Assume that M is not a semi-bundle. We show that infinitely many fillings of M along dM are virtually Haken. It follows that infinitely many Dehn-surgeries of any non-trivial knot in the three-sphere are virtually Haken.This is the version published by Geometry & Topology on 29 November 2006Geometric Topology57M10, 57M25text
