Building Modern Proxmox Infrastructures in 2025: Automated, Scalable, and Open for Everyone

(2025-08-11):
The Proxmox ecosystem has grown massively in recent months – and one of the key reasons behind this growth is the strong and active community that continues to push the project forward after the VMware aquisition by Broadcom. You can really feel the momentum. There is a lot happening around Proxmox, and the pace is only picking up. I see this every day in my own work. Proxmox has become one of the most important parts of my tech stack. It’s reliable, flexible, and can be used in so many different ways. Some use it in the classic ClickOps style through the UI. Others build semi-automated setups by using the tools Proxmox already provides. And then there are the fully automated deployments, which is where things really get interesting. That’s especially true if you’re moving away from other virtualization solutions. When you have multiple clusters, running in different locations and .... [read more]

BoxyBSD Empowers the Open-Source Community by Provisioning 500+ Free BSD-Focused VPS Instances

(2024-12-07):
This weekend marks an incredible milestone for BoxyBSD : we’ve provisioned our 500th free VPS instance! What started as a passion project aimed at supporting the open-source community has grown into something truly special, and I couldn’t be more proud to see the impact it’s having on learners, enthusiasts, and open-source contributors worldwide. Building a Bridge to BSD and Beyond BoxyBSD was born out of a simple yet powerful idea: to lower the barriers to entry for anyone eager to learn, experiment, or contribute to BSD-based operating systems. By providing free virtual private servers (VPS), I’ve been able to offer a platform where beginners can explore the intricacies of system administration, networking, and security practices without the financial burden of hosting costs. This mission also extends to supporting open-source projects. Many community-driven initiatives lack the infrastructure needed to thrive. BoxyBSD fills that gap by providing free hosting on a range .... [read more]

HowTo: Managing VM on FreeBSD with bhyve and vm-bhyve

(2024-10-26):
The bhyve hypervisor on FreeBSD is an impressive tool that brings lightweight, efficient virtualization capabilities directly into the FreeBSD ecosystem. It’s a powerful type 2 hypervisor that allows FreeBSD users to run virtual machines with minimal overhead, making it an excellent choice for those who value performance and stability. I find bhyve especially compelling for running various Unix-like operating systems like FreeBSD itself, Linux, and even Windows, thanks to UEFI support. In the past, I already wrote many blog posts about virtualization and hypervisor solutions where I also often mentioned bhyve but also the lacks around bhyve. However, bhyve is still an amazing way to virtualize your workloads by running VMs of any operating system. Recently I got ask how I usually manage bhyve and if I could provide a small howto. To manage bhyve VMs more easily, I rely on vm-bhyve, which streamlines the creation, configuration, and operation of .... [read more]

bhyve on FreeBSD and VM Live Migration – Quo vadis?

(2024-10-21):
When I think about bhyve Live Migration, it’s something I encounter almost daily in my consulting calls. VMware’s struggles with Broadcom’s licensing issues have been a frequent topic, even as we approach the end of 2024. It’s surprising that many customers still feel uncertain about how to navigate this mess. While VMware has been a mainstay in enterprise environments for years, these ongoing issues make customers nervous. And they should be – it’s hard to rely on something when even the licensing situation feels volatile. Now, as much as I’m a die-hard FreeBSD fan, I have to admit that FreeBSD still falls short when it comes to virtualization – at least from an enterprise perspective. In these environments, it’s not just about running a VM; it’s about having the flexibility and capabilities to manage workloads without interruption. Years ago, open-source solutions like KVM (e.g., Proxmox) and Xen (e.g., XCP-ng) introduced .... [read more]

Run Linux Containers on FreeBSD 14 with Podman

(2024-10-06):
In one of my recent blog posts, I shared my journey as a long-time FreeBSD user. I talked about how I’ve been incredibly happy with the system, appreciating its rock-solid stability, flexibility, and performance. But, like every OS, FreeBSD had its gaps, especially when it came to some modern developments – one of which has been a pain point for many of us working with containerized environments: native support for Docker and Podman Linux images. Until recently, this missing functionality made working with containerized applications a bit of a challenge. Let me explain why that’s changed and how FreeBSD 14 has finally caught up to the container party. The Old Way: bhyve Linux VMs For a long time, one of the workarounds for running Linux containers on FreeBSD was to spin up a Linux VM using bhyve, FreeBSD’s native hypervisor. While bhyve is fantastic in its own right (fast, lightweight, .... [read more]

FreeBSD: How Can We Make It More Attractive to New Users?

(2024-10-02):
For nearly 15 years, FreeBSD has been at the core of my personal infrastructure, and my passion for it has only grown over time. As a die-hard fan, I’ve stuck with BSD-based systems because they continue to deliver exactly what I need—storage, networking, and security—without missing a beat. The features I initially fell in love with, like ZFS, jails, and pf, are still rock-solid and irreplaceable. There’s no need to overhaul them, and in many ways, that reliability is what keeps me hooked. My scripts from 20 years ago still work, and that’s a rare kind of stability that few platforms can boast. It’s not just me, either—big names like Netflix, Microsoft, and NetApp, alongside companies like Tailscale and AMD, continue to support FreeBSD, further reinforcing my belief in its strength and longevity (you can find the donators and sponsors right here). Yet, while this familiarity is comforting, it’s becoming .... [read more]

Howto: Automated FreeBSD VM Deployment with ProxLB and Terraform

(2024-09-01):
In today’s fast-paced IT environments, automation is essential for maintaining efficiency and staying competitive. Whether you're managing a small-scale infrastructure or an enterprise-level system, the ability to deploy virtual machines (VMs) quickly, consistently, and with minimal manual intervention can be transformative. This is where tools like ProxLB and Terraform come into play, offering a powerful solution for automating the deployment and management of VMs. Why Terraform and not Ansible? I'm aware that Ansible is a great tool - also for such things - but Ansible might be slow in some cases with too many tasks and not writing own custom modules that improve the overall handling. Terraform is often the better choice when it comes just to build up a base infrastructure from scratch where Ansible can take over after this baseline has been set. So, let's have a look at the other tools used here. ProxLB is a robust .... [read more]

ProxLB - (Re)Balance VM Workloads Across Nodes in Proxmox Clusters.

(2024-07-06):
ProxLB (PLB) is an open-source Proxmox loadbalancer, but different! ProxLB is an application created to optimize the distribution of virtual machines (VMs) across Proxmox cluster nodes for significantly enhancing efficiency and performance. Utilizing the Proxmox API, ProxLB gathers and analyzes a comprehensive set of resource metrics from both the cluster nodes and the running VMs, including CPU usage, memory consumption, and local disk utilization. A key feature of ProxLB is its intelligent rebalancing capability, which redistributes VMs based on their memory, disk, or CPU usage. In those cases, the real memory consumption from the VM is taken instead of the potential maximum usage. This ensures no single node is overburdened while others remain underutilized, significantly enhancing cluster performance and reliability. By evenly distributing resources, ProxLB helps prevent performance bottlenecks and improves the overall stability of the cluster. Efficient rebalancing leads to better utilization of available resources, potentially reducing the need .... [read more]

Harvester - A More Modern Alternative to Proxmox As a HCI

(2024-06-25):
After Broadcom increased the license fees, other virtualization alternatives become very popular. While I previously already evaluated various virtualization platforms, including Proxmox, as well as other solutions that are based on FreeBSD, such as bhyve-webadmin (BVCP), and ClonOS there are of course also several other ones and it is worth noting another noteworthy option in the landscape of hyperconverged infrastructure (HCI). Harvester is an innovative, open-source HCI platform that is built atop of Kubernetes, offering a cloud-native approach to infrastructure management. It is tailored for operators who are in search of an open-source HCI solution that can seamlessly integrate with their existing systems. Harvester is engineered to be deployed directly on bare metal servers, where it provides a combination of virtualization and distributed storage functionalities. This solution is not limited to managing traditional virtual machines, it also embraces the containerization trend by facilitating containerized workloads through its integration with Rancher. ....

ClonOS - An Alternative to Proxmox Based on FreeBSD

(2024-06-21):
In the realm of virtualization, there are already several robust and well-established platforms like Proxmox and OpenStack. These solutions have paved the way for efficient and comprehensive management of virtual environments, primarily on Linux-based systems. However, for those who appreciate the power and elegance of FreeBSD, there has been a notable absence of a comparable tool that leverages this operating system's unique strengths. With ClonOS (mainly written by Oleg G. and Oleg M.) an innovative open-source solution that fills the gap by offering a turnkey solution based on FreeBSD and the CBSD framework, we are finally receiving a solution that also offers the missing enterprise features like multiple node support to create clusters and live migrations for virtual machines. ClonOS is designed to provide seamless control, deployment, and management of FreeBSD jails containers, but also of virtual machines (VMs) with bhyve to create virtual environments. Built on the powerful CBSD .... [read more]
