How to discuss job search with your advisor when your career plans differ from what your advisor wants you to do?
I think a lot of how to approach it depends on the reason that your advisor things you should be heading for a traditional research career.  It's likely one of two things:


Your advisor thinks very highly of your work and doesn't want to "lose" you from the research community.
Your advisor is afraid that not placing students "highly" will reflect badly on their tenure case.


Neither of these is a good reason to choose a career path that you aren't interested in.  If it's the first, maybe you can get your advisor to listen by explaining that you really do want to embrace a teaching career.  If it's the second, then maybe you can explain that it will look a lot better on their tenure case to have an advisee placed at a well-respected teaching institution than dropping out of academia altogether.  At the end of the day, though, it's your choice and not your advisor's.

In either case, however, I would strongly recommend also seeking out other faculty members or external colleagues who understand you better. If you can find such other allies, they will be important in helping back you for the career that you want, whether or not your advisor comes around.
