We construct the supergravity solution in 11 dimensions describing D6-branes wrapped around a Kahler four-cycle with a B-fleld along the ∞at directions of the brane. The conflguration is dual to anN = 2 non-commutative gauge theory in 2+1 dimensions. We also construct the four associated independent Killing spinors. The phenomenon of supersymmetry without supersymmetry appears naturally when compactifying to type-IIA or 8d gauged supergravity. Therefore, this solution also provides an 11d background with four supercharges and four-form ∞ux, which is not obtainable from 8d gauged supergravity.
