In Linux at least a VLAN does look like a NIC (interface) on the TS. You first configure the interface, then to use a VLAN, you end up creating a virtual interface (for that VLAN) that connects through the other interface. To the linux host, each VLAN appears as its own interface. See the "vconfig" command for instance on how this works. But in any case, I think the broader point stands that a TSI is the hypervisor-facing side, whereas on the TS, you get an interface of some sort. The exact details of how that interface is presented depend on the TS (whether linux, microsoft, etc.) itself. But that is the case whether the interface is physical or virtual.
