The method for rapidly expanding a virtual machine according to the embodiment of the present invention can implement rapid deployment of a virtual machine and reduce the workload of the operation and maintenance personnel. FIG. 1 is a schematic flowchart of a method for rapidly expanding a virtual machine according to an embodiment of the present application. The method includes steps S101 to S104.

S101: clone the virtual machine to obtain a virtual machine copy.

In the embodiment of the present application, in general, the cloning refers to copying the original state of the virtual machine in the VMware software, or performing a copy operation such as mirroring. The original state in the virtual machine includes each application in the virtual machine. The software, each script, and each application plug-in, etc., thus complete the operation of cloning the virtual machine, that is, completing the operation of cloning each application software, each script, and each application plug-in in the virtual machine.

It should be noted that cloning a virtual machine does not affect the virtual machine itself. That is to say, the virtual machine is cloned only for copying and mirroring, and the application software, scripts, etc. in the original virtual machine are not damaged. a software program, and the virtual machine obtained after the clone is called a virtual machine copy, the virtual machine copy can exist independently from the original virtual machine, the virtual machine copy has all the application software of the original virtual machine, all scripts, and all application plug-ins, etc. .

Further, as shown in FIG. 2, step S101 includes steps S201 to S205.

S202. If the operation of clicking the preset clone virtual button is detected on the preset clone platform, start the cloning of the virtual machine.

In the embodiment of the present application, the preset clone platform is VMware 8.0 virtual machine software, the virtual machine software integrates powerful desktop virtual computer software, and provides a user to run the virtual machine on a single desktop at the same time. Software, through the virtual machine software can also run different operating systems at the same time, as well as cloning, testing, development and other operations for different operating systems.

On the VMware 8.0 virtual machine software platform, there are preset clone virtual keys, such as menu VM, submenu Manage, and submenu Clone. When the user selects the virtual machine to be cloned as the target virtual machine, the hardware device Open the target virtual machine on the VMware 8.0 virtual machine software platform and start the cloning of the target virtual machine by clicking VM-Manage--Clone in the menu.

S203. Select a clone status of the target virtual machine in the current display interface.

In the embodiment of the present application, the cloning state refers to that the original virtual machine may be selected to be cloned as the current state of the parent, or the snapshot of the original virtual machine may be selected for cloning, and the cloned state may be in the click menu. After VM--Manage--Clone is selected, for example, if the virtual machine selected by the user is the original virtual machine, then the original virtual machine is selected as the parent to be cloned.
