bhyve on FreeBSD and VM Live Migration – Quo vadis?
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 .... [read more] |
Run Linux Containers on FreeBSD 14 with Podman
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 .... [read more] |
FreeBSD: How Can We Make It More Attractive to New Users?
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 .... [read more] |
Automate FreeBSD VMs on Proxmox with Terraform and ProxLB
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 .... [read more] |
Use a USB Network Adapter for XCP-ng Management Easily
When you connect an external USB network (Ethernet) dongle to a node running XCP-ng, you might encounter an issue where the device appears as a "side-NUMBER-eth0" interface. This interface, however, is not connected and cannot be used for any management interfaces within XCP-ng. You may still be able to manually configure it and to assign IP addresses but it will ....

XCP-ng: Lightweight, Powerful Xen Virtualization
After Broadcom increased the license fees, other virtualization solutions than VMware ESXi become very popular. I already talked about other solutions like CBSD, running on FreeBSD using bhyve for virtual machines (VM) workloads or Harvester, as an HCI solution that also allows you to run VM in a different approach. However, we mostly hear Proxmox in one of the first .... [read more] |
ProxLB: Maximize Proxmox Cluster Performance Easily
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, ....

Harvester - A More Modern Alternative to Proxmox As a HCI
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 ....

ClonOS - An Alternative to Proxmox Based on FreeBSD
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 .... [read more] |
