Virtualbox 4.1.18

1 Preliminary Note

I have tested this on an Ubuntu 12.04 server (host system) with the IP address 192.168.0.100 where I'm logged in as a normal user (user name administrator in this example) instead of as root.

2 Installing VirtualBox

To install VirtualBox 4.1 on our Ubuntu 12.04 server, we open /etc/apt/sources.list...

sudo vi /etc/apt/sources.list

... and add the following line to it:

[...] deb http://download.virtualbox.org/virtualbox/debian precise contrib

Then we download the VirtualBox public key...

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

... and update our package database:

sudo apt-get update

Afterwards, we install VirtualBox 4.1 as follows:

sudo apt-get install linux-headers-$(uname -r) build-essential virtualbox-4.1 dkms

(The dkms package ensures that the VirtualBox host kernel modules are properly updated if the Linux kernel version changes.)
Starting with version 4.0, VirtualBox has introduced so called "extension packs" and has outsourced some functionality like remote desktop connection support (VRDP) that was part of VirtualBox packages before version 4.0 into these extension packs. Because we need remote desktop connections to control our virtual machines, we need to install the appropriate extension pack now. Go to http://www.virtualbox.org/wiki/Downloads, and you will find a link to the following extension pack:

VirtualBox 4.1.18 Oracle VM VirtualBox Extension Pack
Support for USB 2.0 devices, VirtualBox RDP and PXE boot for Intel cards.

Download and install the extension pack as follows:

cd /tmp
wget http://download.virtualbox.org/virtualbox/4.1.18/Oracle_VM_VirtualBox_Extension_Pack-4.1.18-78361.vbox-extpack
sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.1.18-78361.vbox-extpack

(Make sure you grab the latest version from the VirtualBox web site.)
(Make sure you run the last command with sudo - sudo VBoxManage extpack install ... - because otherwise you will get an error like this:

administrator@server1:/tmp$ VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.1.18-78361.vbox-extpack
0%...
Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to install "/tmp/Oracle_VM_VirtualBox_Extension_Pack-4.1.18-78361.vbox-extpack": The installer failed with exit code 127: Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address
administrator@server1:/tmp$

)
Now we must add the user that will run VirtualBox (administrator in this example) to the vboxusers group:

sudo adduser administrator vboxusers

VirtualBox is now installed and ready to be used.

For Debian it is available in Lenny backports and in the normal repository for Squeeze and later. The dkms package can be installed through the Synaptic Package manager or through the following command: sudo apt-get install dkms
