Side question, will you apply it to qemu-kvm from https://launchpad.net/~ubuntu-cloud-archive/+archive/ubuntu/mitaka-staging/+files/qemu-kvm_2.5+dfsg-5ubuntu5~cloud0_amd64.deb too? or should I open another bug? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1556306 Title: vhost-user: qemu stops processing packets under high load of traffic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1556306/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1556980] [NEW] vhost-user: qemu stops processing packets under high load of traffic
Public bug reported: Already described here, https://bugs.launchpad.net/qemu/+bug/1556306 Description of problem: - qemu socket becomes full, causing qemu to send incomplete SET_VRING_CALL messages to vhost-user backend (without proper fd set in ancillary data). - after some time, some interrupts are lost, causing the VM to stop transmitting packets. 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 for tracking, http://git.qemu.org/?p=qemu.git;a=patch;h=5669655aafdb88a8797c74a989dd0c0ebb1349fa ** Affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New ** Tags: 6wind ** Tags added: 6wind -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1556980 Title: vhost-user: qemu stops processing packets under high load of traffic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1556980/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
