Hi, as I'm setting up to reproduce this, I'm wondering exactly what to do with eth1. You are putting into br1, and leaving both eth1 and br1 unconfigured, at least according to interfaces(5). Are you later on manually configuring it? Then your vms get their nics also bridged to br1, so how you're configuring it is essential of course.
At the same time, what is eth1 physically plugged into? ** Changed in: qemu-kvm (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1172091 Title: KVM guests with bridged network drops out intermittently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1172091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
