Virtual machines are not currently well-supported by our 3D tools.  There
have been reports of success using them but you need to set up your VM to
support hardware acceleration.

Other than nav_view it sounds like everything's working fine.  Closing stage
does not kill the rest of the roslaunch, which includes a number of other
processes that rely on the fact that stage is running -- hence the warnings
once it is closed.
