The embodiment of the invention provides a kind of resource allocation methods, and is as shown in Figure 1, comprising:
Step S101, virtual machine manager receive the current traffic performance information of managing business that virtualized each virtual machine reports respectively on first server.
Step S102, be that according to this traffic performance information each virtual machine distributes physical resource.
Among the above-mentioned steps S102, can at first analyze, determine resource allocation policy, and carry out the distribution of physical resource for each virtual machine according to the resource allocation policy of determining to each virtual machine to this traffic performance information that receives.
Below in conjunction with accompanying drawing, method provided by the invention and device and corresponding system are described in detail with specific embodiment.
The detail flowchart of the resource allocation methods that provides for the embodiment of the invention shown in Figure 2 specifically comprises:
The collection of step S201, traffic performance information with report.
Virtual machine is after starting operation; Confirm that its current encapsulation business is its current managing business, gather its current traffic performance information of managing business, this traffic performance information specifically can for its current relevant various information of managing business; As characterize the information of this virtual machine when the inherent characteristic of the business of pre-treatment; And the information of current situation to this business processing, for example, can be business process sign of service identification, each business process of being generated when handling this business etc.
After collecting traffic performance information, it is reported virtual machine manager.
In this step the collection of professional customizing messages and on call time, can be periodic triggering, also can be to set Event triggered; As in the starting stage of carrying out business processing; At first the reporting service sign in the interstage of business processing, reports the business process sign of each business process.
The analysis of step S202, traffic performance information.
Virtual machine manager is analyzed it after receiving the traffic performance information that each virtual machine reports, needed further information when determining follow-up definite resource allocation policy, for example:
According to the service identification in the traffic performance information, the corresponding relation of inquiry business sign and type of service is determined the pairing type of service of service identification, and this type of service is the current type of service of managing business of virtual machine.
Further can also the priority of every kind of type of service be set in advance according to service quality and demand characteristics professional in the reality, virtual machine manager then can inquire the priority of this type of service according to the type of service of determining.
The demand characteristics of each business process that can also be generated when managing business in the reality is provided with the priority of miscellaneous service process in advance, and virtual machine manager then can be determined business process and identified pairing priority according to the business process sign that reports.
Step S203, confirm resource allocation policy.
Virtual machine manager is based on the analysis of the traffic performance information separately that among the above-mentioned steps S202 each virtual machine is reported respectively; Determine resource allocation policy; Resource allocation policy confirm that can center on purposes such as QoS, energy-saving and emission-reduction, load balancing and resource optimization considers; Specifically can consider to confirm corresponding resource allocation policy from many aspects, as follows:
First kind of mode: consider type of service different service in the reality, its business demand characteristic maybe be different, for example: time delay demand, network bandwidth requirements, professional real-time demand, data storage requirement etc.; Be that type of service can indicate the business demand characteristic of specifying physical resource to certain; For example, type business is higher to the time delay demand in real time, so higher to the demand of cpu resource; Content class service is higher to the data storage demand, so more high to the demand of storage resources.
So; The embodiment of the invention proposes; Virtual machine manager can confirm the distribution priority of each virtual machine when distributing the appointment physical resource for each virtual machine, and definite resource allocation policy do according to the pairing type of service of the service identification in the traffic performance information; According to the distribution priority of each virtual machine,, each virtual machine specifies physical resource for distributing; Wherein, distribute Determination of priority specific as follows:
When specifying physical resource to be cpu resource; Confirm the distribution priority of the pairing type of service of the service identification that reports for real-time type of professional virtual machine, being higher than the pairing type of service of the service identification that reports is the distribution priority of the professional virtual machine of non real-time class;
When specifying physical resource to be storage resources; Confirm that the pairing type of service of the service identification that reports is the distribution priority of the virtual machine of content class service, be higher than the distribution priority that the pairing type of service of the service identification that reports is the virtual machine of non-content class service;
Business for other types; In like manner can be according to its concrete business demand characteristic; The distribution priority of making when specifying physical source distributing to other certain is confirmed rule, and by virtual machine manager according to this rule, when specifying physical source distributing to other certain; Determine the distribution priority of each virtual machine, be described in detail no longer for example at this.
The second way: virtual machine manager can also be according to the priority of the pairing type of service of service identification in the traffic performance information; Determine the distribution priority of each virtual machine; And definite resource allocation policy is to distribute physical resource according to the distribution priority of each virtual machine for each virtual machine.
Specifically can preestablish and distribute the Determination of priority rule to do; The distribution priority of the high more then corresponding virtual machine of the priority of type of service is higher; So; Virtual machine manager is according to this rule, and the distribution priority of the virtual machine that the priority of the pairing type of service of confirming to report of service identification is high is higher than the low virtual machine of priority of the pairing type of service of service identification that reports.
The third mode: the distribution Determination of priority mode of the virtual machine that proposes for above-mentioned first kind of mode and the second way; When the pairing type of service of service identification in the traffic performance information that different virtual machine reports respectively is identical; The distribution priority of then this different virtual machine being determined is identical, even consider that type of service is identical, but virtual machine possibly be different when the business of pre-treatment; So; The embodiment of the invention has also proposed for each identical virtual machine of the pairing type of service of the service identification that reports, and further distinguishes the scheme of distributing priority, and is specific as follows:
Mode A: consider that the business process that is generated when handling different service is different; So; Proposition is based on business process information; Further distinguish and distribute priority, specifically can preestablish the priority of each business process, distributing the Determination of priority rule is that the distribution priority of the high more then corresponding virtual machine of priority of business process is high more.Virtual machine manager is then according to this rule; Determine each identical virtual machine of the pairing type of service of the service identification that reports; Business process in the traffic performance information that reports respectively according to each virtual machine of confirming identifies pairing priority; Confirm that the business process that reports identifies the distribution priority of the high virtual machine of pairing priority, is higher than the distribution priority that the business process that reports identifies the low virtual machine of pairing priority.
In the embodiment of the invention, virtual machine can only report the business process sign of part main business process,, is further distinguished and distributes priority only according to the business process sign of this main process by virtual machine manager.
Mode B: propose the current resource utilization based on each virtual machine, further distinguish and distribute priority, concrete distribution Determination of priority rule is that the distribution priority of the high more then corresponding virtual machine of current resource utilization is high more.Virtual machine manager is then according to this rule; Determine each identical virtual machine of the pairing type of service of the service identification that reports; Current resource utilization according to each virtual machine of confirming; Confirm the distribution priority of the virtual machine that current resource utilization is high, be higher than the distribution priority of the low virtual machine of current resource utilization.
Wherein, the current resource utilization of virtual machine can initiatively report the Virtual Machine Manager server by virtual machine, also can determine the current resource utilization of each virtual machine by the resource operating position of each virtual machine of Virtual Machine Manager server monitoring.
In the embodiment of the invention; After determining the distribution priority of each virtual machine (the distribution priority of each virtual machine when comprising) to the appointment physical source distributing; Confirm that then resource allocation policy does, distribute physical resource (comprise and specify physical resource) for each virtual machine according to the distribution priority of each virtual machine, promptly can be according to distributing priority order from high in the end; For each virtual machine distributes physical resource, the preferential physical resource demand that satisfies the high virtual machine of distribution priority; Specifically can combine the current resource utilization of each virtual machine to distribute, as follows:
At first preestablish the corresponding setting resource utilization threshold value of each virtual machine,, confirm the physical resource amount of the current needs of each virtual machine according to the current resource utilization of each virtual machine and the magnitude relationship of corresponding setting resource utilization threshold value.
For example; Current resource utilization exceeds sets the resource utilization threshold value; Expression needs to increase the physical resource that distributes, and the physical resource amount that specifically need increase can be confirmed according to current resource utilization and the difference of setting between the resource utilization threshold value; Satisfy after increasing the physical resource that distributes, resource utilization does not exceed setting resource utilization threshold value and gets final product;
Current resource utilization does not exceed sets the resource utilization threshold value; Expression need not increase the physical resource of distribution; And, can also and set the difference between the resource utilization threshold value according to current resource utilization, confirm the unnecessary physics stock number that can provide; Satisfy after reducing the physical resource that distributes, resource utilization does not exceed setting resource utilization threshold value and gets final product.
After the physical resource amount of determining the current needs of each virtual machine, promptly can determine the physical resource amount of distributing to each virtual machine according to current needs physical resource amount, confirm that rule is the preferential physical resource demand of distributing the high virtual machine of priority that satisfies.The timing of concrete branch, virtual machine manager promptly can to the virtual machine of needs increase physical resource, be confirmed the physical resource amount that it need increase according to distributing priority order from high to low; To the virtual machine that need not increase physical resource, the physical resource amount that can keep distributing is constant; When the remaining physical resource of server is not enough, need to reduce the physical resource of virtual machine, so that when offering other virtual machine that need increase physical resource,, reduce the physical resource that virtual machine distributes according to distributing priority order from low to high.
In the embodiment of the invention,, propose to distribute the corresponding setting resource utilization threshold value of the high virtual machine of priority to be higher than the setting resource utilization threshold value of distributing the low virtual machine of priority for the setting of above-mentioned setting resource utilization.
Consider that the physical resource that a physical server can provide is limited; The not enough situation of physical resource possibly appear; The embodiment of the invention proposes; When traffic performance information, determine the physical resource that need be that each virtual machine distributes, when exceeding the physical resource that this first server can distribute according to each virtual machine; In each virtual machine, select the part virtual machine (vm) migration to second server, and distribute the resource allocation policy of physical resource for the virtual machine of not migration based on the physical resource that first server can distribute; And the physical resource that can distribute based on second server distributes the resource allocation policy of physical resource for the virtual machine of migration.
Preferable, when determining whether to move, it is also conceivable that whether the current distribution priority that can't satisfy the virtual machine of physical resource demand is higher than setting priority, if be higher than, then moves, otherwise does not move.
The concrete virtual machine of confirming migration, can adopt following scheme:
According to the distribution priority of confirming, selection distributes the low virtual machine of priority and migrates on the second server; Perhaps
The virtual machine that the physical resource that selection need distribute remains unchanged also migrates on the second server; Perhaps
According to the distribution priority of confirming, in each virtual machine that the physical resource that needs distribute remains unchanged, select to distribute the low virtual machine of priority and migrate on the second server.
In this step; Virtual machine manager can confirm that rale store is in the allocation strategy storehouse by predefined resource allocation policy; When confirming resource allocation policy, from the allocation strategy storehouse, obtain earlier resource allocation policy and confirm rule, and determine corresponding resource allocation policy according to this rule according to traffic performance information.
Step S204, carry out physical source distributing.
Virtual machine manager promptly carries out the distribution of physical resource according to this resource allocation policy behind the resource allocation policy of determining to each virtual machine.
After the distribution of carrying out physical resource, can also carry out record to resource allocation conditions, for follow-up relevant resources allocation provides corresponding reference data.
To understand the above-mentioned resource allocation methods that the embodiment of the invention provides in order being more convenient for, to describe through instantiation below:
Suppose on the server of an applying virtualization technology, to have disposed three virtual machines altogether, three virtual machines are respectively VoIP business, Streaming business and instant messaging when the business of pre-treatment.Through knowing that to the analysis of three current traffic performance information of managing business of virtual machine VoIP belongs to real-time service, time delay and treatment effeciency etc. are required can be set at high-grade business than higher; The Streaming business belongs to content class service, and than higher, but real-time is less demanding, can be set at the ordinary grade business for data storage and mutual requirement; Instant messaging is because its interaction data amount is less relatively, and its real-time requires lower, can be set at the inferior grade business.
According to the real-time characteristics of above-mentioned three kinds of business, determine resource allocation policy to cpu resource, for example:
In the starting stage of business processing, can determine the distribution priority of each virtual machine according to the priority of each type of service, promptly the priority of type of service is high more, and then the distribution priority of corresponding virtual machine is high more;
In the interstage of business processing, suppose that current is to handle the cpu resource that VoIP is professional, Streaming is professional and the virtual machine of instant messaging distributes to be respectively: 50%, 20% and 15%; And professional for VoIP, because the priority of itself is higher, and the utilization rate of determining its current C PU resource exceeded corresponding setting threshold, confirms as limit priority so will handle the distribution priority of the virtual machine of VoIP business; For Streaming business and instant messaging; Its separately the utilization rate of cpu resource all do not exceed corresponding setting threshold; But, be higher than the distribution priority of the virtual machine of handling instant message so confirm the distribution priority of the virtual machine that treatment S treaming is professional because the professional priority of Streaming is higher than the priority of instant messaging.
According to distributing priority order from high to low, be preferably and distribute the high virtual machine of priority to distribute its needed cpu resource, perhaps for distributing the high virtual machine of priority to distribute the higher cpu resource of shared total cpu resource ratio.For example: will be adjusted into 55% for the cpu resource of handling the professional virtual machine distribution of VoIP, the cpu resource that remains the professional virtual machine distribution of treatment S treaming is constant, and the cpu resource that will distribute for the virtual machine of handling instant messaging is adjusted into 15%.
