1. A method for recovering a virtual network, comprising:
- obtaining a snapshot of a virtual network, the virtual network including one or more virtual network devices, wherein a virtual network device is connected with at least one of another virtual network device and one or more virtual machines, and the virtual network is connected to a physical network through the one or more virtual network devices;
entering into a preset mode which prohibits a user from changing the one or more virtual network devices included in the virtual network;
in the preset mode, reading configuration information of the virtual network from the snapshot;
in the preset mode, based on the configuration information, creating one or more virtual network devices and distributing configuration parameters included in the configuration information to the one or more created virtual network devices;
disconnecting one or more target virtual network devices of the virtual network from the one or more virtual machines and the physical network, wherein the one or more target virtual network devices includes at least one of a virtual network device that needs an adjustment or a reset based on a user input, or a virtual network device that needs an adjustment or a reset according to a network error; and
based on the snapshot, connecting the one or more created virtual network devices to the one or more virtual machines and the physical network.

Abstract
The present invention provides a method and system for recovering a virtual network. The method may include obtaining a snapshot of the virtual network; and in a preset mode, reading configuration information of the virtual network from the snapshot. Further, based on the configuration information, one or more virtual network devices may be created and corresponding configuration parameters to the one or more created virtual network devices may be distributed. Based on the snapshot, the one or more created virtual network devices may be connected to virtual machines and a physical network.
