At a certain point that I have not established exactly, the network load takes out the pv network. For example, if I initiate a bittorrent session in a pv domU, I get a slow build up of network load, and then connectivity is lost to both of the pv domU's. If I console into them, they cannot ping outside the network, but they can ping their own interfaces. A tcpdump on the dom0 physical shows no traffic. However, during all this, the hvm domains are able to use their network connections without issues.

I have experienced the same issue with Ubuntu 8.04. The only solution I have found is to limit the rate of the nic so that it doesn't reach a transfer rate that breaks the networking.
