Yes, I do know you harish. We were neighbors in hostel as well :):).

comment zeros of $x^*Ax$, a quadratic form
You are right. It is far from stating the answer. I thought the reverse transformation is obvious. I have now explicitly stated it.

Your problem comes under the so-called quadratic programming with linear constraints. It is a well studied problem.
