Abstract

A method for establishing redundant connections for a virtual machine, which comprises: obtaining a plurality of storage nodes storing a same virtual machine image of the virtual machine; determining at least two storage nodes from the plurality of storage nodes, so that connections between a compute node provisioning the virtual machine and each of the at least two storage nodes have minimum correlation; and establishing connections between the compute node and the at least two storage nodes respectively. The present invention further discloses the corresponding apparatus.

Description

technical field [0001] The present invention relates to virtualization technology, in particular to a method and device for establishing redundant connections for virtual machines. Background technique [0002] In a distributed network such as a cloud computing network, there are generally two types of nodes, computing nodes and storage nodes. Computing nodes can provide the computing resources needed to install virtual machines, such as CPU and memory, while storage nodes can store and provide virtual machine images. In contrast to storage nodes, compute nodes are client devices. [0003] When installing a virtual machine on a computing node, it is necessary to load the virtual machine image to complete the initial configuration of the virtual machine system. Therefore, a connection needs to be established between the computing node and the storage node to transmit the virtual machine image. [0004] In the prior art, an Internet Small Computer System Interface (Internet...
