Well, it depends on if you are talking about the non-upstream Xen patch, or the current upstream pv_ops. The former is all but dead, so you don't have to worry about that, and the latter *should* (famous last words) mostly stay out of your way through pv_ops. Though I haven't gone in and implemented it myself, so it's easy for me to say :). I think choosing PAE at runtime would be the ideal situation, if we can get there. -- Chris Lalancette _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
