Get all required software over apt-get:

# apt-get install kernel-package ncurses-dev fakeroot wget bzip2 module-init-tools initrd-tools procps

Next, get latest linux kernel from kernel.org :

# cd /usr/src
# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.30.tar.bz2

you can also done it over apt-get as well:

# apt-get install linux-source

Extract it:

# tar -xjvf linux-2.6.30.tar.bz2

and make symbolic link pointed out your sources and go there:

# ln -s linux-2.6.30.tar.bz2 linux
# cd linux

Configure your new kernel with

make menuconfig

or

make oldconfig

or

# make xconfig

and so on.

After you will finished. Run :

# make-kpkg clean
# fakeroot make-kpkg --revision=kernel_name-version kernel_image

Where is kernel_name-version – kernel name and version(e.g.: custom-1.0).

If compilation done without errors. Go to the /usr/src and install new kernel over

dpkg

tool:

# cd /usr/src
# dpkg -i kernel-image-2.6.30.2_custom-1.0_i386.deb

Create ramdisk from new kernel :

# cd /boot/
# mkinitramfs -o /boot/initrd.img-2.6.30 2.6.30

Last one step is loader configuration. I will describe how to do this for two most popular(grub and lilo) loaders. If you have lilo loader just add new section into the /etc/lilo.conf and edit directive default. Like this:

default=MYKERN
image=/vmlinuz
        label=MYKERN
        read-only
        initrd=/boot/initrd.img-2.6.30

Now, install new loader at boot sector:

# lilo -c /etc/lilo.conf

In case of GRUB loader. Put next section into the /boot/grub/menu.lst file:

title           My Debian GNU/Linux, kernel 2.6.30
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.30 root=/dev/sda1 ro
initrd          /boot/initrd.img-2.6.30

For GRUB loader no installs is require.

After loader section done well you have to restart you machine:

# reboot

Check you current kernel version with uname if during your booting time no problems were occurred:

# uname -r
2.6.30

If it’s matched with you installed kernel version then you done everything right.

NOTICE: In my case distro is Debian.

My current kernel version is :

# uname -r
2.6.30-1-686

Let’s have a look about virtualbox module :

# apt-cache search virtualbox | grep [you_kernel_version]
# 

Nothing was found.

First of all we have to get kernel sources:

# apt-get install linux-source-[you_kernel_version]

Go to /usr/src and delete symbolic link linux if it exist:

# cd /usr/src
# rm linux 

extract files from archive and make new one linx:

# tar -xjvf linux-source-2.6.30.tar.bz2
# ln -s linux-source-2.6.30 linux

Now go to sources and set current configuration:

# cd linux
# make oldconfig && make prepare

After finished, run :

# /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel module:done..
Recompiling VirtualBox kernel module:done..
Starting VirtualBox kernel module:done..

Check is everything done right:

# lsmod | grep -i vbox

It’s okay if you get something like this:

vboxdrv                63936  0

Now you are ready to run VirtualBox.
