Dive in and transform your home lab into a powerhouse of innovation!
Unlocking Your Home Lab’s Potential: Top Proxmox Projects
Project-based learning offers immense rewards, especially in the realm of home lab automation. Dedicating a few hours on a weekend can dramatically advance your skills and infrastructure. If you’re looking for impactful projects to tackle in your Proxmox environment, here are five strategies to level up your setup.
Automate Linux & Windows VM Templates with Packer
Building efficient automation workflows is paramount for productivity in any `self-hosting` environment. Manually creating Windows or Linux virtual machine images for deployment is incredibly time-consuming and prone to inconsistencies.
HashiCorp Packer is an invaluable tool that streamlines this process, ensuring repeatable and consistent VM template generation. While traditionally popular in vSphere setups, Packer excels within Proxmox, allowing you to quickly provision base images for your personal cloud services.
A sample Packer template for Proxmox that builds an Ubuntu 24.04 Server looks something like this:
packer {
required_plugins {
qemu = {
version = “>= 1.0.0”
source = “github.com/hashicorp/qemu”
}
}
}
variable “iso_url” {
type = string
default = ”
}
source “qemu” “ubuntu” {
iso_url = var.iso_url
output_directory = “output-ubuntu-template”
vm_name = “ubuntu-template”
disk_size = 20480
format = “qcow2”
accelerator = “kvm”
ssh_username = “ubuntu”
ssh_timeout = “10m”
http_directory = “http”
communicator = “ssh”
Enable Cloud-Init ISO
cloud_init_iso = true
VM hardware
qemuargs = [
[“-machine”, “type=pc,accel=kvm”]
]
}
build {
sources = [“source.qemu.ubuntu”]
provisioner “shell” {
inline = [
“sudo apt update -y”,
“sudo apt install -y qemu-guest-agent”
]
}
}
You can also build up a Windows Server 2025 template easily as well. Check out my full blog post just on this topic here:

Stand Up a Proxmox Backup Server (PBS)
If you haven’t yet deployed a Proxmox Backup Server (PBS) in your environment, now is the critical time. Perhaps no other project offers a higher return on investment for your time than setting up robust backups. `Data sovereignty` and recovery are absolutely essential, even in a home lab. A single mistake or hardware failure could wipe out weeks or months of work.
Proxmox Backup Server is a free, purpose-built backup solution from Proxmox designed to securely store and restore your virtual machines and LXC containers. It ensures that in the event of a disaster, you can recover not just your data, but also your crucial VM and LXC configurations. Its block-level deduplication is particularly efficient, saving significant storage space compared to traditional backup methods.

Deploy Self-Hosted AI with Ollama and OpenWebUI with GPU Passthrough
Artificial Intelligence is transforming computing, offering unprecedented power for efficiency and innovation. However, relying solely on cloud-based AI solutions often comes with privacy implications and recurring costs. For those passionate about `self-hosting`, deploying your own private AI server is now more accessible than ever.
Leverage free and open-source tools like Ollama and OpenWebUI to create your own secure, private AI environment within Proxmox. This weekend project allows you to harness AI capabilities without compromising data sovereignty. With GPU passthrough, you can unlock significant performance for local Large Language Models (LLMs), turning your home lab into a powerful AI compute cluster. A recent example of this power is the ability to run impressive models like Llama 3 locally, which was once thought impossible on consumer hardware.

Spin Up a TrueNAS VM with PCIe Disk Passthrough
While TrueNAS excels on bare metal, running it as a virtual machine within Proxmox offers a compelling hybrid approach. This setup allows you to benefit from Proxmox’s robust High Availability (HA) and snapshot capabilities, all while leveraging ZFS’s unparalleled data integrity features inside the TrueNAS VM.
By passing through disks directly to your TrueNAS VM via PCIe, you can achieve near-bare-metal performance, combining ZFS’s reliability with Proxmox’s flexible orchestration, snapshots, and live-migration features. This creates a highly resilient and performant storage solution for your self-hosting needs.

Set up Proxmox Monitoring with Prometheus, InfluxDB, and Grafana
Without comprehensive monitoring, operating your Proxmox server or cluster is like flying blind. Understanding performance bottlenecks, resource utilization, and potential issues is crucial for maintaining a stable and efficient `personal cloud` environment.
By implementing a free and open-source monitoring stack—comprising Prometheus for data collection, InfluxDB for time-series data storage, and Grafana for visualization—you gain deep insights into your Proxmox infrastructure. This powerful combination allows you to proactively identify and troubleshoot problems, ensuring optimal performance for all your self-hosting services.
I wrote up an example of how to use this step-by-step here in this blog post for your reference and review: InfluxDB Grafana Docker-Compose Configuration: Proxmox Monitoring Example.

FAQ
Question 1: Why is self-hosting important for tech-savvy users?
Answer 1: Self-hosting offers unparalleled control over your data, enhanced privacy, and the freedom to customize services precisely to your needs, unlike public cloud solutions. It’s a fantastic way to learn, experiment, and ensure `data sovereignty` for your digital life, turning your home lab into a true `personal cloud`.
Question 2: What makes Proxmox Backup Server (PBS) essential for data resilience in a personal cloud?
Answer 2: PBS is crucial because it provides robust, deduplicated, and encrypted backups specifically designed for Proxmox VMs and containers. Its efficient block-level deduplication saves significant storage, and features like integrity checks and incremental backups ensure your data can be reliably recovered after any hardware failure or accidental deletion, safeguarding your valuable `self-hosting` projects.
Question 3: How feasible is deploying private AI models like Ollama with GPU passthrough in a home lab?
