Abstract
The present invention provides a control method for switching display between a plurality of OSs as well as a computer system. The method comprises: detecting that the currently displayed guest operating system (GOS) is required to be switched from a first GOS to a second GOS; determining whether the first GOS satisfies a preset switching condition, and switching the currently displayed GOS to the second GOS if the preset switching condition is satisfied, and otherwise, prohibiting the switching from the currently displayed GOS. With the method and the computer system, it is possible to avoid picture distortion or blurring or system collapse in switching display between a plurality of OSs.
