As a temporary workaround, I've prepared a QEMU 2.5 with a higher virtio RX/TX queue size - just like the change that mitigates the issue:
https://launchpad.net/~inaddy/+archive/ubuntu/lp1668829work That contains the workaround (256 -> 1024 change on virtio queue size). The QEMU pkg version is: 1:2.5+dfsg-5ubuntu10.9~cloud1~lp1668829~work1 I'll use another PPA for possible tests. This one will have the workaround only. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668829 Title: Performance regression from qemu 2.3 to 2.5 for vhost-user with ovs + dpdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1668829/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
