Below in embodiment, be described in detail detailed features of the present invention and advantage, its content is enough to make any those skilled in the art to understand technology contents of the present invention and implements according to this, and according to the disclosed content of this instructions, claim and accompanying drawing, any those skilled in the art can understand purpose and the advantage that the present invention is correlated with easily.
The invention provides and a kind ofly go up to realize virtual machine at virtual platform (virtual host) (it is passed to a new virtual machine (new VM) in order to the current virtual machine (currentVM) that will serve a client for VirtualMachine, VM) Yi Zhuan method.Please refer to Fig. 1, it is the block schematic diagram of the virtual machine of one enforcement example according to the present invention.Can see by Fig. 1 and to know, comprise a virtual platform 22 in the resource pool 20, and have a virtual machine 24 to use on the virtual platform 22 for client 10.
Resource pool 20 comprises the actual computer hardware (being actual resource) that framework virtual platform 22 and virtual machine 24 are required, and virtual platform 22 and the virtual machine 24 creating out by these computer hardwares.In fact the computer hardware that needs can be an at least one property server with powerful arithmetic capability, also can comprise a jumbo storage device.Whole computer hardwares can be integrated in becomes a big virtual unit in the resource pool 20, and provides virtual machine 24 to use.And on real the work, also each the property server correspondence in the resource pool 20 can be configured to a virtual platform 22, and the virtual machine 24 that configuration needs on virtual platform 22.
Can be configured at least one virtual machine 24 on the virtual platform 22, and these virtual machines 24 are by the property server operation of framework virtual platform 22.Each virtual machine 24 all can have the virtual resource of oneself, uses to offer online client 10.Client 10 can be considered as online virtual machine 24 a common computing machine with processor and storage device, one operating system (Operating System, OS) 26 application programs miscellaneous (Application) and use it are installed in virtual machine 24.In other words, between the virtual machine 24 being can be mutually independently.Framework on same property server virtual machine 24 in addition different operating system 26 for example window (Windows) operating system or (SuSE) Linux OS can be installed.
Next the method that realizes the virtual machine transfer on virtual platform provided by the present invention will be described in detail in detail, how the current virtual machine of service client 10 be passed to new virtual machine with explanation.Please be simultaneously with reference to Fig. 2 and Fig. 3, it is respectively the schematic flow sheet of the method that realizes the virtual machine transfer on virtual platform of one enforcement example according to the present invention and the block schematic diagram of current virtual machine.
At first on ready property server, create (create also can be called framework) one first virtual platform 32 (step S50), and with first virtual platform, 32 establishing resource ponds 20 (step S60).First virtual platform 32 uses the actual resources running that property server provided, and with these actual resources then offer the virtual machine 24 of all frameworks on first virtual platform 32.In step S60, then the property server and first virtual platform 32 are set at resource pool 20 by first virtual platform 32.
After first virtual platform 32 is created, then add one second virtual platform 42 in resource pool 20, and in create on second virtual platform 42 new virtual machine 44 (step S70) and and on first virtual platform 32, create current virtual machine 34 (step S80), wherein current virtual machine 34 has an operating system 36 and a supervisory routine 38.That is to say that current virtual machine 34 and new virtual machine 44 system structures are on different virtual platform 22 (i.e. first virtual platform 32 and second virtual platform 42).Wherein but first virtual platform 32 and second virtual platform, 42 frameworks are in identical or different property server, and so preferably, first virtual platform 32 and second virtual platform, 42 frameworks are in different property server.
The operating system 36 of current virtual machine 34 can for example be all kinds such as Windows Server 2008, Ubuntu8.10 or Mac OS X Server, according to the present invention not to its restriction.Supervisory routine 38 then can be in order to actual resources all in the management resource pond 20 and according to the virtual platform 22 and the virtual machine 24 of actual resource institute framework.Therefore the client 10 that links to each other with current virtual machine 34 can see through the resource in the supervisory routine 38 management resource ponds 20.
Implement example according to of the present invention one, the method that realizes the virtual machine transfer on virtual platform can comprise in addition: see through the supervisory routine 38 of the current virtual machine 34 that runs on first virtual platform 32, the service of client 10 management resource ponds 20, first virtual platform 32 and second virtual platform 42 is provided.
In more detail, client 10 can see through supervisory routine 38 resource pools, 20 interior management or delete existing virtual platform 22, also can freely increase other virtual platform 22 newly.Identical, client 10 also can freely increase newly on each virtual platform 22, manage or deletion virtual machine 24.
In addition, (High Availability during HA) service, can move a trace routine in the arbitrary virtual machine 24 in current virtual machine 34 or resource pool 20 incessantly for the high availability that client 10 provided supervisory routine 38.Whether trace routine is necessary to transfer in order to the current virtual machine 34 that detects supervisory routine 38 places.For example, when having first virtual platform 32 of current virtual machine 34 or property server, framework need keep in repair or take place to need the current virtual machine 34 at supervisory routine 38 places is passed to framework in other virtual platform 22 or other property server when unusual.
Thus, trace routine just can be carried out transfer program (step S90) when the virtual resource at supervisory routine 38 places or actual resource generation problem, situation that can't use and management program 38 to avoid client 10 can't connect current virtual machine 34.Please refer to Fig. 4, it is the schematic flow sheet of the transfer program of one enforcement example according to the present invention.
After the detected program start, the transfer program is copied to new virtual machine 44 (step S92) with the data of current virtual machine 34.The transfer program is not only moved the file (data) in the virtual storage area of current virtual machine 34 to new virtual machine 44 totally, and the parameter or the related data that also operating system 36, supervisory routine 38 and all the other are run on the program of current virtual machine 34 are moved in the lump.Preferably, can see through in advance and use image file modes such as (image file), new virtual machine 44 is configured to and current virtual machine 34 identical environment.
Implement example according to of the present invention another, the new virtual machine 44 or second virtual platform 42 can be by the transfer program creations.That is to say that the new virtual machine 44 or second virtual platform 42 might not just be created before current virtual machine 34 offers client 10 with supervisory routine 38, also can need be carried out transfer and just create in current virtual machine 34.Because the structure of resource pool 20 can be considered a Internet (Internet) or a district net (Local Area Network, LAN), therefore can be according to an Internet Protocol address (the Internet Protocol Address of second virtual platform 42, IP Address) or a medium access control address (Media Access Control address, MAC address) create new virtual machine 44.Though by the new virtual machine 44 of transfer program creation or the mode of second virtual platform 42 slightly expends time in, relatively can reduce the redundancy (redundancy) in the resource pool 20.
The data of current virtual machine 34 are copied to after the new virtual machine 44 fully, and then the binding with 34 of client 10 and current virtual machine is copied to new virtual machine 44 (step S94).The binding that client 10 and current virtual machine are 34 means getting in touch between the supervisory routine 38 of client 10 and current virtual machine 34.This gets in touch normally based on network communication, for example comprises the Client-Server pattern, perhaps Web_Browser-Server pattern etc.Then in step S94, the binding that client 10 and current virtual machine are 34 is replicated to new virtual machine 44, and the binding of 34 of client 10 and current virtual machine is interrupted.In other words, next client 10 is obtained the service in management resource pond 20 by new virtual machine 44.
Transfer program at last stops current virtual machine 34, and starts new virtual machine 44 (step S96), then to provide service to client 10.And after carrying out the transfer program, the method that realizes the virtual machine transfer on virtual platform also can comprise: see through the supervisory routine 38 of the new virtual machine 44 that runs on second virtual platform 42, the service of client 10 management resource ponds 20, first virtual platform 32 and second virtual platform 42 is provided.
It should be noted that step S92 can still carry out in current virtual machine 34 when providing service to give client 10.Thus, just can in the shortest time, reach the transfer of current virtual machine 34, and be reduced to the image that client 10 is subjected to minimum to 44 of new virtual machines.
In sum, provided by the invention can be when taking place unusual or need keep in repair in the method that realizes the virtual machine transfer on the virtual platform, will provide the current virtual machine of the service of supervisory routine to be passed to new virtual machine on the different virtual platform automatically.Thus, the service that the user of client uses can not be interrupted, or of short duration acceptable interruption is only arranged.In addition, this service method of high availability that provides does not need redundant server, also need not use special backup software.Therefore with traditional method in comparison, can significantly reduce on the hardware and managerial cost.
