Karmic Koala no TTY

Hi,

I am having trouble using karmic koala x64 bit version of the image.
I can create DomU but when attached to console I can not see past "root filesystem mounted"

I had similar problems with other OSs but I could solve this by adding these to
.cfg file
extra = 'xencons=tty1 console=tty1'

But this does not seem to help with this image.

Here is my config file :
##############################################
kernel = '/boot/vmlinuz-2.6-xenU'
ramdisk = '/boot/initrd.img-2.6-xenU'
memory = 1024
name = "ubuntu.9-10.x86-64"
vif = [ '' ]
disk = ['file:/root/ubuntu.9-10.x86-64.img,sda1,w']
root= "/dev/sda1"
extra = "fastboot"
#extra = 'xencons=tty1 console=tty1'
##############################################

Many thanks
