Abstract

The invention provides a message processing method in a cloud computing system, a host, and a system. At least one network card is connected with the host, and the host is used for running of virtual machine monitor VMM, and the VMM is used for running of a first virtual machine. The VMM comprises a virtual network bridge and a virtual network function module. The network card comprises exchange equipment and at least network ports. The first network port is corresponding to at least one physical function PF and various virtual functions VF. The at least one VF of the first network port is directly connected with the first virtual machine. The first virtual machine is used to transmit data packets through the VF connected with the virtual machine, and the exchange equipment of the first network port is used to forward the data packets according to the target MAC addresses of the data packets, and the data packets are transmitted to the virtual network bridges of the VMM, and then the virtual network bridge is used to transmit the data packets to the virtual network function module. The virtual network function module is used to provide abundant virtual network function processing for the data packets. In a scene of network card direct connection, after the data packets are transmitted by the virtual machine via the directly connected VF, by adopting the above mentioned way, the data packets are used to redirected to the virtual network function modules of the VMM, and the software module is used to provide the abundant virtual network functions.

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...
