So you've booted into XenLinux and you're creating another domain?  How did 
you build the filesystem for this domain?

In any case, domUs will not see the real physical hardware because they only 
have virtual devices.  I guess the filesystem for this domain was originally 
installed onto the bare hardware, right? (e.g. using the install CD).  Kudzu 
is just noticing that the devices it had when it was installed are now not 
present.

You can tell Kudzu to just ignore the changes or to deconfigure the devices 
(if you only intend on running this in a domU and never booting it directly).  
You could also disable Kudzu.

HTH,
Mark
