A virtual function is a member function which acts
on an object, and whose behaviour depends on the
dynamic type of this object.

A constructor makes an object from nothing. It doesn't
act on an object.

Strictly speaking, ``virtual constructor'' makes
absolutely no sens. (I think Stroustrup explains that.)
End of the story.

Since a ``virtual constructor'' cannot exist,
people can use this term to mean other things.
