Hi, 
I tried some times again, and now i am running 7 machines concurrent.
during installation, the same error occured, but this was because i hadn't 
mounted the image-file partition at this time.
the only difference i can see is that i now didnt use the dom0_mem=64000 
parameter in the grub/menu.lst config.

perhaps it was this , I dont know.
if someone knows more about, please tell me

thank you for your fast help

stephan
