Problems solved by technology

In this way, when the network data sent by other devices to the virtual machine reaches the VTEP2 device, the VTEP2 device will send the network data to the VTEP1 device, but the VTEP1 device cannot find the virtual machine locally, and the network data cannot be sent to the VTEP2 device. Virtual machines, resulting in a high packet loss rate for transmitted data

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0030] An embodiment of the present invention provides a method for virtual machine migration, which can be applied to a VTEP device in an EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network).

[0031] Such as figure 1 As shown, the processing of the method may include the following steps:

[0032] Step 101, receiving a first update message sent by a first extensible virtual local area network tunnel endpoint VTEP device.

[0033] Wherein, the first update mes...

Abstract

Embodiments of the present application provide a method and device for migrating a virtual machine, which belong to the technical field of the Internet. The method includes: receiving a first update message sent by a first extensible virtual local area network tunnel endpoint VTEP device, the first update message carrying a first synchronous media access control MAC address and the first synchronous MAC address to which the first update message belongs. The first virtual switching instance VSI; find the first forwarding entry matching the first synchronous MAC address and the outgoing port of the first forwarding entry is an Ethernet port; bind the VLAN through the first VSI All Ethernet ports send the ARP request message; it is determined that the ARP response message with the first synchronous MAC address as the MAC address of the sending end has not been received within a predetermined period of time, and then the outgoing port of the first forwarding entry Modify it to connect to the VxLAN tunnel port of the first VTEP device. By adopting the invention, the packet loss rate of transmission data can be reduced.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a method and device for migrating a virtual machine. Background technique [0002] With the development of Internet technology, EVPN (Ethernet Virtual Private Network, Ethernet virtual private network) technology is more and more widely used. EVPN is a data center interconnection technology based on Overlay technology, which is usually applied in VxLAN (Virtual Extensible Lan, scalable virtual local area network). The EVPN network includes multiple VTEP (VxLAN Tunnel End Point, VxLAN tunnel end point) devices, and the VTEP devices may be transmission devices (such as switches). The VTEP device can be connected to a server, and one or more virtual machines can run in the server. A virtual machine can communicate with virtual machines or servers connected to other VTEP devices through the VTEP device. [0003] Based on different business requirements, virtual mach...
