Plan machine etc., virtual machine creation system can be integrated on some main frame 2.Main frame 2 can be server or personal computer,
Or can be the computing device that other have computing capability.
Fig. 2 is a kind of flow chart of the virtual machine creation method according to an exemplary embodiment, the execution of the method
Main body is virtual machine creation system, and the method includes step as shown in Figure 2.
In step s101, receive the virtual machine creating request of tenant, the request of this virtual machine creating carries this tenant's mark
Know；
In embodiments of the present invention, when a certain tenant needs, when creating virtual machine, to send out to virtual machine creation system
Send virtual machine creating to ask, in the request of this virtual machine creating, at least carry the tenant identification of this tenant.
In embodiments of the present invention, this tenant may be for pre-set user it is also possible to not be pre-set user.Default tenant is permissible
Refer to the tenant having physical isolation demand to main frame.
Wherein, when a certain tenant is the tenant having physical isolation demand to main frame, this tenant often fortune to virtual machine
The requirement of row environment is higher, therefore needs an exclusive main frame when creating virtual machine, and uncommon with the virtual machine of other tenants
Enjoy a main frame.If that is, this tenant needs to create virtual machine on a main frame, now can not there are other in this main frame
The virtual machine of tenant, and after treating the virtual machine that this tenant creates this tenant in this main frame, can only continue to create in this main frame
Build the virtual machine of this tenant, and the virtual machine of other tenants cannot be created.
When this tenant is not the tenant having physical isolation demand to main frame, this tenant often running environment to virtual machine
Requirement relatively low；This tenant can not monopolize a main frame to create the virtual machine of this tenant, can be virtual with other tenants
A main frame shared by machine.If that is, this tenant needs to create on one host virtual machine, now there may be in this main frame
The virtual machine of other tenants；After treating the virtual machine that this tenant creates this tenant in this main frame, can also continue in this main frame
The continuous virtual machine creating other tenants.
Therefore, if this tenant needs to create virtual machine, virtual machine creation system is it needs to be determined that go out whether this tenant is right
Main frame has the tenant of physical isolation demand.So that virtual machine creation system is capable of determining that whether this tenant is that main frame is had
The tenant of physical isolation demand, before sending virtual machine creating request to virtual machine creation system, tenant needs this tenant
Add the tenant identification of this tenant, such virtual machine creation system just can be true according to tenant identification in virtual request to create message
Whether this tenant fixed is the tenant having physical isolation demand to main frame.
In an embodiment of the invention, originally each tenant is not the tenant having physical isolation demand to main frame,
Each tenant has tenant identification；Tenant identification is used for unique mark tenant, and such as tenant identification can be the name of this tenant
Claim or number.
For any one tenant, when this tenant needs an exclusive main frame to create virtual machine, this tenant is permissible
Monopolize the qualification of main frame to virtual machine creation system application, by afterwards, this tenant is has physical isolation to need to main frame for application
The tenant asking, virtual machine creation system will add default signature identification in the tenant identification of this tenant, for identifying this rent
Family is the tenant having physical isolation demand to main frame.
For example, it is assumed that each tenant identification is by 4 numeral compositions.Assume this tenant tenant identification be " 1234 " with
And default signature identification is " # ", then adds default signature identification " # " in tenant identification " 1234 " and obtain " 1234# ".
Therefore, virtual machine creation system may determine that whether carry default signature identification in this tenant identification；As this tenant
When carrying default signature identification in mark, determine that this tenant is the tenant having physical isolation demand to main frame, and then determine this rent
Family is default tenant；When not carrying default signature identification in this tenant identification, determine this tenant be not main frame is had physics every
From the tenant of demand, and then determine that this tenant is not default tenant.
In step s102, when this tenant is default tenant, true with the binding relationship of host identification according to tenant identification
The host identification of this tenant identification binding in the fixed request with this virtual machine creating, have with the request of this virtual machine creating in being somebody's turn to do
The main frame of this host identification of tenant identification binding is destination host；
Wherein, have the main frame of this host identification in this binding relationship only for create have with this binding relationship in should
The virtual machine of the tenant of tenant identification of host identification binding, the host identification that multiple main frames include having in this binding relationship
Main frame；In this binding relationship, each host identification uniquely corresponds to a tenant identification.
In embodiments of the present invention, may there are the simultaneously corresponding multiple different masters of tenant identification in this binding relationship
Machine identifies, for example, when tenant is to have the tenant of physical isolation demand to main frame and this tenant needs to create the number of virtual machine
When amount is very big, virtual machine creation system can distribute at least two main frames to from multiple main frames this tenant, and so, this binding is closed
The host identification of at least two and the binding of this tenant identification is there is in system.
Therefore, this step can be: if according to tenant identification and the binding relationship determination of host identification and this virtual machine
The host identification of this tenant identification binding in request to create is one, then this host identification is the main frame mark of destination host
Know；If this binding relationship according to tenant identification and host identification determine with the request of this virtual machine creating in this tenant identification
The host identification of binding is multiple, then select, from the multiple main frames mark determining, the master that any one host identification is destination host
Machine identifies.
In embodiments of the present invention, creating virtual machine in main frame needs to take the resource of main frame, for example, the calculating of main frame
Internet resources of resource, the storage resource of main frame and main frame etc., ability in the case that the remaining resource of main frame is enough
Virtual machine is created in main frame.For example, the memory space in each of virtual machine creation system main frame is all limited, with
And, the computing resource in each main frame is also limited.However, virtual machine creation system creates virtual machine in a main frame
When need take main frame in a part of memory space, and need take main frame a part of computing resource, the cpu of such as main frame
Computing resource and internal memory computing resource.
For any one host identification in this binding relationship, have in the main frame of this host identification and may also not create
Virtual machine it is also possible to create one or more virtual machines, for each host identification of other in this binding relationship,
Same.
Therefore, when needing to create virtual machine in the main frame have this host identification, need to meet a condition: have
Residual memory space in the main frame of this host identification is more than or equal to taking up room of virtual machine to be created, otherwise, in order to
Virtual machine to be created can be successfully created in the main frame have this host identification, then need to delete the master with this host identification
Other data of a part in machine, to create virtual machine to be created to reserve enough memory spaces, but so can lose
Lose this part of data.
Secondly it is assumed that the residual memory space having in the main frame of this host identification is more than or equal to virtual machine to be created
Take up room, but in the main frame have this host identification before founder's virtual machine, and be currently running virtual machine, due to
Main frame runs virtual machine to be needed to take the computing resource of main frame, and for example, cpu resource and memory source etc., when fortune in a main frame
When the virtual machine of row is more, then the occupancy of the computing resource of main frame is just higher.Because main frame is in the mistake of locally created virtual machine
Journey is also required to take the computing resource of main frame, therefore, when the cpu occupancy of a main frame or memory usage are too high, such as
Fruit also will create virtual machine in this main frame, then may affect the stability that main frame runs other virtual machines of establishment.
So, in order to avoid losing other data, and when avoiding creating virtual machine in main frame, impact has run other
The stability of the virtual machine creating, the request of this virtual machine creating also needs to carry resource requirement parameters, resource requirement parameters bag
Include the master of take up room, the create required occupancy resource of main frame taking of virtual machine and the required occupancy of virtual machine to be created
At least one of Internet resources of machine etc..
So, this step can be: if according to this binding relationship of tenant identification and host identification determine virtual with this
The host identification of this tenant identification binding in machine request to create is one, then this host identification is the main frame mark of destination host
Know；If this binding relationship according to tenant identification and host identification determine with the request of this virtual machine creating in this tenant identification
The host identification of binding is multiple, then select to meet this resource requirement in the multiple main frames that the multiple main frames with determination identify
The main frame of parameter is as destination host, and determines the host identification of this destination host.
Wherein, select to meet the main frame of this resource requirement parameters in the multiple main frames that the multiple main frames with determination identify
As destination host, comprising:
If the main frame meeting this resource requirement parameters in the multiple main frames that the multiple main frames with determination identify is one,
This main frame then meeting this resource requirement parameters is destination host；If the multiple main frames identifying in the multiple main frames with determination
The middle main frame meeting this resource requirement parameters is multiple, then select any one from the multiple main frames meeting this resource requirement parameters
Main frame determines one as destination host, or from the multiple main frames meeting this resource requirement parameters according to resource dispatching strategy
Main frame is as destination host.
For example, resource dispatching strategy can be load balancing etc..For example, in order to realize load balancing, work as residue
Memory space be more than or equal to virtual machine to be created take up room and remaining computing resource be more than create to be created virtual
When the main frame of the required computing resource taking of machine is multiple, virtual machine creation system can be, in these main frames, can select residue
The main frame that memory space is maximum and/or residue computing resource is maximum, and as destination host.
In step s103, asked according to this virtual machine creating, the virtual machine of this tenant is created on destination host；
In embodiments of the present invention, when technical staff sets up virtual machine creation system, arrange in virtual machine creation system
Multiple main frames, now multiple tenants can be respectively created the virtual machine of oneself in same main frame.
However, when a tenant is the tenant having physical isolation demand to main frame, this tenant is in virtual machine creation system
An exclusive main frame is needed to create virtual machine during middle establishment virtual machine, virtual machine creation system will be from virtual machine creation system
