Yes they are similar things...
In the network case, we are adding a new driver that allows domains to access a new kind of network device. Currently, domains can only communicate to the world at large by using the rtls driver to access an emulated RealTek 8139. We are adding an xnf driver that will also allow domains to access an explicitly virtualized Xen network device. There is absolutely no connection or relationship between the RealTek devices configured into a domain and the Xen PV devices. Nils
