At Cyberus Technology, we've built openstack-nix, a NixOS-based solution that makes deploying and testing OpenStack more reliable and reproducible. It lets you spin up a complete OpenStack setup with a single command, run tests inside NixOS VMs, and customize configurations effortlessly. No more dependency headaches or cumbersome hardware setups - just clean, modular OpenStack deployments.

enclosed is a robust solution designed to simplify management and secure compartmentalization of virtual machines. With enclosed, we aim to address the challenges faced by users of low-level tools, such as libvirt, offering a higher level of abstraction and a user-friendly approach to creating and managing strongly isolated VM compartments. Learn how enclosed works and how to get started in this article!

Modern applications often require graphics acceleration to run at their full potential, which is often a problem in virtual machines. Graphics virtualization helps solve this and provide near-native graphics performance in virtualized environments. Read about the support for SR-IOV graphics virtualization we, at Cyberus Technology, have built into our KVM backend for VirtualBox.

Check out our latest blog post, "VirtualBox KVM Technical Deep-Dive," where we unveil the inner workings of our newly released VirtualBox KVM variant on GitHub. Explore the replacement of the original VirtualBox kernel module with a KVM hypervisor backend for Linux.

Dive into the technical details and discover how we optimized performance, especially for Windows guests: https://cyberus-technology.de/articles/vbox-kvm-deep-dive?ut...

We also pushed our latest state to github where we enabled more paravirtualization enlightenments for Hyper-V. These enlightenments improve VM performance for Windows 10 and Windows 11 guests.

For the past few months we have been working hard to provide a fast, reliable and secure KVM backend for VirtualBox. VirtualBox is a multi-platform Virtual Machine Monitor (VMM) with a great feature set, support for a wide variety of guest operating systems, and a consistent user interface across different host operating systems.

Cyberus Technology’s KVM backend allows VirtualBox to run virtual machines utilizing the Linux KVM hypervisor instead of the custom kernel module used by standard VirtualBox. Today we are announcing the open-source release of our KVM backend for Virtualbox.

Physical Infrastructure in the real-world has a much longer lifetime than software systems. This presents a number of challenges to operators:

* Hardware components fail at some point while spare parts are no longer available and need to be replaced by modern alternatives. * Old software lacks support for modern components and a major software upgrade is required for continuing operation.

Learn how this gap can be mediated and what can be done to solve this issue long-term.
