Switch from from ICH9 to AC97 (sound) via Virt-Manager Guest features resolves the issue in meantime. Sound from youtube's video running inside VM starts to go via external speakers. Tested for F41 KDE Spin Guest at ArchLinux Plasma 6.2.3 KVM Virtualiztion Host as well. Also notice that Fedora 41 KVM Virtualization Server works with any deployed guest and Arch Linux Plasma in particular via Spice Console with default option ICH9 without any problems.
First DE supposed to be installed is KDE Plasma 6.2.3, installation follows instructions proposed in thread https://github.com/archlinux/archinstall/issues/2764 due to known issue with pipewire-pulse.service in arch ISO version as of 11/01/2024
# pacman -Sy git
# git clone https://github.com/archlinux/archinstall
# cd archinstall
# python -m archinstall
Managing this way you come through Piperwire section of archinstall without any trouble.
After reboot we may install Stephan's Raabe Hyprland ML4W 2.9.6.5 Dotfiles straight away via commands
$ sudo pacman -S --needed base-devel git $ git clone https://aur.archlinux.org/yay.git $ cd yay $ makepkg -si $ yay -S ml4w-hyprland $ ml4w-hyprland-setup Original video may be seen here https://www.youtube.com/watch?v=JT_YHknWfKs
Switching to Plasma DE may be performed via really nice prompt screen which can inherit wallpaper has been setup for Hyprland session
Login prompt screen was done in VENV
I was forced to enable 3D accelearation && OpenGL and bring up just once KVM instance of F41 KDE Spin to obtain option Desktops Effects => Windows Management => Cube visible for activation. Six virtual desktops had been already activated. Afterwards Super+"C" started to work. Then I shutdown F41 KDE instance and disabled 3D accelearation && OpenGL. Following runtime sessions of F41 KDE KVM Guest would have Cube Desktop feature enabled and Super+"C" functional even in normal UEFI mode with disabled options 3D accelearation && OpenGL of Virtual-manager.
So in normal UEFI mode session of Virt-manager F41 still keeps required for Cube Desktop options enabled and Cube Desktop feature functional
Same way behaves Arch Linux Plasma 6.2.2 KVM Guest regarding Cube Desktop feature activation
UPDATE as of 10/26/24. Cockpit Web Console supports Fedora's 41 Server's KDE RC 1.4 Cube Desktop Feature described above
Straight forward install Pycharm-community-2024.2.3 via extracting tar ball either snap will fail showing up following error
boris@localhost:~/Downloads/pycharm-community-2024.2.3/bin> ./pycharm.sh
**Start Failed**
Internal error
java.lang.InternalError: Unable to load native GTK libraries
To avoid this failure libgthread-2_0-0 is supposed to be preinstalled :

Pyenv is a tool for managing multiple Python versions. Once pyenv is installed you can easily switch between one project that uses Python 3.13.0 and a system-wide default Python 3.12.7.
$ git clone https://github.com/pyenv/pyenv.git ~/.pyenv
The following two installs are required to perform successful build Python 3.13.0 for particular user via pyenv. This build won't affect system-wide Python 3.12.7
$ sudo pacman -S base-devel
$ sudo pacman -S tk
Now we update ~/.bashrc as follows :
$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(pyenv init --path)"' >> ~/.bashrc
$ source ~/.bashrc
$ pyenv install 3.13.0
Downloading Python-3.13.0.tar.xz...
-> https://www.python.org/ftp/python/3.13.0/Python-3.13.0.tar.xz
Installing Python-3.13.0...
Installed Python-3.13.0 to /home/boris/.pyenv/versions/3.13.0
$ pyenv global 3.13.0
Notice that Pycharm projects running 3D plots requires PyQt6 to be
installed in particular virtual environment of this project
Perform standard install KDE Plasma 6.1.5 on Arch Linux as KVM instance. Then add following lines right above core-testing entry :-
[kde-unstable]
Include = /etc/pacman.d/mirrorlist
into /etc/pacman.conf
When /etc/pacman.conf would be updated issue
$ sudo pacman -Syu ; $ sudo reboot
Next step would be install Hyprland (ML4W 2.9.6.1) via Paru as suggested below
$ git clone https://aur.archlinux.org/paru-git.git
$ cd paru-git
$ makepkg -si
$ paru -S ml4w-hyprland
$ sudo reboot
$ ml4w-hyprland-setup
$ sudo reboot
Log into Hyprland via updated SDDM promt
Then you may run neofetch for instance inside Hyprland (ML4W 2.9.6.1) DE
Looks like presence on Fedora 41 Server preinstalled KDE Plasma 6.2 Beta allows to setup Cosmic DE as second DE following https://copr.fedorainfracloud.org/coprs/ryanabx/cosmic-epoch/ . The most recent Fedora 41 KDE Spin behaves the same way as F41 Server.
The Fedora Project does not exercise any power over the contents of this repository beyond the rules outlined in the Copr FAQ at
<https://docs.pagure.org/copr.copr/user_documentation.html#what-i-can-build-in-copr>,
and packages are not held to any quality or security level.
$ sudo dnf copr enable ryanabx/cosmic-epoch
$ sudo dnf install cosmic-desktop
Commands below
$ sudo dnf5 install @kde-desktop-environment
$ sudo systemctl enable sddm # server's setup
$ sudo systemctl set-default graphical.target # server's setup
work at least in meantime for both F41 Server (no GUI installed by default ) and F41 WKS with Gnome 47 installed by default. Syntax above is mentioned due to command $ dnf5 group list doesn't help at the moment .

First tune Virt-manager as follows
Log into KDE Plasma6 DE and issue
$ sudo pacman -S cosmic
$ sudo reboot
There was typo in the header, the correct version is ML4W 2.9.6.1-1 Dotfiles
========================================================
Setup Arch Linux (minimal) using archinstall and the most recent ISO as of 09/01/24 along with base-devel git openssh sddm vim nano . We intend to perform both DEs installation using Paru as AUR Helper . Start with paru build
$ git clone https://aur.archlinux.org/paru.git
$ cd paru
$ makepkg -si
Now we need access to AUR via Paru AUR Helper :
$ paru -S cosmic
$ sudo reboot
$ sudo pacman -S packagekit
$ sudo pacman -S power-profiles-daemon
$ sudo systemctl enable sddm
$ sudo reboot
Verify Cosmic DE functionality
Continue with Hyprland (ML4W 2.9.6.1-1) installation as second DE been inside Arch Cosmic Instance
$ paru -S ml4w-hyprland
$ ml4w-hyprland-setup
When done reboot and log into Hyprland (ML4W 2.9.6.1)
Now verify some features of Hyprland DE functionality
The last snapshot verifies installation on Mission-Center on Hyperland with ML4W 2.9.6.1-1 Dotfiles (Stephan Raabe)
