I'm trying to get VirtualBox to work on ElementaryOS with kernel 3.2.0-49-generic. I've been getting this error :
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-ose-dkms package and the appropriate
headers, most likely linux-headers-generic.
You will not be able to start VMs until this problem is fixed.

Failed to open the X11 display!
I've searched and found that running :
sudo dpkg-reconfigure virtualbox-dkms
sudo dpkg-reconfigure virtualbox
Solves the problem.
But when i do sudo dpkg-reconfigure virtualbox-dkms. I get this error :
------------------------------
Deleting module version: 4.1.12
completely from the DKMS tree.
------------------------------
Done.
Loading new virtualbox-4.1.12 DKMS files...
Building only for 3.2.0-49-generic
Building initial module for 3.2.0-49-generic
ERROR (dkms apport): kernel package linux-headers-3.2.0-49-generic is not supported
Error! Bad return status for module build on kernel: 3.2.0-49-generic (x86_64)
Consult /var/lib/dkms/virtualbox/4.1.12/build/make.log for more information.
Now I've checked the make.log file i found this error :
DKMS make.log for virtualbox-4.1.12 for kernel 3.2.0-49-generic (x86_64)

make: Entering directory `/lib/modules/3.2.0-49-generic/build'
make: *** No targets specified and no makefile found. Stop.
make: Leaving directory `/lib/modules/3.2.0-49-generic/build
I have no idea what should be done from here. Any help will be appreciated.
if you do ls -l in /lib/modules/3.2.0-49-generic/ folder you will find that build is a symbolic link to the /usr/src/3.2.0-49-generic directory
ex:
sagar.sakre@sagar-vm /lib/modules/3.2.0-23-generic $ ls -l
total 4412
lrwxrwxrwx 1 root root 39 Aug 6 2012 build -> /usr/src/linux-headers-3.2.0-23-generic
So make sure that you have the built source code in /usr/src/ directory. If still problem persists upgrade the kernel.
