Yep, thanks.

Harmandeep is looking at (learning how to do) this already. If you feel
like sharing any knowledge/giving any advice on how to best achieve
that, I'm sure she'll appreciate (but if you can't or don't have time,
no problem :-D).

Right. Harmandeep, you can try this rather easily!.

You have a clone of the xen.git already. I think you just have to:
 - `make uninstall' (I'm not sure it will work, but it at least should 
    not harm!)
 - clean the sources
 - checkout, e.g., in a branch, one of the tags of a previous release, 
   say RELEASE-4.6.0 or RELEASE-4.5.0
 - build again
 - install
 - update the bootloader
 - reboot and report the result.

Regards,
Dario
