Ansible Throws Error On Bootstrap (AIO-SX)

[Ceyhun Şen]

Brief Description
-----------------
At step 4 (Run the Ansible bootstrap playbook) of AIO-SX bootstrapping, Ansible throws error. Error is:

Severity
--------
Critical

Steps to Reproduce
------------------
1. Follow the steps on https://docs.starlingx.io/r/stx.8.0/deploy_install_guides/release/bare_metal/aio_simplex_install_kubernetes.html.
2. Use this Ansible overwrite file:

system_mode: simplex

dns_servers:
  - 8.8.8.8
  - 8.8.4.4

external_oam_subnet: 192.168.1.0/24
external_oam_gateway_address: 192.168.1.1
external_oam_floating_address: 192.168.1.200

admin_username: admin
admin_password: ***
ansible_become_pass: ***

Expected Behavior
------------------
Run Ansible playbook, provided by StarlingX and finish succesfuly.

Actual Behavior
----------------
Ansible won't finish and can't continue to the next steps.

Reproducibility
---------------
Reproducible
This error is seen after the fresh install. After running Ansible playbook once, error will change slightly:

Turns out, no memory on second RAM bank causes this problem:

https://opendev.org/starlingx/config/src/branch/r/stx.8.0/sysinv/sysinv/sysinv/sysinv/agent/node.py#L344 looks to sysfs for hugepages. But when there is no second RAM on the second RAM bank on my motherboard, Linux won't create hugepage directories. Then this code will just leave second NUMA node's hugepage entries `None`. Lastly, puppet tries to do some arithmetic on None values and throws exceptions.

As I said, connecting second RAM to second RAM bank on my motherboard fixed the problem. This bug can be closed.
