You can configure this in File > Preferences in your main VirtualBox control panel. One thing that often trips up new VirtualBox users is mouse capture: to release it from the VM window, hold down the right Ctrl key. If you downloaded a live CD image make sure to select the hard drive installation boot option, rather than booting the live image.Īnd that’s all you have to do for a basic new operating system installation.

On the File Location and Size screen allocate enough space to hold your installation, plus a good buffer for growth. A fixed-size is suppose to deliver a little faster performance, at the cost of tying up unused storage space.

On the next screen you have to choose a fixed or dynamically-allocated hard drive file. In the next two screens create a new virtual hard drive in VDI (VirtualBox disk image) format.

This memory will not be available to my host system (Kubuntu) when CentOS is running. If you’re installing a headless server with no graphics it’s enough, but if you want graphics then give it more, just as though you were doing a standalone installation.
