Creating a stretched Layer 2 network for VMs on bhyve and FreeBSD

(2025-09-04):
In today's globalized IT landscape the term "cloud" dominates conversations about infrastructure, applications, and deployment strategies. Public cloud providers promise scalability, flexibility, and resilience but yet many organizations still operate their own infrastructure for reasons of control, cost, and compliance... In these environments, FreeBSD continues to play an important role as a robust, secure, and versatile operating system. One of the powerful tools in the FreeBSD ecosystem is CBSD ( github ). CBSD acts as a management layer that simplifies the handling of FreeBSD jails, bhyve virtual machines, and other system resources. Instead of manually working through complex configuration steps, administrators can rely on CBSD’s unified command-line and TUI interfaces to create, configure, and maintain VMs and containers with ease. In particular, CBSD makes bhyve—the native FreeBSD hypervisor—far more accessible, allowing administrators to spin up virtual machines quickly and efficiently. While virtualization is an essential building block, networking remains equally .... [read more]

How My BoxyBSD Project Boosted the Proxmox Ecosystem

(2025-06-06):
When I first started BoxyBSD, I had a fairly straightforward goal in mind: Build a completely free VPS hosting platform with full IPv6 support aimed at beginners and small open-source projects. Something simple, lightweight, and accessible. But as the project evolved, I realized it was becoming much more than just a small personal project and BoxyBSD started giving back - not only to open-source in general but also to the Proxmox community in ways I hadn't anticipated. What surprised me the most was how deep I had to dive into architectural decisions that I initially thought wouldn't matter that much - surprisingly it also changed my whole initial idea running everything on FreeBSD with bhyve - and let me say - it should become completely different! Managing resources efficiently across multiple VMs, fully automated deployment, monitoring system including all guests, clustering across different locations and live migrations of guests - ....

Run FreeBSD, OpenBSD and NetBSD VMs in Incus

(2025-05-05):
Not too long ago, I published a blog post all about Incus. In it, I gave an overview of the project, explained how it works, and showed how to create a cluster with it. After sharing it on social media, I started getting a lot of questions, and one in particular kept coming up: is it easy to run BSD-based virtual machines with Incus? Some people were even surprised to learn that Incus now supports virtual machines thanks to its QEMU backend. So I thought, why not follow up and walk through just how simple it is to get FreeBSD, NetBSD, and OpenBSD running using cloud images? It’s actually a pretty smooth experience. The Incus tooling makes it fairly straightforward to work with VMs, and the BSD community provides ready-to-use cloud images that fit right into this workflow. This means there’s no need to manually install or configure these systems .... [read more]

HowTo: Kleene as a Container Management Platform for FreeBSD

(2025-02-14):
Kleene is a container management (jail manager) platform designed specifically for FreeBSD, bringing familiar concepts from Docker while fully embracing FreeBSDs native tools and philosophy. Instead of reinventing the wheel, Kleene follows the KISS (Keep It Simple, Stupid) principle, leveraging FreeBSD’s built-in features to simplify application deployment, maintenance, and upgrades without unnecessary complexity or abstraction. By using FreeBSD’s core technologies like jails, ZFS, and PF (Packet Filter), Kleene provides a streamlined way to build, run, and manage containerized applications while maintaining transparency and control. Key functionalities include: Jailed Applications: Running lightweight, isolated environments using ZFS for storage efficiency. Native Networking: Automatically setting up necessary network devices and configurations. Firewall Integration: Managing connectivity securely with FreeBSD’s PF firewall. Unlike some container solutions that introduce heavy layers of abstraction, Kleene stays true to FreeBSD’s “Power to Serve” motto, ensuring users retain full visibility and control over their system. If you’re familiar with .... [read more]

Virtualization in 2024: Market Trends, Open-Source Opportunities, Broadcom’s VMware Shake-Up, and Top Solutions to Watch

(2024-12-10):
The year 2024 marked a turning point for the virtualization industry. Following Broadcom’s acquisition of VMware, significant changes to VMware’s licensing model and pricing structure set off a wave of responses across the market. These changes had a profound impact on the virtualization landscape, altering long-held assumptions and forcing enterprises to re-evaluate their strategies. VMware had long been a leader in the virtualization space, with its solutions forming the backbone of countless enterprise data centers. Its platforms, including vSphere, vSAN, and NSX, were considered industry standards, praised for their robustness and feature set. However, post-acquisition, VMware’s licensing and pricing underwent substantial revisions. For many organizations, these changes represented a significant cost increase, leading to concerns about the sustainability of continuing with VMware’s solutions. The updates, while intended to align with Broadcom’s broader enterprise strategy, prompted businesses to reexamine their dependence on proprietary virtualization platforms. This shift created ripple effects, opening .... [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]

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]

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]
