I had some issues getting OpenSUSE to work in a virtual environment. The mouse and keyboard were not working. To make this work, i restarted the virtual machine and entered a ‘3’ at the Grub bootloader prompt to start OpenSUSE in runlevel 3. In this level the keyboard works ok.

Next I edited the file /etc/X11/xorg.conf and placed the following section at the top of the file:

Section "ServerFlags"
  option "AutoAddDevices" "off"
EndSection

… and restarted the computer. Both the keyboard and the mouse are working now.
