Failed to open a session for the virtual machine

[LKnett]

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

3. Open an existing virtual machine. The problem happens immediately.

or

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

This was fixed in VBox 4.3.2.
