The kernel already has a lot of the Xen stuff enabled. AFAICT from
looking at the boot output it's just missing those two modules in the
initrd. (Although it's possible you'll need more.) I'm pretty sure
they should just come in the normal kernel rpm; there aren't really
any user-space components necessary for basic functionality of a Xen
guest. (There are a few tools which someone might want to install for
one purpose or another -- tools for querying Xen state or acting as a
"driver domain" -- but they're something that should be added as
needed, not in the core.)
I suspect we may need to run a dracut command in %post. Something
like:
dracut --add-drivers "some list of xen kmods ..."
I'm not sure which Xen drivers are required. The Fedora 21 kernel has
13 files named 'xen*.ko.xz'.
