Well, it can definitely be. In this specific case, I `yum upgrade'-ed
the system after a while and it installed both a new kernel and a new
Xen (along with a bunch of other stuff, of course).

Mmm... I see. Well, I think it's quite possible that a kernel and a xen
update happen at the same time, so this seems quite an issue to me... Am
I wrong?
What can we do to improve the situation? Should I open a bug against
grubby?
Thanks and Regards,

Happened again! Sorry I'm coming back to this thread so late, but I
couldn't access my Fedora test box for a while...
Ok, here's the thing. I booted the 'Fedora with Xen...' menu entry, so
I'm sure it was working.
I run `yum upgrade', and that involved installing a new version of the
Xen packages (at the end of the update, I have 4.2.1-7).
Now, here it is what I have in my /boot/grub2/grub.cfg:
menuentry 'Fedora, with Xen hypervisor' --class gnu-linux --class gnu --class
os --class xen $menuentry_id_option
'xen-gnulinux-simple-86a900c9-aa88-49f1-a007-0facdf17b732' {

}
Did you update the kernel at the same time? That looks like what you might
get with grubby which is run (which doesn't handle xen very well, which is
why xen-hypervisor runs grub2-mkconfig).

module /vmlinuz-3.7.6-201.fc18.x86_64 placeholder
root=/dev/mapper/host-fedora_root ro
}
OTOH, if I run `grub2-mkconfig | less', here's what I see:
menuentry 'Fedora, with Xen hypervisor' --class gnu-linux --class gnu --class
os --class xen $menuentry_id_option
'xen-gnulinux-simple-86a900c9-aa88-49f1-a007-0facdf17b732' {

--hint-efi=hd0,msdos8 --hint-baremetal=ahci0,msdos8
20f18f9a-c006-4d92-93d2-bf053c163638

search --no-floppy --fs-uuid --set=root

echo'Loading Xen xen ...'

echo'Loading Linux 3.7.6-201.fc18.x86_64 ...'

root=/dev/mapper/host-fedora_root ro
echo'Loading initial ramdisk ...'
module /initramfs-3.7.6-201.fc18.x86_64.img
}
So, again, since I was able to boot _before_ the upgrade, I'm sure the
initrd entry was there. Therefore, it seems the upgrade is re-running
grub2-mkconfig, but for some reason that does not result in adding the
initramfs module loading part. It looks weird to me that, running the
script by hand later, put it back there.
Michael, does running grub2-mkconfig from within the update do something
different than running it by hand?
If I can do any more digging that can help you investigate the issue,
please, tell me. :-)
Thanks and Regards,
Dario
