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.
