Before you go too far I suggest you talk to the Fedora maintainer(s) and the upstream maintainer(s) of grubby (who I think in this case are the same) because they are the ones that have to be convinced to accept the changes, and they may have ideas on the best way to do it. > How could we tie this into anaconda kernel upgrades?

That page https://fedoraproject.org/wiki/Features/XenPvopsDom0 isn't particularly up to date and the first stage may be to update it and then go through the process of getting it accepted as a feature, as other maintainers are more likely to be receptive to changes in that case. Currently that page mentions both /etc/sysconfig/kernel and /etc/sysconfig/xen . I would imagine that /etc/sysconfig/kernel is read already by new-kernel-pkg so it might be simpler to add a configuration option there.
