Installing 3.14.1 as per comment #17 fixed these connectivity issues for us as well, but it doesn't look like the 3.14.1 kernel made it anywhere near the 14.04.1 release. There is also no mention of this or any related bugs in https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes/ChangeSummary/14.04.1.
What else can we do except manually install 3.14.1, which is obviously not a proper solution? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325560 Title: kvm virtio netdevs lose network connectivity under "enough" load To manage notifications about this bug go to: https://bugs.launchpad.net/libvirt/+bug/1325560/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
