# ==========================================================
# Description:
# This script is part of the central ProxMenux VM creation module. It allows users
# to create virtual machines (VMs) in Proxmox VE using either default or advanced
# configurations, streamlining the deployment of Linux, Windows, and other systems.
#
# Key features:
# - Supports both virtual disk creation and physical disk passthrough.
# - Automates CPU, RAM, BIOS, network and storage configuration.
# - Provides a user-friendly menu to select OS type, ISO image and disk interface.
# - Automatically generates a detailed and styled HTML description for each VM.
#
# All operations are designed to simplify and accelerate VM creation in a 
# consistent and maintainable way, using ProxMenux standards.
