摘要： The present invention provides a virtual machine system and a method for sharing a graphics card amongst virtual machines. A VMM of the virtual machine system is provided with a resource-converting module, which converts data exchanged between a graphics card drive module of a GOS in the foreground and the graphics card based on a resource-converting table, and also intercepts accesses to the real graphics card by a GOS in the background and then responds to its operations on the graphics card. The VMM is further provided with a switching module, which alters a state of a VM based on a command for switching the VM, saves a graphics card state before the VM is switched to the background and restores the stored graphics card state to the graphics card when the VM is switched back to the foreground. Further, the GOSs each comprise a graphics card drive module corresponding to the real graphics card for accessing the real graphics card. The systems and the methods according to the present invention enable the GOSs to access the real graphics card, and also enable switching among a plurality of virtual machines.

摘要： The present invention provides a virtual machine system and a method of accessing a graphics card. The virtual machine system includes a VMM, an SOS and at least one GOS, and further includes a resource converting module for performing IO address converting on graphics card framebuffer accessing data from GOS(s) or mapping MMIO(s) to physical MMIO(s) of a graphics card based on a resource converting table, and sending the processed data to the graphics card; and a framebuffer allocating module for dividing a framebuffer resource of the graphics card into multiple blocks and allocating them respectively to corresponding GOS(s). The resource converting table(s) records correspondences between a resource allocation for the graphics card by SOS and a resource allocation for the graphics card by GOS(s). The framebuffer MMIO resource(s) allocated to the graphics card by GOS(s) is/are the framebuffer allocated to GOS(s) by the framebuffer allocating module.

摘要： 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.
