Webdevelopment on an usb-stick
In the following howto I'll explain how to install the virtualbox and use the live-usb-installation for webdevelopment.
The beauty of a virtual machine is that you can mess with servers and websites without having all in "production".
In this howto I will cover the setup of virtualbox on the xubuntu-live-usb installation as described here .... so you could test any server setup or use the howto for the dedicated drupal server or the Vmware ubuntu server tiddlyweb installation
First we do a system update and after that make the wireless work.
(on the Acer we load the available wifi driver)

Now we can start preparing the system for webdevelopment.
Install Virtualbox and Gftp (see pics).
Select Synaptic Package Manager.

Install Gftp.

Install Virtualbox.

When finished start virtualbox and follow the installation setup.....
I used the defaults for most (you need bridged network).

Create a virtual disk with 1gb size (ubuntu server installation with drupal is about 700mb.....so leaves a 300mb webspace....enough to test modules...do theming etc.).

Now you can test and run any server-setup or check the howto for the dedicated drupal server
Enjoy!
