Oh i also noticed one thing.
Without mdadm installed in the client packages it won't mount 
dunno if that's a bug or not.

Error =

           Check root=bootarg cat /proc/cmdline
           or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/mapper/lvmtest-root does not exist. dropping to shell!

But it seems that the lvm setup turns things into some type of raid array?
I'm not installing a raid setup by the way i'm using the same lvm setup 
from configs in the previous messages in the thread

Hope this helps some debugging
