integration unity3d and android x86

Sorry me for my bad English.
Android SDK very slowly works on my computer. And so I installed Android x86 2.3 (on Virtual Box), it works fast, but I do not know how to integrate with Android x86 2.3 Unity3d (that after the “Build and Run” opened Andoid x86 2.3 and run the application). Please help me solve this problem.

No way man, unity cant build apk for x86 android yet.
