Abstract

The embodiment of the invention relates to the technical field of virtualization. The embodiment of the invention provides a virtual machine data exchange method. A to-be-sent first data packet of a first virtual machine in a source physical host is obtained; according to a correspondence relationship between multiple virtual machines in the source physical host and multiple virtual queue groups associated with the source physical host, a virtual queue group corresponding to the first virtual machine is determined as a target virtual queue group; the target virtual queue group is determined in a target virtual queue, and then a target physical queue mapping the target virtual queue group is determined; and the first data packet is sent through the target physical queue. The technical scheme of the invention can ensure the data switching efficiency of virtual machine to a certain extent. The embodiment of the invention also provides a data exchange device of the virtual machine, the physical host and the cluster system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data exchange method and device for a virtual machine and a physical host. Background technique [0002] After the generation of virtualization technology, usually a physical host includes multiple virtual machines (VM, Virtual Machine), and there is at least one physical network card containing multiple physical queues on the physical host, and the multiple virtual machines share For the network card resources of the physical host, each virtual machine can send and receive data through any physical queue of any physical network card on the physical host. This resource allocation method will cause some virtual machines to occupy a large number of physical queues to send and receive data packets. , other virtual machines cannot allocate a reasonable number of physical queues to send and receive data packets, resulting in that the data exchange efficiency of the vi...
