Hello, 


Try to specify no only kernel, but initrd (ramdisk) also.
You can do it with a line like this:

ramdisk="/ubuntu/initrd.img-xenpae"

(of course, you must specify correct name of ramdisk)


Also, make sure that you can mount /dev/system/ubuntu_lts
in the dom0 (to be sure, that you haven't damaged it during
transmition).


Regarding your question 
"""
Can I boot an install CD in /dev/dvd?
"""

yes, you can, but only if you have an HVM-capable system.
(if your system is not HVM capable you may also boot cd, 
and install system from it, but the CD must be modified to
be able to run in the PV mode. I suppose, that this is not 
a good option for you for this time.)
