Abstract

The invention provides a live migration method of a virtual machine instance. The live migration method is applied to cloud service equipment. The cloud service equipment carries micro-service hardware, and the virtual machine instance comprises a virtual machine simulator process on the micro-service hardware and a virtual machine driver in an operating system kernel carried by the cloud service equipment. The method comprises the steps that in response to the situation that a to-be-migrated virtual machine instance meets a live migration condition, an operating system kernel obtains first operating data of the virtual machine instance in the operating system kernel carried by the cloud service equipment, and the first operating data is written into a preset memory space. And the virtual machine simulator process obtains second operation data of the virtual machine instance on the micro-service hardware and third operation data of the virtual machine instance in the memory space of the cloud service equipment, and reads the first operation data from the preset memory space. And the virtual machine simulator process sends the acquired operation data to the target cloud service equipment so as to migrate the virtual machine instance to the target cloud service equipment.

Description

technical field [0001] The embodiments of the present specification relate to the field of computer technology, and more particularly, the embodiments of the present specification relate to a method for live migration of virtual machine instances. Background technique [0002] This section is intended to provide a background or context for the embodiments of the present specification that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Cloud servers generally include virtual machine instances implemented on cloud server devices through virtualization technology. Through the virtual machine instance, various services of the cloud server can be implemented. These services usually need to be kept online in real time, so when the virtual machine instance needs to be migrated from the current cloud service equipment, these services cannot be interrupted.
