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

The invention relates to the technical field of cloud technologies, and discloses a virtual machine data migration method and device, computer equipment and a storage medium, and the method comprisesthe steps: virtualizing remote storage equipment into NVMe equipment after a virtual machine migration message is detected, transmitting the NVMe equipment to a virtual machine, creating the virtual equipment through a virtual intermediate layer, then, after it is detected that the NVMe equipment is offline, migrating virtualization software through the virtual equipment; when it is detected thatvirtualization software migration is completed, connecting new NVMe equipment to a target-end virtual machine, transmitting the new NVMe equipment to the target-end virtual machine, then matching theNVMe equipment with the new NVMe dequipment to obtain a matching result, and when the matching result is consistent, completing virtual machine data migration. The invention also relates to a blockchain technology. The NVMe equipment is stored in the blockchain. According to the application, online migration of the virtual machine data is realized, so that the migration efficiency of the virtual machine data is improved.

Description

technical field [0001] The present application relates to the technical field of cloud technology, and in particular to a virtual machine data migration method, device, computer equipment and storage medium. Background technique [0002] Virtual machine hot migration requires only a short downtime during the hot migration process, which does not affect the normal operation of services on the virtual machine, and users will not obviously perceive the interruption of virtual machine services. For virtual machine live migration, reducing service interruption caused by network migration is an important factor for reducing downtime of virtual machine live migration. [0003] In the virtual environment, in the migration method of NVMe devices, the current method is to use the smart network card to virtualize the 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. However, this solu...
