How reproducible: Run a stress tests of a vhost-user interface using an UDP traffic generator. Traffic generator (IXIA) was connected to 2 physical ports that are in turn connected to 2 virtio ports through a linux bridge, VM (running linux) doing routing to forward packets between the 2 virtio ports. When traffic reaches high pps rates of small packets, Actual results: - VM stop transmitting packets Expected results: - VM should never stop transmitting packets Additional info: We do propose a fix at: http://lists.nongnu.org/archive/html/qemu-devel/2015-12/msg00652.html To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1556306/+subscriptions
