When booting the emulator from Eclipse, look at the Console tab, not the log tab. Console may show error messages. The Log tab only shows logcat, which are messages from Android itself

When you create a new emulator it warns you about assigning it too much RAM if you try anything above 768M the emulator may not start according to the error message at the bottom of the virtual device setup. Do try with 512M of RAM and see if it starts.

While creating emulator check the option "Use Host GPU" at the bottom

or try another API version
