Description
Technical field
The invention belongs to field of network management, particularly relate to a kind of emigration processing method and system of virtual machine network control strategy.
Background technology
Virtual server significantly can promote server computational resource utilance, but has still only played a very little part for virtual advantage.The virtual extension to network enables virtual machine realize drift between physical server while application program is run, and provides capacity as required, without the need to increasing costliness and its platform to the greatest extent.The more important thing is, establishment and the movement of dynamic virtual machine allow keeper can respond rapidly new request, thus improve production efficiency and the customer satisfaction of user.But the network equipment traditional at present can not meet the demand of this dynamic migration, this becomes the bottleneck in virtualization process, and solves the real arrival that this bottleneck just means the virtual epoch.
Daily virtual machine (vm) migration is a kind of practical application of virtual-machine drift technology.When servers off-line carries out safeguarding or breaking down, virtual machine also can carry out the continuity of drift motion supporting business.In order to utilize these advantages, though the relevant network configuration of the virtual machine that drifts about between hardware platform uncomplicated, most important and very consuming time.In addition, when virtual machine in the data intracardiac drift time, the network layer strategy relevant to every platform virtual machine must drift about thereupon.These policy control the factor such as safety, service quality (QoS), and different from the concrete condition of user and application.Therefore, for each service application, to maintain the network strategy adapted most important for service operation.
Before virtual machine drifts to another from a physical server, associated network port configuration and security strategy must carry out correct setting for destination server, to meet demand for security.If data center exists a large amount of servers and virtual machine (vm) migration, so manual configuration can consume a large amount of time and resource.
