Embodiment 1

[0033] This embodiment describes the embodiment of the present invention by using the operation process on the physical server side, please refer to figure 1 , figure 1 For the physical-to-virtual migration method provided by the embodiment of the present invention, the specific migration steps are as follows:

[0034] S11. Split the disk file into at least two differential files according to preset rules.

[0035] Specifically, first divide the disk of the physical server into at least two partitions according to preset rules, and correspondingly, the disk file is also split into at least two differential files, that is, the data stored in each partition is a differential document. Wherein, the preset rule may be to perform differential processing on the disk in a differential form, and divide the disk into at least two partitions. A unique identifier can be set in the differential file to ensure that the virtual machine can correctly reorganize the disk file according to ...

Embodiment 2

[0077] This embodiment describes the embodiment of the present invention by using the operation process on the virtual server side. A virtualization platform is deployed on the virtual server, and at least one virtual machine is deployed on the virtualization platform. This embodiment uses a virtual machine as an example for explanation. See Figure 6 , Figure 6 Another physical-to-virtual migration method provided by the embodiment of the present invention, the specific migration steps are as follows:

[0078] S61. Receive the differential file migrated from the physical server by taking the differential file of at least one partition as a migration unit.

[0079] Specifically, when receiving the differential files migrated by the physical server, it may be received one by one, or at least two differential files may be received at a time, and the specific number of received differential files is related to the number of differential files transmitted by the physical server ...

Embodiment 3

[0093] This embodiment is a device embodiment corresponding to Embodiment 1, and a physical server is provided. On the basis of Embodiment 1, this embodiment will not describe some content of the physical server in detail. For details, please refer to Figure 8 , Figure 8 A schematic diagram of a physical server provided in this embodiment, the physical server includes:

[0094] A file splitting module 81, configured to split the disk file into at least two differential files according to preset rules;

[0095] The file migration module 82 is configured to migrate the at least two differential files to the virtual machine by using at least one differential file as a migration unit.

[0096] Wherein, the file splitting module 81 is used for performing difference processing on the disk files to obtain at least two difference files.

[0097] Further, the physical server also includes:

[0098] A bandwidth monitoring module 83, configured to monitor network bandwidth before m...

Abstract

The embodiment of the invention discloses a method for physical-to-virtual online migration, a physical server, a virtual server, a system and a computer memory medium. A magnetic disk document is divided into at least two documents according to preset rules, wherein the at least two differential documents are migrated to a server with at least one differential document as the migration unit. In this way, reliability and efficiency of data migration are further enhanced; meanwhile, data can be migrated to the virtual server in real time; and thus data consistency in the whole migration is ensured.

Description

technical field [0001] The invention relates to the technical field of communications, and in particular to a physical-to-virtual migration method, a physical server, a virtual server and a system. Background technique [0002] In the current virtualization cloud platform scenarios based on KVM (Kernel-based Virtual Machine, kernel-based virtual machine) or XEN (open source virtual machine monitor), more and more users are interested in P2V (Physical to Virtual, physical to Virtual Virtual) migration puts forward higher requirements. [0003] The current processing method of mainstream manufacturers is that the P2V system first installs an agent on the physical server. The agent is used to generate a physical server disk snapshot, and calculate the physical server disk Create a virtual server of the same type, and finally copy the disk snapshot of the physical server to the virtual server and start the virtual server. This process requires that the network bandwidth is lar...
