That isn't a standard xen line, it is a hack I put into the Fedora code to 
try to get xend to work better with selinux in recent Fedora versions (the 
switch to systemd might also have been a factor). You can probably safely 
throw away the xend.selinux.fixes.patch (or that part of it) for EL5 and 
EL6 as I think the selinux problems came later.
