Ansible playbook to set some extra specs on OS level. Tested on bubuntu Mitaka Legacy stack.
hosts file should contain compute section, example below:

freak-without-dns-and-without-group ansible_connection=ssh ansible_user=mpdehaan ansible_port=5555 ansible_host=192.0.2.50
[controller]
controller-[1:3]
localhost ansible_connection=local
[compute]
compute-[1:4]
compute-access-with-root-hosts-[7:9] ansible_user=root

More info on hosts inventory found here.

execution: ansible-playbook -i hosts main.yaml

sysstat is already installed on ubuntu so just enabling it.

Thank you
