fontspec adds a number to the family name to be able to load the
same font with different features. So you would have to use eg
XITSMath(0). But looking at the fancyvrb code it is probably better
to define like for the predefined "tt" and "helvetica" a key word
which switch to the font:

\documentclass{article}
\usepackage{fancyvrb}
\usepackage{fontspec}

\newfontfamily \codefont{XITS Math}
\makeatletter
\@namedef{FV at fontfamily@code}{%
  \def\FV at FontScanPrep{}%
  \def\FV at FontFamily{\codefont}}
\makeatletter

\begin{document}
  \begin{Verbatim}[fontfamily=XITSMath(0)]
   abc
  \end{Verbatim}

  \begin{Verbatim}[fontfamily=code]
   abc
  \end{Verbatim}
\end{document}
