Just for my education and the rest of the list, what are you talking about?
What is a PV domain compared to a Windows guest? I use the GPLPV drivers
from James.

Federico, thanks for your support. But my patches are for PV-domains (or at
least for domains with PV-drivers) only. I think you are using Windows as
guest, so you would have to build a XEN-aware HAL...

If you are testing with PV-domains, too, you are welcome, of course!
