Yes you are!
Your logs show:

I am confused that I don't see xenblk being loaded, yet you are
able to get mount the rootfs. Might be a NFS thing.
Try creating a special ramdisk/initrd for this machine on the
dom0 using:
mkinitrd /boot/initrd-2.6.18-1.2798.fc6xenU.img --preload=xenblk --with=xennet 2.6.18-1.2798.fc6xen
and change your config to use the ramdisk /boot/initrd-2.6.18-1.2798.fc6xenU.img instead.
Please let me know if this works.

Hi Paul,
It ends up in the same error with the following diff in the boot
sequence. I have also attached the complete boot sequence.

Also, for your reference, the config file for the VM is:
kernel = "/boot/vmlinuz-2.6.18-1.2798.fc6xen"
ramdisk = "/boot/initrd-2.6.18-1.2798.fc6xenU.img"
name = "grc59"
memory = "1024"
vif = [ 'mac=00:16:3e:0e:81:59' ]
root = '/dev/nfs'
nfs_server = '136.159.8.14'
nfs_root = '/home/xen-images/fc4'
Thanks for the help,
Abhishek.
