I think you're missing my fundamental point. Don't use the kernel as the guest interface. Introduce a userspace daemon that exposes a domain socket. Then we can have a proper protocol that uses reverse fqdns for identification. We can do the backend over TCP/IP, usb, standard serial, etc. Regards, Anthony Liguori _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
