Ah, ok. So I think we need to sort disks by bootIndex when passing them to xen
and increase bootIndex everytime we see bootable flag set when reading disks
back from xen. Of course, this will in fact change the order of disk elements
in the xml generated by libvirt vs. the xml passed by a user by the content
should not change at all. I think that should we fine.
