The embodiment of the present invention provides a method for configuring a virtual machine. As shown in FIG. 2, the execution entity of the embodiment is a virtual machine management module, and includes:

S201. The virtual machine management module creates a virtual machine.

Among them, a virtual network and a virtual network port are configured in the network management center. Specifically, the virtual machine management module receives the create virtual machine request message sent by the virtual machine management center, and selects a physical resource corresponding to the virtual machine according to the create virtual machine request message, and creates the virtual machine.

S202. The virtual machine management module sends a network configuration trigger message including the network connection information of the virtual machine to the virtual switch corresponding to the virtual machine, so that the virtual switch establishes the virtual switch and the virtual according to the network connection information of the virtual machine. Machine connection. The network configuration trigger message is used to perform network configuration for the virtual machine created by the virtual machine management module.
