Under desktop cloud computing environment, the establishment and use of virtual machine have numerous different modes.One of which side
Formula is to create virtual machine based on virtual machine template.Unified virtual machine template is initially set up, is then created according to virtual machine template
Multiple identical virtual machines use so as to user.In such a situation, if virtual machine template is updated, then just need basis
New virtual machine template creates new virtual machine so that user uses.Now just need to create newly virtual for each user
Machine simultaneously deletes old virtual machine.The establishment and deletion work of whole virtual machine certainly will bring huge workload.
The invention discloses the virtual machine update method under a kind of cloud computing environment and system.Method based on the present invention
And system can carry out batch updating operation to a large amount of virtual machines established based on unified virtual machine template automatically, so as to significantly
Reduce the workload of operating personnel.Next performing in detail for one embodiment of the invention is described in detail based on flow chart
Journey.The step of being shown in the flow chart of accompanying drawing can hold in the computer system comprising such as one group computer executable instructions
OK., in some cases, can be with suitable different from herein although showing the logical order of each step in flow charts
Sequence performs shown or described step.
The purpose of the virtual machine update method of the present invention is to be automatically updated after virtual machine template is updated accordingly virtually
Machine.In an embodiment of the present invention, perform virtual machine update method to first have to judge whether virtual machine template is updated, such as Fig. 1
It is shown, perform the step in dotted line frame 192.Corresponding virtual machine is then updated after virtual machine template is updated.
Based on the correlated characteristic analysis to virtual machine template, in the present embodiment, the information of virtual machine template is divided into two
Major class.One kind is configuration information, and it includes the equipment such as the processor (CPU), internal memory, network card equipment information created needed for virtual machine
Information.Another kind of is disc information, and it, which is included, creates the number of disks needed for virtual machine and the data message on each disk.
Classification of the present embodiment based on Template Information constructs updates the data structure for virtual machine renewal.Update the data structure
In include configuration information and disc information for renewal.It is larger in view of the data volume of disc information, therefore at this
Updating the data for embodiment has used disk to update flag bit in structure, the flag bit of disk renewal is used to mark whether to enter
Row disk updates, and disk specific disc information required when updating is then with reference to the disc information of the virtual machine template after renewal.
In the present embodiment, first have to judge whether virtual machine template is updated, this will judge above-mentioned virtual machine template
Information whether change.When the information of above-mentioned virtual machine template changes, i.e., virtual machine template is updated, now
Need to be updated corresponding virtual machine.Judge whether the information of virtual machine template changes, first have to obtain virtual machine
The initial information (information before changing) of template.Therefore first have to perform an initialization step when virtual machine more new system starts
Suddenly.In the present embodiment, in the last of cloud computing platform management program start-up course, initialization step is performed, obtains virtual machine
The initial information of template, initialization update the data structure and the related memory for being used for virtual machine renewal.
As shown in figure 1, in initialization step, step S101 is performed for the configuration information of virtual machine template, obtains and works as
The configuration information of preceding virtual machine template is simultaneously saved in internal memory.
In the present embodiment, the disc information of virtual machine includes the data message on number of disks and each disk.Pin
To the disc information of virtual machine template, step S103 is first carried out, obtains the number of disks of current virtual machine template and is saved in
In internal memory.Disk snapshot is based on because the usual data volume of data message on disk is very big, therefore in the present embodiment come analysis of magnetic
The conversion of disk information.Step S102 is performed herein, and all disks of current virtual machine template are done with disk snapshot, and by snapshot
Specified location is saved in, the positional information of snapshot is stored in internal memory.
Following can performs the virtual machine template monitoring step in dotted line frame 192, monitors virtual machine template so as to sentence
Whether disconnected virtual machine template is updated.Because monitoring behavior should be carried out immediately, i.e., system will be monitored operation always.
In order to reduce system burden, the present embodiment employs successively progressive monitor mode, and monitoring first is easiest to the variable of monitoring, root
The bigger monitoring judgement aspect of amount of calculation is triggered step by step according to monitoring demand.So as to not influence the accurate of final monitoring judged result
The amount of calculation for the policer operation that system needs are always maintained at is reduced in the case of degree as far as possible.
In the present embodiment, it is to detect whether there is renewal operation first to judge whether virtual machine template is updated.This
In perform step S111, insert Hook Function, virtual machine template may be caused to change in editor, newly-built virtual machine template etc.
Hypervisor interfaces position insertion Hook Function.Following can performs step S112, Hook Function is monitored, so as to utilize
Monitoring to Hook Function judges whether that virtual machine template operates.
Whether the Hook Function that system constantly monitors setting is triggered.Then illustrate to work as when Hook Function is not triggered
The preceding virtual machine template that is not present operates, and then illustrates to there is currently virtual machine template operation when Hook Function is triggered, now holds
Row step S113, judge that operation performs success or failure, that is, judge whether the virtual machine template operation for triggering Hook Function is successful
Perform.
In the present embodiment, virtual machine template operation can be divided into renewal operation and template establishes two classes of operation.Renewal behaviour
Work is operated based on existing template, updates the relevant information of existing template, so as to generate required virtual machine template.Mould
It is then to establish brand-new virtual machine template that plate, which establishes operation,.The main object of the present invention is automatic after virtual machine template is updated
Update corresponding virtual machine.It can be appreciated that when virtual machine template operation is establishes new template operation, not to create
Virtual machine is corresponding with new template, next it is desirable that based on the new virtual machine of newly-established template establishment, therefore next
With regard to need not temporarily carry out virtual machine renewal operation.
Therefore in the present embodiment, just need to perform step S121, analysis when virtual machine template operation is successfully executed
Whether the particular content of virtual machine template operation is renewal operation so as to judge that virtual machine template operates, that is, judges whether to build
New template is found.When virtual machine template operation operates for renewal, i.e., user does not establish new template but based on existing
Template when being operated can perform Template Information comparison step, compare the front and rear Template Information of virtual machine template operation from
And judge whether virtual machine template is updated.
Compare and establish new template, operating procedure can be greatly reduced by being updated operation based on existing template, so as to subtract
Few workload.In order that obtain user possesses bigger range of choice, it is necessary to constantly be preserved in expansion system when calling template
Template quantity.Therefore in the present embodiment, when virtual machine template operation establishes operation for template, step S122 is performed,
New template is saved in sample form storehouse to call later.
After new template is saved, system next just need to new template monitor, so as to new template renewal after renewal by
The virtual machine that new template creates.Therefore in order to be monitored to new template, step S123 is also performed before new template is monitored,
The initial information of new template is preserved, i.e., similar step S101, S102 and S103 operation are performed for new template, by new samples
The configuration information update of template does disk snapshot into internal memory, to the disk of new samples template, and snapshot is saved in into specific bit
Put, the positional information of snapshot is stored in internal memory.
In the present embodiment, it is contemplated that user is also possible to establish out and original sample mould when establishing new sample form
Plate identical sample form.Therefore a secondary-confirmation step is also needed in step S121.I.e. by newly-built template with owning
Original template compares, and can just determine that virtual machine template operation is mould when newly-built template and all templates are inconsistent
Plate establishes operation and establishes new template.Certain, based on actual conditions, above-mentioned secondary-confirmation step can also be omitted.
Template Information has been divided into configuration information and disc information by the present embodiment.Therefore held first when Template Information compares
Row step S131, configuration information comparison step, compare the front and rear virtual machine template configuration information of virtual machine template operation so as to obtain
Take comparative result.System obtains the configuration information after renewal, and compared with the configuration information with being preserved in internal memory.Before renewal
During rear configuration information difference, step S132, the difference of the front and rear configuration information of contrast renewal and the part that will have changed are performed
It is saved in and updates the data in structure.Then step S133 is performed, the configuration information after renewal is all saved in internal memory simultaneously
The configuration information before the renewal preserved in internal memory is deleted so that the renewal performed next time judges.
When the configuration information of the virtual machine template before and after step S133 is finished or updated is identical, next will
Disc information comparison step is performed, compares the front and rear disc information of virtual machine template operation so as to obtain comparative result.In this reality
Apply in example, disc information is divided into the data message in number of disks and each disk.It can be appreciated that number of disks compares appearance
Easily analysis, therefore step S141 is first carried out, whether identical compare the front and rear number of disks of virtual machine template operation.If disk
Number is changed, then directly explanation disc information is changed.
To when number of disks does not change, then needing to perform step S142, disk snapshot is contrasted, more each disk exists
Whether the front and rear disk snapshot of virtual machine template operation is identical.In step S142, the mould after being operated first to virtual machine template
Plate disk does snapshot, and whether then contrast new snapshot identical with the snapshot that is obtained in step S102 before.If number of disks
Change or disk snapshot is different, then need to perform step S143, the disk updated the data in structure is updated and indicated
Position is labeled as.Then step S144 is performed, the old disk snapshot of specified location is deleted and new snapshot is saved in specific bit
Put.The positional information and number of disks information of snapshot in final updating internal memory.
Can performs step S150 after the completion of the contrast of disc information and configuration information judges all, judges whether to need
Perform renewal operation.In the present embodiment, it is to check that what is generated updates the data whether structure is empty.
The purpose of the present invention be to the virtual machine of renewal in need be updated automatically.Therefore when needs perform renewal behaviour
When making, first have to filter out the virtual machine for needing to update.In the present embodiment, virtual machine is created based on virtual machine template, such as
The virtual machine template that fruit is used to create virtual machine is updated, then the virtual machine being created based on the template before renewal is just needed
It is to be updated.Therefore need to perform step S160, virtual machine search step, when a certain virtual machine template is by more in the present embodiment
When new, the virtual machine that all virtual machine templates based on before renewal create is searched out.In the process, system is according to renewal number
All virtual machines using the virtual machine template are searched from database according to the virtual machine template numbering in structure.
Then can performs fresh information push step, based on the running status of virtual machine according to the virtual machine after renewal
The Template Information of template constructs and pushes virtual machine fresh information.In the present embodiment, virtual machine fresh information includes configuration more
Fresh information and disk fresh information.Different constructions and push strategy are taken for different virtual machine fresh informations.Cause
This fresh information push step and afterwards virtual machine renewal step be sequentially completed for each virtual machine.At circulation
Each virtual machine is managed, when all virtual machines are all disposed, then this renewal process terminates.
In fresh information pushes step, step S171 is first carried out in system, judges whether to need to update configuration information.When
When needing to update configuration information, step S172 is performed, is constructed according to the configuration information after renewal and pushes config update information.
Then step S173 is performed, judges whether to need to update disc information.Check the disk updated the data in structure
Flag bit is updated, if flag bit is yes, i.e., when needing to update disc information, step S174 is performed, according to the disk after renewal
Information structuring disk fresh information.Because disc information can not be updated when virtual machine is run, thus step S174 it
After need perform step S175, judge whether virtual machine runs.When virtual machine is currently running, then execution step S176, delay pushes away
Send until virtual machine is out of service.
In order to perform in step S176, the present embodiment just initializes a timer first in initial initialization step
And one block of timing push buffering area.Timer is used to inspect periodically buffer contents and system its dependent variable, to determine to be
No initiation push operation.Timing push buffering area is used to preserve the disk fresh information for being currently needed for delay push, including virtual
Machine numbering, virtual machine template numbering, the disk list of renewal.It is pointed out that the initialization step in the present embodiment, i.e.,
The initialization operation of information acquiring operation and above-mentioned timer, timing push buffering area in S101, S102 and S103 is only
Need to perform when virtual machine more new system just starts.
In step S176, the disc information updated the data in structure is compiled together with virtual machine numbering, virtual machine template
One record of number conduct is saved in timing push buffering area.In order to ensure the uniqueness of operation, timing is pushed in buffering area
Virtual machine numbering is unique, i.e., synchronization, a virtual machine can only have a record in timing pushes buffering area；When new
Record be sent to timing push buffering area during also untreated old record, then new record is override into old record, from
And avoid collision problem.
According to the timer interval pre-set, update module reads timing and pushed every the time interval set
Content in buffering area, every record of circular treatment, the virtual machine in every record are numbered, obtain virtual machine information and examine
Look into whether virtual machine is in running status, if virtual machine state is is currently running, this process terminates, otherwise initiate push simultaneously
This records in timing push buffering area is deleted after pushing successfully.
When virtual machine is out of service, then step S177, locked virtual machine is first carried out.Under locking state, virtual machine
Any operation can not be carried out.Then step S178 is performed, pushes disk fresh information.
It is last then step S181 can be carried out according to the config update information or disk fresh information that are pushed out (renewal is virtual
Machine disk) or step S182 (renewal virtual machine configuration).In the present embodiment, step S182 is first carried out.Step S182 both may be used
It can also be performed with that can be performed when virtual machine is out of service while virtual machine is run.In step S182, according to more
The difference of data type in new data structure body, call the virtual machine interface completion CPU hot plugs of bottom, internal memory online respectively
Distribution, network interface card hot plug etc. operate.
Next step S181 is performed, step 181 can only perform when virtual machine is out of service and perform step S181
When virtual machine can not be operated.In step S181, decided whether according to the disk renewal flag bit updated the data in structure
Disk is updated, need not such as be updated, then this step terminates；If desired for all disks of renewal, then deletion virtual machine, and according to more
Disc information in new data structure body, by the disk that all disk copies of virtual machine template are virtual machine.In order to ensure it
The read-write efficiency of his virtual machine, in the present embodiment, while the virtual machine for carrying out disk renewal is no more than 3.
