

[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

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

        },
        {

            "mac":[

            "pm_addr":"9.114.118.155"
        }
    ]
}
__EOF__

I transfer over the built overcloud images:

[hamzy@pkvmci853 ~]$ (OCB=$(dig @192.168.122.1 -4 +short Overcloud.virbr0); UC=9.114.118.98; ssh-keygen -f ~/.ssh/known_hosts -R ${UC}; ssh-keyscan ${UC} >> ~/.ssh/known_hosts; scp -3 hamzy@${OCB}:~/*{initrd,initramfs,kernel,vmlinuz,qcow2}* stack@${UC}:~/)

I then modify undercloud.conf as follows:

And install the undercloud:

[stack@oscloud5 ~]$ time openstack undercloud install 2>&1 | tee output.undercloud.install
...
Undercloud install complete.
...

There is a bug for needing the userid for machines using ipmi that needs to be patched around.

Before I deploy the overcloud I have to fix another bug.
