According to my limited knowledge, each PV driver consists of a backend
provided by Xen (e.g. netback) and a frontend running in the DomU (e.g.
netfront). The backend is responsible for the communication with the
hardware, e.g. via the network bridge. The frontend provides the device
which appears as a ordinary network device in the DomU. Both communicate
with each other to provide functionality. For more information, please
have a look at the available documentation, e.g. https://wiki.xenproject.org/wiki/Xen_Networking. > What about other Windows PV drivers defined in

Sorry, these questions go beyond my knowledge. I am not sure that what I
understand you want to achieve is possible with out-of-the-box Xen
resources. However, as already pointed out, the Xen wiki would probably
be a good first information source for you.
May I also kindly point you to the mailing list netiquette, where among
other things it is suggested to use bottom-posting? https://wiki.xenproject.org/wiki/Xen_Users_Netiquette > Am 04.01.2023 um 09:31 schrieb nihal dede bagci:
