I got vhost_user_read() and vhost_user_write() backwards. But nevertheless they do the right thing. vhost_user_read() actually writes the message into socket, and vhost_user_write() reads it. So they should work correctly. I've just checked, fd number is not corrupted. Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia
