Hi All, The existing host networking API suffers from several deficiencies: 1. Part of it is a deprecated api designed for 3.0 clusters 2. SetupNetworks api introduced on 3.1 which is too complicated and verbose on the one hand, and incapable to natively support network topologies such as an isolated networks (network which isn't configured on any network interface). The complete list of deficiencies is listed on [1]. I'd like to propose an alternative API which addresses the existing issues and will allow us to support new networking features [1]. In addition, there are requests samples on [2] to demonstrate how the api should be called in order to achieve few of most commonly used network configurations. Please review and share your feedback.
