Abstract

The invention provides a device dynamically switching equipment in a virtual environment and a method, wherein the equipment comprises a processing module which is used for receiving a moving-out command of a hardware equipment to be moved out, and simulating some moving-out or insertion events for the hardware equipment at a bottom layer through a virtual machine manager according to the moving-out command, or moving the hardware equipment from a first operating system to a second operating system through moving-out or insertion operation to the hardware equipment in each operation system through application programs, so that the hardware equipment can be used only by the second operating system. Due to the adoption of the technical scheme, all the operating systems of the computer can share the hardware equipment independently, thus the performance and the sharing property of the hardware equipment are ensured, and the hardware equipment can be switched among different operating systems.

Description

technical field [0001] The present invention relates to virtual machine technology in the field of computers, in particular to a method for dynamically switching devices in computers and virtual environments Background technique [0002] Common virtual machine architectures such as figure 1 As shown, it includes the hardware platform, the virtual machine manager (such as VMM, etc.) installed on the hardware platform, and multiple operating systems installed on the virtual machine manager, such as GuestOS1, Guest OS2, etc. The use of the device is managed and allocated by the virtual machine manager. In order to enable the device to be shared among multiple operating systems, the virtual machine manager often virtualizes a device for a certain operating system, such as installing a physical device on a hardware platform. Network card, if multiple operating systems need to use the physical network card, usually the virtual machine manager virtualizes a network card for each o...
