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

Provided are a method and device for online migration of a physical server. The method includes: (A) obtaining partition information of a disk, and sending the partition information to another physical server, wherein the partition information is information about partitions of the disk; (B) storing the partition information on the disk (C) control the operating system to enter a dormant state, so that the memory data is saved to the disk; (D) save the disk to the other physical server; The memory data stored on the disk and the address of the memory data on the disk are sent to the other physical server, wherein the physical server is always in a normal operating state when performing steps (A) and (B). According to the method and device, the service interruption time during the migration process can be effectively reduced.

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...
