i believe that we're seeing the same problem with ganeti-managed kvm instances running on 12.04 utilizing a bridged network.
in an initial deployment of 8 guests (also 12.04) we had half of them drop off the network within a few hours. there is a weak correlation between high network load in the guests and the network dropping. in some but not all cases from the kvm instance's console i was able to ifdown/ifup its interface and bring it back online. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
