Perform.Also, although logical order is shown in flow charts, in some cases, can be with suitable different from herein
Sequence performs shown or described step.
Fig. 1 is the flow chart of the method for the internal memory of dilatation virtual machine provided by the invention.Method includes shown in Fig. 1：
Step 101, when creating virtual machine, in the memory configurations of the virtual machine set in exist perform dilatation operation
Maximum afterwards；
Specifically, when creating virtual machine, by the way that in configuration file required configuration can will be operated to internal memory dilatation
Parameter is completed to set, and is supported so as to provide configuration for follow-up dilatation operation, also ensures to perform dilatation on the premise of non-interrupting service
Operation；
Step 102, after the request of the dilatation to the virtual machine is received, obtain the mesh of the internal memory dilatation of the virtual machine
Mark size；
Specifically, after the request of the dilatation to the virtual machine is received, user can be asked to export the mesh of dilatation operation
Size is marked, target sizes of some reference informations needed for for user's selection can also be provided, such as according in nearest a period of time
The behaviour in service of memory source, the dilatation target sizes that may be needed most at present are calculated, so as to ensure that the target of user's request is big
Small technical ability meets the operation needs of virtual machine, also memory source will not be made to have excessive residue；Wherein, it is proposed that usage amount can be with
For a scope or several concrete numerical values；
Step 103, by the target sizes of the dilatation and it is described it is interior exist perform dilatation operation after maximum compared
Compared with；
After the target sizes of user's dilatation are got, to the target sizes of user's input, this can also be determined whether
The reasonability of target sizes；
If step 104, the target sizes of the dilatation are less than or equal to after the interior dilatation operation in the presence of execution most
Big value, dilatation is carried out to the internal memory of the virtual machine.
If specifically, the target sizes are reasonable, call the management tool of virtual machine that memory source is distributed into the void
Plan machine, so as to complete the dilatation of memory source.
Embodiment of the method provided by the invention, internal memory dilatation operation is completed most by being pre-set when creating virtual machine
Big value, provide configuration for subsequent thermal dilatation and support, after dilatation request is received, obtain the target sizes of dilatation operation requests,
By the way that target sizes compared with the maximum pre-set, to be determined to the reasonability of the target sizes, closed in target sizes
During reason, dilatation operation is carried out according to target sizes, on the premise of virtual machine is not interrupted, realizes the heat addition of memory source, it is real
The existing simple and convenient dilatation operation for more efficiently completing virutal machine memory.
