Android VM on Android

I want to run a android virtual machine on an android device, is there any method available for that?



-I am not asking to run android on Linux/PC/Mac but on Android.

-I know it'd be very heavy process to run this thing. Consider, I've a 4GB RAM device with Snapdragon's best available processor(take Octacore or something beyond).

-I want to do that for some fun, don't say "Why you need this?"

-It should be feasible on a non-root device. (preferable)

In short, Guest=Android, Host=Android



Thanks.
