Android emulator doesn't start anymore

Question

I'm running on OSX Mountain Lion. I recently installed the latest version of Eclipse and the Android SDK from Eclipse. I updated the SDK through Eclipse as well, downloading everything in the Extras, Android 2.2 (API 8), Android 4.1.2 (API 16) and the Tools folder.

Finally I could run the emulator by creating a device but it was very slow (I have 250gb ssd hard drive + 16gb RAM), I couldn't even run the application I had. I tried to modify some options of the emulator and now apparently I can't run anything anymore. As soon as I try to run a program (Hello World) I get the following infamous Mac OSX error:

emulator-arm quit unexpectedly.

The console output for Eclipse is the following:

[2012-10-19 15:46:06 - test] Android Launch!
[2012-10-19 15:46:06 - test] adb is running normally.
[2012-10-19 15:46:06 - test] Performing com.example.test.MainActivity activity launch
[2012-10-19 15:46:06 - test] Automatic Target Mode: launching new emulator with compatible AVD 'test'
[2012-10-19 15:46:06 - test] Launching a new emulator with Virtual Device 'test'

I tried to reset things as they were before as well as creating a new emulator device. I tried to restart Eclipse and the machine itself but nothing. Apparently I can't run any Android application anymore.

Does somebody has some idea? I read on some similar thread to use adb to restart the thing, but apparently I can't get that running as well. By doing ./adb shell I get error: device not found. Do you have any idea about what can I do to solve the issue?

Thanks

FWIW I noticed that running VirtualBox seems to get a lock on HAX which prevents android emulator window from ever opening. Closing VirtualBox seems to release the lock and everything works again.
