Abstract

The invention provides a storage access method and device for a virtual machine, and the method comprises the steps: enabling a server to log in a storage service of a network disk distributed for thevirtual machine, obtaining an identifier of the network disk, and creating the virtual disk with the identifier of the network disk for the virtual machine based on the network disk. The virtual machine logs in the storage service of the network disk after starting the operation system based on the virtual disk; and then based on the identifier shared by the network disk and the virtual disk, determining that the storage access path of the virtual machine comprises the access path of the network disk and the access path of the virtual disk, the access path of the virtual disk being a main path, and the access path of the network disk being a standby path. And switching the access path of the network disk as a main path by the virtual machine after detecting that the server logs out of thestorage service of the network disk. Therefore, the virtual disk can be accessed only by occupying a small amount of server resources in the starting stage of the virtual machine, and the virtual machine directly accesses the network disk after the virtual machine is started.

Description

technical field [0001] The present application relates to the technical field of storage, and in particular, to a storage access method and device for a virtual machine. Background technique [0002] In a virtualization environment, there are generally two types of disks that can be used by a virtual machine: one is a virtual disk, and the other is a network disk. At present, each time a virtual machine accesses a virtual disk, it needs to establish a communication connection with the server through a virtual network card, and then the server accesses the corresponding virtual disk. The above access process requires a server to access the virtual disk, the access path is long, and more resources of the server are required. In order to shorten the access path and reduce the occupation of server resources, the virtual machine can directly log in to the storage service of the network disk to access the network disk. Specifically, the virtual machine can log in to the storage ...
