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.
