This article describes my migration from Lightroom to open source alternatives, such as Darktable, using xmp sidecar files. I will explain the required migration steps, my photography workflow as well as a bit about the technical background. Preamble I used Adobe Lightroom for the past ten years. Although I am in no way a professional […]

Beginner friendly guide to windows virtual machines with GPU passthrough on Ubuntu 18.04; or how to play competitive games in a virtual machine.
Preamble The intent of this document is to provide a complete, step-by-step guide on how to setup a virtual machine(VM) with graphics cards(GPU) passthrough – detailed enough that even Linux rookies are able to participate. The final system will run Xubuntu 18.04 as host operating system(OS), and Windows 10 as guest OS, considering gaming as […]
Synchronization between photo development tools, or the migration from Lightroom to open-source alternatives.
This article describes settings, steps and problems during the migration process from Lightroom to open-source alternatives.
CPU-pinning and further performance tweaks for virtual machines on AMD Ryzen CPUs
Considering gaming as the main use case for my passthrough setup I try to minimize the latency on the guest (don’t bother, straight to the config). One knob to turn in order to squeeze out more snappiness is CPU-pinning. This will allocate CPU-cores for mainly (or solely) Guest tasks, when the Guest is running. One […]
Fighting error 43 – Nvidia GPU in a virtual machine
The infamous error 43 is the answer of Nvidia windows driver, in case it recognizes the GPU is used inside a virtual machine with GPU passthrough. Luckily, with a few tweaks in the virtual machine configuration file the Nvidia driver can be tricked. System setup This method worked for me with these system evironment: Host: […]
Virtual machine audio setup – or how to get pulse audio working
In this post, I compare several options of how to get the sound output from an KVM virtual machine guest, back into the host. I will compare spice server, pulse audio and a hardware solution. The complete guide on how to setup a virtual machine with GPU passthrough in Ubuntu 16.04 can be found here. […]

Configuring Hugepages to use in a virtual machine
Hugepages are an optional step during the VM configuration; it increases the RAM performance of the virtual machine. The downside is that the RAM allocated to the hugepages can not be used in the horst system, even if the guest isn’t running. The minimum size should be not smaller then 4GB. Check if hugepages are […]
Different ethernet setups for virtual machines
Still in draft: – using bridge device * -> easiest, fastest and most convenient way, but requires wired connection. – using network tap – using host mode libvirt’s default setup where the VM host more or less acts like a NAT router for all the virtual machines running on it. This works out of the […]
