Problems solved by technology

However, in this way of physical storage space, virtual machines cannot read and write on hosts with different access interface protocols.
For example, the first host uses an RDMA over Converged Ethernet (RoCE) interface to access the remote storage device, and the second host uses an Ethernet (XGE) interface to access the remote storage device. Since the access protocol interfaces are different , the virtual machine cannot access the physical storage space

Abstract

The invention relates to the technical field of information processing, in particular to a storage content access method and device, electronic equipment and a computer storage medium. The method comprises the following steps: when a virtual machine of a first host runs, obtaining a storage address of to-be-accessed storage content from a logic virtual disk loaded by the virtual machine; Wherein the storage address adopts a storage format defined by a first access protocol; And based on the obtained storage address, accessing the storage content of the virtual machine in a target storage device through a first access protocol interface. Through the storage content access scheme provided by the embodiment of the invention, the virtual machine does not need to directly access the real physical storage space, so that the access mode of the virtual machine to the real physical storage space can be shielded.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to a stored content access method, device, electronic equipment, and computer storage medium. Background technique [0002] A virtual machine refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Virtual machines can implement distributed storage by accessing physical storage space. The physical storage space can support multiple hosts and provide storage resources for multiple hosts and virtual machines on the hosts. [0003] At present, most virtual machines directly write files generated during operation into the corresponding physical storage space through the bound physical storage space, so as to realize access to the physical storage space. However, in this way of physical storage space, virtual machines cannot read and write on hosts with diff...
