I didn't manage to force the network to drop out by simply running iperf3. Had it running most of the day doing approx 2-3gbps traffic constantly.
The issue is still persisting though, so there must be something going on. I have now set some simple scripts which monitor packets per second and bytes per second logging them to a file and also something which monitors pings to both the local network and the wider internet. The ping monitor is set to log when network goes and restart the machine to get things back up and running. I am hoping that I'll find something in the logs at the times the network dies/the server restarts which will give an indication of what is going on. I will post another update when I have more info. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1694625 Title: KVM Guest loses network connectivity under heavy load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1694625/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
