If the installed Guest Additions and VirtualBox version don’t match, that means Guest Additions didn’t install properly. In the first tab, click on Find and enter Guest Additions information report. If no window appears, we go to My computer and double-click on the virtual drive that VirtualBox has created to install the set of applications and drivers. VirtualBox comes with openSUSE and should work out-of-the-box. Launch VirtualBox, right-click the VM from the left pane, and select Show Log.
