Setup Debian Lenny PV & HVM DomUs (64-bit) sharing same image device at Xen 3.4.1 & Libvirt 0.7.1-10 Dom0 on top of F12 (rawhide) with pvops enabled kernel.

Download mini installer iso image and virt-install Lenny HVM DomU:-

virt-install --debug -n Debian5HVM --hvm -r 1024 --vcpus=1 -f /dev/sda9 --vnc -c /home/boris/mini.iso

Login as root into HVM Debian DomU

# apt-get install linux-image-xen-amd64

Add entries to /boot/grub/menu.lst :-

title Debian GNU/Linux, kernel 2.6.26-2-amd64 (vfb)
root (hd0,0)
kernel /boot/vmlinuz-2.6.26-2-xen-amd64 root=/dev/xvda1 ro console=tty0
initrd /boot/initrd.img-2.6.26-2-xen-amd64
title Debian GNU/Linux, kernel 2.6.26-2-xen-amd64

kernel /boot/vmlinuz-2.6.26-2-xen-amd64 root=/dev/xvda1 ro console=hvc0
initrd /boot/initrd.img-2.6.26-2-xen-amd64

Modify /etc/inittab to support serial console ( just in case)
