I didn't agree with TUV in dropping Xen - however I'm pretty sure it 
will return in EL7.

In modern distros - EL6 included - do not require any modifications to 
the guest kernel to utilise PV. This means you can just around run any 
current distro as a guest.

Yeah. You're probably right here - I do think that most people would 
never use an RCS system for grub.conf. Especially since each kernel 
install / upgrade edits this file automatically. The only real additions 
that we make is to add the lines I haven't figured out how to add 
automatically as yet.

I did look at this - however it seems that from all my experiments this 
is too much work to be feasible for just me to do at this point in time.
