Proxmox is awesome. :) Back several years ago I worked on a project to build a system for making demos of network solutions. We ran Proxmox inside of an ESX virtual machine and then used it to virtualise various pieces of the demo architecture. The ESX image could simply be coped to an external drive for the consultant to use. Ultimately the company went for a central-lab demo environment instead but it was pretty cool anyway. The demo itself was stored as a bunch of Ansible playbooks and assorted scrips so it was Git-friendly, to be applied to a generic ESX template. We built cool things like a canvas-based Visio-like UI that could be used to define VMs / containers / networks and provision at the touch of a button. Similarly the solution itself would be visualised using a diagram that supported dynamic components like links showing traffic, counters, graphs etc that would show traffic running between the VMs inside the demo. We also had a central server that would store pre-created demo templates using Ceph that could checked-out for use via a web UI. Fun times :)
