Error: Error creating domain: (0, 'Error')

[System Administrator <sysadmin%punchyouremployer.com@localhost>]

Hi,
Im running NetBSD/Xen in Dom0 and Im trying to run Ubuntu in DomU. When I run 
xm create I get 

Error: Error creating domain: (0, 'Error')

my config file is:

kernel = "/var/images/xen/vmlinuz-2.6.16.13-xenU"
memory = 256
name = "ubuntu606-minimal"
vif = [ 'mac=00:16:00:00:00:06, bridge=bridge0' ]
disk = [ 'file:/dev/vnd0d,0x301,w' ]
root = "/dev/hda1 rw"

Does this look good to everyone else?

I used vnconfig vnd0 to map to the image to a device. The image is perfectly 
mountable.

xend.log shows me these errors.

Please someone help me. I dont know what to do anymore here. I need to get 
this virtual host up and running ASAP.

Thanks
