It is worthwhile highlighting some of the advantages of using the VM over the
Live DVD.
1. The performance of the VM over the DVD is considerably faster;
2. The system configuration, preferences and datasets can be saved within the VM,
whereas they are lost once the live DVD is switched off;
3. Thirdly, the VM can be saved, backed up and re-utilized on different machines.
In order to run the VM, it is necessary to first install Oracle's Virtual Box
or VMWare. Virtual Box is available to download for free from the Virtual Box
website.

You should download the installation package for your host Operating Sys-
temand then follow the installation instructions from the installer. Once installed, you
should launch the program and you should see the Virtual Box interface (Fig.
B.1
).
You will subsequently need to download the OSGeo-Live VM, which is available
as a virtual disk file (vmdk) from the OSGeo website.

It is worth noting that it is
several GBs in size and you may therefore need some time to download it depending
on the speed of your Internet connection. Once downloaded, you need to unzip it to
obtain a vmdk file. Then click 'New' in the Virtual Box interface and add a name
such as 'OSGeo-Live' and specify the Operating System as Linux and Ubuntu as the
version.
You will then be prompted to specify the amount of memory (e.g. 1024 MB) and
then under the 'Virtual Hard Disk' you need to choose the option 'Use Existing Hard
Disk' and navigate to the location of the OSGeo vmdk file. You may need to modify
the Display settings under the 'General' tab of the VM Settings by increasing the
