I already installed debian with hvm and the debian installer (no debootstrap).
During the installation it failed to install grub:
Searching for GRUB installation directory ... found: /boot/grubSo I mounted the image, I added "1:2345:respawn:/sbin/getty 38400
The file /boot/grub/stage1 not read correctly.
hvc0" to /etc/inittab and I booted using pv, pv-grub and xm console. I
tried to install grub using pv but I obtained the same error.
Yes, but I want the domU to automatically update menu.lst

Ahh, that makes sense.
How about this:
The latest kernel is always going to leave a symlink pair in root:
lrwxrwxrwx 1 root root 28 2010-06-27 09:29 vmlinuz -> boot/vmlinuz-2.6.34-5-server
lrwxrwxrwx 1 root root 31 2010-06-27 09:29 initrd.img -> boot/initrd.img-2.6.34-5-server
Have one manually constructed menu.lst that uses /vmlinuz and /initrd.img instead of the actual files in /boot/...
That lets the kernel version float under it and not have to keep updating the menu.lst.
It doesn't work if the grub package is not installed.

It should, but it doesn't succeed.

If debian cannot install the grub package the bootloader is useless

because I do not really need it, I just want the domU to update
menu.lst on its own.
