Xen 4.2 (current xen-unstable) supports EFI directly, so you can build xen.efi 
hypervisor binary 
which can be booted by UEFI firmware directly.

You also need to have UEFI patches in the dom0 kernel. Currently only Suse's 
xenlinux kernels
have xen dom0 UEFI patches included. The work is ongoing to get these patches 
ported to
upstream pvops dom0 kernels, and merged to upstream Linux.

Also there's the possibility of using grub2-efi to boot non-uefi-Xen, but you 
still need the dom0 kernel UEFI patches.
