1. A method for dynamic configuration of a load balancer in a virtual network environment, the method comprising: configuring load balancing rules using virtual machine (VM) inventory objects, wherein the VM inventory objects are VMs and associated virtual network interface cards (vNICs), and wherein the VM inventory objects are specified in a source and/or a destination of the configured load balancing rules; transforming the configured load balancing rules by replacing the VM inventory objects that are specified in the source and/or destination of the configured load balancing rules with associated Internet protocol (IP) addresses using one of an IP address management (IPAM) table and a network address translation (NAT) table; sending the transformed load balancing rules to the load balancer for load balancing network traffic between a plurality of VMs running on at least one host computing system in at least one computing network; and dynamically updating the transformed load balancing rules sent to the load balancer when changes occur in the VM inventory objects.
