I've run into one further problem here: It seems that the socket
attached to the pipe is already bound when the appliance comes up,
because I get an "Address already in use error" when I call bind(2) on
/dev/vport0p1 from the appliance side.
You're better off looking at the source and/or asking the qemu
developers. As you can see, we just open the device file. Whether
that is the correct thing to do is another matter:
http://git.annexia.org/?p=libguestfs.git;a=blob;f=daemon/guestfsd.c;h=eb1...
I'd been planing to listen on the appiance end of the pipe, and
have
clients connect from the host end. Is that not possible?
virtio-serial is like a serial port, and AFAIK there is no connection
control (or there didn't used to be). Anyway I strongly recommend you
ask the qemu developers or experiment yourself.
