The method provided in an embodiment of the present invention for determining resources of virtual machine, as shown in Fig. 2 can apply to NFV frameworks as shown in Figure 1, comprises the following steps：
201st, VNFM determines the parameter for the resource that VNFD is indicated；
The parameter for the resource that VNFD is indicated, can be adjusted setting, for example, the parameter of the resource of VNFD instructions can be set according to the parameter of Host resource.Specific implementation is as follows：
After Host starts, the parameter of Host resource is stored in VIM, and VNFM can obtain the parameter of the resource of the Host in VIM by Vi-Vnfm interfaces, for example, can have following two ways：
1, periodically verify
VNFM periodically (such as with one minute frequency once) sends inquiry request to VIM, and the parameter of Host resource is issued VNFM, for example, the parameter of the Host inquired resource can be sent to VNFM by Vi-Vnfm interfaces with VIM by VIM.
2, triggering is reported
When increasing or deleting Host, the parameter of Host resource can be issued VNFM by VIM with the Vi-Vnfm interfaces between reverse calling and VNFM.
The parameter of Host resource in the present embodiment, VNFD indicate resource parameter, and VM resource parameter in parameter represent by taking most common three kinds of resource dimensions as an example to illustrate in resource dimension, the embodiment of the present invention, as shown in figure 3, i.e. CPU frequency, memory size and memory space.It is understood that above-mentioned three kinds of dimensions are a kind of exemplary sample, one or more of which can be selected, other resource dimensions can also be selected, do not limited herein.
For example when the parameter of the Host of acquisition resource is：
CPU:16 × 2.2G Hz, internal memory：64GB, storage：16T
According to the parameter of above-mentioned Host resource, the parameter mode for building the resource that VNFD is indicated is as follows：
According to Host CPU frequency, memory size and memory space, equal proportion builds the parameter for the resource that VNFD is indicated, the parameter for the resource that can for example indicate VNFD is configured to following specification：
CPU:1 × 2.2G Hz, internal memory：4GB, storage：1T,
Other specifications can certainly be configured to, for example：
CPU:2 × 2.2G Hz, internal memory：8GB, storage：2T, the parameter for the resource that the VNFD specifically built is indicated, in addition it is also necessary to meet the resource needed for operation business function, it can be understood as meet minimum CPU frequency, memory size and the memory space required for a certain business function；
For example run a call business, it is necessary to least resource be：
CPU:1.4 × 2.2G Hz, internal memory：3GB, storage：0.7T, so in order to meet run the paging service required for resource, the parameter for the resource that the VNFD of structure is indicated should be more than or equal to the resource run required for the paging service, i.e. each resource dimension is required for being more than the resource required for operation GIA call business, at this point it is possible to which the parameter specification of the VNFD resources indicated is configured to：
CPU:2 × 2.2G Hz, internal memory：8GB, storage：2T.
202nd, VNFM determines the parameter of virtual machine VM resource according to the parameter of the VNFD resources indicated, and the parameter for the resource that the parameter of the resource of the VM and the VNFD are indicated is proportional.
After the resource parameters of VNFD instructions are determined, for example, when the parameter of the VNFD resources indicated is defined as：
CPU:2 × 2.2G Hz, internal memory：8GB, storage：2T；
VM specification is so built according to equal proportion；
Meanwhile, in order to ensure VM disclosure satisfy that operation business function needed for least resource, it is necessary to so that identified VM specifications be equal to or more than operation subservice function needed for resource.
It is some subservices by the overall service decomposition for example, running certain call business, some minimum subservice of resource is as reference needed for choosing, and such as resource needed for the subservice is：
CPU 0.5 × 2.2G Hz, internal memory 1.5G Hz, store 0.4T
VM can be then configured to：
CPU 0.5 × 2.2G Hz, internal memory 2G Hz, store 0.5T
Enable the resource such as VM CPU frequency, memory size and memory space built to cover the least resource needed for the minimum subservice function of operation, and with the parameter of the VNFD resources indicated It is proportional.

The parameter of VM resource is built according to the ratio of the parameter of Host resource so that the parameter of the resource of the VM is proportional to the parameter of the resource of the Host；
For example, when the parameter of the Host of acquisition resource is：
CPU:16 × 2.2G Hz, internal memory：64GB, storage：16T,
So can be with scaled down VM specification, therefore the parameter of VM resource can be configured to following specification：
CPU 0.5 × 2.2G Hz, internal memory 2G Hz, store 0.5T.
Optionally, in the present embodiment, the ratio of the parameter for the resource that can also be indicated according to VNFD builds the parameter of VM resource so that the parameter of the resource of the VM is proportional to the resource parameters of the VNDF.
For example, when the parameter of the VNFD of the factory default resources indicated is：
CPU:3 × 2.2G Hz, internal memory：12GB, storage：12T.
So the parameter of VM resource for example can be configured to by following specification with the parameter of scaled down VM resource：
CPU 0.5 × 2.2G Hz, internal memory 2G Hz, store 2T.
In order to ensure that VM can run subservice function, it is necessary to which so that the parameter of the VM determined resource is equal to or more than the resource needed for operation subservice function；
It is some subservices by the overall service decomposition for example, running certain call business, some minimum subservice of resource is as reference needed for choosing, and such as resource needed for the subservice is：
CPU 0.5 × 2.2G Hz, internal memory 1.5G Hz, store 0.4T
VM can be then configured to：
0.5 × 2.2G of CPU Hz, internal memory 1.5G Hz, store 0.4T, it is appreciated that, the VM also can be configured such that other specifications, as long as meeting the resource that its specification is more than or equal to needed for operation business function in theory so that the resource such as the VM of structure CPU frequency, memory size and memory space can cover the least resource needed for the minimum subservice function of operation.
A kind of method for determining resources of virtual machine provided in an embodiment of the present invention, VM parameters are built by the parameter of the parameter of the resource indicated according to VNFD or Host resource, so that the parameter of VM resource and the VNFD resources indicated parameter or Host resource parameter it is proportional, and then the parameter specification of VM resource is rebuild, it can largely reduce the resource fragmentation in Host；Further, because the VM built as described above can be significantly reduced fragment, Host resources are made full use of, when needing increase service operation resource, the fragment resource in Host can be preferentially utilized, so as to reduce the other Host chances of increase, the VM specifications built compared to prior art, when The fragment resource in Host can not be utilized during operation business, new Host can only be increased to meet business demand, and then increase the communication flows between different Host.

In triggering is reported, when increasing or deleting Host, VIM can be with reverse calling and the device Between Vi-Vnfm interfaces, the parameter of Host resource is issued into the device.
For example when the parameter of the Host of acquisition resource is：
CPU:16 × 2.2G Hz, internal memory：64GB, storage：16T
According to the parameter of above-mentioned Host resource, the mode that the first construction unit 501 builds the parameter for the resource that VNFD is indicated is as follows：
According to Host CPU frequency, memory size and memory space, equal proportion builds VNFD resource parameters, for example, VNFD resource parameters can be configured into following specification：
