Embodiment Construction

[0048] 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 only some, not all, embodiments of the present invention.

[0049] In a virtualized network environment, before data transmission between virtual machines, it is necessary to obtain the physical address of the other party for connection. Embodiments of the present invention provide a virtual machine communication method. Refer to figure 1 As shown, the method includes:

[0050] 101. The virtual switch receives a first broadcast packet requesting a virtual machine to send.

[0051] Wherein, the first broadcast message includes the IP address of the destination virtual machine, and optionally, the first broadcast message may be an ARP (Address Resolution Protocol, Address Resolution Protocol) message.

[0052] Before requestin...

Abstract

The present invention relates to the field of communications. Disclosed in an embodiment of the present invention are a virtual machine (VM) communication method and device, capable of reducing the number of broadcast packets in a virtual network. The method comprises: a virtual switch searches a stored address list for the MAC address of a destination VM according to the IP address of the destination VM; and if the MAC address of the destination VM is found, then obtaining the MAC address of the destination VM. The present invention is used for communication between VMs.

Description

technical field [0001] The present invention relates to the communication field, in particular to a virtual machine communication method and device. Background technique [0002] A virtual switch is a software-simulated switch in a virtualized network environment, and it is a key part of a virtual platform network. Generally speaking, in the OSI (Open System Interconnection, open system interconnection reference model) seven-layer model, a virtual switch takes the second The layer data link layer is mainly applied, and can complete the layer 2 network switching of the VM (Virtual Machine, virtual machine) in the server. Normally, the virtual switch will configure all the VLANs (Virtual Local Area Network, virtual local area network) used by the system. When a VM sends a broadcast message, the virtual switch will broadcast to all servers in the second layer data link layer. [0003] For example, in a virtualized network environment, VM1 and VM2 are virtual machines running o...
