In this lecture, we move beyond traditional system administration and explore how Agentic AI can be used to fully control and manage a Proxmox VE environment.

Instead of manually logging into dashboards or executing commands, you will learn how modern AI agents can take over operational responsibilities and perform real system-level tasks with precision and speed.

Using advanced tools such as Claude Code and OpenAI Codex, we demonstrate how AI is no longer limited to writing code but can actively operate infrastructure.

By the end of this lecture, you will understand how to:

• Manage virtual machines and containers using AI agents

• Execute Linux administration tasks without manual intervention

• Automate infrastructure workflows and repetitive operations

• Troubleshoot and resolve system issues using AI-driven execution

• Shift from traditional administration to autonomous infrastructure management

This lecture introduces a new paradigm where AI acts as a system operator, not just an assistant. You will see how agentic platforms enable you to delegate tasks and control your infrastructure using natural language and intelligent automation.

Whether you are working with homelabs, enterprise environments, or cloud-integrated systems, this approach represents the future of IT operations.

In this lecture, you will learn how to fully prepare your Proxmox VE host to support GPU passthrough for virtual machines. We will enable IOMMU, configure GRUB, blacklist host GPU drivers, identify PCI device IDs, bind the GPU to the vfio-pci driver, and verify successful passthrough support following a reboot.

By the end of this lecture, your Proxmox host will be fully ready for attaching a physical GPU to a VM, enabling advanced use cases including gaming, 3D rendering, media servers, and AI workloads.

Understand the fundamentals of managing virtual machines and containers in Proxmox, setting the stage for efficient deployment and utilization.

Learn how to create and manage virtual machines in Proxmox, including configuration settings, resource allocation, and best practices for optimization.

By the end of this lecture, you'll be able to confidently integrate additional network adapters into your Proxmox setup, enhancing its flexibility and connectivity.

In this lecture, we walk you through the configuration of pfSense specifically for use with Proxmox Virtual Environment (VE). While integrating pfSense into your Proxmox setup is optional, it offers increased flexibility and control over your networking, routing, and firewall management.

In this lecture, we explore the installation of pfSense, an open-source next-generation firewall (NGFW) solution, and discuss why you might want to integrate it into your network infrastructure. While pfSense is not directly part of Proxmox, it serves as a powerful tool for managing your physical network or software-defined network (SDN).

Key takeaways include:

• Understanding the role of pfSense as a firewall, router, and gateway in modern networks.

• Why pfSense is a great choice for enhancing network security, performance, and flexibility.

• How pfSense can complement your existing Proxmox setup by providing advanced routing and gateway capabilities.

By the end of this lecture, you’ll see how pfSense fits into the broader picture of creating a robust and secure networking environment for your physical or virtual infrastructure.
