I have faced with the same bug When a VM using virtio-net driver receives too much network traffic, the network interface stops working. Steps to reproduce -
On VM (with virtio-net): % nc -k -l 0.0.0.0 4242 > /dev/null On another machine (baremetal or VM): % cat /dev/zero | nc IP 4242 After some time, the VM network will stop working. With 2 listeners on the VM, I succeeded to reproduce this issue in about 1 hour. When I restart networking it working again I am using next packages: linux-image_3.2.0.23.25_amd64.deb qemu_1.0+noroms-0ubuntu13_amd64.deb -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997978 Title: KVM images lose connectivity with bridged network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bridge-utils/+bug/997978/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
