Ok here is some  more information when I booted without the hypervisor
I was able to cleanly boot into the pv-ops Dom0 kernel.
i.e. with following grub entry
menuentry 'Ubuntu, with Linux 2.6.32.25' --class ubuntu --class
gnu-linux --class gnu --class os {
        recordfail
        insmod ext2
        set root='(hd0,1)'
        search --no-floppy --fs-uuid --set ef6fb0a3-17d8-46b8-944b-4d84fbd3c236
        linux   /boot/vmlinuz-2.6.32.25
root=UUID=ef6fb0a3-17d8-46b8-944b-4d84fbd3c236 ro   quiet splash
        initrd  /boot/initrd.img-2.6.32.25
}

but if I try to boot with hypervisor i.e. following grub


 menuentry 'Xen 4 Ubuntu 10.04 kernel 2.6.32.25 ' {
        insmod ext2
        set root='(hd0,1)'
        multiboot (hd0,1)/boot/xen.gz dummy=dummy
        module  /boot/vmlinuz-2.6.32.25 dummy=dummy noapt
 root=/dev/sda1 ro console=tty0
        module  /boot/initrd.img-2.6.32.25
 }

then I get some panic etc.

Linux ubuntu 2.6.32.25 #1 SMP Wed Mar 2 02:03:42 PST 2011 x86_64 GNU/Linux
