Embodiment Construction

[0033] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0034] figure 1 A flowchart showing a method for online migration of a physical server according to an exemplary embodiment of the present invention. Here, the physical server (hereinafter referred to as the source physical server) may be a physical server such as a physical machine or bare metal.

[0035] The method can be executed by the source physical server, and can also be realized by a computer program. For example, the method can be performed by a functional program in the source physical server.

[0036] Such as figure 1 As shown, in step S10, the partition information of the disk is obtained, and the partition information is sent to another physical server ...

Abstract

The invention provides an online migration method and device for a physical server. The method comprises the steps that 1, obtaining partition information of a magnetic disk, and sending the partition information to another physical server, wherein the partition information is related to partitions of the magnetic disk; 2, sending data stored on the magnetic disk and addresses of the data on the magnetic disk to another physical server; 3, controlling an operation system to enter the dormant state so as to store the internal storage data to the magnetic disk; 4, sending the internal storage data stored on the magnetic disk and the addresses of the internal storage data on the magnetic disk to another physical server, wherein when the physical server executes the steps 1 and 2, the physical server is in the normal operation state all the time. According to the method and device, the service interruption time in the migration process can be effectively shortened.

Description

technical field [0001] The present invention generally relates to the field of operating system migration, and more specifically relates to a method and device for online migration of an operating system for a physical server. Background technique [0002] Operating system migration, including offline migration and online migration. [0003] Offline migration: also known as static migration, refers to the migration of disk data when the operating system is shut down. [0004] Online migration: also known as real-time migration, hot migration, and live migration, refers to the migration of disk data and memory data while the operating system is running. This technology has been widely used in virtual machine scenarios, that is, virtual-to-virtual live migration (Virtual-to-Virtual live migration, V2V Live Migration for short). However, Physical-to-Physical Live Migration (P2P Live Migration for short) on the physical server is not yet mature. [0005] Virtual machine onlin...
