Consider that vacuum is made by virtual particles, and gravity its a space deformation. If we could build a "craft" that would interact with these virtual particles (maybe with space polarization with a very strong electric field), can we obtain a buoyancy effect on the "craft" from the sourounding space?

I really mean Levitation not "anti-gravity" based on space curvature or "gravity shielding" (these are practically impossible). I'm thinking at floating in a virtual particles ocean. Of course this depends of cosmological constant, which should be high enough for this effect.

Well there is the Casmir effect which is the attraction between two particles caused by the quantum vacuum, and the recent demonstration of repulsion based on the same effect. However, it is really a quantum effect and not likely to scale to macroscopic systems. And unfortunately, we haven't figured out how to make space-time have a positive curvature which would let you "levitate" in a gravitational field.

You are wandering into science fiction.
