Embodiment Construction

[0025] The virtual machine system and the plug-and-play device dynamic allocation method of the present invention will be described below with reference to the accompanying drawings. Wherein, the same reference numerals represent units or modules with the same function.

[0026] Such as figure 1 Shown is the virtual machine system of the first embodiment of the present invention. The virtual machine system includes a server operating system 1 , at least one user operating system 2 , a virtual machine monitor 3 and hardware 4 . In the technical solution involved in the first embodiment of the present invention, since it only involves the process of switching from one operating system to another, that is, switching from servo operating system 1 to user operating system 2 or between user operating systems 2 In the switching process of the plug-and-play device (PnP Device), therefore, in this sense, the servo operating system 1 can be regarded as a user operating system 2, there...

Abstract

The invention relates supplies virtual machine system and dynamic allocation method for the plug and play device. The virtual machine system includes virtual machine monitor, and many operating systems. The virtual machine monitor includes plug and play module used to transmit generated interrupt signal to the corresponding operating system according to the call instruction, directly make the I / O operation act on the plug and play device by capturing corresponding operating system I / O operation, or according to plug and play standard specification, uses software to stimulate the I / O operation and feedback the result to the corresponding system to finish the processing indicated by the interrupt signal. The invention can realize full controllable dynamic resource allocation of the plug and play device without user participating, or rearrangement, staring up operation system.

Description

technical field [0001] The invention relates to a computer virtual technology, in particular to a virtual machine system and a method for dynamically allocating plug-and-play devices. Background technique [0002] The virtual machine system has a long history and has been firstly applied in mainframe and high-end server systems since the 1960s. In modern times, with the rapid development of personal computers, the application of virtual machine systems on personal computers is becoming more and more extensive. [0003] Currently, there are mainly three types of virtual machine systems on the market as shown in Table 1: [0004] Table 1 [0005] Types of feature typical representative host-based (Host-based) model The virtual machine system implemented by pure software, the virtual machine system needs to rely on A host operating system (Host OS) running VMWare and Virtual PC hybrid based (Hybrid-ba...
