Method for operating multiple operating systems and corresponding system and mobile equipment

Abstract

The invention relates to a method for operating multiple operating systems. The method comprises the following steps: operating a first operating system as a host operating system; starting a virtualization-supported virtual machine monitor program VMM on the host operating system; operating a second operating system on the VMM as a client operating system; selecting one of the first operating system and the second operating system as a foreground operating system and the other operating system as a background operating system to guarantee that the provided user experience is that the foreground operating system owns all input equipment and output equipment. The invention also relates to a corresponding system and mobile equipment.

Description

technical field [0001] The present invention generally relates to the field of computer operating systems, and specifically relates to a method for running multiple operating systems, a corresponding system and a mobile device. Background technique [0002] In recent years, mobile devices such as tablets and smartphones have gradually become the preferred computing, gaming, or audio-visual playback devices that people cannot do without in their daily lives. Unlike a PC, the operation of a mobile device is mainly based on a touch screen, with a small amount of physical keys such as a power key and volume + / - keys involved. Operating systems running on mobile devices include Android, IOS, and Tizen. Usually, a mobile device can only run a specific operating system, for example, an Android device can run an Android operating system and Android applications, but cannot run a Windows operating system and Windows applications. This greatly limits mobile device support for applic...

Problems solved by technology

However, due to various technical reasons, virtualization technology has not been applied to mobile devices such as tablet computers and mobile phones, which are mainly small-sized displays and touch screens.

These technical reasons include, for example: the screen is small, the host operating system does not support multi-window operation mode, or (in the case that the host operating system supports multi-window operation mode) displaying the output screen of the guest operating system in multi-window mode may affect the user experience. Inconvenient; the input and output devices of each operating system are inconsistent (for example, the Windows operating system generally has a Windows key, Android has a Home key and a return key, and IOS only has a Home key); switching is complicated; user experience is poor, etc.

Also, virtualization technology on mobile devices did not bring a smooth user experience due to the small memory and low processor frequency of mobile devices at the time
