A Thousand Fewer Paths to Root
Last week, a publication caught my attention: ‘A thousand fewer paths to root’ from OpenAI, which covers 948 local privilege escalation vulnerabilities (LPEs) in Linux. Usually, about 30 such LPEs are found in a year. An LPE allows a user of a Linux system to gain root privileges without having the root’s password. One of the […]
Meet LINBIT at the CloudStack Collaboration Conference 2026, and a LINSTOR in CloudStack Development Roundup
LINBIT® is a Diamond Sponsor of the CloudStack Collaboration Conference (CCC) 2026, happening 18-20 November in Edinburgh, Scotland. It has been a busy development year for the LINBIT team. As the VMware exodus continues to drive alternative virtualization platform adoption, the team works to help VMware refugees land comfortably on the storage side of operations. […]
Using Shared SAN Storage with LINSTOR in Kubernetes for KubeVirt Live Migration
Many organizations that move virtual machines (VMs) to Kubernetes with KubeVirt already own a storage area network (SAN), and want to keep using it. LINSTOR®, developed by LINBIT®, usually provides highly available storage in Kubernetes by replicating volumes between nodes with DRBD®. When a SAN already makes the same LUN visible to every node, replication […]
The Benefits of Buying Support for Open Source Software in an AI Age
In this AI age the value of buying support can seem diluted. This is an exciting time where an AI agent or AI chat engine can give you an answer to a problem in seconds, even a complicated problem involving sophisticated software, configurations, and environments. However, there is a difference between an answer and a […]
Comparing Open Source Virtualization Platforms
More and more, businesses and companies are seeking to repatriate services and infrastructure from the cloud to on-premise or hybrid solutions. This might be for a variety of reasons. Whether repatriating is for cost savings, performance, security, control, or other reasons, it is happening. Increasingly, companies are turning to open source solutions when repatriating services […]
Changed Block Tracking (CBT) & VMware
Recently, I have noticed several relevant open-source workload orchestrators have introduced interfaces for working with Changed Block Tracking (CBT) data, including OpenStack Cinder CBT contract, Kubernetes CSI-snapshot-metadata, OpenNebula OneBex, and the XCP-n XenServer CBT guide. Proxmox VE, Apache CloudStack, and oVirt do not currently have a storage-side API to query CBT. (Proxmox VE and oVirt […]
Methods for Migrating Virtual Machines From VMware ESXi to Linux-Based Hypervisors
Many system administrators have been migrating away from VMware ESXi due to extreme increases in total cost of ownership (TCO) since Broadcom acquired VMware. After deciding which platform is right for your environment, the next question is how to get your virtual machines (VMs) and their data onto the new platform. There are several general […]
Discover System76: A Partner in Open Source
In the past I’ve written about how LINBIT uses open source software throughout our infrastructure. Our commitment to open source extends further than our code and our business applications. We also support the hardware vendors that contribute back to the open source community. One such vendor is System76. We’ve used their hardware for servers, laptops, […]
Kubernetes Roundup – LINSTOR Operator 2.12.0 Release & Updates
I’ll begin this Kubernetes roundup by sharing details about the new LINSTOR Operator 2.12.0 release. The new standout feature is support for shared storage. The Operator can now register LVM storage pools backed by storage shared between nodes, such as a SAN. LINSTOR CSI builds on this: RWX block volumes no longer need a DRBD […]
Insight into the latest DRBD Release
Just a couple of days ago, I released drbd-9.2.20 and drbd-9.3.4, which was an unusual release. As I explained in the release notes, we fixed more issues than in any previous development cycle. This is because the team has used ClaudeCode since the start of the year. From our first experiments, it took around six […]
