Having virt-manager installed makes presence of Cockpit Web Console optional . It's nice to have Cockpit Console installed, however it is not required. Presence edk2-ovmf is a must. Situation is the same on Tumbleweed, Ubuntu 22.04, Debian 12.(X), Manjaro Linux 23.1.3
Cockpit Client provides a graphical interface to your servers, containers, and virtual machines. Connections are made over SSH, using the SSH configuration of the local user (including aliases, known hosts, key files, hardware tokens, etc).
The server needs to have Cockpit installed, but the Cockpit webserver doesn't need to be enabled, and no extra ports need to be opened. The primary process in a Cockpit Linux session is called cockpit-bridge. It translates operating system interfaces to a JSON stream protocol, which is used by Cockpit browser pages.

How could packstack be interesting in meantime, unless RH brought it back to life ? I am not aware of Packstack's status this days.
UPDATE as of 03/27/2024
The most radical means of solving all problems would be to switch to Fedora 40 Beta either openSUSE Tumbleweed

KDE Plasma 6.0.2 may be ported to Manjaro 23.1 by commands
$ sudo pacman-mirrors --api --set-branch testing
$ sudo pacman -Scc
$ sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syu
If you are getting error :
error: failed to prepare transaction (could not satisfy dependencies)
:: installing pacman (6.1.0-4) breaks dependency 'libalpm.so=13-64' required by libpamac
Switch back to sudo pacman -Syyu . This error turns from random to regular for me. At the time of writing you are supposed to get message - Total (0/673) regarding number of packages ready to be installed .
Per advise of oioi@https://forum.manjaro.org/t/i-tested-kde-6-oh-my-oh-my-you-will-be-sorry-here-come-some-discoveries/158436/24 I issued `sudo pacman -S qt6-imageformats` :-

It fixes the problem on Manjaro testing all the way around . VENV screenshot first
I also believe that explanation provided at https://unix.stackexchange.com/questions/762064/what-is-the-different-between-pacman-syu-syyu-and-syuu is correct
-yy, it is generally not recommended. Use it only if you're having problems with your mirror. Unless your mirror is acting up and you want to switch mirrors, there is no reason to re-download every package DB file in its entirety every time you want to do an upgrade. You might want to use it when switching mirrors so that all your package DB files are consistent.

Porting KDE Plasma 6.0.2 to Manjaro 23.1 was performed by commands
$ sudo pacman-mirrors --api --set-branch testing
$ sudo pacman -Scc
$ sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
I may confirm the issue mentioned in https://forum.manjaro.org/t/i-tested-kde-6-oh-my-oh-my-you-will-be-sorry-here-come-some-discoveries/158436
Quoting the post on forum.mangaro.org above:
<<So after update (pacman -Syyu) you have no webp thumbnails in Dolphin and Gwenview cannot display those photos (webp). What will a typical user do? >>
I've also tested with no problems opening *.webp files via Dolphin on the most recent fedora 40 KDE nightly build. See snapshot :-
Attempt to open *.webp file via Dolphin KDE Plasma 6.0.2 port to Manjaro 23.1
Same test on openSUSE Tumbleweed
Same test on CachyOS 2024.3 (Arch Linux clone) and failure again. Clean KVM Guest was deployed , no user's porting
Neon KDE as of 03/21 performs just fine
UPDATE as of 04/06/2024
KVM guest deployed via manjaro-kde-23.1.4-240406-linux66.iso and upgraded to Manjaro Testing
is still affected by CVE-2024-3094.

I also tested OK opening *.webp files via Dolphin on the most recent fedora 40 KDE nightly build
UPDATE as of 03/21/24
I was able to find workaround and keep manjaro's testing repos to install KDE Plasma 6.0.2 after switching to libvirt's default network for particular KVM guest. Placing VM on linux bridge ( Linux bridging vs NAT ) seems to be the core issue for myself either it is/was just a matter of luck.
Just several hours later I noticed that my local mirror was removed from testing list, then I issued and succeeded
$ sudo pacman-mirrors --api --set-branch testing
$ sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
per What is the different between pacman -Syu, -Syyu and -Syuu?
-yy, it is generally not recommended.
Use it only if you're having problems with your mirror. Unless your
mirror is acting up and you want to switch mirrors, there is no reason
to re-download every package DB file in its entirety every time you want
to do an upgrade. You might want to use it when switching mirrors so
that all your package DB files are consistent.
END UPDATE
As of now `sudo pacman -Syu` installs KDE Plasma 6.0.2 on Manjaro Testing branch
