I don't follow your logic from the commands you run earlier (did you
run fdisk? install debian domU first? chroot?). However it doesn't
really matter for PV domU. PV domU does not need grub to be installed
to MBR/partition for pygrub to work. It simply needs
/boot/grub/menu.lst (for grub) with the correct entries.
As for "automatically update the grub config (menu.lst) to boot the
latest kernel installed", you really only need these lines on
kernel-img.conf (on Ubuntu anyway. might be the same on debian) which
should exist already on a normal installation:
do_initrd = yes
postinst_hook = update-grub
postrm_hook = update-grub
Now, for HVM, it's slightly different. You REALLY need it installed to
/dev/sda. If you install Debian as HVM using the install CD, it
already does that automatically. If you want to install it manually
after that, you can:
- boot with a live CD (I like sysrescuecd)
- mount all the necessar partitions ( "/", /boot, and possible others)
- bind-mount /dev, /dev/pts/, /sys, and /proc to the mounted root
- chroot
- possibly edit /etc/mtab
- grub-install /dev/sda
