I've developed on a VM in the past (VMWare), the experience was great - convenient to test on multiple platforms without rebooting etc. but it was difficult once I needed to do non-trivial graphics stuff with OpenGL - the performance difference was quite extreme. Hopefully this is something that will improve with future versions...

I've seen this too. OpenGL performance inside VMWare is much slower than native, and there are graphical artifacts in some cases (like lines across the diagonals of quads).

Some small details (like the apparent lack of line anti-aliasing inside VMWare OGL, and differences in the rendering of translucent polys) make me think it's partially or completely software emulated.

Yeah, if it the command buffer was being passed through to the hardware in exactly the same form then there shouldn't be these problems - I assume its something that is being done out of necessity for driver emulation.
