Again, qemu changed virtual hardware

[Simon Becherer]

Hi, i like to ask again here:

how did i fix the virtual hardware that quemu will after updates
still send the guests the same hardware as before??

i updated today to 6.0.0-26.1 (opensusetumbleweed)

windows xp: lost the network controller, but has a identical new (e1000) 
network controller
           found, so i have to set up it new.

windows 10: a propetary software lost the licence because of the update of the 
linux qemu host.
            i have to order new key.


how could i prevent qemu from doing that AND hold my system up to date????
-> not updating qemu is not a solution.

start line from win10 (libvirt)
