Problems solved by technology
[0010] It can be seen from the above methods that in the first method, once the external physical device is still used by GOS, it may cause damage to the physical device, while in the second method, the user needs to perform multiple operations, which is very cumbersome

Embodiment Construction
[0041] In a virtual machine system and a method for uninstalling a universal serial bus device according to the embodiment of the present invention, the HOS distinguishes the access type of the external device that needs to be used in the GOS, and when the external device is connected through the Dock device, the The external device is directed to a second emulated hardware device (set in the virtual machine) that emulates a second physical device that is accessed through a docking station and needs to be used in the GOS, and establishes a second emulated hardware device with a second emulated hardware device set in the GOS. The association relationship of the virtual docking station device in the GOS, when the HOS detects the Dock device unloading event, it notifies the GOS, so that the GOS unloads the virtual docking station device and the virtual docking station based on the association relationship. For the second simulated hardware device associated with the device, the PN...

The invention discloses a virtual machine system and a method for uninstalling docking station equipment in the virtual machine system. The virtual machine system comprises second analog hardware equipment used for simulating second physical equipment which is connected by the docking station equipment and is used in a guest operation system (GOS), a first directional module for directing the second physical equipment to the second analog hardware equipment, virtual docking station equipment, a differentiated system description table for recording the relation between the second simulation hardware equipment and the virtual docking station equipment, an event monitoring module for sending a notice to a virtual machine when the uninstalling request of the docking station equipment is detected, and an event simulation module for informing the GOS of a docking station equipment uninstalling event based on the notice so as to allow the GOS to uninstall the virtual docking station equipment and the second analog hardware equipment. In the invention, a user does not need to return to the GOS to manually uninstall, and simultaneously, the data damage problem caused by forced uninstalling is also sloved.
Description
technical field [0001] The invention relates to the field of virtual technology, in particular to a virtual machine system and a method for unloading a docking station device in the virtual machine system. Background technique [0002] Due to the limited layout of the external interfaces on the computer host, once there are many external devices that need to communicate with the computer host at the same time, there may be insufficient external interfaces, and this phenomenon is particularly apparent on notebook computers. [0003] In order to solve the above problems, many computer hosts can now provide a docking station (Dock) interface, through which an extended external device can be connected, wherein the external device includes USB (Universal Serial Bus, Universal Serial Bus) Devices, external display devices, COM devices, and printing devices. [0004] There are also handling mechanisms for Dock devices and Dock device unload events in the operating system design. ...
