Booting Xen dom0 with Grub2

Booting Xen dom0 with Grub2

[Emmanuel Jeanvoine]

Hi all,

I try to boot a Xen dom0 with grub2 on a Lenny box and it doesn't work.
After a few seconds of booting, the following message appears :
"Panic on CPU0:
 Cannot access memory beyond end of bootstrap direct-map area"

I tried with Grub-legacy and all works fine.

Here is the grub.cfg entry:
menuentry "Xen 3.2-1-i386 / Debian GNU/Linux, kernel 2.6.26-1-xen-686" {
	  set root=(hd0,1)
	  multiboot /boot/xen-3.2-1-i386.gz
	  module /boot/vmlinuz-2.6.26-1-686 root=/dev/hda1 ro
console=tty0
	   module /boot/initrd.img-2.6.26-1-686
}


Do you have an idea ?

Thanks,

Emmanuel Jeanvoine.

Hello. multiboot implementation of grub2 isn't complete yet. This is one 
possible reason. Can you supply us with the output of displaymem under 
grub1 and of lsmmap under grub2

Do you mean: at the bootime or once the system is booted ?
