Xen crashes on boot

I've not been able to get Xen 4.1.2 to boot on Fedora 16. 64-bit kernel 3.1.2 boots on bare metal from Grub2 on a GPT-labeled disk, but Xen 4.1.2 crashes immediately after loading the initrd and reboots.

The reboot happens too quickly to see any screen error messages, but I wonder if I'm hitting this problem:

From what I can see, grub2 is a 32-bit package even on 64-bit, and the Xen hypervisor is also a 32-bit package even on 64-bit. It appears that grub2 is loading the dom0 kernel in an address the hypervisor can't reach, since I have 8GB RAM installed.

Insufficient information.

What kernel are you trying to boot ? Did you compile a kernel yourself ?

Rather then guessing at the problem, please post the relevant error message.

Can you check the logs then ? Shut it off when it reboots, boot a live CD, and check

/var/log/boot and /var/log/messages

Also check the kernel debugging page I gave you.

From "gzip -dc /boot/xen-4.1.2.gz | file - yields: ELF 32-bit LSB" and "I installed the x86_64 arch for xen-hypervisor" are you trying to boot a 32 bit kernel on an otherwise 64 bit OS ?

It appears that way.
