Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

Abstract

A virtual machine thermal migration system comprises a management node, a source server, a target server, a PCIE switchboard and an SR-IOV network card, wherein the source server comprises a VM before thermal migration; the target server comprises a VM after the thermal migration; the source server, the target server, the management node and the SR-IOV network card are connected to physical ports of the PCIE switchboard respectively for communication; the management node is used for configuring the connection relationship of a VF module used by the VM before the thermal migration and the source server to a connection relationship between the VF module and the target server through the PCIE switch board; and the target server used the VF module to complete the thermal migration of a virtual machine through the PCIE switchboard and according to the connection relationship with the VF module configured according to the management node. By switching the abovementioned relationship, data packages are prevented from being lost during reception and transmission, and continuity of network service is ensured.

Description

technical field [0001] The present invention relates to the server field, and more specifically, to a system and method for live migration of a virtual machine. Background technique [0002] Server virtualization technology is a current hotspot, and the "hot migration (Live Migration in English)" technology of a virtual machine (Virtual Machine, abbreviated as VM) is a hotspot among virtualization technologies. Virtual machine live migration technology is mainly used in scenarios such as maintaining server load balance or virtual machine disaster recovery and backup. [0003] The virtual machine live migration technology refers to the complete preservation of the running state of the entire virtual machine, and at the same time, it can be quickly restored to another physical server. Ideally, after recovery, the virtual machine is still running smoothly, and the user will not notice any difference. [0004] In the prior art, there are various application solutions for live ...
