There are lots of tutorials on the internet providing step by step guides for what you need. Asking LQ users to provide step by step guides will not get you any attention. LQ users are at there best when solving problems and are not very eager to do all the work for you. That means that you'll have to put in the work, show us what you have done and where you're encountering problems.
That being said, have a look at HowToForge.com
. They have a bunch of howto guides, almost copy paste. On the right top side of the main page there's a search box, type Xen in there and you'll see how many possible step by step guides you get.
