XEN Hypervisor Project

For this extremely short tutorial, I suppose you are familiar with the HXen hypervisor and what you specifically want to do is turn one of your VMs or DomUs installation into a template you can use to install other VMs.

I needed to do exactly the same some days ago, but I was facing some issues, so I am basically writing this article to help out those who may be having similar issues.

Basically the workflow to go from a domU to a template is the following:

• Power off the domU
• Make the domU disk available to the host system as a folder (mount the domu disk into the dom0)
• Create a tar of the folder
• Then, use the tar file as the installation source of other domUs

1. Power off the domU
2. Make the domU disk available to the host system as a folder (mount the domu disk into the dom0)
3. Create a tar of the folder
4. Then, use the tar file as the installation source of other domUs
