Network card direct connection system and data packet supervision method for virtualization platform

Abstract

The invention provides a network card direct connection system for a virtualization platform. The network card direct connection system comprises a virtual machine, a virtual network card, network data packets and a virtual switch, wherein the virtual machine is used for transmitting a network data packet, which is transmitted to an external network, to the virtual network card, and receives a network data packet, which belongs to the virtual machine and is from the external network, from the virtual network card; the virtual network card is used for forwarding the network data packet which belongs to the virtual machine to the virtual switch; the network data packets comprise the network data packet transmitted to the external network by means of the virtual machine, and the network datapacket which belongs to the virtual machine and is from the external network; and the virtual switch is used for forwarding the network data packet, which is transmitted to the external network by means of the virtual machine, to the external network, forwarding the network data packet which belongs to the virtual machine and is from the external network to the virtual machine by means of the virtual network card, and realizing supervision on the network data packet of the virtual machine. Therefore, the problem that the virtualization platform cannot perform flow control and supervision on the virtual network data packet when using network card direct connection is solved.

Description

technical field [0001] The present application relates to the field of computer networks, in particular to a network card pass-through system for a virtualization platform. The present application also relates to a data packet monitoring method for a virtualization platform. Background technique [0002] With the development of computer and Internet technology, virtualization technology has developed rapidly. A platform using virtualization technology (called a virtualization system or a virtualization platform) hides the actual physical characteristics of a specific computing platform. Multiple operating systems and applications can run on one platform, and each operating system and application can run on Access the required resources when needed, thereby providing users with an abstract, simulated computing environment (called a virtual machine). These virtual machines run in independent spaces without affecting each other, which significantly improves the performance of ...
