I suppose you intend to force XeLaTeX usage.

This doesn't work because xelatex produces pdf file, not dvi file.
Comment out those two customizations and try the following (after you
restart the emacs session).
(1) After you open your XeLaTeX document, open the menu
    "Command"->"TeXing Options" and select "Use XeTeX engine"
(2) Type C-c C-c (for ordinary typeset) or C-c C-p C-d (for preview-latex).

If it does the trick, Change the default value of `TeX-engine' from
`default' to `xetex' via
M-x customize-option RET TeX-engine RET
. Then the customization will persist across emacs sessions.

AUCTeX doesn't have these four options. Why do you have them? Perhaps
some other package(s) offer them?
