Android X86 – No Mouse Cursor in Oracle VirtualBox I have recently installed AndroidX86 (android-x86_64-6.0-r1.iso) in VirtualBox 5.1.12 r112440 (Qt5.6.2) following these instructions. 

But I see no mouse cursor on the screen. Do I need to set some special preference?
The solution is change Pointing Device type to PS/2 Mouse:


Make sure the VM is not running (powered off)
Click on the VM name in the list (e.g., Android X86)
Click Settings
Click on the System category
Make sure you’re on the Motherboard tab
Change Pointing Device to PS/2 Mouse
