Embodiment Construction

[0081] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. The terms "first" and "second" in the embodiments of the present application are used for description purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features.

[0082] Such as figure 1 As shown in , it is a schematic diagram of the virtualization structure on the host provided by the embodiment of the present application. The host computer is a physical server, and the bottom layer of the physical server is a hardware layer. The hardware layer mainly includes a central processing unit (CPU), a main memory (such as a random access memory (RAM), etc.), an auxiliary memory (such as a hard disk, etc.) ) and hardware resources such as network card ( figu...

Abstract

A method and device for improving the reliability of communication paths, so as to improve the reliability of virtual machine communication. The method includes: creating a second communication path of the virtual machine, where the second communication path can be used to transmit messages sent and received by the virtual machine; the virtual machine runs on a host device, and the host device includes a second A physical network card, the virtual machine sends and receives messages through a first communication path, and the first communication path includes a communication path directly connected between the virtual machine and the virtual function VF in the first physical network card; the The virtual machine monitors the states of the first communication path and the second communication path; when the first communication path fails, sends and receives messages through the second communication path.

Description

technical field [0001] The present invention relates to the technical field of information technology (Information Technology, IT), in particular to a method and device for improving reliability of a communication path. Background technique [0002] A virtualization technology can abstract physical resources of a host into a shared resource pool for use by a virtual machine (virtual machine, VM) running on the host. Multiple virtual machines running on a host can share the host's NIC to communicate with the external network. Network cards can be assigned to virtual machines through network card virtualization. Network card virtualization may adopt single-root input-output virtualization (Single-Root I / O Virtualization, SR-IOV) or multi-root input-output virtualization (MultiRoot Input / Output Virtualization, MR-IOV). [0003] When a network card supporting SR-IOV capability is used on the host, the physical port of the network card will virtualize at least one physical func...
