IO virtualization implementation system and method based on VMDq technology

Abstract

The invention provides an IO virtualization implementation system and method based on a VMDq technology. The IO virtualization implementation system comprises the following modules: a module M1 for improving hardware by adopting the VMDq technology; and the module M2 is used for carrying out IO virtualization through improved hardware. Based on a hardware-assisted I / O virtualization model, a traditional Ethernet controller structure is improved and innovated by adopting a VMDq technology, so that the Ethernet controller supports a virtualization function, and each PCIe channel (lane) in the Ethernet controller supports eight virtual machines to have exclusive network data receiving and transmitting paths, so that the Ethernet controller is more convenient to use. And the application of dozens of virtual machines can be operated on one server.

Description

technical field [0001] The present invention relates to the technical field of virtualization implementation, and in particular, to a system and method for realizing IO virtualization based on VMDq technology. In particular, it is preferably related to an implementation method for supporting IO virtualization based on VMDq technology in an Ethernet controller. Background technique [0002] In recent years of the 21st century, with the rapid rise of e-commerce, short video and search engines, a large amount of data needs to be stored and forwarded. The construction of cloud computing infrastructure presents enormous challenges. Virtualization is one of the core technologies in the construction of cloud computing infrastructure platforms. It abstracts into multiple virtual physical resources by means of time-sharing and simulation, and provides them to the upper layer for use through media such as the network, so that the existing physical resources can be fully utilized.

Problems solved by technology

[0002] In the last few years of the 21st century, with the rapid rise of industries such as e-commerce, short video and search engines, it is necessary to store and forward a large amount of data. The storage and forwarding of these data need to rely on cloud computing technology, so for Cloud Computing Infrastructure Construction Presents Huge Challenges

[0011] In view of the related technologies mentioned above, the inventor believes that the I / O device is completely simulated and virtualized, which has the advantages of good sharing and direct use of the original physical drive. It has problems such as low I / O efficiency; the paravirtualization model has significantly improved virtual I / O performance compared to the fully virtualized device, but it is necessary to write the corresponding front-end and back-end drivers for each device, and to modify the operation For non-open source systems such as Windows, the cost of development and daily maintenance is relatively large; based on hardware-assisted I / O virtualization, multiple functional interfaces provided by special hardware are interconnected with virtual machines to realize virtual machines and hardware devices Pass-through, so its virtual I / O efficiency is infinitely close to the original performance of physical devices, and it is undoubtedly the I / O virtualization technology with the most development potential
