Either some output is missing, or something very strange is happening
in the appliance back end.  Would advise adding lots more debugging to
the code that starts at this comment:

  if (r == 0) {                 /* Child (qemu). */

I don't think the error has anything to do with qemu-nbd.  It doesn't
even get to the point where libguestfs prints the qemu command line.
