We need do "multilevel" boot on Dell poweredge server working in all 
cases, booting lvm volume and fallback.
With bios is impossible, bugs cause problem in some case.
With efi I not see bugs on boot cases but efibootmgr is not working with 
grub2 and xen.gz and we can't specify lvm for "static" boot order also 
with different disks.
xen.efi not compile when we build xen on Wheezy and probably is not 
possible boot with lvm volume, fallback options ecc...
UEFI with grub2 seem the best option but with xen hypervisor seem not 
load efi variable.
Thanks for any help and sorry for bad english
