Hi juzhang, According to wenli, there is no such issue with linux guest over rhel5.9 kvm, I will try this with kvm-83-256.el5 again, and update the result. thanks Best Regards, Dawn (In reply to comment #2) > can hit the same issue with linux guest?

Pls try to use e1000 to see whether hit this issue for the same windows guest 2. Pls try to use netkvm driver in virtio-win-1.0.3-1.52454.el5 to see whether can hit this issue . This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux.

Pls try to use netkvm driver in virtio-win-1.0.3-1.52454.el5 to see > whether can hit this issue . I have tried before and mentioned in bug description,this issue also happened on windows guest with netkvm driver in virtio-win-1.0.3-1.52454.el5 Thanks Best Regards, Dawn Postponed to RHEL5.10, as this is not a regression due to the use of 6.3 virtio-win (in RHEL5). Actually, it happens with E1000 too, so it is a host side problem. Please try to run the test with iperf in order to check if it is not netperf issue. Might be related also to bug#698541 - vhost-net/kvm need optimizations for UDP R from guest to host (In reply to comment #10) > Please try to run the test with iperf in order to check if it is not netperf > issue.
