So I'm sorry to report that after about 50 days of uptime on qemu-kvm (1.0+noroms-0ubuntu14.3) I had 3 VMs out of ~60 in my cluster drop off the network. It happened on different host machines, so it's not a single machine in the cluster that's a problem.
Two of the nodes were restarted (full qemu shutdown/relaunch) so I didn't have a chance to debug them. One of them I was able to console and work on before I gave up and restarted it. The interesting things I discovered was that the workarounds I had done in the past did not work. Previously I was able to ifdown/ifup the virtual interface to restore networking. Also migrating between nodes did not restore networking. -- 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/997978 Title: KVM images lose connectivity with bridged network To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/997978/+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
