sha512sum /mnt/tmp/boot/vmlinuz-3.11-2-amd64

I tried with ./grub-mkstandalone --grub-mkimage=./grub-mkimage -o 
pvgrub2.xen -O x86_64-xen -d grub-core/ /mnt/tmp/boot/vmlinuz-3.11-2-amd64
Probably I did something wrong or missed about this test.
On xl create it arrives to grub console, so I tried to set root and 
include the grub.cfg of domU but gave nothing, only new console line.
Can you give me more details to do a complete and correct test?

> Did you try root/linux/initrd/boot sequence manually?

I presume you mean to do insmod, set root and all other command manually 
without using grub.cfg, could you confirm that or give me an exact howto?
