Based on above-mentioned communication system 400, the embodiment of the present application provides a kind of virtual machine creation method, as shown in fig.5, It the described method comprises the following steps：

S501：First client sends the request of the first virtual machine creating to control node.Wherein, the first virtual machine wound Build the first kind demand parameter for including the first virtual machine in request.

Correspondingly, the control node receives the first virtual machine creating request that the first client is sent.Described first is empty The first kind demand parameter of quasi- machine can be one or more.For example, the first kind demand parameter of first virtual machine is a ', Or the first kind demand parameter of first virtual machine is a ', b ' and c '.

Specifically, first client is the equipment that can be communicated with the control node, can be the control One in the node of node administration processed, it can also be server, can also be terminal device, such as personal computer, industrial personal computer Deng.

S502：The control node is according to the first kind demand parameter of first virtual machine, in multiple nodes of management The middle determining first object node for creating first virtual machine.

Wherein, the first kind demand parameter of first virtual machine meets the corresponding whole of the first object node first Class deployment conditions.That is, can only include and described first in the corresponding first kind deployment conditions of the first object node The matched first kind deployment conditions of first kind demand parameter of virtual machine.When the first kind demand parameter of first virtual machine is When N number of, the corresponding whole first kind deployment conditions of the first object node are up to N number of, and the first object node pair The first kind deployment conditions answered only include with the matched first kind deployment conditions of the first kind demand parameter of first virtual machine, N is positive integer.If the first object node is corresponding can to match described first simultaneously there are one first kind deployment conditions N first kind demand parameter of virtual machine, and the n first kind demand parameter can be only matched, then the first object The corresponding whole first kind deployment conditions numbers of node can be less than N, and 1 ＜ n≤N, n is positive integer；If the first object The corresponding first kind deployment conditions of node can only match a first kind demand parameter, then the first object node pair The whole first kind deployment conditions answered are N number of.

In specific implementation, when the first kind demand parameter of first virtual machine and the section of the control node management When the corresponding first kind deployment conditions of point use tag representation, due to judging that the first kind demand parameter of first virtual machine is The first kind deployment conditions of the no node for meeting the control node management are the first kind by judging first virtual machine Whether the corresponding label of demand parameter is consistent true with the first kind deployment conditions corresponding label of the node of the control node management It is fixed, if therefore the first kind demand parameter of first virtual machine when being N number of, the corresponding whole of the first object node First kind deployment conditions are N number of.

For example, the first kind demand parameter of first virtual machine is a ', then the first object node can only have With the matched first kind deployment conditions A ' of a ', there cannot be other first kind in addition to first kind deployment conditions A ' to dispose item Part, for another example, the first kind demand parameter of first virtual machine are a ' and b ', then the first object node can only have with The matched first kind deployment conditions A ' of a ' and and the matched first kind deployment conditions B ' of b ', cannot have except the first kind dispose item Other first kind deployment conditions other than part A ' and B '.

In implementation, the control node can determine in multiple nodes of management and create described the by following steps The first object node of one virtual machine：Determine multiple candidate nodes in multiple nodes of management, the of first virtual machine A kind of demand parameter meets the corresponding whole first kind deployment conditions of both candidate nodes；It is saved from the multiple candidate according to preset rules Selected in point one as the first object node.Wherein, the preset rules include but not limited to it is following any one or It is a variety of：The free memory of both candidate nodes is maximum, both candidate nodes processor occupancies are minimum, it is virtual to have been created in both candidate nodes Machine number is at least and the load number of both candidate nodes is minimum etc..

Optionally, the first virtual machine creating request also includes the second class demand parameter of first virtual machine, institute The the second class demand parameter for stating the first virtual machine meets some or all of described first object node correspondence the second class deployment item Part.That is, when the first kind demand parameter for not only having included first virtual machine in first virtual machine request, but also including When the second class demand parameter of first virtual machine, the corresponding first kind deployment conditions of the first object node can only include With the matched first kind deployment conditions of first kind demand parameter of first virtual machine, the first object node corresponding Two class deployment conditions include at least (described with the matched second class deployment conditions of the second class demand parameter of first virtual machine First object node can also have except the matched second class deployment conditions of the second class demand parameter with first virtual machine The second class deployment conditions in addition).Wherein, the second class demand parameter of first virtual machine can be one or more.

Specifically, when the N number of first kind demand parameter and M that in the request of the first virtual machine creating include the first virtual machine are a When the second class demand parameter, the corresponding whole first kind deployment conditions of the first object node are up to N number of, and described first Only include in the corresponding first kind deployment conditions of destination node and the first kind demand parameter of first virtual machine matched A kind of deployment conditions, as long as including and first virtual machine in the corresponding second class deployment conditions of the first object node The matched second class deployment conditions of M the second class demand parameters, i.e., the described first object node may include except with it is described The second class deployment conditions other than the M matched second class deployment conditions of the second class demand parameter of the first virtual machine, M, N are just Integer.

For example, when the first kind demand parameter for first virtual machine for including in first virtual machine creating request is A ', when the second class demand parameter of first virtual machine is a, the corresponding first kind deployment conditions of the first object node are only Can be and a ' matched first kind deployment conditions A ', the corresponding second class deployment conditions of the first object node include at least with The matched second class deployment conditions A of a；When the first kind for first virtual machine for including in first virtual machine creating request Demand parameter is a ', and the second class demand parameter of first virtual machine is a and b, the first object node corresponding first Class deployment conditions are only and a ' matched first kind deployment conditions A ', and corresponding second class of the first object node disposes item Part include at least with the matched second class deployment conditions A of a and with the matched second class deployment conditions B of b；When first virtual machine The first kind demand parameter for first virtual machine for including in request to create is a ' and b ', the second class of first virtual machine When demand parameter is a, b and c, the corresponding first kind deployment conditions of the first object node are only and the matched first kind of a ' Deployment conditions A ' and and b ' matched first kind deployment conditions B ', the corresponding second class deployment conditions of the first object node are extremely Include less with the matched second class deployment conditions A of a, with the matched second class deployment conditions B of b and with c matched second classes portion Affix one's name to condition C.

In implementation, when first virtual machine creating request also includes the second class demand parameter of first virtual machine When, the control node can determine in multiple nodes of management by the following method and create the of first virtual machine One destination node：(1) multiple candidate nodes are determined in multiple nodes of management, wherein the first kind of first virtual machine Demand parameter meets the corresponding whole first kind deployment conditions of both candidate nodes, and the second class demand parameter of first virtual machine is full The second class deployment conditions of some or all of sufficient both candidate nodes correspondence；(2) according to preset rules from the multiple both candidate nodes Select one as the first object node.

In conclusion the first virtual machine demand parameter carried in the first virtual machine creating request that the client is sent Including following two situations：(1) first kind demand ginseng of the first virtual machine only carried in the first virtual machine creating request Number；(2) first kind demand parameter and the second class demand ginseng of the first virtual machine carried in the first virtual machine creating request Number.Node due to that can create first virtual machine must have the first kind demand parameter with first virtual machine The first kind deployment conditions matched, and cannot have except the matched first kind portion of first kind demand parameter with first virtual machine Other first kind deployment conditions outside administration's condition, therefore, the control node determine in multiple nodes of management described in establishment When the first object node of the first virtual machine, first mesh can be preferentially determined from the node for having first kind deployment conditions Node is marked, so as to quickly determine the first object node, and then improves the establishment efficiency of the first virtual machine, and can be with Reduce the workload that the control node determines the first object node.

One specifically in embodiment, the control node can by the following method, in multiple nodes of management Determine multiple both candidate nodes：(1) the corresponding deployment conditions of multiple nodes of the control node management are obtained；(2) remove Do not have the node of first kind deployment conditions in the multiple node；(3) by the first kind demand parameter of first virtual machine It is matched respectively with the deployment conditions for the node for having first kind deployment conditions, determines multiple candidate nodes.

In implementation, the control node can be through but not limited to the mode of any one in following manner, described in acquisition The corresponding deployment conditions of multiple nodes of control node management：Mode one, multiple nodes week of the control node management Corresponding deployment conditions are reported to phase property the control node；Mode two, the control node is respectively to management Multiple nodes send the request for obtaining node deployment condition so that, will be respectively right after the multiple node receives the request The deployment conditions answered are sent to the control node.

Specifically, when the corresponding deployment conditions of the node that control node is managed are only capable of a need of matching virtual machine When seeking parameter, such as the corresponding deployment conditions of node that the demand parameter of virtual machine and control node are managed use label list When showing, for any one node in each node of the control node management, as shown in fig. 6, the control node can be with Judge whether any one described node is the candidate node that can create first virtual machine by following steps：

S601：Obtain a demand parameter of first virtual machine.

In implementation, the control node obtains different demands from a demand parameter of first virtual machine every time Parameter, to traverse all demand parameters of first virtual machine.It is described when first virtual machine has multiple demand parameters Multiple demand parameters of first virtual machine can be in the form of a list stored in the control node so that the control node When determining both candidate nodes in multiple nodes from management, obtained successively from the property demand parameter list of first virtual machine Each demand parameter.

S602：Judge whether otherwise the demand parameter for getting first virtual machine is held if so, executing step S603 Row step S607.

Specifically, if the demand parameter that the control node is got is sky, it is determined that the demand parameter not got, The i.e. last demand parameter got is the last one demand parameter of first virtual machine.

S603：Obtain the corresponding deployment conditions of any one described node.

In implementation, the control node obtains different deployment items from the deployment conditions of any one node every time Part, to traverse all deployment conditions of any one node.When any one described node has multiple deployment conditions, institute Stating multiple deployment conditions of any one node can in the form of a list be stored in the control node so that the control When node determines both candidate nodes in multiple nodes from management, from the deployment conditions list of any one node successively Obtain each deployment conditions.

S604：Judge whether the deployment conditions of any one node described in getting, if so, executing step S605, otherwise Execute step S608.

Specifically, if the deployment conditions that the control node is got are sky, it is determined that the deployment conditions not got, The i.e. last deployment conditions got are the last one deployment conditions of any one node.

S605：The demand parameter got is matched with the deployment conditions got, judges that the demand got is joined Whether number meets the deployment conditions got, if so, executing step S601, otherwise, executes step 606.

S606：Judge the deployment conditions got and be as first kind deployment conditions, if so, S608 is thened follow the steps, otherwise, Execute step S603；

S607：Judge not match with the demand parameter of the virtual machine in the corresponding deployment conditions of any one described node Deployment conditions in whether there is first kind deployment conditions, if so, executing step S608, otherwise, execute step S609.

S608：Determine that any one described node is not both candidate nodes, flow terminates.

S609：Determine that any one described node is both candidate nodes.

S503：First virtual machine creating request is transmitted to the first object node by the control node.

Accordingly, the first object node receives the first virtual machine creating request, according to first virtual machine The first kind demand parameter for the first virtual machine for including in request to create creates first virtual machine.

In one possible embodiment, the control node can also receive the second virtual machine of the second client transmission Request to create, wherein only include the second class demand parameter of the second virtual machine in the second virtual machine creating request；The control Node processed determines in multiple nodes of management according to the second class demand parameter of second virtual machine and creates second void Second destination node of quasi- machine, wherein the second class demand parameter of second virtual machine meets second destination node pair The second class deployment conditions some or all of are answered, and first kind deployment conditions are not present in second destination node；The control Second virtual machine creating request is transmitted to second destination node by node so that second destination node is according to institute It states the request of the second virtual machine creating and creates second virtual machine.It can be seen that in the embodiment of the present application, the control node institute Node with first kind deployment conditions in multiple nodes of management is only used for creating virtual with first kind demand parameter Machine, and the first kind demand parameter of virtual machine to be created all meets the corresponding first kind deployment conditions of node so that node On the specific resources resource of characterization (first kind deployment conditions) can be set type virtual machine it is exclusive.

Node due to that can create second virtual machine cannot have first kind deployment conditions, the control When node determines the second destination node for creating second virtual machine in multiple nodes of management, preferentially can never have Second destination node is determined in the node of first kind deployment conditions, so as to quickly determine second destination node, And then the establishment efficiency of the second virtual machine is improved, and the work that the control node determines second destination node can be reduced It measures.
