need another pv console connection for each console backend to export
the pty to dom0).

+The xenconsole program supports a very simple protocol to notify parent about
+its readiness. If xenconsole (the client) is exec'ed and has been given a fd
+(normally the write end of a pipe) via --start-noitify-fd option, it will
+write 0x00 to that fd after connecting to the guest but before entering the
+event loop. Parent can read fromt the read end of the fd to know the status.
