Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] There are two cloning modes for batch cloning. One is full cloning based on the source virtual machine, that is, the data of the source virtual machine is completely copied to the destination virtual machine. During the copying process, the destination virtual machine cannot be powered on and put into use. Only then can it be used. The other is linked cloning based on the source virtual machine, which distributes images through snapshots. The entire cloning process does not actually copy data and can be completed within a few seconds. The linked clone needs to be continuously linked with the original image, that is, when the target virtual machine does not overwrite the corresponding offset data, the offset data needs to be read from the source virtual machine. But there are certain defects in these two ways. ...

Abstract

The invention discloses a virtual machine cloning method, device and equipment and a computer readable storage medium, and the method comprises the steps: generating a plurality of first snapshot nodes based on an original mirror image of an original virtual machine, and detecting whether the breadth pruning of each first snapshot node needs to be carried out or not: if yes, determining a pruningnode and a plurality of separation nodes corresponding to the pruning node in the first snapshot nodes, combining the separation nodes into the pruning node, and determining a target clone mirror image based on a father node of the pruning node; releasing the connection relationship between the father node and the pruning node, and establishing the connection relationship between the clone virtualmachine corresponding to the pruning node and the target clone mirror image. Therefore, the phenomenon that all the virtual machines linked and cloned are affected due to the fact that a source virtual machine breaks down is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a virtual machine cloning method, device, equipment and computer-readable storage medium. Background technique [0002] At present, hyper-converged systems are more and more widely used in governments, enterprises, schools, etc., and play an important role in many production business systems. And as hyper-convergence moves from mass customers, customers pay more and more attention to the details of all aspects of the product. Financial customers often compete on the speed of cloning virtual machines. However, because the old version uses full cloning, it takes hours for large-capacity virtual machines, which is seriously insufficient compared to the second-level linked cloning of competitors. Moreover, although batch cloning is currently supported, since multiple images are cloned in full in serial, the problem of time-consuming batch deployment by users h...
