VirGL for Linux KVM guests on Ubuntu Desktop

NOTE: Please don't ask for help here, it was a miracle that I got it to work at all. Seek answers in the usual places (yes, even Stackoverflow knows more than I do).

The question: How can I get 3d accelerated graphics for Linux guests in KVM without using PCI passthrough?

The short answer is: Use VirGL. The long answer is more complicated, because the VirGL project has had slow but steady progress towards actually working reliably, but the degree to which any given Linux distribution (or related driver project) is in sync has varied greatly over time. Even if it works right now, today, on your machine, it might not tomorrow. Note that even when it works, graphics performance is mediocre to downright painful.

Tested on Ubuntu Desktop 22.04.04 LTS with qemu-kvm, in an "Ubuntu on Xorg" session (not Wayland). Linux quests must have spice-vdagent installed (Ubuntu installs this by default). The hardware is a AMD 5600G d

How to install Unity3D on Ubuntu based Linux distros (Kubuntu, Xubuntu, POP_OS, Mint, Neon, Zorin, etc.).

This guide details how to install UnityHub, Unity, VS Code and how to get full C# support with IntelliSense and debugging.

Tested on Kubuntu 22.04.

Installing Unity Hub

Unity Hub won't run on Ubuntu newer than 20.04 because it depends on an outdated libssl. We need to manually install the package from 20.04:

Install Arch on OVH VPS

This guide will show you how to install Arch Linux on an OVH VPS.
As you may have noticed, OVH does not have an Arch image, which is a problem. Follow these instructions to install Arch using recovery mode.

NONE OF THESE CLIENTS ARE VERIFIED BY ME FOR SECURITY OR ANYTHING ELSE! USE AT YOUR OWN RISK!

These are the current alternatives (with links when possible):

• NewPipe (which you should have either way for youtube-dl/yt-dlp integration)
• NewPipe fork by polymorphicshade, which includes SponsorBlock support.
• LibreTube (still in early beta)
• A web browser with uBlock Origin (or another ad-blocker; Enhancer for YouTube has one build-in, but uBlock is universal and more powerfull, in addition to allowing to also remove non-advertisement parts of the website, like the top shelf with recommended tags / search querries), Enhancer for YouTube, SponsorBlock and [Return YouTube Dislike](https://

Real developers are not used to clicking, it's allways easier to write a script to do it for you.

Also, here are some Transport settings you might want.

Although not explicitly stated, DNS resolution appears to be taken into consideration as part of the overall http.Client.Timeout setting. If you need to set your own DNS timeout, then it seems https://github.com/miekg/dns is a popular solution.

Additionally, it's important to realise how golang resolves hostnames to IPs (i.e. DNS resolution):

Cloudflare doesn't allow disabling IPv6 via their Dashboard any more. This works:

curl -X PATCH "https://api.cloudflare.com/client/v4/zones/<zone-id>/settings/ipv6" \
  -H "X-Auth-Email: <email>" \
  -H "X-Auth-Key: <auth-key>" \

High Traffic Server Settings on RHEL / AlmaLinux / Rocky / EuroLinux / CentOS 8

I recently did some work to optimize the network configuration of an AlmaLinux 8 based web server that receives a lot of traffic.

Of course these settings also apply to RHEL / Rocky / EuroLinux / CentOS 8 (hereafter referred to as Linux 8.) I think these should also work on RHEL / AlmaLinux / Rocky / EuroLinux 9 as well but I have not yet tested them.

There is a lot of information on the web for this and it distills down to a minimum recommended configuration, and a recommended configuration.

The minimum recommended configuration should be sufficient for servers with less than 10Gb, and the recommended configuration should be sufficient for servers with 10Gb or more.
