Virtual Box: VM won't start OS X Mavericks

Installed OS X Mavericks and VM Box now doesn’t work. I’ve been getting the following error, failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT).

Here’s how to solve.

1. Open Terminal

2. Type the following : sudo chown root /Applications

3. VM Should start.

This was happening to me on the latest version of Virtual Box and OS X was fully patched.
