+## Disclaimer:

+# Use it at your own risk. Ensure you test thoroughly in your environment
+# before deploying to production.
+
+# Ansible Playbook for Deploying VMs on Hypervisor and Setting Up Bastion Host
+
+## Overview:
+# This playbook automates the process of deploying virtual machines (VMs) on a hypervisor
+# and setting up the bastion host environment. It includes:
+# - Downloading and preparing VM disk images.
+# - Configuring network settings via cloud-init.
+# - Customizing VM images with SSH keys and root password.
+# - Installing necessary system RPMs and activating the operating system.
+# - Configuring SSH for passwordless access.
+
+## Prerequisites:
+# - Ansible 2.10+ installed on the control node.
+# - Ansible control node configured with necessary permissions.
+# - SSH Access to hypervisors hosts.
+# - VM qcow2 disk images and RPM links accessible via HTTP.
+
+## Roles Requirements
+# The playbook uses role:
+# - redhatci.ocp.create_vms: Creates VMs on given hypervisor.
+
+## Usage:
+# - Ensure all required variables are defined in the inventory or host_vars/group_vars.
+# - Execute the playbook using Ansible's command-line tool:
+#   ansible-playbook playbooks/infra/deploy-vm-bastion-libvirt.yml -i ./inventories/infra/deploy-bm-hypervisor.yml
+#
+

+#   vm_ram: "16384"                     # Amount of RAM allocated to the VM (in megabytes)
+
+# Roles/Tasks Overview:
+# 1. **Deploy VM on Hypervisor**
+#    - Download and resize VM QCOW2 images.
+#    - Apply network configurations via cloud-init.
+#    - Deploy VM using the customized image.
+#
+# 2. **Initial System Setup (Bastion Host)**
+#    - Install and activate the operating system.
+#    - Configure users, sudo access, and SSH settings.
+#
+# 3. **Setup Bastion Host**
+#    - Configure SSH keys for secure communication.
+#    - Set hostname and other critical system settings.
+#
+# Notes:
+# - This playbook assumes the hypervisor host is pre-installed and ready.
+# - Customize variables such as `vm_name`, `ansible_user`, and network settings to fit your environment.
+# - Test in a non-production environment before deploying.
