Abstract

A configuration method of a block storage device of a virtual machine comprises the following steps of initializing the block storage device of the virtual machine, allocating a real storage space of the preset storage proportion to the block storage device of the virtual machine, setting the alarm proportion and increment proportion by which the actual use storage space of the block storage device occupies the real storage space, monitoring the current proportion by which the actual use storage space of the block storage device occupies the real storage space, comparing the current proportion with the alarm proportion, and if the current proportion is equal to or larger than the alarm proportion, dynamically expanding the capacity of the real storage space of the block storage device according to the increment proportion and the storage proportion so as to obtain the storage proportion with the expanded capacity. The invention further provides a configuration device of the block storage device of the virtual machine. By means of the configuration method and configuration device of the block storage device of the virtual machine, the utilization rate of the storage space of the block storage device of the virtual machine can be improved.

Description

technical field [0001] The invention relates to the technical field of storage virtualization, in particular to a method for configuring a block storage device of a virtual machine and a configuration device for a block storage device of a virtual machine. Background technique [0002] A virtual machine (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. Storage virtualization is to provide highly available, flexible and secure storage services for virtual machines. Among them, block-level storage virtualization is a storage service that provides logical storage for virtual machines. This service abstracts the logical address of the block storage to the virtual machine, and the virtual machine can directly manipulate the addresses of these logical storage devices as if using real storage devices. At the implementation level, the service captures and pa...
