dovrei installare un ambiente per creare un macchina virtuale ed avevo pensato a virtualbox.

La domanda è
cosa devo fare ? ci sono delle raccomandazioni ?

Via Gestore pacchetti non ho trovato un pacchetto virtualbox ma una sequela di pacchetti ...

grazie in anticipo !!

se ho capito dovrei fare se seguo https://www.virtualbox.org/wiki/Linux_Downloads

modifica per /apt/sources.list
ed inserire la mia ubuntu line che sarà avendo una 10.04

deb http://download.virtualbox.org/virtualbox/debian lucid contrib non-free

sudo apt-key add oracle_vbox.asc
oppure
wget -q http://download.virtualbox.org/virtualb ... e_vbox.asc -O- | sudo apt-key add -

adesso installo il virtual box

sudo apt-get update
sudo apt-get install virtualbox-4.1

per i moduli kernel host ...
sudo apt-get install dkms

ed infine
# sudo -s -H
# apt-get clean
# rm /var/lib/apt/lists/*
# rm /var/lib/apt/lists/partial/*
# apt-get clean
# apt-get update
questi comandi serviranno quando dovrò aggiornare i pacchetti dkms e virtualbox-4.1 ?

Riassumendo , no ho capito i comandi evidenziati in arancione. sono da dare oppure sono opzionali ...

The VirtualBox kernel module

VirtualBox uses a special kernel module called vboxdrv to perform physical memory allocation and to gain control of the processor for guest system execution. Without this kernel module, you can still use the VirtualBox manager to configure virtual machines, but they will not start. In addition, there are the network kernel modules vboxnetflt and vboxnetadp which are required for the more advanced networking features of VirtualBox.

The VirtualBox kernel module is automatically installed on your system when you install VirtualBox. To maintain it with future kernel updates, for those Linux distributions which provide it -- most current ones -- we recommend installing Dynamic Kernel Module Support (DKMS)[9]. This framework helps with building and upgrading kernel modules.

If DKMS is not already installed, execute one of the following:

   On an Ubuntu system:

   sudo apt-get install dkms

 
If DKMS is available and installed, the VirtualBox kernel module should always work automatically, and it will be automatically rebuilt if your host kernel is updated.

Otherwise, there are only two situations in which you will need to worry about the kernel module:

   The original installation fails. This probably means that your Linux system is not prepared for building external kernel modules.

   Most Linux distributions can be set up simply by installing the right packages - normally, these will be the GNU compiler (GCC), GNU Make (make) and packages containing header files for your kernel - and making sure that all system updates are installed and that the system is running the most up-to-date kernel included in the distribution. The version numbers of the header file packages must be the same as that of the kernel you are using.

       With Debian and Ubuntu releases, you must install the right version of the linux-headers and if it exists the linux-kbuild package. Current Ubuntu releases should have the right packages installed by default.

       In even older Debian and Ubuntu releases, you must install the right version of the kernel-headers package.

       On Fedora and Redhat systems, the package is kernel-devel.

       On SUSE and openSUSE Linux, you must install the right versions of the kernel-source and kernel-syms packages.

       If you have built your own kernel, you will need to make sure that you also installed all the required header and other files for building external modules to the right locations. The details of how to do this will depend on how you built your kernel, and if you are unsure you should consult the documentation which you followed to do so.

   The kernel of your Linux host was updated and DKMS is not installed. In that case, the kernel module will need to be reinstalled by executing (as root):

   /etc/init.d/vboxdrv setup
