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>
<h3>Updates</h3>
Put the server into Maintenance Mode. Download the updates suggested from the XenCenter on a client machine. Use SCP to copy the downloaded update file to a location you can find on the XenCenter server or on Windows use an SCP program like [http://www.putty.org/ Bitvise WinSSHD] . Then SSH from a client computer into the XenServer. Run For each of the following commands use the user 'root' and the password you setup during the installation of your XenServer. Start by running the following at the command prompt:

If everything looks good then run this command to restart server:
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 have your code and that you would likelet it reboot twice before initializing in browser).
One suggested change from the default Amahi install is to <b>make is the boot partition ext3Ext3</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 instructions.
<h3>Convert to PV or Paravitualize</h3>
You only need to do this for slightly better resource management, like attaching more than three VDI images. This is only possible if your boot partition is EXT3.

What you are looking for is the line that specifies your default linux boot option. Both the location and all of the kernel options. It might look like this:
<pre>
linux /boot/vmlinuz-3.10.5-201.fc19.x86_64 root=UUID=42e4c7e4-f260-4462-ad9c-c3f375e3a967 ro rd.md=0 rd.lvm=0 rd.dm=0 vconsole.keymap=us rd.luks=0 vconsole.font=latarcyrheb-sun16 rhgb quiet
</pre>
You also need the path for initrd. It might look like this:
<pre>
initrd /boot/initramfs-3.10.5-201.fc19.x86_64.img
</pre>
Then SSH in to the XenServer host and identify the name of the VM you wish to convert to PV mode.

<!--{{#tag:syntaxhighlight|{{{1}}}}}-->
You will need the name of the VM not the UUID. Now download the [https://www.cetic.be/IMG/zip/makepv.sh.zip makepv.sh] script.
