some more details (before I make a test case)

the glyphs of the real font have an expansion_factor of -10000 (post_linebreak) 
and the virtual fonts have an expansion_factor of 0 (so the question is: why).

The PDF also shows the expected differences:

(see the difference in the first argument to the Tm and the different kerning)

So I will investigate further where I messed up.
there is a test for the type being virtual .. can you omit that flag? just pretend it's a real font .. works here (i need to check why that test is there, it might not be needed in luatex any more)

so no type="virtual"
