Once you have upgraded to version OS X 10.9 (13A603) Virtual Box does not work after the computer is turned off and displays the following error: "Failed to load VMMR0.r0 (VERR_SYMBOL_NOT_FOUND)".

To reproduce the problem do:

  1. Uninstall Virtual Box
  2. Install VirtualBox 4.3 and its respective extension
  1. Open an existing virtual machine. The problem happens immediately.


  1. Create a new virtual machine. Yes! you can!
  2. Turning off your notebook
  3. Connect the notebook, try to open the newly created machine. The problem happens immediately.
