Regarding comment #55: I don't believe this is a guest OS issue. In my comment #51 I also indicate that I have had non-precise vm's (specifically 11.10) experience the same issue.
I have only experienced this issue when using 12.04 precise as the host OS. On a customer server which I back-dated by reinstalling 11.10 as the host OS, the issue went away. -- 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/nova/+bug/997978/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
