I don't think so.  It's about 3 weeks since I installed FC7 (a fresh
install, not an upgrade), so I'm a little fuzzy, but I don't remember
asking for xen.  There's another odd thing about the setup, namely 
sysonfig/kernel is set not to use the latest kernel by default, which
answers my other question.

Vide:
        $ cat /etc/sysconfig/kernel
        # UPDATEDEFAULT specifies if new-kernel-pkg should make
        # new kernels the default
        UPDATEDEFAULT=no
        
        # DEFAULTKERNEL specifies the default kernel package type
        DEFAULTKERNEL=kernel-xen
        
I suspect this is the default or a very easy to get at option for the
installation of new kernels, which is why I put "HEADS UP!" in the
header.
