Cannot run Virtualbox in Custom Kernel
VirtualBox runs on the stock linux 2.6.25-2-xen-686.

However I have had to compile a custom kernel since I use the NVidia driver and this will not install on a Xen-enabled kernel.

Now I cannot run Virtual Box.


modprobe vboxdrv


FATAL: Module vboxdrv not found.
I have copied the /lib/modules/2.6.25-2-686/extra/ directory to /lib/modules/2.6.25/ (my custom kernel modules) but to no avail.

Can anybody help please?

You have to build the vboxdrv module against your new kernel source.
How did you install virtualbox? Can you do:
cd /usr/share/virtualbox/src/
sudo checkinstall -D make install
sudo modprobe vboxdrv

Edit: Another option is:
cd /usr/src/path-to-virtualbox-source
m-a prepare
m-a a-i virtualbox
m-a install virtualbox

Either way IMO it's better to use the binary virtualbox for lenny than apt-get the ose version which doesn't have usb support. With the binary version you build the module from /usr/share/virtualbox/src/.

Wow! That was an incredibly fast response!

I installed Virtualbox from the Debian Repositories.

The checkinstall -D make install failed with a strange message:


dpkg-deb - error: (upstream) version (`ose') doesn't contain any digits
dpkg-deb: 1 errors in control file

m-a a-i virtualbox failed too! The log file was empty.

# /etc/init.d/vboxdrv setup

Did you apt-get the virtualbox-ose-source package? I don't suppose debs work for self compiled kernels.

BTW, What does "uname -r" say? If 2.6.25-yourname or some such, recompile to 2.6.25-yourname1. Sometimes building debs against a kernel with no numbers in the revision (yourname) borks things up.

Kernel in SID is built using GCC 4.1. You need to install gcc-4.1 package before you try building virtualbox kernel module.

Run the following commands as root:


1. apt-get install gcc-4.1
2. apt-get install linux-headers-{$uname -r}
3. export CC=gcc-4.1
4. /etc/init.d/vboxdrv setup

Now include "vboxdrv" in /etc/modules otherwise you have to manually load virtualbox module with every restart.

No problem with the gcc-4.1 compiler. However I'm still tangede up and hope to be able to do some more work when I can get home at a reasonable hour.

I', having an error with VirtualBox, this happened suddenly, 1 day i ran it perfect, the other day didn't work, i think that was after a new kernel i installed (24.1), i got back the original kernel and nothing. I'm using a Lenny/Unstable system


debian:/usr/bin# uname -r

I reinstalled, using gcc 4.1 and the GCC default on lenny and nothing,


debian:/usr/bin# aptitude reinstall virtualbox
