Who is in charge of Leap 15.3 initial configuration?

Could anyone tell me who is in charge of handling the initial configuration of Leap 15.3. As reported in bsc#1183125, an installation of Leap 15.3 in a VirtualBox VM does not install virtualbox-guest-x11 or virtualbox-guest-tools, and only suggests virtualbox-kmp-default. This behavior differs from that of previous versions which detected that the installation was under VirtualBox and installed these 3 additional packages. Thanks, Larry
