Ok ok, i do not mind of course. :) Just i expected at least some, quick reply. It's like talking to a person while he/she suddenly starts ignoring you and turns away without any ACK/NAK.

Then i'm afraid the only option is the second one: GSI routing. It would allow to associate an irqfd with MSI bunch (data + address + devID) as it is. I'm also currently busy with some strange vhost-net performance issues, so i'll make another RFC later, after i redo my implementation using routing.
