How to migrate Xen from version 3.2 to version 4 on GNU/Debian Lenny

Xen is an opensource hypervisor. Version 4 has been released on the 7th of april 2010. Unfortunatly, Debian is only shipped with Xen version 3.2 for current stable Lenny, and version 3.4 for next stable Squeeze. Let’s see how to install Xen 4 on Lenny. More here

But we have to take care about some things in order to complete migration:

* We are about to upgrade Xen hypervisor. We will also have to upgrade Dom0 kernel (during my tests, Debian 2.6.26 kernel crashed while booting with Xen4 and I don’t have time to investigate it for now).
* Because we update Dom0 kernel, we must build a new DRBD module accordingly
* Finally, because we’ll build Xen from sources, we have to clean Debian install in order to avoid libraries conflicts.
