Hi, Daniele.
I like the main idea of this patch-set. I really thought to implement
something like this. Thanks for it.
I've done just a very quick look at patches. One comment posted to 11/11.
Main issue:
Patch set doesn't work for me.
I have a preconfigured database with n_rxq set for vhost-user ports.
But, after starting of vswitchd there is only one rx queue configured
per vhost-user port. And nothing changes after starting of VM.
So, VM started, ports configured, all vhost queues enabled, but only
1 queue really used by OVS.
Best regards, Ilya Maximets.
P.S. Some additional info:
