How to run Android-x86 4.2 ISO on VM VirtualBox?

I asked same question in superuser and I found the way to start it. The correct answer is:

From the install/live CD, you just need to change the value of "androidboot.hardware" parameter in the grub command from "Android_x86" to "x86". You can do this by pressing "Tab" in the boot menu or by editing "isolinux.cfg" file on the installation ISO Image.

If you installed Android-x86 on hard drive,you have to select desired boot option and press e to edit grub command.

I don't know about the project Android X86 - Porting Android to X86. I see in the web, this emulator has a complex installation. I think, if you want to try a fast Android emulator and install easily, debug faster, you can try project AndroVM. It is easy to install it to Virtual Box by downloading the image file and import to Virtual Box .
