Hi stefano,

   It's very great of your work.I think it't useful 
to me, I have checked it out, and I will study it.
  What I care mostly is the pv-on-hvm drivers, now 
my main work is port pvonhvm drivers to various guest
OS, no matter what OS version, such as ubuntu 10.10, 
debian 505 etc. But I found this work is difficult & 
boring to me, I can't find a general method which can 
easily port the pvonhvm drivers to all kinds guest os.
Do you have any good ideas?
   I found there are not platform-pci source in your 
project, as we know, in the old pvonhvm drivers version,
platform-pci module is important, it was used to establish
the communication mechanism, such as xenbus, evtchn,etc, 
could you please tell me how can you get rid of it? and how 
can you substitute platform-pci, with which?
    Thanks a lot.
