First of all, thanks for your comments.
I understand that a chardev socket is either in client mode or in server
mode. If the 'server' parameter is not used, the socket is put in client
mode. At least this is the behavior when the socket is created by parsing
the command line. But, when created through QMP, without the 'server' parameter,
the socket is put in server mode.
Until this moment, I did not think that we can use "server=no" through QMP :))
So, yes. We may create the socket in client mode through QMP without this patch.
