Running VirtualBox VM host on ReadyNAS Pro

I upgraded again to 4.2.20 and still couldn't get it to work even after following the notes from itachi1, I guess I must have missed a step or did something wrong.
I think I did something wrong here:

Anyway, after that, I was able to run the VirtualBox installer 4.1.14 for amd64, then I started vboxdrv service to confirm: /etc/init.d/vboxdrv start Starting VirtualBox kernel modules ...done.

Anyway, moved back to 4.2.19 and re-installed virtualbox and it's working fine again, will try again this weekend.
