To cut a hole the layer must have an alpha channel (ie supports transparency). jpeg format does not support transparency, png does. If the layer name is shown in bold it does not have an alpha channel. Right click on the layer and select Add Alpha Channel.
If the layer does not have an alpha channel: When you cut a hole the hole is filled with background colour, in your case white.
