I think what this is trying to get at is running Xen DomU's under KVM 
using Xenner, which is just another way to invoke KVM so it needs 
hardware virt assist.

Somebody might be upgrading a machine, and that machine may lack 
hardware virt assist because it's been a Xen Dom0 and Xen can do PV just 
fine without hardware assist.

So, if somebody upgrades to Fedora 12 from Fedora 8 they'll be SOL if 
they were running a Xen system, unless they have hw virt, in which case 
they'll be OK with KVM and Xenner (or if they install the experimental 
Dom0 support).
