           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: Linux-2.6

Unable to create domU if I have modified config for network and IO tests.
I've seen the warning about the console . But the same problem occurred when I
set xen_cons = "ttyS0".

Will attach the .config file.
