There are some other problems with usb too: It's not transparent to users. Any hotplug event could alert users and that's not desired. It's a system-only thing and should also remain that way.I think virtio-serial is the better way to handle vmchannel. Unlike usb virtio is designed to work nicely in a virtual environment.But vmchannel-over-usbserial should be easy too though in case some guests lacks virtio backports or something.
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
