Description

A kind of method of virtual machine (vm) migration
Technical field
The present invention relates to a kind of method of Virtual Machine Manager more particularly to a kind of methods of virtual machine (vm) migration.
Background technique
Virtual machine technique is common computer memory technical, but the needs upgraded since physical machine is subsequent, that First the virtual machine having existed in physical machine must move on other machines, then to corresponding physical machine into Row upgrading.
Simultaneously as virtual machine (vm) migration belongs to time-consuming operation (system disk data volume is bigger, and time-consuming is longer), existing operation is all Be separate unit physical machine is issued with CC (Central Controller, central controller) control, but AE (Agent Executor, Virtual level order executes agency) it can only handle a virtual machine (vm) migration task, the migration task that other front ends are sent is always etc. It stays in task queue, and front end is shown in migration.
Summary of the invention
In view of the above-mentioned problems, a kind of method that the present invention proposes virtual machine (vm) migration, comprising: send over all front ends Positive sequence sorts and is stored in database table A migration task in chronological order, and migration task status is set as " waiting " state；Root According to the source IP and destination IP searching database Table A of migration, and judge each IP of current source IP (Internet Protocol, Internet protocol) or destination IP whether belong to the IP migrated；If belonging to the IP in migration, new migration Task will not be handed down to AE processing；If it is determined that it is no, then it performs the following operations:
Whether the source machine and the current operand value of purpose machine for judging migration are greater than 0；If being not more than 0, then it is assumed that Inadequate resource returns to operation；
If it is greater than 0, then source machine numerical value and target machine numerical value respectively subtract 1, then whether target machine numerical value is judged Less than 1, if target machine numerical value, which less than 1, migrates task, will also come in task queue, AE processing will not be handed down to；Such as Fruit target machine numerical value is not less than 1, and target machine numerical value subtracts 1, then issues task and gives AE processing；
Migration task can be with timeout treatment: migrating task by setting time poll；If (when current time-migration starts Between)/1000 >=migration task migration duration, then migration task has timed, out；Otherwise continue poll.
Poll confirmation migration task has timed, out, and CC sends the inquiry of a current migration task status to AE, if worked as Preceding migration task is also being handled, then CC is returned；Otherwise CC sends a termination order and terminates current migration task to AE, AE, CC carries out corresponding rolling back action, terminates current migration task, and be set to failure handling.
Technical solution of the present invention realize the utility model has the advantages that
Effectively management virtual machine (vm) migration process, shorten the transit time of virtual machine so that physical resource obtain it is efficient and rational Utilization.
Detailed description of the invention
Fig. 1 is a kind of flow chart of the method for virtual machine (vm) migration of the present invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is further explained, and the embodiment of the present invention is only to illustrate this hair The protection scope that bright technical solution is not intended to limit the present invention.
A kind of method for proposing virtual machine (vm) migration such as Fig. 1, the present invention, comprising: the migration for sending over all front ends is appointed Positive sequence sorts and is stored in database table A in chronological order for business, and migration task status is set as " waiting " state；According to migration Source IP and destination IP searching database Table A, and judge whether current source IP or destination IP belong to the IP migrated；Such as Fruit belongs to the IP in migration, then new migration task will not be handed down to AE processing；If it is determined that it is no, then execute following behaviour Make:
Whether the source machine and the current operand value of purpose machine for judging migration are greater than 0；If being not more than 0, then it is assumed that Inadequate resource returns to operation；
If it is greater than 0, then source machine numerical value and target machine numerical value respectively subtract 1, then whether target machine numerical value is judged Less than 1, if target machine numerical value, which less than 1, migrates task, will also come in task queue, AE processing will not be handed down to；Such as Fruit target machine numerical value is not less than 1, and target machine numerical value subtracts 1, then issues task and gives AE processing；
Migration task can be with timeout treatment: migrating task by setting time poll；If (when current time-migration starts Between)/1000 >=migration task migration duration, then migration task has timed, out；Otherwise continue poll.
Poll confirmation migration task has timed, out, and CC sends the inquiry of a current migration task status to AE, if worked as Preceding migration task is also being handled, then CC is returned；Otherwise CC sends a termination order and terminates current migration task to AE, AE, CC carries out corresponding rolling back action, terminates current migration task, and be set to failure handling.

Claims (3)
