The embodiment of the invention discloses a virtual machine mirror image file processing method and device, equipment and a storage medium. The method comprises the steps of determining a target popularity level identifier of a target mirror image file based on an obtained mirror image access request; the popularity level being determined in advance based on the number of virtual machines accessed to the mirror image file; determining a target storage queue of target data information of the target mirror image file based on the target popularity level identifier, and storing the target data information in the target storage queue; and based on the target storage queue, determining that the target storage position of the target mirror image file is the high-speed access space of a disk or a virtual machine host, and reading the target mirror image file from the target storage position. According to the method, the popularity level of each mirror image file is determined before the mirror image files in the disk are accessed, and different reading strategies are adopted for the mirror image files with different popularity levels, so that the cache preheating time is shortened, the bandwidth resource consumption for reading the mirror image files is reduced, and the reading efficiency of the mirror image files is improved.
Description
technical field [0001] The present disclosure relates to the technical field of cloud computing, and in particular, to a method, apparatus, device and storage medium for processing a virtual machine image file. Background technique [0002] In the existing hyper-converged system, the read and write performance of a virtual machine is mainly determined by the performance of the underlying storage device. The current storage devices mainly use disks with low price and large storage space. However, because the disk uses mechanical devices to address and read and write, the read and write speed is very slow, which seriously affects the read and write performance of the virtual machine. [0003] In addition, multiple virtual machines running in the hyperconverged system are cloned based on the same virtual machine template image file, and these image files are stored in the disk of the host where the hyperconverged system is located. When the host is powered off and restarted, ...
