Na caixa Instalando Virtual no Ubuntu 14.04, recebi a seguinte mensagem:
Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a >permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
'/etc/init.d/vboxdrv setup'
as root. If it is available in your distribution, you should install the DKMS package >first. This package keeps track of Linux kernel changes and recompiles the vboxdrv >kernel module if necessary.

Eu entrei nestes comandos:
sudo apt-get install linux-headers-generic build-essential dkms
sudo apt-get remove --purge virtualbox-dkms
sudo apt-get install virtualbox-dkms
Em Execução do último comando
sudo apt-get install virtualbox-dkms
Eu recebo um erro:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
virtualbox-dkms : Depends: virtualbox (>= 4.3.10-dfsg-1)
E: Unable to correct problems, you have held broken packages.
Apenas para referência, eu verifiquei a versão da Virtual Box, eu tenho 4.3.16 r95972
Funcionou usando a solução
sudo apt-get install build-essential module-assistant
sudo m-a prepare
Segundo, como mencionado no erro, reinstale o módulo kernal.
sudo /etc/init.d/vboxdrv setup
