Specific implementation mode

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

To solve prior art problem, an embodiment of the present invention provides a kind of cloud host creation method and devices.Lower kept man of a noblewoman A kind of cloud host creation method is first provided for the embodiments of the invention to be described in detail.

It should be noted that the executive agent of scheme provided in an embodiment of the present invention can be scheduler, scheduler is used for Cloud host is created into task scheduling to physical machine, so that physical machine completes the establishment of cloud host.

Fig. 1 is a kind of flow diagram of cloud host creation method provided in an embodiment of the present invention, and this method includes：

S101 receives the request to create for target cloud host.

The quantity of target cloud host to be created, the type of target cloud host can be carried in request to create, are created and are somebody's turn to do The information etc. of the virtual ratio of the physical machine of target cloud host can also carry other information, the present embodiment certainly in request to create This is not limited.

S102 judges that first whether is carried in request to create is virtually compared label；If carrying first in request to create virtually to compare Label then executes S103.

Wherein, it first virtually is used to determine the destination virtual ratio for the physical machine for creating target cloud host than label, and has The destination virtual than physical machine first virtually compare tag identifier with this.

For example, if a user ask create a cloud host, and it is desirable that this cloud host create in specific object On reason machine, specific physical machine refers to that the quantity for the cloud host that can be at most created in this physical machine is no more than a certain particular value, This particular value can be referred to as virtually to compare.Most multipotency in the physical machine of virtual ratio is designated, and to create this virtual than corresponding Quantity cloud host.

In practical application, if virtual ratio is designated in a physical machine, can with virtually identifying the physical machine than label, For example, a physical machine is appointed virtual than being 3, then the virtual of the physical machine can be than label：ratio_3.Virtually compared The physical machine that label ratio_3 is identified can be understood as most multipotency in the physical machine and create 3 cloud hosts.

Label can be understood as that physical machine is marked with the form of keyword, to realize the classification to physical machine.It is real Border application in, physical machine by virtually than tag identifier the case where can be managed with tables of data.When a physical machine is not designated Virtually than when, it is corresponding virtually than label that tables of data does not record the physical machine, when the physical machine be designated it is a certain virtually than when, then According to specified, virtually than updating the data, the physical machine in table is corresponding virtually to compare label.Tables of data as shown in Table 1, physics Machine PM_1 be expert at corresponding " virtually than label " row be marked with virtually than label ratio_3, indicate that the physical machine is virtually compared Label ratio_3 mark, and physical machine PM_2 corresponding " virtually than label " row of being expert at are unmarked virtually than label, indicate this Physical machine is not compared tag identifier virtually.When judging whether with the physical machine virtually identified than label ratio_3, inquiry " virtually than label ", row whether there is label ratio_3 in tables of data.Tables of data can store in the scheduler, scheduler Select do not create cloud host and not by virtually than the empty physical machine of tag identifier as target physical machine after, by target physical Machine corresponding first is virtually stored than label into tables of data.

Table 1

Physical machine identifies	Virtually compare label
		PM_1	ratio_3
PM_2
		PM_3	ratio_4

It should be noted that when physical machine by one virtually than tag identifier after, this virtually than label be deleted before, The physical machine cannot again by others virtually be identified than label, but if this virtually than label be deleted after, the physical machine It can virtually be identified than label by others, that is to say, that a physical machine cannot be simultaneously by multiple virtually than label institute Mark.

The physical machine that virtually can be understood as specifying virtual ratio than the physical machine of tag identifier, is not compared label virtually The physical machine of mark can be understood as General Physics machine.It should be understood that the physical machine of virtual ratio is specified to belong to specified area, and it is general Logical physical machine belongs to public dispatch area, specifies the physical machine of virtual ratio and being isolated for General Physics machine, need not be by artificially drawing The physical isolation means such as subregion, but virtually reach nature isolation than label by identifying, this isolation method greatly subtracts Artificial intervention is lacked, need not manually be scheduled, to alleviate the workload of technical staff.

It should be understood that not all user has the demand of the virtual ratio of specified physical machine, those are not referred to Determine the ordinary user of the virtual ratio of physical machine, they can create not virtually than tag identifier cloud host to be created In physical machine, that is, create in the General Physics machine of public dispatch area.

Specifically, creating the request to create of cloud host, scheduler for the ordinary user of the virtual ratio of not specified physical machine The physical machine of establishment cloud host can be selected from General Physics machine；For each cloud host in request to create, creates and correspond to Cloud host create task, further according to the resource situation of resource and each General Physics machine needed for each cloud host, by cloud master Machine creates the establishment that task scheduling completes cloud host to one or more General Physics machine.

Specifically, the weighted value of each General Physics machine, physical machine can be calculated according to the resource service condition of physical machine Weighted value can be：The ratio of the used resource value of the physical machine and the total resource value of the physical machine, the smaller table of weighted value The surplus resources of bright physical machine are more, then, according to the weighted value calculated, are determined from General Physics machine and create cloud host Physical machine.For example, can randomly choose weighted value is less than the physical machine of default weighted value threshold value to create cloud host, it can also root According to the size of weighted value, preoption weight values small physical machines creates cloud host.It wherein, can be with when calculating weighted value Individually consider a certain resource of physical machine, such as disk residual capacity, memory, can also consider the group of multiple resources simultaneously It closes, the present embodiment does not limit this.

Further, if also taken in the request to create of ordinary user's establishment cloud host of the virtual ratio of not specified physical machine When cpu type with the physical machine for creating cloud host, then also need to from identified physical machine selection and meet cpu type to want The physical machine asked creates cloud host.For example, if the cpu type for carrying the physical machine for creating cloud host in request to create is 2680v4, then scheduler will be dispatched, cloud host establishment task to one or more cpu type will be 2680v4 and weighted value is expired On the General Physics machine required enough.

S103 is judged whether with first virtually than at least first physical machine for tag identifier, wherein the first object The quantity of reason machine medium cloud host is less than destination virtual ratio；If it does, S104 is executed, if it does not, executing S105.

S104 at least first physical machine will be determined as target physical machine；S106 is executed again.

S105 selects the first preset quantity platform not create cloud host and is not determined than the empty physical machine of tag identifier virtually For target physical machine, it is used in combination first virtually than the tag identifier target physical machine；S106 is executed again.

S106 creates target cloud host according to the request to create of target cloud host on target physical machine.

It should be understood that if virtually more current than in the physical machine of tag identifier to have created this first virtual with first Than corresponding quantity cloud host, then the physical machine cannot create other cloud hosts again.Therefore, if there is currently with first Virtually than the quantity of tag identifier and cloud host be less than destination virtual than the first physical machine, then can be directly by first object Reason machine creates target cloud host as target physical machine on the target physical machine；If there is currently no with first virtual Than the first physical machine of tag identifier, or exist by first virtually than the physical machine of tag identifier but physical machine medium cloud master The quantity of machine be equal to destination virtual ratio, then can first be selected from General Physics machine the first preset quantity platform do not create cloud host and Target physical machine is not determined as by the empty physical machine virtually than tag identifier, is used in combination first virtually than the tag identifier target physical Machine, then target cloud host is created on identified target physical machine.

It should be noted that the above-mentioned empty physical machine for not creating cloud host only indicates do not have cloud master in the current physical machine Machine, does not limit whether the physical machine once created cloud host, which can be the physics for never creating cloud host Machine, or once created the physical machine of the cloud host of ordinary user, and can also be once virtually to be crossed and worked as than tag identifier It is preceding not by virtually than the physical machine of tag identifier.

Specifically, the above-mentioned request to create according to target cloud host, creates the step of target cloud host on target physical machine Suddenly, may include：

The second physical machine for creating target cloud host is determined from target physical machine；

For each target cloud host in request to create, creates corresponding cloud host and create task；

The resource situation of resource and each second physical machine needed for each target cloud host creates each cloud host Build the establishment that task scheduling completes target cloud host to one or more second physical machine.

Specifically, the weighted value of each target physical machine, weighted value can be calculated according to the resource service condition of physical machine It is smaller to show that the surplus resources of physical machine are more, then, according to the weighted value calculated, is determined from target physical machine and create mesh Mark the second physical machine of cloud host.The weighted value of physical machine can be：The used resource value of the physical machine and the physical machine are total Resource value ratio.

For example, can randomly choose weighted value is less than the physical machine for presetting weighted value threshold value as the second physical machine, also may be used With according to the size of weighted value, the small physical machine of preoption weight values is as the second physical machine.Wherein, weighted value is being calculated When, it can individually consider a certain resource of physical machine, such as disk residual capacity, memory, can also consider a variety of moneys simultaneously The combination in source, the present embodiment do not limit this.

It should be understood that a request to create may need to create multiple target cloud hosts, each target cloud host pair A cloud host is answered to create task.In this case, due to the resource constraint of physical machine, such as disk residual capacity, memory money The resource in source, possible second physical machine cannot meet the needs of multiple target cloud hosts, therefore this multiple target cloud host It needs to create in one or more second physical machine, the resource needed for each target cloud host and each second physical machine Resource situation, cloud host establishment task scheduling is completed into the wounds of all target cloud hosts to one or more second physical machine It builds.

Further, if also carry the cpu type for the physical machine for creating target cloud host in request to create, also The selection from the second physical machine is needed to meet the physical machine of cpu type requirement to create target cloud host.For example, being asked if created It is 2680v4 to seek the cpu type of the middle physical machine for carrying and creating target cloud host, is appointed then scheduler will dispatch cloud host and create It is engaged in selecting cpu type in the second physical machine of 2680v4 to one or more.

Specifically, the resource situation of the resource and each second physical machine needed for the above-mentioned each target cloud host of basis, it will Each cloud host creates the step of task scheduling to one or more second physical machine completes the establishment of target cloud host, can wrap It includes：

Judge whether that can complete each cloud host creates task according to the resource situation of each second physical machine；

Target cloud is completed if it is, execute each cloud host creating task scheduling to one or more second physical machine The step of establishment of host；

If it is not, then the second preset quantity platform of selection does not create cloud host and not by virtually than the empty physical machine of tag identifier It is determined as the second physical machine, is used in combination first virtually than tag identifier second physical machine, then executes to create in each cloud host and appoint Business is dispatched to the step of one or more second physical machine completes the establishment of target cloud host.

For example, there is currently 5 the second physical machines, a request to create needs to create 10 target cloud hosts, if this 5 The resource of the second physical machine of platform can complete the establishment task of this 10 target cloud hosts, then directly create this 10 cloud hosts One or more in task scheduling to this 5 second physical machines is to complete the establishment of target cloud host.

Another situation, if the inadequate resource of this 5 the second physical machines is to complete the establishment of this 10 target cloud hosts Task is then needed first to select 1 empty physical machine for not creating cloud host to be determined as the second physical machine from General Physics machine, is used in combination First virtually than tag identifier second physical machine, then this 10 cloud hosts are created task scheduling to this 6 the second physical machines In one or more to complete the establishment of target cloud host.

Further, if the resource of this 6 the second physical machines is still not enough to complete the establishment of this 10 target cloud hosts Task then needs to select 1 empty physical machine for not creating cloud host to be determined as the second physical machine from General Physics machine again, and With first virtually than tag identifier second physical machine, until the resource of obtained second physical machine can complete this 10 mesh The establishment task of cloud host is marked, and then each cloud host is created in task scheduling to the second obtained physical machine.

In practical application, the value of above-mentioned second preset quantity and above-mentioned first preset quantity can be the same or different, The present embodiment does not limit this.

In one implementation, there is no do not create cloud host and not by virtually than the empty physical machine of tag identifier In the case of, it can also export there is no not creating cloud host and not by virtually than the prompting message of the empty physical machine of tag identifier. It should be understood that there is no do not create cloud host and not by virtually than the empty physical machine of tag identifier, that is, public dispatch area The lazy weight of middle General Physics machine, so that target cloud host creates failure, therefore exporting prompting message can be with reminding technology The inadequate resource of the public dispatch area of personnel, in order to which technical staff carries out resource adjustment or supplement.

In one implementation, for ease of the condition managing of physical machine and General Physics machine to specifying virtual ratio, also Can from physical machine whether by virtually than tag identifier, physical machine with the presence or absence of in terms of two, cloud host to the state of physical machine into Row is distinguished.

Specifically, the cloud host creation method can also include：

Whether according to current time physical machine each physics virtually is determined than tag identifier and with the presence or absence of cloud host The state of machine：

If physical machine is there are cloud host and by virtually than tag identifier, which is first state；

If physical machine is there is no cloud host and is virtually not up to preset time than the time that label is not deleted, the physics Machine is the second state；

If physical machine did not created cloud host and not by virtually than tag identifier, which is the third state；

If physical machine reaches preset time there is no cloud host and virtually than the time that label is not deleted, delete virtual It is determined as the third state than label, and by the physical machine.

It should be noted that for ease of recording the state of each physical machine, above-mentioned three kinds of states can be corresponded to one respectively A state value alloc_stat indicates that physical machine is in and uses for example, the corresponding state value alloc_stat of first state is 1 State, the corresponding state value alloc_stat of the second state are 2, indicate that physical machine is in the lock state, the third state is corresponding State value alloc_stat is 0, indicates that physical machine is in init state.In practical application, scheduler can be recorded and be updated The state value of the physical machine is updated to the shape after variation by the state of each physical machine when the state of physical machine changes The corresponding state value of state.

For example, at the beginning, when do not have in physical machine A cloud host and not by virtually than tag identifier when, physical machine A In the third state；Later, if physical machine A is selected as specifying the physical machine of virtual ratio and by virtually than label mark Know, then physical machine A is in first state, at this point, the state value of physical machine A is set to 1 by scheduler by 0, and is dispatching Device detects that the state value of physical machine A is 1 always there is no before cloud host in physical machine A；Then, if detected Cloud host is not present in physical machine A, the state value of physical machine A can be set to 2 by scheduler by 1, and physical machine A is in the Two-state, at this time in physical machine A there is no cloud host and not being deleted also than label virtually, and scheduler is by physical machine A State value at the time of be set to 2 by 1 timing, after reaching preset time, whether scheduler detects again deposits in physical machine A In cloud host, if there is cloud host, then the state value of physical machine A is set to 1 by 2, indicates that physical machine A can continue to make To specify the physical machine of virtual ratio, if there is no cloud host, then the virtual than label and by the physical machine of physical machine A is deleted State value be set to 0 by 2, indicate physical machine A by specify virtual ratio physical machine be changed into General Physics machine, from specified area return To public dispatch area.

As it can be seen that when the physical machine deficiency of the specified virtual ratio in specified area, virtually than tag identifier by way of, will be public The General Physics machine of dispatch area is changed into the physical machine of specified virtual ratio altogether, when not having cloud host in the physical machine for specifying virtual ratio When, it will be virtual than label deletion in the physical machine, so that it is turned again to public dispatch area as General Physics machine.It is this to be based on The physical machine resource dynamic management mode of label not only meets the demand that user specifies the physical machine of virtual ratio, while also real The resource-sharing in specified area and the physical machine of public dispatch area is showed.

It should be noted that after all cloud hosts are all deleted in the physical machine for specifying virtual ratio, physical machine is from first For state to the second state, the second state is a middle transition stage, also referred to as label pre-separation state, and at this moment physical machine is in Lock-out state, scheduler cannot dispatch this physical machine, i.e., in the second state, cloud host will not be created task tune by scheduler It spends in this physical machine.

It will be appreciated by persons skilled in the art that not having in the physical machine that one is specified virtual ratio if scheduler detects Have and just at once delete the virtual of the physical machine than label when cloud host, error is in this case likely resulted in, this is because cloud The high concurrent of host request to create, may occur in the short time the other cloud hosts of scheduler schedules create tasks to this Situation in physical machine, therefore this second state is arranged can be to avoid this problem.

It is above-mentioned to judge whether with the first virtual ratio mark in the case of the state of scheduler records and update physical machine Sign at least first physical machine for mark, wherein the quantity of the first physical machine medium cloud host is less than the step of destination virtual ratio, May include：

It obtains with first virtually than the physical machine of tag identifier, is determined as candidate first physical machine；

It will be in the physical machine of first state in candidate first physical machine, is determined as the first physical machine, wherein the first physics The quantity of machine medium cloud host is less than destination virtual ratio；

Judge whether at least first physical machine；

Above-mentioned selection the first preset quantity platform does not create cloud host and is not determined than the empty physical machine of tag identifier virtually For target physical machine the step of, may include：

The physical machine that the first preset quantity platform is in the third state is selected to be determined as target physical machine.

It should be understood that due in the physical machine of first state and the second state all in by virtually than the shape of tag identifier State, it is therefore desirable to which the state for first judging each candidate first physical machine, if it is first state, then first physical machine of candidate can To be determined as the first physical machine, cannot be scheduled if it is the second state since the physical machine of the second state is in the lock state Scheduled in device, therefore the first physical machine of candidate of the second state cannot be confirmed as the first physical machine.

As seen from the above, cloud host creation method provided in this embodiment, in the request to create for target cloud host Carry first virtually than label when, indicate that the user has the demand of virtual ratio of specified physical machine, if there is with first virtual Than the first physical machine of tag identifier, and the quantity of the first physical machine medium cloud host be less than destination virtual ratio, then by this first Physical machine is determined as target physical machine, and target cloud host is created on the target physical machine, if there is no with first virtual Than the physical machine of tag identifier, or exist with first virtual than the physical machine of the tag identifier still physical machine medium cloud host Quantity is equal to destination virtual ratio, then the first preset quantity platform is selected not create cloud host and not by virtually than the empty of tag identifier Reason machine is determined as target physical machine, is used in combination first virtually than after the tag identifier target physical machine, then on the target physical machine Create target cloud host.As it can be seen that scheme provided in this embodiment is for there is the wound of the virtual user than demand of specified physical machine Request is built, manual dispatching is not needed Auto-matching can be realized and virtually compare, automatically created in the physical machine of specified virtual ratio Cloud host reduces error.

Fig. 2 is the flow diagram of another cloud host creation method provided in an embodiment of the present invention, implementation shown in Fig. 1 On the basis of example, the first demand label can also be carried in the request to create, the first demand label is for identifying the user to wound Build the requirement of the physical machine of target cloud host；

Correspondingly, the step of above-mentioned S102 judges whether to carry the first user tag in request to create, Ke Yiwei：

S102a judges whether to carry first in request to create virtually than label and the first demand label；

Above-mentioned S103 judge whether with first virtually than at least first physical machine for tag identifier the step of, can Think：

S103a is judged whether simultaneously with first virtually than at least one of label and the first demand tag identifier One physical machine；

Above-mentioned S105 selects the first preset quantity platform not create cloud host and not by virtually than the empty physical machine of tag identifier Be determined as target physical machine, be used in combination first virtually than the tag identifier target physical machine the step of, Ke Yiwei：

S105a selects the first preset quantity platform not create cloud host and not by virtually than label and demand tag identifier Empty physical machine is determined as target physical machine, is used in combination first virtually than label and the first demand tag identifier target physical machine.

In practical application, there is specified physical machine virtually to also want to specifying the establishment of cloud host virtually than the user of demand Than and meet in the physical machine of particular requirement, wherein demand tag identifier can also be used by meeting the physical machine of particular demands.It is real It, can also be by a variety of different types of demand label marks by the physical machine virtually than the specified virtual ratio of tag identifier in the application of border Know.

For example, user has specified not only the virtual than being 3 of physical machine when creating cloud host, while also wanting to specific Cloud host is created in the physical machine of cpu type, at this point, can also be carried in request to create for identifying the physics for creating cloud host The demand label of the cpu type of machine shows this when it is cpu type label phy_cpu_2680v4 to carry the first demand label Request to create cloud host to be created must be 2680v4 and virtually than in the physical machine for 3 creating in cpu type, because The physical machine that this cpu type is 2680v4 can be used virtually than label ratio_3 and cpu type label phy_cpu_ simultaneously 2680v4 is identified.

Alternatively, when the type of service of the user is more, which also wants to create in the cloud host of identical services type It, then can be according to type of service to specifying the physical machine of virtual ratio to divide in identical physical machine.For example, request to create In can also carry for identify create cloud host physical machine type of service demand label, when the first demand mark of carrying When label are type of service label sub_user_A1, show that request to create cloud host to be created must created in business Type is in the physical machine of A1.The physical machine that type of service is A1 can be used virtually than label ratio_3 and type of service simultaneously Label sub_user_A1 is identified.

It should be noted that by virtually can be by a variety of different types of demand label marks than the physical machine of tag identifier Know, but cannot be by multiple same type of demand tag identifiers.For example, the physical machine that a cpu type is 2680v4 can be same When by virtually than label ratio_3, demand label phy_cpu_2680v4, demand label sub_user_A1 mark, but cannot Simultaneously by virtually than label ratio_3, demand label phy_cpu_2680v4, demand label phy_cpu_2680v3, demand mark Sub_user_A1 marks are signed, it can not be simultaneously by virtually than label ratio_3, demand label phy_cpu_2680v3, demand mark Sign sub_user_A1, demand label sub_user_A2 marks.It should be understood that phy_cpu_2680v3 and phy_cpu_ 2680v4 is to belong to same type of demand label, and sub_user_A1, sub_user_A2 are also to belong to same type of demand Label.

It, can also be according to the need of user in addition to the cpu type label and type of service label of the example above in practical application It asks the other types of demand label of setting, the present embodiment not to limit the quantity of the demand label entrained by request to create, such as creates A variety of demand labels can be carried simultaneously by building in request, can also only be carried a kind of demand label, be all reasonable.

In practical application, physical machine can be managed the case where demand tag identifier with tables of data.For example, when an object When reason machine is not by a certain demand tag identifier, tables of data does not record the corresponding demand label of the physical machine, when the physical machine is by certain When one demand tag identifier, the corresponding user tag of the physical machine is recorded in tables of data.Tables of data as shown in Table 1, physics Machine PM_1 be expert at corresponding " type of service label " row be marked with type of service label sub_user_A1, indicate the physical machine Identified by type of service label sub_user_A1, and physical machine PM_3 be expert at corresponding " type of service label " row do not mark Note has label, indicates that the physical machine is not identified by type of service label.When judging whether simultaneously with virtually comparing label When the physical machine of ratio_3 and cpu type label phy_cpu_2680v4 marks, by inquiring tables of data it is found that physical machine mark Know the physical machine for being PM_1 to meet the requirements.Tables of data can store in the scheduler, and scheduler does not create cloud host selecting And not by after virtually than the empty physical machine of label and type of service tag identifier as target physical machine, by target physical machine pair In the virtual storage to tables of data than label ratio_3 and type of service label sub_user_A1 answered, that is, with virtually than mark Ratio_3 and type of service label sub_user_A1 is signed to identify target physical machine.

Table 2

It should be understood that virtually have the demand of the virtual ratio of specified physical machine than tag identifier user, demand label into One step identifies user to other demands of the physical machine of establishment cloud host, virtually can will can be understood as one than label here Grade label, demand label are two level label, and the mode of this grade labelling meets a variety of demands of the user to physical machine, also just In the quick determining physical machine for meeting user demand.

It should be understood that physical machine can also reach the physical machine and other objects of the type by a certain demand tag identifier The isolation of reason machine also need not be manually scheduled when carrying a certain demand label in request to create, and scheduler can be by cloud Host creates task scheduling to by the physical machine of the demand tag identifier, and this isolation method based on label equally reduces people For intervention, the workload of technical staff is alleviated.

It should be understood that if there is currently with first virtually than the first physics of label and the first demand tag identifier Machine, and the cloud host number in the first physical machine is less than destination virtual ratio, then it can be directly using first physical machine as mesh Physical machine is marked, and creates target cloud host on the target physical machine；If there is currently no with first virtually than label and First physical machine of one demand tag identifier, or exist by first virtually than the physical machine of label and the first demand tag identifier But the quantity of the physical machine medium cloud host is equal to destination virtual ratio, then the first present count can be first selected from General Physics machine Amount platform does not create cloud host and is not determined as target physical machine by the empty physical machine virtually than label and demand tag identifier, is used in combination First virtually than label and the first demand tag identifier target physical machine, then creates target on identified target physical machine Cloud host.

It should be noted that the above-mentioned empty physical machine for not creating cloud host only indicates do not have cloud master in the current physical machine Machine, does not limit whether the physical machine once created cloud host, which can be the physics for never creating cloud host Machine, or once virtually crossed than label or demand tag identifier but current not by virtually than label or demand tag identifier Physical machine.

Specifically, requests to create of the S106 according to target cloud host, creates the step of target cloud host on target physical machine Suddenly, may include：

The resource situation of resource and each target physical machine needed for each target cloud host creates each cloud host Build the establishment that task scheduling completes target cloud host to one or more second physical machine.

Specifically, the weighted value of each target physical machine, weighted value can be calculated according to the resource service condition of physical machine It is smaller to show that the surplus resources of physical machine are more, then, according to the weighted value calculated, is determined from target physical machine and create mesh Mark the second physical machine of cloud host.The weighted value of physical machine can be：The used resource value of the physical machine and the physical machine are total Resource value ratio.For example, can randomly choose weighted value is less than the physical machine of default weighted value threshold value as the second physics Machine, can also be according to the size of weighted value, and the small physical machine of preoption weight values is as the second physical machine.Wherein, it is calculating When weighted value, it can individually consider a certain resource of physical machine, such as disk residual capacity, memory, can also consider simultaneously The combination of multiple resources, the present embodiment do not limit this.

If it is not, then the second preset quantity platform of selection does not create cloud host and not by virtually than label and demand tag identifier Empty physical machine be determined as the second physical machine, be used in combination first virtually than label and the first demand tag identifier second physical machine, The step that each cloud host is created to establishment of the task scheduling to one or more second physical machine completion target cloud host is executed again Suddenly.

In one implementation, there is no do not create cloud host and not by virtually than label and demand tag identifier In the case of empty physical machine, it can also export that there is no do not create cloud host and not by virtually than label and demand tag identifier The prompting message of empty physical machine.It should be understood that there is no do not create cloud host and not by virtually than label and demand label mark The empty physical machine of knowledge, that is, in public dispatch area General Physics machine lazy weight so that target cloud host create failure, Therefore output prompting message can be with the inadequate resource of the public dispatch area of reminding technology personnel, in order to which technical staff carries out resource tune Whole or supplement.

In one implementation, for ease of the condition managing of physical machine and General Physics machine to specifying virtual ratio, also It can be in terms of whether physical machine be by virtually than label and demand tag identifier, physical machine with the presence or absence of two, cloud host to physics The state of machine distinguishes.

Specifically, the cloud host creation method can also include：

According to current time physical machine whether by virtually than label and demand tag identifier and with the presence or absence of cloud host it is true The state of fixed each physical machine：

If physical machine is there are cloud host and by virtually than label and demand tag identifier, which is first state；

If physical machine than the time that label and demand label are not deleted there is no cloud host and when virtually not up to presetting Between, then the physical machine is the second state；

If physical machine did not created cloud host and not by virtually than label and demand tag identifier, which is third State；

If cloud host is not present in physical machine and the time not being deleted than label and demand label virtually reaches preset time, It then deletes virtually than label and demand label, and the physical machine is determined as the third state.

In practical applications, different attributes, including fixed attribute and recyclable attribute different labels can be arranged. Wherein, the label with fixed attribute does not delete the label when all cloud hosts in deletion of physically machine；And with recyclable The label of attribute deletes the label when all cloud hosts in deletion of physically machine.Label with fixed attribute is properly termed as solid Calibration label, the label with recyclable attribute are properly termed as variable label.

First illustrate the label with fixed attribute：For every physical machine, since the cpu type of physical machine is Determining, therefore the demand label of physical machine cpu type could be provided as the label of fixed attribute, for example, cpu type is The physical machine of 2680v4, after the physical machine is by demand label phy_cpu_2680v4 marks, when there is no clouds in the physical machine When host, demand label phy_cpu_2680v4 is not deleted.It should be understood that in fact, if deleting the need of the physical machine Label phy_cpu_2680v4 is sought, if subsequently needing to identify the physical machine with the demand label of physical machine cpu type again When, which still can be identified by demand label phy_cpu_2680v4.So for fixed labels, when being identified Physical machine in be not present cloud host when, can not be deleted.

The label with recyclable attribute is illustrated again：One physical machine can be by any virtually than label or any industry Therefore service type tag identifier virtually could be provided as the label of recyclable attribute than label and type of service label.For example, After one physical machine is virtually identified than label ratio_3, after cloud host is not present in the physical machine, virtually compare label Ratio_3 is deleted, in this way, the follow-up physical machine can virtually be identified than label ratio_4 by other, it can also be again by this Virtually identified than label ratio_3.Likewise, a physical machine is identified by type of service label sub_user_A1, when the business After type label sub_user_A1 is deleted, which can also be identified by other type of service label sub_user_A2, It can also be identified again by type of service label sub_user_A1.So for variable label, when the physics identified When cloud host being not present in machine, which should be deleted.

Therefore, it when while cloud host being not present in the physical machine of two variable tag identifiers, needs two variable marks Label are all deleted；Simultaneously be fixed in the physical machine of label and variable tag identifier be not present cloud host when, only delete can be changed label, Do not delete fixed labels.That is, in the state for determining physical machine, marked regardless of whether being fixed tag identifier or fixing Whether label are deleted, and only consider to can be changed label.

For example, at the beginning, when there is no cloud host in physical machine A and not by virtually than label and demand tag identifier When, physical machine A is in the third state；Later, if physical machine A is selected as target physical machine and is virtually compared label With demand tag identifier, then physical machine A is in first state, at this point, the state value of physical machine A is set to by scheduler by 0 1, and there is no before cloud host in scheduler detects physical machine A, the state value of physical machine A is 1 always；So Afterwards, cloud host is not present in physical machine A if detected, the state value of physical machine A can be set to 2 by scheduler by 1, should Physical machine A is in the second state, and cloud host is not present in physical machine A at this time and is not deleted also than label and demand label virtually It removes, and scheduler timing at the time of the state value of physical machine A is set to 2 by 1, after reaching preset time, scheduler It detects in physical machine A and is then set to the state value of physical machine A by 2 if there is cloud host again with the presence or absence of cloud host 1, indicate that physical machine A can continue then to delete the physical machine if there is no cloud host as the physical machine of specified virtual ratio The state value of the physical machine than label and demand label and is set to 0 by the virtual of A by 2, indicates physical machine A by specified virtual ratio Physical machine be changed into General Physics machine, return to public dispatch area from specified area.

As it can be seen that when the dedicated physical machine deficiency of a certain type in specified area, by virtually than label and demand label mark The General Physics machine of public dispatch area is changed into the physical machine of specified virtual ratio by the mode of knowledge, when the physics for specifying virtual ratio When there is no cloud host in machine, will be in the physical machine it is virtual deleted than label and demand label, make its as General Physics machine again It is secondary to return to public dispatch area.This physical machine resource dynamic management mode based on label not only meets user and specifies physics The demand of the virtual ratio of machine, while also achieving the resource-sharing of the physical machine between specified area and public dispatch area.

It should be noted that after all cloud hosts are all deleted in the physical machine for specifying virtual ratio, the physical machine is from the One state is changed into the second state, and the second state is a middle transition stage, also referred to as label pre-separation state, at this moment the object Reason machine is in the lock state, and scheduler cannot dispatch the physical machine, i.e., in the second state, scheduler will not create cloud host In task scheduling to the physical machine.

It will be appreciated by persons skilled in the art that not having in the physical machine that one is specified virtual ratio if scheduler detects Have and just at once delete the virtual of the physical machine than label and demand label when cloud host, in this case likely results in error, This is because the high concurrent of cloud host request to create, may occur the other cloud hosts of scheduler schedules and create in the short time Situation in task to this physical machine, therefore this second state is arranged can be to avoid this problem.

Scheduler records and update physical machine state in the case of, it is above-mentioned judge whether simultaneously use first virtually Than at least first physical machine for label and the first demand tag identifier, wherein the quantity of the first physical machine medium cloud host is small In the destination virtual ratio the step of, may include：

It obtains while with first virtually than the physical machine of label and the first demand tag identifier, is determined as candidate first physics Machine；

Judge whether at least first physical machine；

Above-mentioned selection the first preset quantity platform does not create cloud host and not by virtually than the sky of label and demand tag identifier Physical machine is determined as the step of target physical machine, including：

It should be understood that since the physical machine of first state and the second state is all in by virtually than label and demand label The state of mark, it is therefore desirable to the state for first judging each candidate first physical machine, if it is first state, then the candidate first Physical machine can be determined as the first physical machine, if it is the second state, since the physical machine of the second state is in the lock state, no It can be scheduled scheduled in device, therefore the first physical machine of candidate of the second state cannot be confirmed as the first physical machine.

As seen from the above, in scheme provided in this embodiment, first is carried in the request to create for target cloud host When virtually than label and the first demand label, indicate that the user has the demand of virtual ratio of specified physical machine, and the user wishes By target cloud host create meet particular demands, specify in the physical machine of virtual ratio, if there is with first virtual than mark First physical machine of label and the first demand tag identifier, and the quantity of the first physical machine medium cloud host is less than destination virtual ratio, First physical machine is then determined as target physical machine, and creates target cloud host on the target physical machine, if there is no With first virtually than the physical machine of label and the first demand tag identifier, or exist with first virtually than label and the first demand The physical machine of tag identifier but the quantity of the physical machine medium cloud host is equal to destination virtual ratio, then select the first preset quantity platform Cloud host is not created and target physical machine is not determined as by the empty physical machine virtually than label and demand tag identifier, is used in combination first Virtually than label and the first demand tag identifier target physical machine after, then target cloud host is created on the target physical machine. As it can be seen that scheme provided in this embodiment is for there is specified physical machine virtually than the request to create with the users of other demands simultaneously, Do not need manual dispatching can be realized specify virtual ratio physical machine in specific physical machine on automatically create cloud host, reduce Error.
