"systemctl preset-all" is intended to return service states to a factory state 
based on presets.
But currently we can see breakages in some products due to services that are 
not following the guidelines as described in

https://en.opensuse.org/openSUSE:Systemd_packaging_guidelines#Enabling_systemd_unit_files

The package
libvirt

was identified to use
"systemctl enable" in its spec-file, and it should get replaced by the proper
use of
%sytemd_add_pre/post and preset.

Please check your package, thanks.
