This tutorial will not include a detailed description of installing XenServer. That can be found on [http://www.xenserver.org/ XenServer.org].
Similar to other Virtualization tutorials, keep in mind that the install of XenServer will erase all data and drives connected to the local machine during the installation. The drives will become part of a an LVM group that XenServer will use for the creation of VDI all VDIs and guest VM containers. It is recommended that you disconnect all drives but one during this first setup. Later you can add drives and attempt more advance configurations, like greyhole for your Amahi VM. For now, this tutorial sets up a simple install of XenServer and one VM running Amahi 7.1
<h2>Download XenServer and the Management Console</h2>
Create a New VM, then choose <b>Other install Media Template</b>. Name the machine without spaces, choose to install from DVD drive where you have the Amahi 7.1 express disk located. Place on your XenServer and choose CPU and RAM. A recommended minimum would be 1 CPU, 2048 MB RAM. Now add a virtual disk. For better performance you should have a separate drive or drive pool for each VM you create. To start, create a 500 GB or larger VDI and move on to the network setup. Again, for better performance, choose a dedicated NIC for each VM. For this tutorial, you can just choose the defaults which is a shared NIC on your XenServer.
Switch to the console tab on the newly created VM and install Amahi 7.1 as per [http://docs.amahi.org/ instructions] (ensure you would likehave your code and that you let it reboot twice before initializing in browser).
One suggested change from the default Amahi install is to <b>make the boot partition Ext3</b>. While partitioning the hard drive, choose Ext3 rather than Ext4, because ’pygrub’, the XenServer bootloader for the PV mode, can’t read Ext4. If you wish to benefit from Ext4 advantages anyway, then you’ll have to you could create a /boot partition in Ext3 and the / partition in Ext4. Finish the Amahi install as per regular instructions. (ensure you have your code and that you let it reboot twice before initializing in browser).
If you are happy with a simple setup and not too concerned about performance then you could stop here and skip to the part about <b>installing Xen-Tools below</b>. The guest VM with Amahi installed on it is in <i>HVM mode or hardware assisted virtualization</i> (more information [http://en.wikipedia.org/wiki/Xen here]). If you would like your guest VM to run in <i>paravirtualization mode</i>, which will give better performance and access to more than three drives, you need to complete the next part.

Once you have the script downloaded and unpacked make it executable and run it.
<h3>Install XenServer Tools for linux</h3>
First Use XenCenter Management console to insert the <i>xs-tools.iso </i> in the DVD drive. Then SSH into the Amahi VM (<b>the console will tab may not work until these tools are installed</b>), and execute the following commands.
If you kept your guest VM in <b>HVM mode</b>:

If you converted your guest VM into <b>PV mode</b>;
