Problems solved by technology

However, the above virtual machine migration process can only occur when the system administrator or VM perceives that the link between the VM and the EVB edge switch fails. When the user network accesses the VM, if there is a problem with the layer 2 network from the user network to the VM , the VM cannot be triggered in time to perform virtual machine migration, resulting in the interruption of the user network access to the VM service, and the service of the VM cannot be restored in time

Embodiment Construction

[0035] Aiming at the problems existing in the prior art, an embodiment of the present invention provides a VM migration method, which is applied to a data center network including a VM management center, an EVB edge switch, a VM, and a user network. Wherein, the VM is connected to the EVB edge switch, the VM is connected to the VM management center, and the EVB edge switch and the user network are connected through a large layer 2 network. Further, the user network refers to the user or company that leases the VM to provide services. The user network can be a device (such as a PC) or a network composed of multiple devices; Layer-2 technology network, the large layer-2 technology can be Trill (Transparent Interconnection of Lots of Links, transparent interconnection of multiple links), SPB (Shortest Path Bridging, shortest path bridge), Vxlan (Virtual Extended VLAN, virtual extended VLAN), etc. .

Abstract

The invention discloses a method and equipment for VM migration. The method comprises the following steps: a CFM is configured on a VSI (Virtual Station Interface) corresponding to a VM of an EVB (Edge virtual Bridging) edge switch; the VLAN (Virtual Local Area Network) of the CFM is a specified VLAN corresponding to the flow of the VM; when the EVB edge switch receives a CCM message sent to the VSI by equipment between the EVB edge switch and a user network, and when the specified VLAN is carried in the CCM message, a link between the EVB edge switch and the user network is determined to be normal; when the EVB edge switch does not receive the CCM message sent to the VSI by the equipment between the EVB edge switch and the user network within in a preset time, the link between the EVB edge switch and the user network is determined to be faulted, information of the link fault between the EVB edge switch and the user network is informed to the VM, and the VM informs a VM management center to trigger the VM, so as to perform virtual machine migration. In the embodiment, the VM can be triggered in time to perform virtual machine migration, and the interrupt for accessing VM service by the user network is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method and device for VM migration. Background technique [0002] In the EVB (Edge Virtual Bridging, edge virtual bridging) data center network, the VM (Virtual Machine, virtual machine) goes online and the network policy deployment process is as follows: figure 1 As shown, the process includes: (1) Create a VTDB (VSI Type Data Base, virtual server interface type database), according to the planning of the network strategy, the network administrator creates a VSI (Virtual Station Interface, virtual server interface) on the network management server Type database, specify the VSI Type version, VSI Type number, and each VSI Type corresponds to the network traffic policy; the database formed by the VSI Type version, VSI Type number, and network traffic policy is VTDB. (2) To create a VSI instance, the system administrator queries the VSI Type version and the co...
