Hi there,
I'm trying to boot Xen from grub2, and it's failing badly. This is the latest
grub2 tree (r2070). I'm using qemu to test. Here's the Xen boot log:

My grub2 stanza is
menuentry "Xen 3.3.1" {
set root=(hd0,1)
multiboot /boot/xen-3.gz com1=115200,8n1 console=com1,vga
module /boot/vmlinuz-2.6.18.8-xen root=/dev/hda1 ro xencons=ttyS0
console=tty0 console=ttyS0,115200n8
module /boot/initrd.img-2.6.18.8-xen
}
I built my grub with
./grub-mkrescue --pkglibdir=`pwd` --grub-mkimage=`pwd`/grub-mkimage
--image-type=cdrom --overlay=../grub2-memdisk/ ../qemu-image/grub-rescue.img
I start qemu like this:
qemu -m 1024 -serial stdio -L qemu-cbv2-grub2/ -hda
qemu-image/disk-i386-pristine.raw
And this is all i386, 32 bit.
Suggestions?
Thanks,
Ward.
