All I do is stress the network a bit by doing a ssh <physical-guest-NIC> cat /dev/zero > /dev/null on a second box. It usually takes 2-5 seconds until is stops working. It never took more than 30 seconds. IMO I did't do anything special in this setup. I can send you the kernel configs and a more detailed description of the setup if you like.
