Unfortunately it looks like more and more people are of the opinion that
grub2 is useful even on UEFI firmware.
For example, it is pretty clear that Ubuntu is still going to boot Xen
via grub2 no matter how the firmware looks like.


What would it take to make Xen work properly with grub2 on a UEFI firmware?
I think that we should add it as a work item for Xen 4.3.
