Actually here are the major advantages of using the XEN virtualization
1. Optimized uptime
With the automatic migration feature of Xen, your website will never have to be affected by physical problems of the server machine. If the virtual machine that your server encounters problems, the entire server will automatically be migrated onto another machine, assuring optimized uptime and no downtimes
2. Superior flexibility
Machines running on Xen provide power and performance like no other. You have the freedom to adjust the power of your server without having to interrupt your services or move to another machine. If your site grows to a point that one virtual machine is not enough, you can expand to another, duplicate and configure your machine in just a few clicks. You can even add or remove shares as you deem necessary.
3. Your choice of system
Xen technology allows you the freedom of installing an operating system of your choice. You can also have access to install any software you need that runs on your OS of choice.
4. Excellent server and data security
For a virtualization system, Xen provides you with an unmatched level of security. There will never be intrusions of other servers installed on your physical machine so you can be confident that your server and you data are secure 24/7.
5. Cost-efficiency
Xen virtual technology allows all these aforementioned benefits at a fraction of the cost you would typically pay with dedicated web hosting.
