Abstract

The present invention provides a device control method and a computer, wherein the method includes: when detecting that an operating system accesses a device with a first type interface, preventing the operating system from accessing the first type interface through a virtual machine manager Controller access. The solution of the present invention prevents the operating system from accessing the controller of the first type of interface through the virtual machine manager, so that the first type of interface is disabled without causing potential safety hazards.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method for controlling computer equipment in a virtual machine environment and a computer. Background technique [0002] The security of using a computer installed with a virtual machine is concerned. Generally, in the process of using a computer, a USB (Universal Serial Bus, Universal Serial Bus) device is a frequently used device, but the USB device is unsafe, especially when using the USB device under a virtual machine architecture. [0003] Such as figure 1 As shown, it is a schematic diagram of the virtual machine architecture. The USB device plugged into the hardware device will have security risks during the use of the guest operating system (Guest OS) or the host operating system (Host OS). Therefore, it is necessary to install a virtual The USB interface of the computer of the machine is controlled; [0004] In the prior art, the filter driver of the USB device is a...
