Embodiment Construction

[0028] see figure 1 , is a schematic structural diagram of a virtualization system provided by an embodiment of the present invention. The virtualization system includes a virtual resource manager 11 , multiple hosts 12 and a storage system 13 . The user device 14 accesses the virtual resource manager through the network, and creates a virtual machine on the host 12 through the virtual resource manager 11. Specifically, the user device 14 can access the virtual resource manager 11 in a direct or indirect manner, and the above-mentioned indirect method can be Log in to the virtualization system management server for the user equipment 14, and send an operation command to the virtual resource manager through the virtualization system management server.

[0029] The virtual resource manager 11 is used to send virtual machine operation commands to the host 12, including commands such as creating a virtual machine, starting a virtual machine, and deleting a virtual machine. The vir...

Abstract

The invention relates to a data replication method and device and a virtualization system. The method comprises the steps that after a virtual resource manager receives a mirror image export request of user equipment, a source book of a virtual machine and a target memory address of a mirror image file of the virtual machine are determined according to identification of the virtual machine carried by the export request, replication requests are sent to at least two determined hosts respectively, and all the hosts replicate different data segments of the source book of the virtual machine in parallel to the target memory address. In this way, in the mirror image export process, the virtual resource manager can assign multiple hosts to complete a data replication operation in parallel, the replication efficiency of the mirror image file is improved, and the performance bottleneck brought by the single host executing data replication is avoided.

Description

technical field [0001] The present application relates to the technical field of cloud computing, in particular to a data replication method, device and virtualization system. Background technique [0002] In the cloud computing scenario, with the emergence of virtual machine technology, cloud services have been applied on a large scale. A large number of customers are constantly moving their infrastructure to the cloud. In order to meet the growing demand of customers for cloud services, cloud service providers continuously add new servers to the server resource pool to support the normal operation of cloud services, and the virtual machines set on the servers provide cloud services. [0003] The prior art provides a method for creating a virtual machine using a mirror image. The system administrator sends a mirror image to create a virtual machine request on the console according to business requirements, and sets source mirror image, destination data storage and related ...
