Abstract

The embodiment of the present invention provides a method, a host and a system for message processing in a computing system. At least one network card is connected to the host, a virtual machine monitor VMM runs on the host, a first virtual machine runs on the VMM, and the VMM includes a virtual network bridge and a virtual network function module. The network card includes a switching device and at least two network ports, the first network port corresponds to at least one physical function PF and a plurality of virtual functions VF, at least one VF of the first network port is directly connected to the first virtual function machine. The first virtual machine sends the data packet from the VF connected to the virtual machine, and the switching device of the first network port forwards the data packet according to the destination MAC address of the data packet, and sends the data packet to the virtual network bridge on the VMM, through The virtual network bridge transmits the data packet to the virtual network function module, and the virtual network function module provides rich virtual network function processing for the data packet. In the scenario of network card pass-through, after the virtual machine sends the data packet from the pass-through VF, the above method can redirect the data packet from the network card to the virtual network function module in the VMM, and use this software module to provide users with a rich virtual network Function.

Description

technical field [0001] The invention relates to the field of IT technology, in particular to a method, a host and a system for message processing in a cloud computing system. Background technique [0002] Virtualization technology is one of the key technologies in the field of cloud computing, which can abstract physical resources of a host into a shared resource pool for use by several virtual machines (Virtual Machine, VM) running on the host. Several virtual machines running on the host can share the network card of the host to communicate with the external network of the host. In the prior art, network cards can be assigned to virtual machines through network card virtualization, and network card virtualization can use single-root I / O virtualization (Single-Root I / O Virtualization, SR-IOV) or multi-root input Output virtualization (Multi Root Input / Output Virtualization, MR-IOV), the above network card virtualization is also called network card passthrough. Taking SR-I...
