Abstract

Systems and method for generating a network configuration model for a host computer system are disclosed. An example method may include querying a host computer system for network configuration data. The method further includes receiving, in response to the querying, the network configuration data including configuration data of network components included by the host computer system and configuration data of connectivity between the network components. At least one of the network components may be represented by a virtual network component. The method also, generates, in view of the network configuration data, a network configuration model.
