XenServer: Install Zentyal on XenServer

Zentyal 4 is based on Ubuntu 14 but when I tried to install it on XenServer it wouldn't work so I went via an Ubuntu 14 install.

The process I followed was:

1. Install Ubuntu 14 (see other post)
1. Setup a new template for Ubuntu 14 
2. Install Ubuntu
2. Add the Zentyal repositories (see official guide):
1. sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
2. echo "deb http://archive.zentyal.org/zentyal 4.0 main" | sudo tee -a /etc/apt/sources.list
3. sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 10E239FF
4. wget -q http://keys.zentyal.org/zentyal-4.0-archive.asc -O- | sudo apt-key add -
5. sudo apt-get update
3. Install Zentyal:
1. sudo apt-get install zentyal
4. Connect to the Zentyal web interface and complete the installation wizard
