First be the configuration management of keeper to migration strategy.Keeper is configuration emigration strategy on decision package, article one, migration strategy comprises the migration action triggering condition and the execution of moving, trigger condition is used to the foundation determining whether to perform migration action, only meet the condition of pre-configured migration strategy in the result analyzed network data sended over analytic unit, the action of migration could be performed.The condition of migration strategy can be the network traffics in the unit interval between two virtual machines, ftp is such as used to transmit large files between two virtual machines, may also be the number of communications between two virtual machines in the unit interval, such as between two virtual machines carry out frequently data base read-write operation, also can be broadcast traffic of certain virtual machine etc.When the action of migration strategy moves if mainly comprising, by the virtual machine moved, and the object physical host moved to.Thus determine which platform virtual machine when where is moved to.Such as keeper can specify in morning 2:00-3:00 to the multiple stage physical host of the virtual machine (vm) migration to the same network segment that meet migration strategy condition, or on same physical host.
Migration strategy must carry out configured in advance by keeper on decision package.Keeper can configure many strategies, and every bar strategy has different priority, mates successively according to priority orders, if there is a tactful condition to be met, then perform corresponding action, if all policy conditions do not meet, then can not perform migration action.
Monitor collecting unit starts to monitor and gathers the network data of turnover virtual machine, and therefrom extracts key message, such as, extract the source IP of message, object IP, source MAC, object MAC, source TCP/UDP port numbers, object TCP/UDP port numbers, timestamp etc., is sent to analytic unit after gathering.
The summary information that analytic unit analysis collects, by analysis, extracts the information made a policy for decision package and sends to decision package.Data traffic, number of communications etc. that such as analytic unit can analyze sometime between section two virtual machines make a policy for decision package.
Decision package is made migration virtual machine according to the decision-making of keeper's configured in advance or is continued the decision of monitoring.If the network data of virtual machine meets the decision-making of configured in advance, then decision package notice performance element makes corresponding action, when is included in, and moves on which or which platform virtual machine to which or which platform physical machine.
Performance element performs the migration action that decision package sends over.Sometime by some or certain virtual machine (vm) migration in some or certain physical machine.
By above-mentioned steps, achieve the real-time monitoring to virtual machine network data, according to the migration strategy of monitor data and administrator configurations, realize the dynamic migration of virtual machine.
And for example, the specific implementation of technical solution of the present invention is as follows:

Migration strategy comprises transition condition and migration action.Transition condition can comprise the network traffics in the unit interval between two virtual machines, the number of communications in the unit interval between two virtual machines, certain virtual machine broadcast or multicast network flow etc. in the unit interval.Migration action can comprise in real time or in certain time period meeting the virtual machine (vm) migration of transition condition to where.Can by the multiple stage physical machine of the virtual machine (vm) migration to the same network segment that meet transition condition, or in same physical machine, thus shorten networking forward-path, reduce forwarded time delay, improve communication efficiency.
Second, realize monitor collecting unit function, this element needs to have the function of the network data of turnover virtual machine being carried out to collection analysis, and has the function to the data pick-up key message collected, here key message mainly refers to the content of TCP/IP header, such as the most frequently used source IP, object IP, source MAC, object MAC, source TCP/UDP port numbers, object TCP/UDP port numbers etc., and the message attribute information such as timestamp.These information package are sent to analytic unit by monitor collecting unit in batches.Therefore monitor collecting unit must can fast processing information, and the information gathered must be full and accurate.
3rd, Realization analysis Elementary Function, the key message of this element to the network data of the turnover virtual machine that collecting unit sends is analyzed, and then draw the input data made a policy for decision package, the data analysis that such as analytic unit can send according to collecting unit goes out has a large amount of data traffics to be sent to another virtual machine from a virtual machine in section sometime, or certain a section of time virtual machine receives the TCP connection of other a large amount of virtual machines, then these information can be sent to decision package by analytic unit, determine whether carry out virtual machine (vm) migration by decision package.
4th, realize performance element function, performance element mainly carries out final execution to the migration action that decision package issues, performance element can according to the migration action of decision package by virtual machine at the time-shift of specifying to certain physical host of specifying or multiple stage physical host.Before migration, performance element can check whether the object physical host moved to satisfies condition, whether such as CPU, internal memory, disk, Internet resources are enough, whether load transfinites etc., just can carry out the migration of virtual machine when physical host satisfies condition, and moves successfully and can inform decision package, decision package will record this time successful information of migration, and by corresponding migration strategy Disable, record migration strategy state is Success, shows that decision-making runs succeeded.If physical host condition does not meet, then performance element can every minor tick 30s, again attempt the action of 2 migrations, if run succeeded, then notify that decision package runs succeeded, and by corresponding migration strategy Disable, record migration strategy state is Success, if still cannot perform the action of migration, performance element can notify that decision package migration does not run succeeded.Decision package, also can by corresponding migration strategy Disable after receiving the failed notice of performance element migration, and record migration strategy state is Failure, records failed daily record, and notifies keeper by mail he.
By monitor collecting unit, the monitoring of turnover virtual-machine data and the collection of key message are extracted, with analytic unit, the information extracted is analyzed, decision package is according to the decision-making of predefined, the data of analysis are carried out decision-making, send the action allowing performance element specifically perform migration that performs an action, achieve the Autonomic Migration Framework of virtual machine, the network bandwidth and energy consumption are saved, reduce propagation delay time, raising business efficiency, transition process does not need manual intervention, improves O&M robotization, reduces business risk.
