Abstract : I will discuss the general form of supersymmetric backgrounds with two real supercharges of M-theory and type IIA supergravity (with non-zero Romans mass in general) on eight-dimensional manifolds with SU(4) structure. As a special case I will examine Calabi-Yau flux vacua and show that unbroken supersymmetry does not in general require the four-form flux to be (2,2) or primitive. In the case of M-theory large- volume Calabi-Yau flux vacua these results are in agreement with partial supersymmetry breaking in three-dimensional N=2 supergravity. Alternatively, the conditions for supersymmetry can be expressed in terms of a real 'superpotential' in accordance with three-dimensional N=1 supergravity. I will present explicit examples of M-theory flux vacua on K3 x K3.
