Setup firewalld and KVM on openSUSE Leap 16 Beta manually

UPDATE as of 05/10/2025

Per https://www.theregister.com/2025/05/09/opensuse_ditches_deepin/ 

You beta, you beta, you bet

Aside from the retreat on the Eastern front, where is openSUSE going next? Well, there is a roadmap to give the general direction. We looked at the plans for Leap 16 at the start of last year, and now the beta is here.

It sounds startlingly different from the openSUSE of old. The announcement delivers several shocks. It says it is "expected to be Wayland-only," although "some Xorg remnants remain for now." That will dramatically cut the range of desktops for a start – and eliminate most of this vulture's favorites.

But there's more sad news. "The traditional YaST stack is retired." Instead, users will get the Red Hat-backed Cockpit for web-based server management, and the new Myrlyn graphical package manager as a replacement for YaST's software tool.

====================================================

Finally I had decided to skip deployment templates for KVM Host and Cockpit Web Console for openSUSE Leap 16 Beta KVM Guest.  Due to absence of YAST on  openSUSE Leap 16 Beta guest I just issued following sequence of CLI directives which brought me to success with linux bridge been setup via Cockpit Web Console.
