Method, device and physical host for managing physical network card

Abstract

The embodiment of the invention relates to a method, a device and a physical host for managing a physical network card. One or a plurality of virtual network cards are created and have standard network card characteristics and operation interfaces; and the one or the plurality of virtual network cards are respectively related with all the function modules of the physical network card. The one or plurality of virtual network cards are managed so as to manage the physical network card, thus the differences of bottom hardware is shielded from the upper layer, unified interfaces and equipment types are provided, so that the efficient and unified management is facilitated, and furthermore, the utilization ratio of network resources is improved.

Description

technical field [0001] The invention relates to computer technology, in particular to a physical network card management method, device and physical host. Background technique [0002] Virtualization is a hot technology in the data center now. Its core significance is to help the data center and large workstations to improve the flexibility and responsiveness of the environment to a new level at a lower cost. [0003] Nowadays, the virtualization technology of CPU (Central Process Unit, central processing unit) and memory is developing rapidly, but the virtualization of IO (Input / Output, input and output) is relatively backward, which has become the performance bottleneck of the rapid development of virtualization technology. Many hardware manufacturers Different solutions are proposed and used for IO virtualization technology. Network equipment is an essential part of the server in the data center. In order to improve the virtualization performance of network equipment, so...
