Absolutely correct.   You don't want to pick any profile with "xen" in 
the name for bare metal installs, you instead add the packages to your 
kickstart.   Of course when doing the guest OS's you do need the ones 
with "xen" in the name.

Ultimately having an "exclude-from-menu" feature in Cobbler (on the 
distro) might be worthwhile, as this can be detected during import.   
This would cause
any cobbler profiles attached to the distro to not show up in the menus 
because they weren't PXE compatible.   (Note that this will only ever apply
to Xen paravirt kernels).

Make sense?
