Hi Flavio, Thank you for reviewing the document! For some reason I thought we still need eventfd_link to notify the guests when new packets arrive. Indeed we don't need this anymore, I updated the wiki page. Regarding QEMU, can you please point me to the missing setup steps? (I think I already took care of them, anyway I want to be sure) Thanks, Marcel > > Thanks for doing that Marcel! > fbl >
