To use  Virtual Entity you need to have the following:

-terminal
-ssh
-python
-python-mysqldb

For *buntu or Debian users:
sudo apt-get install python-mysqldb
#if you use a local database
sudo apt-get install mysql-server apache2 phpmyadmin python-mysqldb

Mac Users:
It is always a good idea to have mac-port and fink installed. 
The Terminal is in /Applications/Utilities. 
Make sure ssh works and install python and python-mysqldb.

Winblows:
Sorry, there is no possibility, at this stage, to work on windows.
Please try a live CD.
