What if i don't want KVM install no matter of hardware ?
I will want Xen on icore7 + ASUS P6TDT+ 16 GB RAM , Dell PowerEdge and so on ...

Fine. The point I was making is that a non-trivial user base has
hardware which does not support KVM, both legacy and recent low end CPUs
like ATOM (and Celeron, I believe). And there is a fair amount of old
hardware which does support KVM, but not all that well, like Q6600,
which benefit from using xen. So while KVM may be a choice for recent
hardware, there is a user base which would benefit from having xen.

And I would hope that the installer would be clever enough to see if KVM
is supported and offer xen if not. Doesn't need to be default, available
is fine.
