I don't have that either and what's more for me
`C-x v' is a prefix key.

But anyway, why do you want to kill buffers?
You don't have to kill the old buffers just
because you open a new file!

You can do something like this (the below code)
- however, I strongly disencourage from doing
this, because it'll explode in your face
like instantly!

Just to take one example, remember that Emacs
isn't just about editing files. It is also
about running programs, for example Gnus,
a shell, or actually just about anything.
Because opening/finding files is so common,
it (the keyboard shortcut) will enter your
muscle memory and you will unintentionally kill
all kinds of buffers before long.

Still,

    (defun find-file-kill-buffer (filename &optional wildcards)
      (interactive
       (find-file-read-args "Find file: "
                            (confirm-nonexistent-file-or-buffer)))
      (let ((buffer (current-buffer)))
        (when (find-file filename wildcards)
          (when buffer (kill-buffer buffer) ))))
