Hi,

Trying to run VirtualBox and getting this message

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (2.6.31.5-0.1-default) or it failed to
load. Please recompile the kernel module and install it by

sudo /etc/init.d/vboxdrv setup

You will not be able to start VMs until this problem is fixed.
WARNING: The compilation of the vboxdrv.ko kernel module failed during the
installation for some reason. Starting a VM will not be possible.
Please consult the User Manual for build instructions.

/usr/bin/VirtualBox: line 72: exec: /usr/lib/virtualbox/VirtualBox: cannot execute: Permission denied

So therefore as root running /etc/init.d/vboxdrv setup
