27 Wow, it really does make a difference when we can see the configuration!

29 Actually you are not using savedefault like I was assuming. Which
30 basically means fallback only works when grub fails to load the kernel.
31
32 You said you followed the "HOWTO Xen and Gentoo" but looks like you
33 ignored section 6 on configuring the boot loader. It should look more
34 like this:
35
36 title Gentoo Linux 2.6.16-gentoo_xen_dom0
37 root (hd0,0)
38 kernel /boot/xen.gz dom0_mem=98M
39 module /boot/vmlinuz-2.6.20-gentoo-r8 ro root=/dev/sda2
40
41 Likely the dom0 kernel is failing because it expects to be run within
42 the hypervisor. You need to load that first as in the above.
43
44 Hope this helps.
