} The disk parameter looks like this:

     Reading the Xen logs on the dom0 would have given you a strong
hint.  Anyways, the Xen stuff doesn't seem to like symbolic links, so
you need to give the physical paths, i.e.:

disk = [ 'phy:/dev/mapper/vg0-domu--ns1,0x1,w' ]
#disk = [ 'phy:/dev/mapper/vg0-domu--ns1,0x1,w', 
'file:/usr/local/isos/NetBSD-5.1,0x2,r' ]

} I also noticed that the logical volume cannot be vnconfig'd:
}    # vnconfig vnd0 /dev/vg0/lv0
}    vnconfig: /dev/rvnd0d: VNDIOCSET: Operation not supported

     You can't do that.  vnd is for files, not devices.
