Abstract

Embodiments of the present invention provide a method and apparatus for accessing a storage device by a virtual machine in a cloud computing management platform. The method comprises: determining whether a storage device to be accessed by a virtual machine is located a same physical machine where the virtual machine is located; and if yes, directly mounting the virtual machine to the storage device. By means of the method and apparatus for accessing a storage device by a virtual machine in a cloud computing management platform provided in the embodiments of the present invention, the problem of the prior art is resolved in which a virtual machine cannot be directly connected to a local storage device and the connection must be performed by means of an iSCSI protocol.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a method and a device for a virtual machine to access a storage device in a cloud computing management platform. Background technique [0002] In a cloud computing system, a virtual machine reads and writes data by accessing a storage device in a storage network. Taking the cloud computing system using the openstack framework as an example, the computing nodes in it are connected to the storage devices in the storage network through the iSCSI protocol. figure 1 What is shown is a conventional architecture in which computing nodes are connected to storage devices provided in the prior art. Such as figure 1 As shown, each virtual machine located on physical machine A (computing node) must communicate with the iSCSI server in another physical machine B (storage node) through an iSCSI client, and further connect through the iSCSI server The corresponding storage device (phys...
