I'd worry about relying on Android-x86 at the moment as it's not an officially backed project from any OEM. However, Intel and Google have promised first-class support for x86 soon; so virtualized Android will likely be more trustable at that point.

FWIW, the Google TV (Android 3.1) SDK can run in KVM on Linux (current Google TV hardware is Atom-based); some of the work is already there.
