It is found the most general local form of the 11-dimensional supergravitybackgrounds which, by reduction along one isometry, give rise to IIAsupergravity solutions with a RR field and a non trivial dilaton, and for whichthe condition $F^{(1,1)}=0$ holds. This condition is stronger than the usualcondition $F^{ab}J_{ab}=0$, required by supersymmetry. It is shown that theseD6 wrapped backgrounds arise from the direct sum of the flat Minkowski metricwith certain G2 holonomy metrics admitting an U(1) action, with a local formfound by Apostolov and Salamon. Indeed, the strong supersymmetry condition isequivalent to the statement that there is a new isometry on the G2 manifold,which commutes with the old one; therefore these metrics are inherently toric.An example that is asymptotically Calabi-Yau is presented. There are foundanother G2 metrics which give rise to half-flat SU(3) structures. All thisexamples possess an U(1)x U(1)x U(1) isometry subgroup. Supergravity solutionswithout fluxes corresponding to these G2 metrics are constructed. The presenceof a $T^3$ subgroup of isometries permits to apply the \gamma-deformationtechnique in order to generate new supergravity solutions with fluxes.Comment: 29 pages, no figures.
