Step S101: controller receives the initiate notification that starts virtual machine;

Controller is the node of all virtual machines under a cluster of management, and controller is connected with boarding main frames all under cluster.Virtual machine is the virtualized computer system living with on boarding main frame.Boarding main frame is the computing machine in physical significance.A boarding main frame can mark off many virtual machines.Boarding main frame can perception lives with the behavior such as shutdown, startup of the upper virtual machine of this boarding main frame.Wherein, the starting state of the virtual machine that perceives of boarding main frame and while delaying machine state, using the starting state of virtual machine and the machine state of delaying as the special state of virtual machine, and sends the special state notice of virtual machine to controller.Therefore, step S101 can be specially: controller receives the special state notice of the virtual machine sending from boarding main frame, and special state comprises the starting state of virtual machine and the machine state of delaying.

Server is as the shadow node of virtual machine, and with cluster under the client of all virtual machine keep the relation of server client.Client, as a program of virtual machine inside, by the behavior of system interface perception virtual machine, and by the behavioural information of the virtual machine perceiving, sends to server.Because client is as a program of virtual machine inside, therefore, client can perceive than the more Zao step of boarding main frame the behavior of virtual machine.Server, by the behavioural information of the virtual machine obtaining, sends to controller.Therefore, step S101 can be specially again: controller receives the virtual machine sending from server and restarts notice.

Step S102: whether controller querying server exists the mirror image of virtual machine, if server exists the mirror image of virtual machine, enters step S103;

Step S103: controller respectively to server and boarding main frame send first migration instruction, first migration instruction be used to indicate server by the internal storage data single pre-copy of the mirror image of virtual machine to the main frame of lodging;

The mirror image of virtual machine is the copy of virtual machine on server, and on server, is moving the mirror image of this virtual machine, in brief, is moving the virtual machine the same with operating in the virtual machine of boarding on main frame on server.Certainly, server can also carry out internal memory compression to the mirror image of virtual machine, forms compressional mirror picture.

Single pre-copy is disposable (comprising the dirty data in internal memory) by the memory data copy of the virtual machine of boarding main frame to server.Server receives after the internal storage data of virtual machine, can be at server generating virtual machines.Wherein, controller, also can send carry instruction to boarding main frame, and the main frame that makes to lodge is virtual machine carry hard disk.

In embodiment of the present invention, after the initiate notification of controller sink virtual machine, instruction server to boarding main frame, recovers virtual machine by the internal storage data single pre-copy of the mirror image of virtual machine.Make the startup of virtual machine not need self the start-up course of experience at the generative process of boarding main frame generating virtual machines and virtual machine, the start-up time of effectively improving virtual machine.And the internal storage data of virtual machine is less, short to the time compole of boarding main frame from server pre-copy, do not have influence on start-up time of virtual machine.

Refer to Fig. 2, Fig. 2 is the process flow diagram that the present invention recovers method second embodiment of virtual machine.As shown in the figure, comprising:

Step S201: controller receives the first backup instruction from the backup virtual machine of server, and generate the second migration instruction according to the first backup instruction;

Virtual machine is the virtualized computer system living with on boarding main frame.Server is the shadow node of the virtual machine in cluster.Server can be the physical server of independent deployment, also can be the virtual server of virtual deployment, for example: by virtual machine form, provide server capability.Wherein, server and controller are in same levels, and server is connected with the maintenance of all virtual machines in cluster, and server can obtain IP address and the computer name of virtual machine.Further, server is according to IP address and the local mirror image that whether has virtual machine of computer name inquiry, if the local not mirror image of this virtual machine, after the information completing, sends the first backup instruction of backup virtual machine at the virtual machine activation that receives client transmission to controller.

Controller is for all virtual machines under management cluster, and is connected with the boarding main frame of virtual machine, by the lodge information of main frame of receptions, and the behavior of perception virtual machine, such as the startup of: virtual machine, shut down etc.In embodiment of the present invention, also can trigger module be set at controller, trigger module triggers the second migration instruction, wherein, the trigger point of trigger module can arrange according to truth condition, for example: restart or the automatic synchronization of starting shooting, manual synchronization, application amendment after synchronous, Timing Synchronization etc.The behavior that controller perceives virtual machine triggers the second migration instruction while meeting trigger point, such as: synchronous after application amendment,, for controller perceives the increase application program of virtual machine or reduces application program, controller triggers second and moves instruction.Therefore, step S201 also can be: the trigger module of controller triggers and generates the second migration instruction.

Step S202: controller sends the second migration instruction to the boarding main frame of virtual machine and server respectively, the second migration instruction be used to indicate boarding main frame by the internal storage data single pre-copy of virtual machine to server, with the mirror image at server generating virtual machines.

Boarding main frame is the physical host of operation virtual machine.A boarding main frame can move multiple virtual machines.Here single pre-copy is the virtual machine that refers to directly hang up boarding main frame, and disposable internal storage data (comprising dirty data) by the virtual machine on boarding main frame copies on server, the mirror image of generating virtual machines on server.The mirror image of virtual machine is to refer to moving the virtual machine the same with operating in the virtual machine of boarding on main frame on server.Certainly, server can also carry out internal memory compression to the mirror image of virtual machine, forms compressional mirror picture.

Step S203: controller receives the initiate notification that starts virtual machine;

Boarding main frame can perception live with all behaviors of the virtual machine of this boarding main frame, and the information perceiving is sent to controller.Wherein, when boarding main frame perceives virtual machine activation and delays machine, and the starting state of virtual machine and the special state of machine state as virtual machine of delaying, and send special state notice to controller.It should be noted that: boarding Host Detection is delayed after machine to virtual machine, notify controller except sending special state, boarding main frame also cuts out the virtual machine of the machine of having delayed by force.Step S203 can be specially: controller receives the special state notice of the virtual machine sending from boarding main frame, and special state comprises virtual machine activation state and the machine state of delaying.

Wherein, virtual machine will be restarted, but while not yet restarting, client perceives virtual machine by system interface and will restart.Than boarding main frame, client more early a step perception virtual machine restart behavior.If now, carry out the performance during rapid starting period of virtual machine at once, make the startup of virtual machine no longer need to experience unused time of virtual machine, the start-up time of further improving virtual machine.The information that the virtual machine of perception is restarted behavior by client sends to server.Server sends virtual machine to controller and restarts notice.Therefore, step S203 can be specially again: controller receives the virtual machine sending from server and restarts notice.

Step S204: whether controller querying server exists the mirror image of virtual machine, if server exists the mirror image of virtual machine, enters step S205;

Step S205: controller respectively to server and boarding main frame send first migration instruction, first migration instruction be used to indicate server by the internal storage data single pre-copy of the mirror image of virtual machine to the main frame of lodging;

Server to the main frame of lodging, recovers virtual machine on boarding main frame by the internal storage data single pre-copy of the mirror image of virtual machine.Wherein, controller also can send carry instruction to boarding main frame, and the main frame that makes to lodge is virtual machine carry hard disk.After boarding main frame is virtual machine carry hard disk, make virtual machine possess complete virtual machine function.Boarding main frame is that the hard disk of virtual machine carry can be the self-contained hard disk of boarding main frame, can be also the shared hard disk of network.

In embodiment of the present invention, indicate server the internal storage data single pre-copy of the mirror image of virtual machine to be arrived to the boarding main frame at virtual machine place by controller, on boarding main frame, recover virtual machine.Make the startup of virtual machine not need self the start-up course of experience at the generative process of boarding main frame generating virtual machines and virtual machine, the start-up time of effectively improving virtual machine.And the internal storage data of virtual machine is less, short to the time compole of boarding main frame from server pre-copy, do not have influence on start-up time of virtual machine.

Refer to Fig. 3, Fig. 3 is the process flow diagram of the 3rd embodiment of the present invention's method of recovering virtual machine.As shown in the figure, described method comprises:

Step S301: server receive self-controller first migration instruction, first migration instruction be used to indicate server by the internal storage data single pre-copy of the mirror image of virtual machine to the main frame of lodging;

Controller and server be the node in supervisory level all.Wherein, controller is connected with boarding main frames all under cluster, and under server and cluster, the client of all virtual machines keeps the relation of server client.

The mirror image of virtual machine is a copy that operates in the virtual machine on server.Server is the internal storage data of the mirror image of compressible virtual machine also, forms compressional mirror picture.If the mirror image of the virtual machine on server is compressional mirror picture, before the internal storage data single pre-copy of the mirror image of virtual machine is arrived to boarding main frame, also want this compressional mirror picture of decompress(ion).

Step S302: server according to the first migration instruction by the internal storage data single pre-copy of the mirror image of virtual machine to the main frame of lodging, with boarding main frame recover virtual machine.

Here single pre-copy is to refer to directly hang up the virtual machine on server, and disposablely copies the internal storage data of the virtual machine on server (comprising dirty data) to boarding main frame.The internal storage data single pre-copy of the mirror image of virtual machine, to the main frame of lodging, is directly recovered to virtual machine on boarding main frame.

In embodiment of the present invention, by the internal storage data single pre-copy of the mirror image of the virtual machine on server being arrived to boarding main frame, on boarding main frame, directly recover virtual machine, make the startup of virtual machine no longer need self the start-up course of experience at the generative process of boarding main frame generating virtual machines and virtual machine, the start-up time of effectively improving virtual machine.And the internal storage data of virtual machine is less, short to the time compole of boarding main frame from server pre-copy, do not have influence on start-up time of virtual machine.

Refer to Fig. 4, Fig. 4 is the process flow diagram of the 4th embodiment of the present invention's method of recovering virtual machine.As shown in the figure, described method comprises:

Step S401: server receives the connection request of self virtualizing machine, foundation is connected with virtual machine;

Server, as the shadow node of virtual machine, can, by virtual machine (vm) migration to server, move the mirror image of a virtual machine on server.Server keeps being connected with virtual machines all under cluster.。

Step S402: server obtains IP address and the computer name of virtual machine;

IP address and computer name form the unique identification of virtual machine.Can identify different virtual machines by IP address and computer name.

Step S403: server is according to IP address and computer name, and whether inquiry exists the mirror image of virtual machine, if do not have, enters step S404;

The mirror image of virtual machine is the virtual machine the same with operating in the virtual machine of boarding on main frame, and only the mirror image of virtual machine operates on server, as a copy that operates in the virtual machine on boarding main frame.

Step S404: server sends the first backup instruction of backup virtual machine to controller;

Controller is for all virtual machines under management cluster, and controller is connected with boarding main frames all under cluster.Controller receives after the first backup instruction, sends the second migration instruction respectively to the boarding main frame at server and virtual machine place.

Step S405: the second migration instruction that server reception is sent according to the first backup instruction by controller, the second migration instruction is used to indicate boarding main frame the internal storage data single pre-copy of virtual machine is arrived to server;

Boarding main frame receives after the second migration instruction, and the internal storage data single pre-copy of virtual machine is arrived to server.

Optionally, can trigger module be set on controller, trigger module is mainly used in backup virtual machine.When monitoring control devices arrives the trigger point of trigger module to the state of the virtual machine under cluster, trigger module triggers the second migration instruction, wherein, trigger point can arrange according to truth condition, for example: restart or the automatic synchronization of starting shooting manual synchronization, synchronous after application amendment, timing automatic is synchronous etc.The behavior that controller perceives virtual machine triggers the second migration instruction while meeting trigger point.Step S406: the second migration instruction that server reception is triggered by the trigger module of controller, the second migration instruction is used to indicate boarding main frame the internal storage data single pre-copy of virtual machine is arrived to server.

Optionally, virtual machine sends the second backup instruction of backup virtual machine to server.In embodiment of the present invention, backup button can be set on virtual machine, click backup button, virtual machine sends the second backup instruction to server, certainly, can also other modes trigger virtual machine and send the second backup instruction to server, for example: voice command etc.

Step S407: server receives the second backup instruction of the backup virtual machine of self virtualizing machine transmission;

Step S408: server sends the second migration instruction according to the second backup instruction to the main frame of lodging, the second migration instruction is used to indicate boarding main frame the internal storage data single pre-copy of virtual machine is arrived to server;

Step S409: server receives the internal storage data from the virtual machine of boarding main frame, and the mirror image of generating virtual machines;

Server receives after the internal storage data of virtual machine from boarding main frame, generating virtual machines on server, and this virtual machine is as the mirror image of virtual machine that operates in boarding main frame.And the mirror image of this virtual machine is carry hard disk not.

Step S410: server receive self-controller first migration instruction, first migration instruction be used to indicate server by the internal storage data single pre-copy of the mirror image of virtual machine to the main frame of lodging;

Controller can pass through to receive the information from boarding main frame, and knows the startup behavior of virtual machine.Whether controller querying server there is the mirror image of virtual machine, if there is the mirror image of virtual machine, sends the first migration instruction to boarding main frame and server respectively.

Further, if virtual machine is to restart action, than boarding main frame, virtual machine is the behavior of one step perception self morning more.And the message that virtual machine transmission virtual machine is restarted is to server, server is restarted virtual machine notice again and is sent to controller, controller is restarted notice according to virtual machine and is sent the first migration instruction to boarding main frame and the server of virtual machine respectively, and therefore, step S410 can comprise again:

Sub-step S4101: server receives the first message of self virtualizing machine, the first message is used to indicate virtual machine and restarts;

Sub-step S4102: server, according to the first message, sends virtual machine to controller and restarts notice, and sends to the boarding main frame of virtual machine the destruction instruction that destroys virtual machine;
