It is shown that the Freund-Rubin vacuum configurations of d = 11 supergravity can be identified with corresponding vacua of non-chiral N = 2, d = 10 supergravity by considering the compact subspaces M 7 of the d = 11 theory as fibre bundles P(M 6,S 1) with the base spaces M 6, being the solutions of the N = 2, d = 10 equations of motion. But in spite of this correspondence between vacuum configurations of the two theories,in N = 2, d = 10 supergravity only backgrounds with M 6=T 6, SU(4)/U(3), K 3 × T 2, S p(2)/(S p(1)×U(1)), SU(3)/(U(1)×U′(1)) admit supersymmetry convervation in the effective d = 4 theory with only N = 8,6,4,1 supersymmetries being conserved.
