Sound nice because I already have a full virtualized Ubuntu on RHEL at the
moment. How did you switch to paravirt? Do you just install the Ubuntu Xen
kernel and reboot?

Allright, in a second time, I will check out the debootstrap method, I'm
already aware about it because I tried Xen on Ubuntu'Dom0 ;) I just have
to install debootstrap on RHEL : I will test this at the end of the week.
Thanks & Merry christmas to everybody ;)
