Thanks Murali for your opinion. As I looked more in the code, managing host networks parts seems to be closely coupled to CitrixResourceBase and scattered inside the class. How about doing vif driver (NicTO handler ) first as a first incremental step and then clean up the networking parts to cleanly separate out from the resource? Thanks, Tomoe
