Abstract

The invention discloses a method, a device and a system for migration of virtual machines. The method includes: using a switcher to detect whether the quantity of the virtual machines connected with a first virtual machine hosting server to be smaller than a first threshold value or not; and when the quantity of the virtual machines is smaller than the first threshold value, using the switcher to request a virtual machine management server to migrate the virtual machines connected with the first virtual machine hosting server to other virtual machine hosting servers. By the aid of the method, the device and the system, the problem of packet loss possibly caused by a virtual machine migration mode in the related technology is solved, and services are guaranteed to be smoothly performed while energy consumption of data center network equipment is reduced.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a virtual machine migration method, device and system. Background technique [0002] Green energy saving is one of the core requirements of data center equipment. Research has shown that energy consumption accounts for about 50% of the previous network equipment investment. Therefore, the new generation of data centers need new breakthroughs in green energy saving. The virtual machine dynamic migration technology in the data center is mainly to achieve the robustness of the virtual machine business, but the strategy of considering the virtual machine migration in terms of comprehensive energy use can also bring benefits to the green energy saving of the data center. [0003] Data center network equipment (for example, switches) has an energy-saving technology EEE, which can enter an energy-saving state when there is no traffic on the port of the network device, so that the energy c...
