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

Sandboxed Google Play compatibility layer (gmscompat)

Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

As 2024 is winding down:

How to extract dylib from shared cache

To understand iOS behaviors, sometimes it’s important to disassemble iOS framework binaries.

Since recent iOS firmware, known as .ipsw file, contains non-encrypted root image, it’s easy to access these binaries. However, each framework binaries, dylib files, are placed in a shared cache file.

Thus, before disassembling it, we need to extract the one from the cache.

Grab all your wireguard configs from Mullvad and dump them in a folder. For this test, this folder is ~/wireguard/.
Add the following function to generate a list of all servers you have configs for

lswg ()  { 
    ls ~/wireguard/ | cut -d '-' -f 2 | sed 's/\.conf//'
}

Ping each server 10 times to determine latency.

lswg | xargs -I {} ping -c 10 {}-wireguard.mullvad.net | tee mullvadwgstats
