The following just showed up 3 guests > during initial boot (xendomains called on boot). Just to confirm, this was definitely during domain creation rather than restoring from a saved image? (which I think xendomains has an option to do) It might be interesting to print out requeue_idx in netfront.c just to check that it's not thinking it needs to do ring recovery.
