The kworker is handling the actual data moving in memory if I'm not
mistaking.
I think that is the vhost process itself. Maybe you mean the
guest thread versus the vhost thread then?
My understanding was that vhost writes data into a file descriptor which
then triggers eventfd.
That's at least how I read the vhost code if I remember correctly.
The handler beneath (the kworker) then runs the actual instructions that
move the data to the receiving vhost on the other end of the connection.
Again, I might be wrong here.
