# Ansible Arch Linux Libvirt Lab
|
||||||
|
|
||||||
|
This playbook is intended to help automate the deployment of Arch Linux guests to libvirt on localhost.
|
||||||
|
|
||||||
|
This exists mainly as an excercise while I teach myself ansible, and is mostly a reimplementation of this article: gitea@git.thurstylark.com:thurstylark/ansible-arch-libvirt-lab.git
|
||||||
|
|
||||||
|
As always, patches welcome!
