Hello,

With the help of Nikita, I've figured out how to get rid of
"xvda: unknown partition table"

I have to use /dev/xvda1 not the /dev/xvda

-------------------------------------
disk   = ['phy:/dev/vg01/vm0,xvda,w']
root   = '/dev/xvda ro'
-------------------------------------

changed to:

-------------------------------------
disk   = ['phy:/dev/vg01/vm0,xvda1,w']
root   = '/dev/xvda1 ro'
-------------------------------------

Anyway booting freezes. Once I've saw:

-------------------------------------

So I guess may be it's related to some DomU kernel configuration
problem? I've attached it to this letter.
