Problems solved by technology

However, for storage devices, the file system needs to be unmounted first, and then the file system must be remounted after the migration is completed. This cannot achieve real online migration, resulting in low migration efficiency.

Abstract

This application relates to the technical field of cloud technology, and discloses a virtual machine data migration method, device, computer equipment, and storage medium, wherein the method includes virtualizing the remote storage device into an NVMe device after detecting a virtual machine migration message, and The NVMe device is passed to the virtual machine, and the virtual device is created through the virtual middle layer. Then, when the NVMe device is detected to be offline, the virtualization software is migrated through the virtual device; The new NVMe device is connected to the machine, and the new NVMe device is passed to the target virtual machine, and then the matching result is obtained by matching the NVMe device with the new NVMe device. When the matching results are consistent, the virtual machine data migration is completed. This application also relates to blockchain technology, and NVMe devices are stored in the blockchain. This application implements online migration of virtual machine data, so as to improve the migration efficiency of virtual machine data.

Description

technical field [0001] The present application relates to the technical field of cloud technology, and in particular, to a method, apparatus, computer equipment and storage medium for migrating virtual machine data. Background technique [0002] The virtual machine live migration requires only a short downtime during the live migration process, which does not affect the normal operation of the services on the virtual machine, and the user will not notice the interruption of the virtual machine service. For virtual machine live migration, reducing the service interruption caused by network migration is an important factor to reduce the downtime of virtual machine live migration. [0003] In a virtual environment, in the migration method of NVMe devices, the current method is to use an intelligent network card to virtualize a remote storage device into a local NVMe device, and then transparently transmit the virtual NVMe device to the operating system OS of the virtual host. ...
