 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. I simply do not know what is wrong.

 Heh... 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.
