I have the same issue (overruns) and I have stalled network (in my other report I can only unstall the network by putting the NIC in promisc back and forth). The txqueuelen is indeed greater in the guest then the tap on the host, and I also notice that it's almost ways the output NIc which get stuck. So changing the tap (on the host) to 1500, I can't not reproduce the hang yet and a ping -f -s 64000 (between guests) does not produce any packet loss. 27810 packets transmitted, 27809 received, 0% packet loss, time 259080ms rtt min/avg/max/mdev = 5.013/7.639/33.999/1.536 ms, pipe 3, ipg/ewma 9.316/7.284 ms I hope this is the solution for my network stalls and packet loss in games. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
