How to run Android ICS on a PC (win7) inside a VM? I have a PC and would like for kids to run Android games/edu apps. I have a touchscreen. How hard is it to run ICS inside a VM (VirtualBox or any other VM platform (MS, VMware)

There are answers about older versions of android. but I would like to run ICS.
Recent versions of the SDK include a native x86 Android image. (http://developer.android.com/tools/devices/emulator.html)
http://android-x86.org offers a 4.0 image that can be run from VirtualBox. 
http://androvm.org/blog/ offers a Jellybean (4.1) image for VirtualBox. 


Note that performance may not be so great.
