VIRTUAL MACHINE ONLINE MIGRATION METHOD AND APPARATUS, DEVICE, AND COMPUTER READABLE STORAGE MEDIUM

摘要

A virtual machine online migration method and apparatus, a computer device, and a computer readable storage medium. The method comprises: receiving a data migration instruction sent by a source end, and obtaining a configuration file of the source end corresponding to the data migration instruction (S100); according to the configuration file, creating a second virtual disk which is the same as a first virtual disk in the source end (S200); after the second virtual disk is created, running a target virtual machine to determine a reading port of the first virtual disk (S300); and reading data to be migrated corresponding to the first virtual disk on the basis of the reading port, and writing the data to be migrated into the second virtual disk (S400). Online rapid migration of storage data of a virtual machine is implemented, reduction of the workload of a source end is effectively accelerated, and the migration efficiency is improved.
