Surely there is no excuse for these scripts sending output to libxl's
caller's stdout.  stderr is another matter.

So I think libxl should redirect hotplug scripts's stdout to stderr.
If it had done this then Vasiliy would have seen the message on stderr
rather than it being mixed up with the migration stream.
