Embodiment Construction

[0089] See figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, its specific implementation steps are as follows:

[0090] Step 1: Realize the I / O virtualization module in the distributed virtual machine monitor system DVMM. The realization platform of the overall system is Lenovo Wanquan R510 server, and the processor is Xeon3230.

[0091] Step 2: The basic functional modules in the overall structure include: virtual machine exit, virtual machine entry, instruction analysis, master node determination, and I / O device model. The existing technologies used in the realization of these modules are: VT-x, DSM, XEN virtualization technology; the auxiliary technology is the communication mechanism across physical nodes on the bare metal.

[0092] Step 3: Implement three basic I / O access methods based on the above basic functional modules: non-memory I / O instructions, memory access I / O instructions, and DMA instructions. The main technical ...

Abstract

The invention provides a method for realizing the distributed I/O resource virtualization technology and provides a method for managing and using the distributed I/O resource virtualization technology effectively aiming at the limited factors that in recent years, the I/O resource management of large scale computer systems is complex, the using efficiency is low, and the like. The points of the invention are as follows: the I/O virtualization module in a distributed virtualization monitor system DVMM is realized; and the I/O virtualization module realizes cross-node access to three types of I/O instructions by the I/O virtualization technology, thus realizing the integration of the distributed I/O resource and providing a global virtual I/O environment for a client operating system. The invention explores a feasible path for the development of I/O technology in a future server.

Description

(1) Technical field [0001] The invention mainly relates to the field of I / O virtualization in computer virtualization technology. Mainly adopt the latest hardware and software virtualization technology to virtualize and integrate the I / O resources distributed in multiple hosts, build a global virtual I / O space for the upper guest operating system, and realize the distribution of guest operating systems. Global management and use of I / O resources. It belongs to the field of computer technology. (2) Background technology [0002] The key issue of virtualization is how to deal with sensitive instructions in the guest (Guest) operating system. Different virtualization methods adopt different processing methods. At present, there are three methods that are widely researched and used: [0003] Full-Virtualization (Full-Virtualization) method: This method provides a complete simulation of physical hardware, uses software simulation technology to process sensitive instructions, a...
